Hematologic and renal improvement of monoclonal immunoglobulin deposition disease after treatment with bortezomib-based...
Monoclonal immunoglobulin deposition disease (MIDD) is characterized by non-organized immunoglobulin-fragments along renal basement membranes with subsequent organ deterioration. Treatment is directed against the immunoglobulin-producing clone. We treated 18 MIDD patients with bortezomib-based regimens (12 received bortezomib-dexamethasone, 6 bortezomib-dexamethasone with cyclophosphamide). Eleven (61%) patients achieved a hematologic response, but only 6 (33.3%) reached to a complete (CR) or very good partial response (VGPR). Regarding renal outcomes 77.8 and 55.6% had ≥30 and ≥50% reduction of proteinuria, respectively, but 33.3% ended up in end-stage renal disease (ESRD). Among patients with CR or VGPR, median eGFR improvement was 7.7 ml/min/1.73 m2 and none progressed to ESRD, but no significant renal recovery was observed in patients achieving a partial response or less, with 50% progressing to dialysis. Pretreatment eGFR seems to influence renal prognosis. Bortezomib-based treatment is ...

The pathogenesis of renal injury and treatment in light chain deposition disease | Journal of Translational Medicine | Full Text
Light chain deposition disease (LCDD) is a rare clinical disorder. The deposition of light chain immunoglobulins mainly affects the kidneys, which have different characteristics than other tissues. To date, the therapeutic approach for the treatment of LCDD has no evidence-based consensus, and clinical experience of reported cases guides current disease management strategies. The present systematic review investigates and summarizes the pathological mechanisms of renal injury and the subsequent treatments for LCDD.

Review question. What are the benefits and harms of treatments for nerve damage associated with abnormal IgG and IgA proteins in the blood?. Background. Paraproteinaemic neuropathy refers to those neuropathies associated with a paraprotein (an abnormal antibody or immunoglobulin (Ig) present in relative excess in the blood). Paraproteins come from a group of blood disorders called monoclonal gammopathies. If the paraprotein is present without evidence of any underlying disease, this is known as a monoclonal gammopathy of uncertain significance (MGUS). This review looked at the treatments for neuropathy associated with and possibly caused by IgG and IgA paraproteins. The optimal treatment is not known. Treatments that act on the immune system such as plasma exchange, corticosteroids or intravenous immunoglobulin have been examined in nonrandomised studies of people with IgG and IgA paraproteinaemic neuropathy.. Study characteristics. We identified only one randomised controlled trial (RCT), which ...

AU - Goeken, James A.. AU - Cancilla, Pasquale A.. PY - 1982/7. Y1 - 1982/7. N2 - A causal relationship between paraproteinemia and neuropathies has been suggested. We studied three patients with chronic sensorimotor polyneuropathy associated with plasma cell dyscrasia and monoclonal gammopathies (IgGK, IgMK, IgAX). Sural nerve biopsies showed mild (2 cases) to moderate loss of myelinated fibers (1 case). Teased single fiber studies showed segmental dcmyelination-remyelination in two patients. Direct immunofluorescence demonstrated immune deposits of the myelin sheath of the same specificity as the serum paraprotein, IgGK (1 of 3 cases). Treatment with prednisone, melphalan or chlorambucil, and plasmapheresis resulted in remission (1 case), partial improvement (1 case), or had no effect (1 case), although ...

Plasma cell dyscrasias are characterized by uncontrolled proliferation of a single clone of B cells which is responsible for the secretion of a monoclonal immunoglobulin (Ig) or Ig subunit that can become deposited in tissues. They can cause a wide range of renal diseases.Light-chain amyloidosis-renal presentation is usually with proteinuria, often progressing to nephrotic syndrome. Progressive decline in renal function usually occurs, leading finally to endstage renal failure. Diagnosis is made by the detection of monoclonal gammopathy in serum and/or urine (90% of cases) in combination with biopsy evidence of amyloid- forming light chain deposits. Chemotherapy with oral mephalan plus dexamethasone should be considered as first line treatment....

ANSWER: A Although glomerular disease in patients with CLL/SLL is less common, the most frequent patterns of glomerular injury seen include MPGN (immune complex mediated), MCD, membranous GN, and monoclonal immunoglobulin deposition disease. The most common form of kidney involvement in patients with CLL/SLL is the presence of direct infiltration of the kidney parenchyma by leukemic cells. Although glomerular disease in patients with CLL/SLL is less common, they can be present. The glomerular pattern of injury frequently seen in these group of patients include membranoproliferative glomerulonephritis (immune complex mediated), minimal change disease, membranous nephropathy, and monoclonal immunoglobulin deposition disease (nonamyloid ...

