Iris melanoma is a malignant melanocytic tumor, making up 1.2%-6.6% of uveal malignant melanomas. The growth of choroidal melanoma during pregnancy is described and a hormonal influence is suggested. We present a case of iris melanoma occurring during pregnancy. A 32-year-old woman, in the 28(th) week of her fifth pregnancy, was referred to the ophthalmologist with a 2-month history of blurred vision and pain in her left eye. The visual symptoms became progressively worse with decreasing vision. Her visual acuity was 20/70 in her left eye, with a temporal, pigmented, prominent iris mass extending into the trabecular meshwork and the corneal endothelium. Elsewhere other pigmented localizations were found in the iris and in the trabecular meshwork. There was secondary glaucoma with intraocular pressure of 36mmHg and C/D=0.9. The right eye was normal. A general physical examination found no pigmented lesions. Chest radiography and hepatic ultrasonography revealed no metastasis. The diagnosis of iris malignant melanoma was made from the diffuse involvement extending into the trabecular meshwork and the advanced secondary glaucoma; an enucleation was performed and histopathological examination confirmed the diagnosis of iris melanoma with involvement of the trabecular meshwork. The patient had no further problems (follow-up of 11 months). From this case report, we discuss the differential diagnosis of iris melanoma and the hormonal influence on its growth.

We report a case of an unusual clinical presentation of posterior scleritis. A 40-year-old woman suffered from sudden blurred vision in her left eye for 1 day. She had no systemic or autoimmune diseases. Fundus examination revealed a subretinal mass (10.5 x 6 mm in basal diameter) in the nasal-superior quadrant extending from the optic disc to the periphery. Overlying retinal striae were obvious. Optic disc hyperemia and mild edema were noted. Fluorescein angiography did not show dye leakage or tumor-feeding vessels. Ultrasonography showed high internal reflectivity of the subretinal mass and thickened sclera with T-sign. Under the impression of posterior scleritis, corticosteroids and nonsteroidal anti-inflammatory drugs were given orally and topically. After 4 weeks, the subretinal mass disappeared without any sequelae. The patient recovered full vision. This case suggests that posterior scleritis is among the differential diagnoses for a fundus mass. There has been no other similar report in Taiwan.

The authors describe the case of a 38-year-old man with progressive headache and blurred vision related to a hemangiopericytoma located exclusively in the confluence of sinuses (CoS) and in the transverse sinuses bilaterally. They believe this is the first report in which a hemangiopericytoma of the dural sinuses has been described without any intradural component. Although the diagnosis was not suspected preoperatively, a gross-total resection of the tumor with restoration of sinus patency was achieved to relieve the symptoms. This diagnosis should be included in the preoperative differential diagnosis of a tumor of the CoS. Successful resection can be achieved in these cases.

A 76-year-old man presented with leukostasis syndrome, including oculodynia, blurred vision, and visual field defects, due to mantle cell lymphoma, prolymphocytoid variant, with marked leukocytosis, 1227 x 10(9)/l. He had splenomegaly but no lymphadenopathy or hepatomegaly. The tumor cells were CD5+, CD19+, CD20+, FMC-7+, and kappa light chain restricted. Immunohistochemistry showed expression of p53 and of cyclin D1. Fluorescent in situ hybridization demonstrated t(11;14) with translocation between CYCLIN D1 and the immunoglobulin heavy-chain genes. The patient received leukapheresis and aggressive chemotherapy, but the leukocyte count remained above 100 x 10(9)/l. The patient's condition rapidly deteriorated with lymphomatous infiltration of his lungs and soft tissues, and he expired 6 months after diagnosis. While it is known that mantle cell lymphoma may have a leukemic phase, the degree of leukocytosis in this case exceeds that previously reported in the literature and resulted in a clinical syndrome of leukostasis.

