N2 - A 31-year-old man was admitted to our hospital because of a sudden onset of thirst, polyposia, and polyuria. Five years previously he had been admitted to our hospital because of a dry cough. On the first admission, the chest X-ray film had shown reticular shadows and bullous changes in both upper lung fields. Histological examination of a transbronchial lung biopsy specimen had revealed that the nodular lesion in the interstitium of the alveolar lesion consisted of an aggregate of many Langerhans cells with pale cytoplasm and partly convoluted nuclei. In addition, immunoperoxidase stain for S-100 protein had been strongly positive in numerous Langerhans cells in a bone biopsy specimen from a left mandibular lesion, which is the same histological appearance as the lung lesion. A diagnosis of ...

An eosinophil is a type of white blood cell that is commonly associated with allergic responses or with parasitism. Eosinophil counts will go up on a blood test when a pet has fleas or worms or when an allergy is flaring up. Eosinophilic granulomas could arise from any number of primary skin condition.

A granuloma is a solid grouping of inflammatory cells coming together in a solid structure. An eosinophil is a type of white blood cell that is commonly associated with allergic responses or with parasitism. Finding eosinophils in tissue suggests allergic disease usually whereas finding increased eosinophil numbers in a blood sample more commonly suggest parasitism. Sometimes proliferations grow from the actual footpads where they ulcerate as the cat is forced to walk on them. There is some tendency for this condition to occur in adolescent kittens though it can occur at any age. The eosinophilic granuloma complex represents a disorder of eosinophil function. The eosinophils real job is to attack parasites. In cats with eosinophilic granuloma complex, eosinophils are called to the site of an allergic response and the biochemicals released cause damage to local collagen. For more ...
LCH predominantly affects children and is comprised of three conditions: eosinophilic granuloma, Hand-Schuller-Christian disease, and Letterer-Siwe disease. All three conditions are characterized by the presence of abnormal histiocytes called Langerhans cells. Eosinophilic granuloma is the mildest form and is the most common, comprising approximately 70% of the disease. It consists of single or multiple bony lytic lesions, and most commonly involves the skull, mandible, spine, ribs, and long bones. Hand-Schuller-Christian disease (20% of LCH) is a multisystem disease comprised of diabetes insipidus, exopthalmos, and one or multiple bony lesions. It is fatal in approximately 30% of patients. Letterer-Siwe disease (10% of LCH) is the most severe form and it affects children less than three years old with liver, spleen, skin, and bony involvement. It is usually fatal within two years of diagnosis ...
ONE OF the most interesting recent developments in the field of pathology is the concept, first advanced by Farber and Green,1 that eosinophilic granuloma of b
When dealing with the pruritic cat there is a tendency for veterinarians to diagnosis the reaction pattern of the pruritus rather than the true etiology. This is especially true for the (in) famous eosinophilic granuloma complex (EGC). Some people have referred to the EGC as the eosinophilic granuloma confusion.. The first step is reviewing the signalment. Kittens are most likely to have ectoparasites (e.g., otoacariasis, notoedric acariasis) or dermatophytosis as their underlying disease. Young adult cats are more likely to have atopy or cutaneous adverse food reactions (CAFR) than kittens, but remember they too can have ectoparasites or dermatophytosis as their underlying disease. Next step is to obtain a detailed history. If the cat has had previous skin or ear disease, getting a copy of the medical records may help tremendously in developing a differential diagnosis list. Then, question life style, diet, other animals in the household and any medications they are currently using. Also ask, ...

During the last few years occasional reports have appeared in the literature concerning a group of diseases of the reticuloendothelial system which have the appearance of inflammatory granulomas and are thought to be of infectious origin, although the etiology is still unknown. They have many of the characteristics of neoplasms, but they are not true tumors, since they grow by the addition of cells and not by cell division.. European investigators1 had previously called attention to the intimate relationship between eosinophilic granuloma of bone, Hand-Schüller-Christian disease and Letterer-Siwe disease as interrelated manifestations of the same fundamental pathologic process. But it ...