Hematologic Oncology
Hematologic oncology is determination, treatment and anticipation of blood diseases (hematology) and cancer (oncology) and research into them. Hematologic oncology incorporates such diseases as iron inadequacy anemia, hemophilia, sickle cell disease, the thalassemia, leukemia and lymphomas, and in addition to these there are cancers of different organs. Tumors of the hematopoietic and lymphoid tissues or hematopoietic and lymphoid tissues are tumors that influence the blood, bone marrow, lymph, and lymphatic system. Plasma cell dyscrasias are scatters of the plasma cells. Plasma cell dyscrasias are created because of strange multiplication of a monoclonal population of plasma cells that might possibly discharge recognizable levels of a monoclonal immunoglobulin or immunoglobulin part (Para protein or M protein). Interminable lymphocytic leukemia (CLL) is a sort of tumor of the blood and bone marrow - the supple tissue inside bones where platelets are made. Myelodysplastic or myeloproliferative ...
HD Melphalan and SCT in Patients With IGDD or LCDD - Full Text View - ClinicalTrials.gov
RATIONALE: Giving chemotherapy before a stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as G-CSF, and certain chemotherapy drugs, helps stem cells move from the bone marrow to the blood so they can be collected and stored. Chemotherapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy.. PURPOSE: This phase II trial is studying the side effects of high-dose melphalan given together with stem cell transplant and to see how well it works in treating patients with immunoglobulin deposition disease or light-chain deposition disease. ...

Consequences of the recurrent MYD88L265P somatic mutation for B cell tolerance | JEM
B cells must normally tolerate self-ligands of their pathogen-receptor systems (BCRs and TLRs) and only proliferate in response to foreign ligands for these receptors. The aforementioned experiments reveal that tolerance to nucleic acid-sensing TLRs is disrupted by a somatic mutation in MYD88 that is very frequently found in the benign disorder, IgM monoclonal gammopathy of undetermined significance, and in a range of B cell malignancies. In the absence of foreign TLR ligands, MYD88L265P was sufficient to drive multiple rounds of B cell division provided the Unc93b1-dependent and chloroquine-sensitive steps in TLR9 activation were intact, and provided the B cells were not constantly binding self-antigen. This disruption of normal tolerance to TLR9 has parallels with the effects of weakly activating lymphoma CARD11 mutations, which break normal B cell tolerance to self-ligands of the BCR (Jeelall et al., 2012). However breakdown of TLR tolerance is fortified by more checkpoint mechanisms: ...

Our results support the hypothesis that the number of genetically abnormal PC increases from MGUS to SMM and to MM. This observation was seen not only in those abnormalities considered secondary events, like 13q deletions, but also in IGH translocations, which are supposed to occur early in the disease pathogenesis (28, 29).. The present study shows that chromosomal abnormalities recurrently found in MM are also present in MGUS, including those abnormalities considered to be secondary genetic events, such as 13q and 17p deletions, and 1q gains, and even those associated with poor outcome such as 17p deletion t(4;14), and t(14;16). Interestingly, we found 7 MGUS patients with genetic abnormalities associated with dismal outcome, 4 with t(4;14), 2 with t(14;16), and 1 with 17p deletion, and none of them have progressed after a median follow-up of 45 months (range: 22-55 months).. Regarding the frequency of chromosomal abnormalities in the 3 PC dyscrasias, our study revealed a significantly lower ...

ICD-10-CM Code C90 - Multiple myeloma and malignant plasma cell neoplasms
Plasma cell dyscrasias are disorders of the plasma cells. Plasma cell dyscrasias are produced as a result of abnormal proliferation of a monoclonal population of plasma cells that may or may not secrete detectable levels of a monoclonal immunoglobulin or immunoglobulin fragment (paraprotein or M protein). Although the most common plasma cell dyscrasia is monoclonal gammopathy of undetermined significance (MGUS), closely related disorders include multiple myeloma, solitary plasmacytoma of bone, extramedullary plasmacytoma, Waldenströms macroglobulinemia (WM), primary amyloidosis, light chain deposition disease, paraproteinemia, and heavy-chain disease. The spectrum of MGUS, solitary plasmacytoma of bone, and asymptomatic and symptomatic multiple myeloma may actually represent a natural progression of the same disease. ...