Visual improvement following octreotide for growth hormone secreting pituitary macroadenomas is uncommon without tumour shrinkage. A 45-year old lady presented with blurred vision for 12 months. Visual assessment revealed a bitemporal hemianopia and CT scan demonstrated a large pituitary tumour with lateral and suprasellar extension. Acromegaly was confirmed by 75 g glucose tolerance testing. Primary transsphenoidal surgery was performed with normalisation of visual acuity and fields of vision. Post-operatively she had anterior pituitary hormone deficiency. As GH and IGF-1 levels remained elevated she underwent external pituitary irradiation. CT scanning demonstrated tumour shrinkage associated with a modest fall in GH levels. IGF-1 levels remained elevated falling to the age-related upper limit of normal after 5 years. At regular review she had stable visual acuity and fields of vision. She presented as an emergency 7 years from presentation with reduced vision and recurrence of bitemporal hemianopia. An MRI demonstrated a large pituitary adenoma. We therefore undertook a carefully monitored trial of octreotide with great caution with daily reassessment of acuity and fields. A decision was made to proceed to surgery in the event of deterioration or lack of improvement after a short trial over 5-7 days. We observed normalisation of visual acuity and perimetry within 3 days. She then commenced long-acting octreotide (Sandostatin LAR) 20 mg every 28 days. MRI after 1 week showed shrinkage of the tumour by a few millimetres. Five months later repeat MRI failed to show any further improvement in tumour size. However she remains well 29 months from treatment with normal vision and is being monitored carefully as her chosen form of therapy. Somatostatin analogues may be effective as therapy in a selected group of patients with acromegaly and visual loss who are not suitable for pituitary surgery. If used in this way the drug must be given cautiously with frequent detailed ongoing visual assessments. In this present case there has been a restoration of vision but the long-term outlook remains guarded without significant tumor shrinkage.

Primary non-Hodgkin lymphoma (NHL) of the nasal cavity is a rare neoplasm. They account for about 0.17-2% of all cases of NHL and 5.8% of all malignant neoplasms of the sinonasal region in adults. A 37-year-old male patient presented with left-sided nasal obstruction and headache which appeared a couple of weeks before the admission. Nasal examination revealed a massive polyposis. After medical therapy with corticosteroids, neither the polyposis nor his complaints showed regression; thus, he underwent a nasal polypectomy operation. Biopsy results indicated an inflammatory nasal polyp. Two weeks later, a rapidly progressive facial swelling, especially in the left periorbital area and blurred vision occurred. Second biopsy, which was also taken from the left nasal cavity suggested again an inflammatory nasal polyp. To rule out any possible malignancy, a third biopsy was conducted in the left maxillary sinus which indicated T/NK cell lymphoma of the sinonasal tract.

Ancient change in a schwannoma is a histological variant typically found in longstanding tumors. Histologically, the tumor has biphasic features typical of a schwannoma with evidence of degenerative changes that may complicate diagnosis. The authors report on a 23-year-old man with no features of neurofibromatosis who presented with headaches, blurred vision, and ataxic gait. Magnetic resonance imaging demonstrated a rim-enhancing lesion in the cerebellopontine angle with displacement of brainstem structures and no supratentorial hydrocephalus. Using a lateral suboccipital approach together with image guidance and intraoperative neurophysiological monitoring, a gross-total macroscopic excision was performed. At surgery, the tumor was found to arise from the inferior division of the trigeminal nerve. The final histological diagnosis was schwannoma with ancient change. Note that ancient change in schwannomas is a histological variant thought to result from degenerative changes in longstanding tumors. To the authors' knowledge, this is the first independent report of this histological variant in an intracranial schwannoma.

Reported herein is a case of 62-year-old man who complained of blurred vision and ocular pain in his right eye. The patient was diagnosed with choroidal melanoma complicated by neovascular glaucoma (NVG) and total retinal detachment, and he underwent enucleation of the eye. The isolated tumor was 2.5 x 2.5 cm in size. It was accompanied by intratumoral calcification, and consisted of epithelioid and spindle melanoma cells. There were a variety of microvessels in the stroma of the iris. The expression of thymidine phosphorylase (dThdPase), an angiogenic factor, was examined immunohistochemically. Cytoplasmic immunoreactivity for dThdPase was more prominent in the epithelioid cells than in spindle tumor cells. Another case of choroidal melanoma without NVG had less marked immunoreactivity. These results suggest that the production of dThdPase by melanoma cells correlates with the pathogenesis of NVG.

Intracranial granulocytic sarcoma (chloroma) may occur rarely in leukemia. A 27-year-old male presented with an isolated recurrence of granulocytic sarcoma manifesting as an intraaxial mass 27 months after complete remission of acute lymphoblastic leukemia. He was admitted due to a severe headache and blurred vision. Brain magnetic resonance imaging demonstrated an enhanced mass which was initially interpreted as an extraaxial tumor in the right temporal region. Because of increased intracranial pressure and the mass effect, open biopsy with surgical resection was performed. The biopsy result indicated that intraaxial lymphoblastic leukemia infiltration had caused CNS relapse. Although granulocytic sarcoma occurs primarily in patients with acute myelogenous leukemia, the authors report a rare case of intraparenchymal granulocytic sarcoma in acute lymphoblastic leukemia.