Eosinophilic ulcer of the oral mucosa is a benign, rare, self-limiting, and generally asymptomatic lesion that shows spontaneous regression. Its etiopathogenesis is still uncertain, but trauma seems to play a fundamental role in the occurrence of this tumor. Clinically, this lesion manifests as an isolated ulcer preferentially located on the tongue, showing a raised and indurated border in addition to a white or yellowish bed. Microscopically, eosinophilic ulcer is characterized by an inflammatory infiltrate rich in leukocytes. Since these lesions show spontaneous cure, treatment becomes unnecessary, but in certain cases, cure is obtained by excision of the ulcer during biopsy. In these cases, the differential diagnosis with squamous cell carcinoma is made. A case of very small eosinophilic ulcer of the oral mucosa located on the lateral border of the tongue is presented. (Quintessence Int 2007; 38:677 680) Key words:eosinophilic granuloma, eosinophilic ulcer, oral mucosa, tongue, trauma, ...
Category General Spine Aaron Baer, MD Mohannad Ibrahim, MD Colin McKnight, MD Hemant Parmar, MD Purpose The purpose of this educational exhibit is to examine the characteristic imaging features, epidemiology, and clinical presentations of common solitary osseous lesions of the spine. Materials & Methods The following osseous lesions of the spine were compared in terms of their characteristic imaging features, typical anatomic distributions, patient demographics, and clinical presentations: aneurysmal bone cyst, chordoma, enostosis, eosinophilic granuloma, Ewing sarcoma, giant cell tumor, hemangioma, lymphoma, metastases, myeloma, osteoblastoma, osteoid osteoma, osteomyelitis, osteosarcoma, and Paget disease. Patient cases were collected and graphic illustrations were used to demonstrate the unique imaging characteristics of each entity and the similarities among them. Results There are several solitary osseous lesions which have unique imaging features (e.g. hemangioma), patient demographics ...
Cat skin disorders are among the most common health problems in cats. Skin disorders in cats have many causes, and many of the common skin disorders that afflict people have a counterpart in cats. The condition of a cats skin and coat can also be an important indicator of its general health. Skin disorders of cats vary from acute, self-limiting problems to chronic or long-lasting problems requiring life-time treatment. Cat skin disorders may be grouped into categories according to the causes. Skin disease may result from deficiencies in immune system function. In cats, the most common cause of immune deficiency is infection with retroviruses, FIV or FeLV, and cats with these chronic infections are subject to repeated bouts of skin infection and abscesses. This category also includes hypersensitivity disorders and eosinophilic skin diseases such as atopic dermatitis, miliary dermatitis and feline eosinophilic granuloma and skin diseases caused by autoimmunity, such as pemphigus and discoid ...
Its not just for teenagers anymore - cats can get acne too!. You may see your cat rubbing his chin against the furniture or other corners more than usual. You might notice little black specks around your cats lips or chin (especially in a cat with a light-colored face), or you might not have a clue until you see an oozing abscess draining from the jaw. Often the chin will become lumpy with "pimples.". Feline acne usually involves a bacterial infection. However, other conditions can cause similar-appearing lesions, including skin mites, ringworm, yeast infection, or auto-immune diseases such as eosinophilic granuloma complex ("rodent ulcers"). If you do notice something going on in the chin area, a trip to the veterinarians office is your best bet to make sure the problem is not more serious than a few zits!. The most common cause/contributor to the problem is use of plastic food bowls. Plastic is porous, and bacteria can lodge in the crevices. The bacteria remain there, safe and inaccessible ...

Introduction. Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic vasculitis that is commonly associated with cutaneous involvement (40%-81%).1-3. Case Report. The patient was a 53-year-old man with a history of rhinitis, asthma and eosinophilic pneumonia, diagnosed 4 years earlier, who presented with pruritic lesions on the scalp that had developed 7 days before. There were 4 circular plaques measuring 2-4cm, that were skin-colored or erythematous, with an infiltrated border and small scabs (Fig. 1A and C). Biopsy revealed a superficial inflammatory infiltrate made up of lymphocytes and eosinophils; there were neutrophils in the vessel wall, with no fibrinoid necrosis; we also detected histiocytes interspersed with degenerated collagen in the superficial and reticular dermis (Fig. 1B). Direct immunofluorescence and Ziehl-Neelsen staining were negative. We found leukocytosis with 15,900cells/μL; eosinophilia (24.7%; 3900cells/μL); and complement C3 of 83.7mg/dL. Antinuclear ...