Monoclonal gammopathy of undetermined significance is one of the most common pre-malignant disorders. IgG and IgA monoclonal gammopathy of undetermined significance are precursor conditions of multiple myeloma; light-chain monoclonal gammopathy of undetermined significance of light-chain multiple myeloma; and IgM monoclonal gammopathy of undetermined significance of Waldenstroms macroglobulinemia and other lymphoproliferative disorders. Clonal burden, as determined by bone marrow plasma cell percentage or M-protein level, as well as biological characteristics, including heavy chain isotype and light chain production, are helpful in predicting risk of progression of monoclonal gammopathy of undetermined significance to symptomatic disease. Furthermore, alterations in the bone marrow microenvironment of monoclonal gammopathy of undetermined significance patients result in an increased risk of venous and arterial thrombosis, infections, osteoporosis, and bone fractures. In addition, the small ...

Waldenströms macroglobulinemia - Wikipedia
Waldenströms macroglobulinemia (WM), also known as lymphoplasmacytic lymphoma, is a type of cancer affecting two types of B cells, lymphoplasmacytoid cells and plasma cells. Both cell types are white blood cells. WM is characterized by having high levels of a circulating antibody, immunoglobulin M (IgM), which is made and secreted by the cells involved in the disease. WM is an indolent lymphoma (i.e., one that tends to grow and spread slowly) and a type of lymphoproliferative disease which shares clinical characteristics with the indolent non-Hodgkin lymphomas. WM is commonly classified as a form of plasma cell dyscrasia. Similar to other plasma cell dyscrasias that, for example, lead to multiple myeloma, WM is commonly preceded by two clinically asymptomatic but progressively more pre-malignant phases, IgM monoclonal gammopathy of undetermined significance (i.e. IgM MGUS) and smoldering Waldenströms macroglobulinemia. The WM spectrum of dysplasias differs from other spectrums of plasma ...

Serum proteins and paraproteins in women with silicone implants and connective tissue disease: a case-control study | Arthritis...
The limited number of studies of serum proteins and paraproteins in women with silicone implants, and the lack of a controlled study taking into account CTD as an additional possible risk factor for serum protein abnormalities, prompted this case-controlled investigation. Paraproteinemia is most often associated with MGUS, which in turn may be a precursor of MM, macroglobulinemia, amyloidosis, or related diseases [21]. Subjects with MGUS often have autoantibodies [22] or autoimmune manifestations [23], and subjects with rheumatic diseases are reported to have higher rates of MGUS [15]. A critical aspect of our case-control study design was therefore to match subjects not only by age, but also by CTD diagnosis to minimize possible confounding. We also used highly sensitive agarose gel electrophoretic and immunofixation electrophoresis methods to maximize detection of serum paraproteins. Because it is possible that FMS patients may differ from inflammatory CTD in the risk of paraproteinemia, we ...

Recently, there have been substantial advances in techniques to detect, measure and characterize monoclonal gammopathies. For example, capillary zone electrophoresis can crisply separate serum components, detecting subtle monoclonal proteins. In addition, immunosubtraction (immunotyping) can aid in measuring M-proteins that co-migrate with other serum proteins. However, there interferences can result from a variety of substances including antibiotics and radiocontrast dyes. By use of real time audience response systems a variety of challenging and instructive cases will demonstrate the problems of false positive and false negative tests. The information will be synthesized into a practical approach to effective and efficient detection of M-proteins.. ...

MGUS is present in 1% of all adults (3% of those over age 50 years and more than 5% of those over age 70 years). Among all patients with paraproteins, MGUS is far more common than plasma cell myeloma. MGUS is defined as bone marrow monoclonal plasma cells less than 10% in the setting of a paraprotein (serum M-protein less than 3 g/dL [30 g/L]) and the absence of plasma cell-related end-organ damage. If an excess of serum free light chains (kappa or lambda) is established, the kappa to lambda ratio is 100 or less or 0.01 or greater. In approximately one-quarter of cases, MGUS progresses to overt malignant disease in a median of one decade. The transformation of MGUS to plasma cell myeloma is approximately 1% per year. Two adverse risk factors for progression of MGUS to a plasma cell or lymphoid malignancy are an abnormal serum kappa to lambda free light chain ratio and a serum monoclonal protein (M-protein) level 1.5 g/dL or greater. Patients with MGUS have shortened survival (median 8.1 years vs ...

