Choroid Neoplasms
Tumors of the choroid; most common intraocular tumors are malignant melanomas of the choroid. These usually occur after puberty and increase in incidence with advancing age. Most malignant melanomas of the uveal tract develop from benign melanomas (nevi).
Choroid Plexus
A villous structure of tangled masses of BLOOD VESSELS contained within the third, lateral, and fourth ventricles of the BRAIN. It regulates part of the production and composition of CEREBROSPINAL FLUID.
Choroid
The thin, highly vascular membrane covering most of the posterior of the eye between the RETINA and SCLERA.
Choroid Plexus Neoplasms
Benign or malignant tumors which arise from the choroid plexus of the ventricles of the brain. Papillomas (see PAPILLOMA, CHOROID PLEXUS) and carcinomas are the most common histologic subtypes, and tend to seed throughout the ventricular and subarachnoid spaces. Clinical features include headaches, ataxia and alterations of consciousness, primarily resulting from associated HYDROCEPHALUS. (From Devita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2072; J Neurosurg 1998 Mar;88(3):521-8)
Papilloma, Choroid Plexus
A usually benign neoplasm that arises from the cuboidal epithelium of the choroid plexus and takes the form of an enlarged CHOROID PLEXUS, which may be associated with oversecretion of CSF. The tumor usually presents in the first decade of life with signs of increased intracranial pressure including HEADACHES; ATAXIA; DIPLOPIA; and alterations of mental status. In children it is most common in the lateral ventricles and in adults it tends to arise in the fourth ventricle. Malignant transformation to choroid plexus carcinomas may rarely occur.

Ultrasonic characterisation of malignant melanoma of choroid. (1/324)

An in-vitro study of wave spectral analysis in 8 enucleated eyes was conducted in order to differentiate histological subtypes of malignant melanoma. To obtain the backscattering coefficient for the tissues, we used a broadband focussed transducer with a frequency range of 7-12 MHz and a centre frequency of 10 MHz. Experimental measurement of backscattering coefficient and attenuation coefficient at various frequencies was done by substitution techniques. The backscattering coefficient, scatterer size, and root mean square velocity fluctuation were derived by the numerical method, while the attenuation coefficient at 1 MHz was derived from attenuation coefficient at different frequencies. This study revealed that backscattering coefficient and attenuation coefficient, over a frequency range of 7-12 MHz, show an increase in the spindle cell type compared to the mixed cell type of malignant melanoma. Particularly, the scatterer size was significantly higher in the spindle cell group (p = 0.013) in contrast to the mixed cell type. Spindle cells have uniform and compact histological pattern which contributes to an increase in scatterer size and root mean square velocity fluctuation. The ultrasonically obtained parameters have been shown to have a good correlation with the histology of malignant melanoma.  (+info)

Radioactive phosphorus uptake testing of choroidal lesions. A report of two false-negative tests. (2/324)

Two false-negative results from 32P testing for histologically verified malignant melanomas of the choroid are reported. In the first case, a haemorrhagic choroidal detachment caused an increase in probe; additionally, the tumour was necrotic. Both factors are likely to have contributed to the false-negative result. A satisfactory explanation for the false-negative result in the second case was not determined, although it may have accurately reflected a period of minimal tumour activity, inasmuch as repeat 32P testing was strongly positive eight months later, when unequivocal evidence of tumour growth was present. An alternative explanation is that the orally administered 32P was incompletely absorbed. Since 32P testing is frequently accompanied by significant manipulation both in the manoeuvre associated with tumour localization and in that associated with the actual radioactive counting, it would seem desirable to perform indicated enucleation immediately after completion of the 32P testing. While the properly performed 32P test remains a valuable diagnostic test for helping to establish the presence or absence of malignancies of the posterior globe, it is important to guard against the tendency to underestimate careful clinical evaluation.  (+info)

Combination chemotherapy for choroidal melanoma: ex vivo sensitivity to treosulfan with gemcitabine or cytosine arabinoside. (3/324)