Langerhans cell histiocytosis previously known as histiocytosis X is a rare disease of children and young adults with a very broad clinical spectrum. In children, its annual incidence is estimated between 0.2-0.5 per 100,000. An 8-year-old Moroccan girl with no known personal or family history presented to our institution with painful swelling of both forearms. An X-ray and magnetic resonance imaging were inconclusive. We then performed a biopsy curettage (of her left forearm). Microscopic analysis followed by immunohistochemical analysis disclosed a diagnosis of Langerhans cell histiocytosis. No chemotherapy was necessary. Clinical and radiological improvement was achieved after 6 months. The particularity of this observation is the bilaterality of the lesion on both forearms and it has not previously been reported. Langerhans cell histiocytosis should be included in the differential diagnosis of osteomyelitis and Ewings sarcoma.
Eosinophilic granulomatosis with polyangiitis (EGPA; also known as Churg-Strauss syndrome [CSS] or allergic granulomatosis) is an extremely rare autoimmune condition that causes inflammation of small and medium-sized blood vessels (vasculitis) in persons with a history of airway allergic hypersensitivity (atopy). It usually manifests in three stages. The early (prodromal) stage is marked by airway inflammation; almost all patients experience asthma and/or allergic rhinitis. The second stage is characterized by abnormally high numbers of eosinophils (hypereosinophilia), which causes tissue damage, most commonly to the lungs and the digestive tract. The third stage consists of vasculitis, which can eventually lead to cell death and can be life-threatening. This condition is now called "eosinophilic granulomatosis with polyangiitis" to remove all eponyms from the vasculitides. To facilitate the transition, it was referred to as "eosinophilic granulomatosis with polyangiitis (Churg-Strauss)" for a ...
Letterer-Siwe disease is an old name for Langerhans cell histiocytosis (LCH), from a time when LCH was thought to be several different diseases; Letterer-Siwe disease, Hand-Schuller-Christian disease, Eosinophilic granuloma and Hashimoto-Pritzker disease. Later they were all put together under the name Histiocytosis X. The X was found to be the Langerhans cell, a dendritic white blood cell. LCH is not believed to be genetic, even though there have been a few reports of more than one person affected by LCH within the same family. Still to this day, the cause is unknown, after researchers have worked very hard on trying to figure it out for decades. ...
Langerhans cell h. Any of a number of clinical conditions, most commonly seen in infants and children, caused by disease of Langerhans cell histiocytes. These cells, which are characteristic of all of the variants of the disease, cause granulomas. The great variation in the signs and symptoms produced depends upon their location and how widely spread they are. Almost any organ system including the skeleton may be involved. These diseases were previously given names such as histiocytosis X, Hand-Schüller-Christian disease, Letterer-Siwe disease, and eosinophilic granuloma. Treatment may consist of surgical removal of bone lesions and radiation therapy for lesions threatening vital functions such as sight and hearing. Corticosteroids or cytotoxic agents are useful in controlling soft-tissue disease and multiple skeletal lesions. Bone marrow transplantation has been used in recurrent and progressive Langer-hans cell histiocytosis. ...
The bony mass had a cartilage cap and the tentative diagnosis of an osteochondroma was made. The patient was not known to have any other exostoses.. Intra-operatively a bony mass with a cartilage cap was found, compressing the L5 and S1 spinal root. The mass was excised and sent for histology. A laminectomy was done.. The histology confirmed an osteochondroma.. Discussion. Of all spinal tumours, 70% of primary bone tumours are benign. These include osteoid osteomas, osteoblastomas, giant cell tumours, osteochondromas, aneurysmal bone cysts, eosinophilic granulomas and fibrous dysplasias.1. Osteochondromas (also known as osteocartilaginous exostoses)2 encompass 10-15% of all bone tumours3 and 36% of all benign bone tumours.4 Primary tumours of the spine are relatively infrequent when compared to lymphoma of the spine, myeloma and multiple myeloma.5. Osteochondromas are solitary (often) and are cartilaginous bony growths, usually appearing in relation to the epiphyseal growth plate.6 They can be ...