Monoclonal Gammopathy of Undetermined Significance and Smoldering Multiple Myeloma: A Review of the Current Understanding of...
Using gene expression analyses, overexpression of the cyclin D genes seems to be one possible unifying event that is seen in almost all multiple myeloma cases with or without an immunoglobulin translocation as compared with normal plasma cells (30). IgH translocations directly dysregulate cyclin D1 or D3 [t(11;14) and t(6;14), respectively] and the C-MAF or MAFB transcription factors dysregulate cyclin D2 [t(14;16) and t(14;20); ref. 31]. In this study, 12 MGUS samples had a similar pattern of cyclin D dysregulation despite a lower proliferative index, suggesting that cyclin D perturbation may indeed be an early and unifying event in plasma cell dyscrasias.. MicroRNAs (miRNA) are single-stranded RNA molecules that regulate gene expression posttranscriptionally and are being implicated in a large number of cancers (32). A study comparing miRNA profiles of normal plasma cells (PC), MGUS, SMM, and multiple myeloma found overexpression of mir-21, mir-106∼25, and mir181a, and mir-181b in MGUS and ...
Final Diagnosis -- Case 448
DIAGNOSIS: LIGHT CHAIN DEPOSITION DISEASE (LCDD) OF THE BRAIN FOLLOWING CEREBRAL LOW-GRADE LYMPHOMA. DISCUSSION:. Monoclonal Ig deposition diseases (MIDD) are defined by tissue deposits of monotypic Ig heavy or light chains, the major cause being a clonal expansion of Ig-secreting plasma cells. The most common form of MIDD is light chain-derived amyloidosis (AL), characterized by Congo red staining of the deposits and green birefringence under polarization microscopy caused by the -pleated sheet arrangement of amyloid protein. Electron microscopy visualizes nonbranching fibrils with an accompanying pentagonal glycoprotein (P component). Immunohistochemically, the deposits stain monotypically for or chains, the latter predominating (Gallo 1986). In contrast, the less frequently recognized LCDD and the combined light and heavy chain deposition diseases (LHCDD) are characterized by deposits of non-fibrillary, amorphous material without -pleated sheet configuration, which makes them ...

Cancer immunoediting and immune dysregulation in multiple myeloma | Blood | American Society of Hematology
Avoiding immune destruction is a hallmark of cancer. Over the past few years, significant advances have been made in understanding immune dysfunction and immunosuppression in multiple myeloma (MM), and various immunotherapeutic approaches have delivered improved clinical responses. However, it is still challenging to completely eliminate malignant plasma cells (PCs) and achieve complete cure. The interplay between the immune system and malignant PCs is implicated throughout all stages of plasma cell dyscrasias including asymptomatic states called monoclonal gammopathy of undetermined significance and smoldering myeloma. While the immune system effectively eliminates malignant PCs or at least induces functional dormancy at early stages, malignant PCs eventually evade immune elimination, leading to progression into active MM, in which dysfunctional effector lymphocytes, tumor-educated immunosuppressive cells, and soluble mediators coordinately act as a barrier for anti-myeloma immunity. An in ...

Introduction. Waldenström macroglobulinemia is defined by the World Health Organization and the International Waldenströms Working Group as the presence of bone marrow lymphoplasmacytic lymphoma associated with a monoclonal IgM protein of any size. The bone marrow morphology shows both CD38 expressing plasma cells and CD20 expressing lymphoplasmacytic cells. A monoclonal protein is invariably visible on the serum protein electrophoresis. Immunofixation identifies an IgM heavy chain. One of the defining syndromes of Waldenström macroglobulinemia is the development of hyperviscosity due to the impact of pentameric IgM on the flow of serum. The most common signs of hyperviscosity are oronasal bleeding or blurred vision secondary to retinal hemorrhage.. IgM monoclonal serum proteins represent 18% of all monoclonal proteins seen. Since monoclonal gammopathy of undetermined significance (MGUS) is seen in 3% of adults over the age of 70, 1 adult in 200 will have an IgM monoclonal protein. However, ...