Treatment of choroidal melanoma by chemotherapy is usually unsuccessful, with response rates of less than 1% reported for dacarbazine (DTIC)-containing regimens which show 20% or more response rates in skin melanoma. Recently, we reported the activity of several cytotoxic agents against primary choroidal melanoma in an ATP-based tumour chemosensitivity assay (ATP-TCA). In this study, we have used the same method to examine the sensitivity of choroidal melanoma to combinations suggested by our earlier study. Tumour material from 36 enucleated eyes was tested against a battery of single agents and combinations which showed some activity in the previous study. The combination of treosulfan with gemcitabine or cytosine arabinoside showed consistent activity in 70% and 86% of cases, respectively. Paclitaxel was also active, particularly in combination with treosulfan (47%) or mitoxantrone (33%). Addition of paclitaxel to the combination of treosulfan + cytosine analogue added little increased sensitivity. For treosulfan + cytosine arabinoside, further sequence and timing experiments showed that simultaneous administration gave the greatest suppression, with minor loss of inhibition if the cytosine analogue was given 24 h after the treosulfan. Administration of cytosine analogue 24 h before treosulfan produced considerably less inhibition at any concentration. While we have so far been unable to study metastatic tumour from choroidal melanoma patients, the combination of treosulfan with gemcitabine or cytosine arabinoside shows activity ex vivo against primary tumour tissue. Clinical trials are in progress.  (+info)

Differential expression of the retinoblastoma gene family members in choroidal melanoma: prognostic significance. (4/324)

We evaluated 55 samples of choroidal melanoma managed by enucleation. Knowing that the immunohistochemical expression of the retinoblastoma gene family members Rb/p105, p107, and pRb2/p130 was inversely correlated with the degree of malignancy in at least some histological types, we investigated the expression of these three proteins in choroidal melanoma. We focused on the relationship between patient survival and the immunohistochemical detection of the retinoblastoma proteins. No correlation with clinical outcome was found for Rb/p105 and p107. However, we found pRb2/p130 to be an independent prognostic factor correlating positively or directly with patient survival times and indirectly or inversely with the degree of malignancy. Demonstration of the prognostic value of the immunohistochemical expression of pRb2/p130 is of significance, even if additional studies are required to confirm these data and to compare the prognostic value of pRb2/p130 immunodetection to that of other recently proposed markers, such as p53.  (+info)

Alpha/beta- and gamma/delta TCR(+) lymphocyte infiltration in necrotising choroidal melanomas. (5/324)

AIM: To detect specific tumour infiltrating T cells (TIL) carrying antigen specific MHC-I restricted receptor genes on necrotising and non-necrotising malignant melanomas and to correlate the findings with clinical data. METHODS: alpha/beta- and gamma/delta- TIL were determined by immunohistochemical staining in melanomas of patients with known follow up of more than 10 years. An antigen retrieval method was used to determine variable genes delta1 and gamma1 on TCR(+) cells by an anti-TCR Vdelta1 and anti-CrgammaM1, and of Valpha and Vbeta TCR(+) by an anti-pan-TCR(+) alpha/beta antibody. RESULTS: Intratumoral TIL were present in 86 of 113 (76.1%) necrotising melanomas (NMM) v 21 of 100 (21%) in non-necrotising melanomas (MM); of these, Valpha/beta- TCR(+) cells were present in 52 of 74 (70.3%) TIL harbouring NMM v four of 21 (19%) MM; Vgamma1 in 29 of 74 (39.2%) NMM v two of 21 (10%) MM; and Vdelta1 in 39 of 74 (52.7%) NMM v three of 21 (14%) MM. Extratumoral lymphocytic infiltration was seen in 86 (76.1%) NMM including Valpha/beta TCR(+) cells in 10 (11.6%) cases, v five (5%) MM cases with no Valpha/beta TCR(+) cells detected. Vgamma1 and Vdelta1 TCR(+) cells were not found in extratumoral infiltrates. CONCLUSIONS: In NMM, the median survival was 69.3 (range 6-237) months, 19 of 74 patients (25.7%) survived 5 years, and mortality was associated with advanced stage (p<0.001), patient age (p<0.023), and extent of necrosis (p<0.048). Survival was increased with evidence of Vgamma1 and Vdelta1 TCR(+) cells (p<0.026).  (+info)

Microvascular density in predicting survival of patients with choroidal and ciliary body melanoma. (6/324)