Results 41 patients (21 women) with EGPA treated with rituximab between 2003 and 2013 were identified. 15 (37%) had refractory, 21 (51%) relapsing and 5 (12%) new onset disease. 19 received a single course and 22 received repeat-dose rituximab to prevent relapse. By 6 months, 83% improved with remission in 34% and partial response in 49%, and by 12 months 49% were in remission and 39% had a partial response. Prednisolone doses decreased in all patients by 6 and 12 months. Antineutrophil cytoplasmic antibody positivity at baseline was associated with a higher remission rate at 12 months. Adverse events included 15 infections (6 were severe). ...
GSK announces NEJM publication of positive phase III study investigating mepolizumab in patients with Eosinophilic Granulomatosis with Polyangiitis (EGPA)
EGPA, also known as allergic granulomatosis angiitis, is a systemic vasculitis. EGPA is marked by three distinct symptoms: asthma; eosinophilia, evidenced by an excessive number of eosinophils in the blood and tissues; and vasculitis involving the skin, lungs, nerves, kidneys, and other organs. Nerve involvement may also occur in EGPA, causing pain, tingling, numbness, and muscle wasting in the hands and feet. Because EGPA patients may not show any visible signs of active disease, current methods of monitoring disease progression usually represent a period of extended inflammation and disease activity. Thus, patients may go untreated during a period of undetectable disease when damage might be preventable. This study will use novel scientific methods to identify new biomarkers that can be used to monitor disease activity in EGPA patients. These biomarkers may be used to help direct clinical care for EGPA patients and assist in future drug development.. Study visits will occur monthly for the ...
Results A 14-year-old male previously misdiagnosed as cutaneous anthrax was referred with a 2-month history of multiple wide and deep ulceronecrotic lesions in lower extremities, started after contact with animals (1a). Complete blood count (CBC) revealed anemia (hemoglobin: 8.5 g/dl, hematocrit: 26.9%), eosinophilia (4100/mm3) and thrombocytopenia (34000/mm3). Peripheral blood smear also revealed marked eosinophilia (42%). Infectious etiologies such as cutaneous anthrax, leishmaniosis, aspergillosis and nonspecific agents were excluded by gram staining, wound-blood-bone marrow cultures and serological investigations. Bone marrow aspiration was performed owing to the prominent eosinophilia, anemia and thrombocytopenia. However, the result was also pointing out eosinophilia without signs of eosinophilic leukemia. Although ANCAs were negative, the robust clinical manifestations concordant with EGPA (e.g. eosinophilia, increased Ig E level, history of asthma, vasculitic lesions) had led us to ...
The exact mechanism of pathogenesis for EGPA is currently unknown. However, it is generally thought to be due to a dysregulation of immune function. Research indicates that eosinophil infiltration and antineutrophil cytoplasmic antibody (ANCA)-induced endothelial damage may be involved in the underlying disease mechanism. About half of patients with EGPA have positive ANCA. Recently, it has been suggested that 2 distinct phenotypes of EGPA are present and depend on the presence or absence of ANCA. Several medications (eg, leukotriene modifying agents, omalizumab) have also been found to be associated with the apparent onset of EGPA; however, causal relationships have not been established, and it is likely that these medications only served to unmask the underlying disease ...
Eosinophilic Granulomatosis with Polyangiitis is a very rare subgroup of asthma. It is a combination of eosinophilic, granulomatosis with polyangiitis, and airway inflammation.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of Langerhans cell histiocytosis, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may be an effective treatment for Langerhans cell histiocytosis.. PURPOSE: This randomized clinical trial is studying combination chemotherapy to see how well it works in treating young patients with Langerhans cell histiocytosis. ...

Movie 3 Movie 4. Conclusion:This case demonstrates the range of cardiac involvement in Churg-Strauss syndrome is beyond that of cardiac hypereosinophilia characterised by myocarditis, endomyocardial fibrosis, intracardiac thrombus and heart failure. Coronary arteritis and acute infarction is increasingly reported in these patients1,2. Churg-Strauss syndrome is primarily characterised by vasculitis affecting both small and medium-sized blood vessels. Cardiac findings are present in about 50% of cases and are responsible for almost half of all deaths3. Cardiac involvement is reported to be more frequent in the ANCA- negative phenotype4. It has also been shown that the cardiac involvement is common even when their vasculitis is in clinical remission as was seen in this highlighted case5. CMR scanning this patient helped differentiate eosinophilic myocarditis from myocardial infarction by using tissue characterisation and the coronary pattern of late enhancement. The patients therapy was changed to ...