Solitary extramedullary plasmacytoma of prostate on the background of treated prostate adenocarcinoma - eSciPub Journals
Solitary Plasmacytoma is a rare entity which accounts for | 5% of all plasma cell dyscrasias. Most commonly involved sites for solitary extramedullary plasmacytoma are head and neck (90 %) especially upper respiratory tract, followed by Gastrointestinal tract. Rarely it can involve testes, bladder and orbit. PET/CT provides an invaluable imaging support for initial evaluation of additional plasmacytomas and response to treatment. There are no randomized trials regarding the best treatment approach. Generally, radiotherapy remains treatment of choice of solitary plasmacytoma. Our case, with its rare site of occurrence along with patients history of radiotherapy treated prostate malignancy and significant history of radiation cystitis provides a unique diagnostic and therapeutic challenge. Treatment can be personalised in cases such as this, where patients can be treated with chemotherapy in contrary to radiotherapy as further exposure to the radiations could exacerbate the bleeding risks.
Diagnosis and treatment of monoclonal gammopathy of renal significance
Monoclonal gammopathy of renal significance (MGRS) represents a group of kidney disorders caused by a monoclonal immunoglobulin that is secreted by anonmalignant or premalignantB cell or plasma cell clone. By definition, these disorders do not meet d
Evaluation of Multiple Models to Distinguish Closely Related Forms of Disease Using DNA Microarray Data: an Application to...
Motivation: Standard laboratory classification of the plasma cell dyscrasia monoclonal gammopathy of undetermined significance (MGUS) and the overt plasma cell neoplasm multiple myeloma (MM) is quite accurate, yet, for the most part, biologically uninformative. Most, if not all, cancers are caused by inherited or acquired genetic mutations that manifest themselves in altered gene expression patterns in the clonally related cancer cells. Microarray technology allows for qualitative and quantitative measurements of the expression levels of thousands of genes simultaneously, and it has now been used both to classify cancers that are morphologically indistinguishable and to predict response to therapy. It is anticipated that this information can also be used to develop molecular diagnostic models and to provide insight into mechanisms of disease progression, e.g., transition from healthy to benign hyperplasia or conversion of a benign hyperplasia to overt malignancy. However, standard data analysis ...

BACKGROUND: There are limited data on survival patterns among patients with monoclonal gammopathy of undetermined significance. DESIGN AND METHODS: We compared the survival of 4,259 patients with monoclonal gammopathy of undetermined significance, collected from hematology outpatient units in Sweden, with the survival of the general population by computing relative survival ratios. We also compared causes of death in these patients with those in 16,151 matched controls. RESULTS: One-, 5-, 10-, and 15-year relative survival ratios were 0.98 (95% CI 0.97-0.99), 0.93 (0.91-0.95), 0.82 (0.79-0.84), and 0.70 (0.64-0.76), respectively. Younger age at diagnosis of the gammopathy was associated with a significantly lower excess mortality compared to that in older patients (p,0.001). The excess mortality among patients with gammopathy increased with longer follow-up (p,0.0001). IgM (versus IgG/A) gammopathy was associated with a superior survival (p=0.038). Patients with monoclonal gammopathy of ...
Nephron Power: IN THE NEWS: Treating Cast Nephropathy without treating the myeloma!
This is an interesting study as it doesnt treat the underlying disease which is MM but is attempting to treat in an animal model a consequence of the disease. Cast nephropathy which leads to intra tubular obstruction can quickly lead to dialysis in many cases. This is a study that shows by using the CDR3 inhibitor, we prevent this bad light chain and THP combo and prevent the precipitation in the tubules. We also know that the free light chains behave differently in each MM case. In some cases, we get cast nephrpathy and in some cases we get light chain deposition disease and some amyloidosis. It appears to be characteristics of the specific light chains produced. While this method might be optimal for cast nephrpathy cases, dont know if this will prevent all MM associated renal diseases. Regardless, this study might lead to growing MM related cast nephropathy studies with this inhibitor; hopefully. ...
Radiation Oncology/Multiple myeloma - Wikibooks, open books for an open world
Conclusion: Serum IFE, PEL, and FLC combined with urine IFE and PEL is the most comprehensive and inclusive panel to screen for monoclonal gammopathies. However, because of the small incremental sensitivity provided by urine studies and serum IFE, the use of serum PEL plus FLC provides a simple and efficient initial diagnostic screen for the high-tumor-burden monoclonal gammopathies such as MM, WM, and SMM. Urine studies and serum IFE can be ordered more selectively ...