PURPOSE: Although malignant uveal melanoma disseminates predominantly hematogenously because of the absence of intraocular lymphatics, consensus about prognostic impact of microvascular density (MVD) has not been reached. This study was undertaken to investigate whether MVD, microvascular patterns, or both determine prognosis of uveal melanoma. METHODS: A population-based retrospective cohort study of melanoma-specific and all-cause mortality of 167 consecutive patients who had an eye enucleated because of choroidal or ciliary body melanoma from 1972 through 1981 was conducted. MVD was determined by counting tumor vessels in a masked fashion from areas of highest vessel density after immunostaining for CD34 epitope, factor VIII-related antigen (FVIII-RAg), and alpha-smooth muscle actin (SMA). Kaplan-Meier and Cox regression analyses of survival were performed. The association between MVD and tumor size and location, cell type, and microvascular patterns was assessed. RESULTS: MVD could be determined from 134 of 167 melanomas (80%). Based on globally highest count obtained with antibodies to CD34, MVD ranged from 5 to 121 vessels/0.313 mm2 (median, 40) and its association with presence of microvascular loops and networks (P = 0.0006), epithelioid cells (P = 0.028), and largest basal tumor diameter (P = 0.0029) was statistically significant. The 10-year melanoma-specific mortality increased with MVD (0.09, 0.29, 0.59, and 0.64, according to quartiles; P < 0.0001), as did all-cause mortality (P = 0.0022). Equivalent results were obtained with immunostaining for FVIII-RAg, whereas MVD obtained with antibodies to SMA was not associated with prognosis. Cox regression showed a hazard ratio of 2.45 (95% CI, 1.43-4.18) for presence of epithelioid cells, 1.11 (95% CI, 1.03-1.20) for largest basal diameter, 1.23 (95% CI, 1.06-1.43) for square root-transformed MVD, and 1.51 (95% CI, 1.09-2.10) for presence of loops and networks, all of which independently contributed to prognosis. CONCLUSIONS: The findings support the theory that both MVD and microvascular patterns contribute independently to prognosis in uveal melanoma in addition to cell type and size of the tumor.  (+info)

Ocular arterial blood flow of choroidal melanoma eyes before and after stereotactic radiotherapy using Leksell gamma knife: 2 year follow up. (7/324)

AIMS: To evaluate the effect of high dose stereotactic radiotherapy on the ocular blood flow of patients with uveal melanoma. METHODS: Colour Doppler imaging (CDI) was used to measure blood flow velocity and vascular resistance in the ophthalmic, short posterior, and central retinal arteries of nine patients suffering from uveal melanoma. The measurements were taken before, 6 months, 1 year, and 2 years after stereotactic radiotherapy. Irradiation was performed with the Leksell gamma knife with the 59 (41-66.5) Gy total marginal dose divided in two equal fractions. CDI results were compared with age and sex matched healthy control eyes. RESULTS: At each time of measurement, blood flow velocity in the central retinal artery of the affected eyes was significantly reduced whereas vascular resistance was only increased at the 2 year follow up. Blood flow velocity and vascular resistance in the short posterior arteries of melanoma eyes were also only significantly altered at the 2 year follow up. Blood flow velocity and vascular resistance in the ophthalmic artery of melanoma eyes were not changed at all follow ups. CONCLUSIONS: In the melanoma eyes, blood flow velocity in the central retinal artery is reduced. High dose stereotactic radiotherapy with the Leksell gamma knife and a 59 (41-66.5) Gy total marginal dose in two fractions leads to a significant reduction of blood flow and a significant increase in resistance variables in the small ocular arteries within 2 years.  (+info)

Transpupillary thermotherapy as primary treatment for small choroidal melanomas. (8/324)

PURPOSE: To report short-term follow-up of eyes containing small choroidal melanomas that were treated with transpupillary thermotherapy (TTT). METHODS: Twenty eyes with suspected small choroidal melanomas were treated with TTT using infrared light delivered from the diode laser. RESULTS: The age of patients ranged from 26 to 82 years. In 14, there was documented growth of the melanoma prior to TTT. Tumor thicknesses ranged from less than 1 to 3.2 mm. Seven tumors were treated more than once. Follow-up ranged from 6 months to more than 3 years. Following treatment, tumor thicknesses decreased in all cases, usually within 2 months. Progressive atrophy of tumor mass and loss of pigmentation within the tumor continued beyond 1 year of follow-up in some eyes. Complications included field defects, vascular changes, and macular abnormalities. CONCLUSIONS: Transpupillary thermotherapy of small choroidal melanomas is usually followed by early tumor shrinkage but is complicated by dense scotomas, nerve fiber bundle defects, and occasionally macular abnormalities. Short-term follow-up suggests that TTT may arrest growth of selected small melanomas.  (+info)

