Fibrous histiocytoma of the corneoscleral limbus and conjunctiva.

An 11-year-old boy and a 28-year-old woman each had a painless, slowly enlarging, elevated, yellow lesion of the inferior corneoscleral limbus and adjacent cornea and conjunctiva of the left eye. Histopathologic examination of both lesions disclosed involvement of the conjunctival substantia propria and the adjacent limbal and peripheral corneal stroma by a nonencapsulated, dense infiltrate composed of elongated fibrocytic cells, plump histiocytic cells occasionally with a vacuolated cytoplasm, some multinucleated giant cells, and scattered lymphocytes. The diagnosis in each case was fibrous histiocytoma. Both patients were otherwise in good health with no dermatologic, systemic, or other ocular abnormalities.

Inferior oblique myositis presenting as superior oblique muscle palsy.

A 14-year-old girl presented with progressive vertical strabismus simulating superior oblique muscle palsy. However, because of the presence of limitation of infraduction, computed tomography was done; it showed a large mass in the region of the right inferior oblique muscle. A biopsy specimen of the enlarged muscle showed mainly degenerative and some regenerative changes. The diagnosis was orbital myositis, which should be considered in the differential diagnosis of strabismus, especially if the clinical findings are atypical of strabismus.

S-antigen immunoreactivity in trilateral retinoblastoma.

Using monoclonal antibody MAbA9-C6, which identifies an antigenic determinant of S-antigen retained in fixed tissue sections, we investigated S-antigen immunoreactivity in the ocular and brain tumors of four cases of trilateral retinoblastoma. In the eye, S-antigen immunoreactivity was present in all retinoblastomas examined, as well as one retinocytoma characterized by benign appearing cells including fleurettes. S-antigen immunoreactivity was focally present in two of the four brain tumors examined. Additionally, two intraocular medulloepitheliomas, one of which contained well-defined rosettes, and 16 primary intracranial tumors, including seven pineal gland tumors and nine other lesions, some of which histopathologically may resemble retinoblastoma, were examined. S-antigen immunoreactivity was observed in two pineal gland tumors but not the remaining nine primary intracranial neoplasms or the two intraocular medulloepitheliomas. Our results further substantiate the immunologic relationship between the retina and the pineal gland, and tumors originating in these tissues.

Keratoconus with spontaneous perforation of the cornea.

A 24-year-old woman with a 5-year history of bilateral keratoconus who was in her eighth month of pregnancy presented with central corneal edema and mild acute iritis in her right eye. The iritis responded rapidly to therapy with topical corticosteroids, which was stopped after 1 week. The patient returned 1 week later with a markedly edematous central cornea, which had perforated. Management included a therapeutic soft contact lens, patching and, eventually, penetrating keratoplasty. The authors discuss the possible role of the pregnancy and of the topical corticosteroids in the development of the corneal perforation, a rare complication of keratoconus.

[Hypophyseal tuberculosis. A case report].

The authors present a case of hypophyseal tuberculosis. It is the case of a patient with abnormal sella turcica, erosion of sella and hypopituitarism. At intervention, they ascertain a lesion of sphenoïdal sinus with the lesion of hypophysis. The authors made the review of literature and ascertain the singularity of the both lesion. Generally, the tuberculosis of adenohypophysis is associated with tuberculosis meningitis. They think that it is an extension of sinusal lesion.