Light-Chain (AL) Amyloidosis: Diagnosis and Treatment | American Society of Nephrology
The nonspecific and often vague nature of symptoms that are associated with AL amyloidosis frequently leads to delays in diagnosis such that organ dysfunction is advanced by the time treatment is initiated. The diagnosis of AL amyloidosis should be considered in patients with unexplained proteinuria, cardiomyopathy, neuropathy, or hepatomegaly and in patients with multiple myeloma that has atypical manifestations.. The diagnosis of AL amyloidosis requires (1) demonstration of amyloid in tissue and (2) demonstration of a plasma cell dyscrasia. Tissue amyloid deposits demonstrate apple-green birefringence when stained with Congo red and viewed under polarizing microscopy. Fine-needle aspiration of abdominal fat is a simple procedure that is positive for amyloid deposits in ,70% of patients with AL amyloidosis (15,16). Other tissues that allow for relatively noninvasive biopsy procedures are the minor salivary glands, gingiva, rectum, and skin. However, obtaining tissue from an affected organ may ...

Current Projects: Blood Cancers | Damon Runyon
Multiple myeloma (MM) is an incurable cancer of blood cells. It evolves from monoclonal gammopathy of undetermined significance (MGUS), a pre-malignant condition affecting 3-5% of individuals older than 50 years. MGUS patients progress to MM at a rate of 1% per year and the mechanisms underlying such transformation are unknown. No genetic driver mutations have been identified in MM to date, thus limiting our therapeutic options. Signaling through the transmembrane receptor Roundabout1 (ROBO1) is important in solid tumors, particularly gastrointestinal cancer. In MM, ROBO1 expression level was found to correlate with adverse survival in newly diagnosed patients, and ROBO1 mutations have been recently identified in patient-derived MM cells. Dr. Bianchi aims to investigate whether ROBO1 is sufficient to promote disease pathogenesis and to identify the downstream signaling molecules responsible for its function. She anticipates that her results will provide new insights into disease biology and the ...

Roentgen Ray Reader: December 2014
Because the M-protein of patients with WM is almost always IgM, a broad differential should be considered for lucent bone lesions (the M-protein of multiple myeloma is usually IgG, followed by IgA and IgD, with IgM myeloma making up about 1% of cases). The same can be said for sclerotic bone lesions with or without peripheral neuropathy (the M-protein of POEMS is usually IgG and IgA, with IgM POEMS being very rare). However, this information is not always available when interpreting initial staging studies for patients with newly diagnosed plasma cell dyscrasia ...

ACBNI - 2012 Spring Scientific Meeting
The plan of the meeting was adventurous to say the least. We wanted to have a focus and yet be inclusive for the extended membership of the ACB, involving both our immunologist and microbiologist colleagues. I think we managed to pull it off! This was in most part due to the quality of preparation and delivery of the lectures by our invited speakers.. The morning session was focused mainly on cancer markers. Dr Dale Powner from The Binding Site explained the value of Freelite assays in the early detection of Monoclonal Gammopathies. He then introduced the potential of heavylite assays for the differential diagnosis within monoclonal gammoapathies, leaving us to consider the potential application of this new diagnostic tool. This was followed by a talk from the renowned expert in the field of Myeloma and MGUS, Professor Curly Morris entitled Myeloma - new drugs, new techniques, new outlook. In this talk he discussed the stages of a pre-existing MGUS period, of variable time period, leading to ...
Case of the month (February 2021) | Οφθαλμολογικό Κέντρο Ophthalmica
The major distinction to be done for corneal dystrophies (CD) is with corneal degeneration. Generally, CDs have a bilateral, symmetric presentation, unrelated to environmental factors. Most often, though, CDs must be differentiated among one another, as clinical presentations may overlap. Biomicroscopy helps in identifying different types of CD. Genetic testing may aid in final differentiation. Specifically, lesions in GCD type I can resemble a lot those found in monoclonal gammopathies.. Discussion and Literature. Corneal dystrophy is a collection of rare hereditary, non-inflammatory disorders of abnormal depositions in the cornea. As proposed in 2015 by the International Classification of Corneal Dystrophies (IC3D), CD is subclassified by anatomic location: epithelial/subepithelial, epithelial-stromal, stromal, and endothelial. There is no gender predilection There seems to be a higher prevalence among Caucasian individuals. Clinical manifestation depends on the involved corneal layer(s). ...