The malignant choroidal melanoma, in contrast, appears as a mottled, often significantly elevated lesion, ranging in coloration from white to greenish-gray. As it grows, it may break through Bruchs membrane, taking on a mushroom-like appearance. Serous retinal detachments are commonly associated with this presentation. You may also observe overlying orange pigmentation known as lipofuscin. Most malignant melanomas are over 10 DD in size at the time of diagnosis. Most patients with choroidal melanomas are asymptomatic. However, should a significantly large lesion occur in proximity to the macula, the patient may present with metamorphopsia, acuity loss, visual field deficit and/or a hyperopic refractive shift ...

Choroidal melanoma is the most frequently occurring intraocular tumor in adults. The aim of this work is to assess the potential of state-of-the art in-vivo and ex-vivo imaging modalities for the characterization of choroidal melanoma. Multimodal imaging of a choroidal melanoma was performed in a 53-year-old male patient. In-vivo ophthalmoscopy, ultrasound microscopy, duplex ultrasound, and 7.0 T MRI were performed. Ex-vivo examination of the enucleated eye included 7.0 and 9.4 T magnetic resonance microscopy as well as histopathology with hematoxylin and eosin staining. Imaging of choroidal melanoma with ultrahigh field MRI and duplex sonography provides detailed morphologic and functional information of the eye. High-spatial-resolution MRI at 9.4 T shows details of the internal texture of melanoma and other structures of the eye with an in-plane spatial resolution of 32 μm. Ultrahigh field in-vivo MRI at 7.0 T and ex-vivo MRI at 7.0 and 9.4 T correlate well with histologic evaluation. In-vivo ...

Granulomatosis with Polyangiitis Presenting as a Choroidal TumorGranulomatosis with Polyangiitis Presenting as a Choroidal Tumor
Granulomatosis with polyangiitis (GPA) sometimes involves the eye orbit; however, choroidal involvements in GPA had been rarely reported. We report a rare case presenting with a choroidal mass in an 83-year-old Japanese woman who presented with left eye pain. Diagnostic biopsy revealed necrotizing vasculitis with infiltrates of inflammatory cells. Diagnosis was localized granulomatosis with polyangiitis. Combined treatments with corticosteroid plus azathioprine resolved the choroidal mass region. Although treatment with corticosteroid and immunosuppressive agents improves the prognosis of the disease, ocular morbidity is still well recognized. Clinicians should consider a differential diagnosis of GPA in patients with inflammatory choroidal tumors.

Endoresection for choroidal melanoma: palliative or curative intent? | British Journal of OphthalmologyEndoresection for choroidal melanoma: palliative or curative intent? | British Journal of Ophthalmology
There seems to be perpetual controversy surrounding treatment of uveal melanoma since publication of a landmark article by Zimmerman, McLean, and Foster in this journal titled Does enucleation of the eye containing a malignant melanoma prevent or accelerate the dissemination of tumour cells.1 Over the last 30 years, we have come to realise the limitations of the Zimmerman-McLean-Foster hypothesis2 and observed that for comparable-sized tumours, survival is independent of the method of treatment such as plaque radiotherapy, enucleation and proton-beam radiotherapy.3 4 Survival is perhaps similar with trans-scleral resection (TSR), although there are no randomised trials comparing survival following TSR with other methods of treatment.5. These observations imply that distant metastasis of choroidal melanoma, although undetectable at the time of ocular diagnosis by present-day imaging techniques, has perhaps taken place prior to the treatment of primary tumour. This concept is further supported ...

Choroidal Melanoma | Clinical GateChoroidal Melanoma | Clinical Gate
The most common appearance is a pigmented, elevated choroidal lesion that will enlarge without treatment (Fig. 21.2.1 and Fig. 21.2.2). Without documented growth, features such as overlying lipofuscin (orange pigment), associated subretinal fluid, larger size, and proximity to the optic nerve help to differentiate from benign lesions such as choroidal nevus. On a clinical basis, the diagnosis can be made with greater than 99% accuracy. Biopsy is rarely necessary, but can confirm the diagnosis. Radiation retinopathy can often develop after treatment with external radiation (Fig 21.2.3).. ...