Indeterminate cell histiocytosis is a rare disease belonging to the group of malignant histiocytic diseases. The disease predominantly affects the skin. The disease appeared in the described patient at the age of 80 years. Morphs began to develop on the skin and rapidly spread over the whole body including the face. Only the hands and feet were left uncovered. The patients skin samples were taken from 2 sites for histological examination. The resulting conclusion was indeterminate cell histiocytosis. The treatment we chose was analogous to the procedures for Langerhans cell histiocytosis. We chose PUVA phototherapy as the first-line treatment. This treatment is frequently efficient for skin forms of Langerhans cell histiocytosis. In the described case, however, PUVA phototherapy did not influence the disease activity at all. As the second-line treatment, we used low-energy electron beam irradiation in the total dose of 36.2 Gy. This treatment had a positive impact, morphs began to diminish and slowly
Langerhans cell histiocytosis (LCH) is a rare disorder characterized by abnormal proliferation of cells with a Langerhans cell phenotype, which comprises a wide range of clinical presentations. The reported patient is a 55-year old female with multy-sistem LCH and pulmonary tuberculosis. During diagnostic processing, infiltrates of Langerhans cells (S-100+, CD1a+) in the epidermis, intestinal mucosa and bone marrow, were discovered. Transbronchial needle biopsy of the lung revealed non-specific clusters of macrophages (CD68+, CD1a-). Although CD1a was negative, positive CD68, thoracic MSCT and clinical findings indicated pulmonary LCH. Corticosteroid treatment led to significant clinical improvement. Seven months after treatment with corticosteroids the patient developed a spontaneous left-sided pneumothorax. Thoracic HR (high resolution)-MSCT was highly suggestive for active Mycobacterium tuberculosis (MT) infection together with the positive QUANTIFERON-TB test and typical symptoms. One week after
Langerhans cell histiocytosis (LCH) is a rare disorder caused by monoclonal Langerhans cells proliferation in bone, skin, lung, lymph nodes, liver, spleen, nervous or hematopoietic system. Pulmonary LCH is a diagnostic trap that is displayed on computed tomography (CT) as an interstitial disorder with honeycomb aspect. In this paper, we present an unusual case of a 26-year-old female that was hospitalized with progressive worsening dyspnea and history of recurrent pneumonia. Lung biopsy showed fibrosis of the interalveolar septa, architectural distortion and large cells with foamy cytoplasm and convoluted nuclei that were marked by CD68, S-100 and the specific antibody CD1a that allowed establishing the diagnosis of pulmonary LCH ...

Only three cases of patients suffering from a localized chronic form of Langerhans cell histiocytosis (LCH) successfully treated with radiofrequency ablation (RFA) have been published so far. This is the first case report of a patient with a localized chronic form of LCH of the femur, which was successfully treated with percutaneous image-guided RFA, and who was evaluated pre-RFA and followed up post-RFA for a period of 48 months, in order to validate the safety and efficacy of this method and to obtain imaging studies depicting the actual in situ changes taking place post-RFA.
Langerhans cell histiocytosis is a rare disease. Depending on which organs are involved, the disease may prove rapidly fatal, develop a chronic reactivating but therapy-responsive pattern or resolve spontaneously. Understanding of the pathology of the disease is progressing rapidly, and while clinical trials of standard chemotherapy agents continue, it is likely that novel targeted therapy will become feasible in the next decade. Permanent consequences of the disease are more commoner than generally realised.. ...

Proteomic analysis of BAL revealed 59 spots expressed with quantitative differences and 9 spots expressed with qualitative differences in BAL of PLCH patients with respect to controls. The proteins identified from these spots are involved in specific biological mechanisms (inflammation, immunity, oxidative stress, protease-antiprotease balance, cell proliferation, fibrosis) potentially implicated in the pathogenesis of PLCH. Some of these proteins need to be studied in detail, as they could be useful diagnostic or prognostic biomarkers.. Two proteins never described in BAL were identified de novo: serpin B3 and plastin 2. The first, up-regulated in smokers and higher (with borderline significance p = 0.05) in PLCH than controls, is a member of the family of protease inhibitors involved in cell survival and associated with lung cancer [24]. The second protein, plastin 2, member of a large family of actin filament cross-linkers, was down-regulated in PLCH patients with respect to smoker controls. ...