Choroidal melanoma is the most common primary tumor of the eye in adults. It is usually a pigmented tumor that grows in the blood-vessel layer (choroid) beneath the retina. Choroidal melanoma has no specific symptoms; it is usually detected during a routine eye examination. If untreated, this cancer can spread to other parts of the body. It is best evaluated and treated by ophthalmologists experienced in this subspecialty.. ...

Retinal Tumours and Pigmented LesionsRetinal Tumours and Pigmented Lesions
With increasing use of indirect ophthalmoscopy and retinal imaging systems it is increasingly common to find pigmented and non-pigmented retinal or choroidal lesions in a routine eye examination. In the vast majority of cases pigmented lesions are benign choroidal naevi, but the alternative; a choroidal melanoma is a life-threatening, potentially-metastatic tumour that can sometimes be difficult to distinguish from a naevus.. Understanding which lesions to refer and which can be monitored is vital in providing good patient care. In this article we will review the prevalence, aetiology, differential diagnosis and treatment of the most common forms of pigmented fundus lesions and ocular tumours and offer advice on management for optometrists.. ...

Enucleation After Iodine-125 Plaque Brachytherapy in Patients with Large Choroidal Melanomas | IOVS | ARVO JournalsEnucleation After Iodine-125 Plaque Brachytherapy in Patients with Large Choroidal Melanomas | IOVS | ARVO Journals
Purpose: Treatment of choroidal melanoma (CMM) with either iodine-125 (I125) plaque brachytherapy or enucleation yields similar survival outcomes. As such, we have used brachytherapy as primary treatment for large CMMs for more than a decade. Herein, we evaluate our cohort of patients with large CMM initially treated with plaque brachytherapy to determine rate of and factors associated with secondary enucleation.. Methods: A retrospective chart review of patients with large CMMs diagnosed and treated at our institution from January 1, 1988 to February 1 2013. Main outcome measures were need for secondary enucleation, local tumor recurrence, all cause mortality, development of metastases, initial apical tumor height and maximal basal diameter.. Results: 245 patients with large CMM were treated primarily with plaque brachytherapy. Local control was achieved in 230 patients (93.8%). Of the 15 patients (6.2%) with local recurrence, 8 underwent secondary enucleation and 7 deferred further treatment. ...

BACKGROUND AND OBJECTIVE To determine whether magnesium sulphate could induce controlled hypotension, reduce choroidal blood flow, provide a dry operative field and could be compared with sodium nitroprusside in the recently raised issue of the use of hypotensive anaesthesia in eye surgery, i.e. for choroidal tumour surgery as the choroid is the most fragile and vascular structure in the eye. METHODS Forty adult patients undergoing choroidal melanoma resection and anaesthetized with 2.5 mg kg(-1) propofol, followed by a constant infusion of 120 microg kg(-1) min(-1), and remifentanil 1 microg kg(-1), followed by a continuous infusion of 0.25 microg kg(-1) min(-1), were randomly assigned to two groups to receive either magnesium sulphate or sodium nitroprusside. RESULTS Controlled hypotension was achieved at the target systolic pressure of 80 mmHg within 107 +/- 16 and 69 +/- 4.4 s for magnesium sulphate and sodium nitroprusside, respectively. Choroidal blood flow decreased by 24 +/- 0.3% and 22 +/

Melanoma arising from the choroid and ciliary body is the most common primary intraocular cancer. The Collaborative Ocular Melanoma Study (COMS) randomized clinical trial of I-125 brachytherapy versus enucleation for medium-sized choroidal melanoma (2.5-10.0 mm in thickness and ≤ 16 mm in diameter) showed that, for patients who met the eligibility criteria, there was no statistically significant difference in all-cause mortality between I-125 brachytherapy and enucleation 5, 10, and 12 years following treatment. The COMS trial supported the use of globe-conserving I-125 brachytherapy. Following brachytherapy, however, visual acuity in the treated eye generally declined at a rate of approximately 2 lines of visual acuity per year and nearly 45% of patients lost ambulatory vision (≤20/200) in the treated eye by 3 years.. Adverse effects of plaque brachytherapy include cataract, radiation-associated proliferative retinopathy, maculopathy and papillopathy. Radiation maculopathy, which may result ...

The decision to treat circumscribed hemangiomas is based on the location, size and related ocular symptoms.4 Shields and coworkers4 reported 200 patients with circumscribed choroidal hemangioma and found that the most common cause for decreased vision was chronic subretinal fluid and chronic macular edema. Optical coherence tomography can be useful in detecting subtle subretinal fluid (Figure 2C) and retinal edema (Figure 2D). Asymptomatic hemangiomas that demonstrate no related subretinal fluid are managed by observation. Hemangiomas with advanced visual deficit and minimal anticipated visual potential can also be observed but it should be understood that progressive subretinal fluid could lead to neovascular glaucoma and ultimate need for enucleation.4 The available treatment modalities are detailed below.. Laser photocoagulation (Xenon or Argon). Laser photocoagulation has been an effective treatment modality for hemangioma for many years. Shields and coworkers4 reported 62% resolution of ...

BACKGROUND: Adenoma of the retinal pigment epithelium (RPE) is a rare intraocular tumor that can simulate other pigmented tumors such as choroidal melanoma. We report a case of non-pigmented adenoma of the RPE initially diagnosed as choroidal hemangioma. CASE REPORT: A 42-year-old woman presented to Kurume University Hospital in November 1992 with an orange-yellow tumor nasal to the optic disc in the left fundus. The tumor was 9.0 × 9.0 mm in diameter, 6.0 mm thick, and was characterized by high intensity on T1-weighted magnetic resonance imaging (MRI), low intensity on T2-weighted MRI, and enhancement on gadolinium MRI. Fluorescein angiography revealed early hypofluorescence and late hyperfluorescence of the tumor and retinal feeder vessels. By April 1996, exudate had developed around the tumor margins. The patient was treated with external beam radiation therapy (20 Gy) in July 1996, but the tumor did not diminish in size. Subsequently, she developed extensive loss of vision due to total ...

In a secondary analysis, we matched 109 PT pts (treated 2010-2011) to the BT pt cohort, using age, sex, tumor height, and distance from tumor to macula as match factors, and analyzed this selected PT cohort separately. Results : Median follow-up for BT, PT and selected PT cohorts were 7.4 years (interquartile range (IQR): 4.8-9.8), 4.3 years (2.0-8.0), and 3.1 years (2.2-3.7), respectively. Median maximum dose to macula for BT, PT and selected PT cohorts were 19 Gy (IQR: 5-53), 52 Gy (0-52), and 52 Gy (0-52), respectively. The prevalence of maculopathy was 4% for PT and 49% for BT. Maximum dose to macula and maculopathy were significantly correlated in the BT NTCP-model, with odds ratio (OR) for 10 Gy increase in dose 1.9 (95% CI: 1.3-2.8). A similar strong dose-response was not found for PT (OR: 1.1, 1.0-1.2). Neither did the comparable PT model show a significant effect (OR: 1.1, 0.8-1.6). Conclusions : Maculopathy rates were different for PT and BT. The NTCP-model for BT showed a ...

Environmental risk factors for uveal melanomas (cancer of the iris, ciliary body and choroid) have not been identified. In order to search for these, we examined the correlation of age-adjusted eye cancer incidence rates, a surrogate for uveal melanoma rates, in U.S. states with group level geographic and demographic factors using multivariate linear regression. Incidence rates for eye cancer were inversely correlated with the percent of the population receiving fluoridated water; i.e., higher rates were found in states with lower prevalences of fluoridation (P = 0.01). Fluoride is known to inhibit the growth of microbial agents that cause choroiditis and choroidal lesions in animals. We speculate that fluoridation protects against choroidal melanoma by inhibiting microbial agents that cause choroiditis and/or choroidal lesions in humans. ...

Magnetic resonante (MRI) showed an apparently choroidal tumour that infiltrated sclera and suggested infiltration of the superior rectus muscle, which would be compatible with a melanoma, which presented differential diagnosis with metastasis or haemangioma. The sonographer reported an elevated hypoechogenic lesion compatible with haemangioma. Fluorescein angiography did not provide us much information, only numerous and marked choroidal folds were evident, with no other alterations of interest in vascularization or parenchyma. Indocyanine green (ICG) did not find alterations to clarify the diagnosis. VA was maintained over the time. Analytical and sistemic imaging tests were normal, so there was no related systemic disease. The size of the lesion was slowly declining ...
