Adenoma of Retinal Pigment Epithelium: A case report.: Jae Soo Koh, Je G Chi; Korean J Pathol. 1996;30(11):1053-1056.

Abstract PDF: A retinal pigment epithelium tumor is extremely rare, and the distinction from malignant melanoma or reactive hyperplasia of pigment epithelium is mandatory, clinically or pathologically. We report a case of adenoma of retinal pigment epithelium. A 21 year-old female presented with a sudden decrease of visual acuity. She had no previous inflammatory ocular disease. Fundic examination revealed an elevated mass at the temporal side of the right eye. With the suspicion of choroidal malignant melanoma, a right eye enucleation was done. Grossly there was a 0.7x0.5 cm dark soft broad-based elevated lesion in the temporal side. The anterior border was the ora serrata, and the posterior border reached the equatorial area. The tumor was confined to the intraocular portion. Histologically, the tumor mass was composed of the cuboidal or columnar cells arranged in papillary, trabecular, or solid pattern with fine fibrovascular stroma. The tumor cells were heavily pigmented. The cytoplasmic border of the tumor cell was indistinct and there was a finely granular brown pigment diffusely scattered in the cytoplasm. Mild anisokaryosis noted, but hyperchromatism or pleomorphism were negligible. The nucleoli were small. A transition between normal retinal pigment epithelium and tumor mass was noted. Reactive gliosis was noted at the periphery of the tumor.

Papillary Adenocarcinoma of Nonpigmented Ciliary Epithelium of the Eye.: Hyun Joo Choi, Yeong Jin Choi, Youn Soo Lee, Eun Jung Lee, Seok Jin Kang, Byung Kee Kim, Sang In Shim; Korean J Pathol. 1998;32(12):1104-1107.

Abstract: Adenocarcinoma of the ciliary epithelium is a rare tumor, usually occuring in elderly patients who have a history of severe ocular trauma or chronic inflammation. We report an adenocarcinoma of the nonpigmented ciliary epithelium found within the phthisical globe of a 36-year-old female whose eye had been loss of vision since infancy. The mass, measured 4.0 x 4.0 cm, was relatively limited by sclera but had invasion to posterior portion. Histologically, the tumor was a compact mass which consisted of tubular and papillary structures with foci of the pleomorphic area. Strands of cells and individual cells were invested with thick basement membrane that have positivity for periodic acid-Schiff stain. Immunohistochemical staining showed strong reactivity for cytokeratin and epithelial membrane antigen, and focal for neuron-specific enolase and S-100 protein.

Intraocular Ossification: A Case Report.: Ho Sung Park, Tae Shik Kong, Kyu Yun Jang, Myoung Ja Chung, Woo Sung Moon, Dong Geun Lee, Myoung Jae Kang; Korean J Pathol. 2004;38(3):188-190.

Abstract PDF: Heterotopic bone formation in the eyeball is a rare finding. Some etiologic factors, such as trauma, chronic inflammation, and long-standing retinal detachment have been associated with the onset of intraocular ossification. We report here on a case of a 21-year-old woman with a history of blunt trauma fifteen years ago, who complained of right eye blindness. When the right eyeball eviceration was done, a hard, grayish mass was found. On histopathologic examination, the mass showed lamellar bone with fatty marrow and hyalinized tissue with dystrophic calcification. We diagnosed her case as intraocular ossification.

A Histopathological Analysis on 73 Cases of Enucleated Eyeballs.: Kyoung Chan Choi, Joon Hyuk Choi, Won Hee Choi, Tae Sook Lee, Myung Mi Kim; Korean J Pathol. 1994;28(5):460-468.

Abstract PDF: A total of 73 enucleated eyeballs is reviewed and analyzed clinicopthologically. These eyeballs were selected among the enucleated spceimens that had been removed at the Yeungnam University Hospital during a period of 10 years beginning from 1983 to 1992. Following results were obtained. 1) When the eyeballs were classified according to me direct cause of removal, the neoplasm was the most common single cause accounting for 26 cases(35.6%) out of 73 cases, followed by phthisis bulbi l6 cases(21.9%), trauma 10 cases(13.7%), glaucoma 8 cases(10.9%), inflammation 5 cases(6.8%), staphyloma 4 cases(5.5%), retinal detachment 1 cases(1.4%), Coat's disease 1 cases(1.4%), corneal disease 1 cases(1.4%) and choroidal hemorrhage 1 cases(1.4%). 2) 39 cases(53.4%) were male and 34(46.6%) were female. 23 cases(31.5%) were below 10 years of age, which was the highest rate. 3) The neoplastic lesion included retinoblastoma 20 cases(76.9%) in 26 neoplasms, malignant melanoma 4 cases(15.3%), hemagioblastoma of optic disc 1 cases(3.9%), adenocarcinoma of Meibomian gland 1 cases(3.9%). 4) Retinoblastoma was the commonest intraocular tumor accounting for 20 out of 26 cases, In growth pattern, 80.0% of the tumor grew endophtytically. True rosette were seen 60% of the retinoblastoma.

Case Report

Sebaceous Adenoma in Medial Caruncle of the Eye: A case report.: Geon Kook Lee, Joong Seok Seo, Kye Yong Song, Je G Chi; Korean J Pathol. 1991;25(2):174-177.

Abstract PDF: Sebaceous adenoma is a rare solitary or multiple yellow, circumscribed neoplasm consisting of sharply demarcated, proliferating lobules or irregular size and shape that are composed of three cell bypes: basal cells, mature and transitional sebaceous cells. We reported a case of extremely rare sebaceous adenoma arising in caruncle of the left eye in a 78-year-old female. A polypoid tumor nodule, measuring 0.6x0.5 cm, was noticed 6 months before resection. It was grayish white with granular surface. There is no evidence of associated visceral neoplasm. Histopathologically, it revealed a lobulated tumor, composed of equal amount of highly differentiated sebaceous and intermediate transitional epithelium with minor participation of basaloid cells. This tumor is thought to be the neoplasm of the sebaceous gland normaly present in the caruncle of the eye rather than ectopic origin.

Sebaceous Carcinoma of the Eye Lid.: Hye Kyung Ahn, Gui Ok Yoon, Ill Hyang Ko; Korean J Pathol. 1989;23(3):387-391.

Abstract PDF: Sebaceous carcinoma is uncommon and usually presents in the ocular adnexa as a cancer of the meibomian glands. They are frequently mistaken for chalazion. Considerable time often elapses before a diagnosis is made. We present a case of sebaceous carcinoma of the left eye lid in 59 year old female who had a history of 3 repeated surgical resections clinically diagnosed as chalazion during last 3 years.

Case Report

A Case of Ocular Neurofibromatosis.: Je G Chi, In Ae Park; Korean J Pathol. 1987;21(1):62-65.

Abstract PDF: Neurofibromatosis is one of the neurocristopathies that involve many system or tissues forming various types of lesion. Almost every tissue or organ can be involved by this disease. However, the eyeball itself is very rarely affected by this process. The findings seen in our case indicate the diversity of lesions in neurofibromatosis, and also suggest hamartomatous nature. Heterotopic ganglion cells and glial cells in uveal tract are not easily understood. We reported here a case of intra-occular neurofibromatosis with its characteristic involvement of the uveal tract, in a 21 year old female. Her ocular symptoms began at her age of 11 as poor vision and were slowly progressive together with multiple facial neurofibromas. The involved left eyeball showed many ganglioneuroglial cell nests in iris, ciliary body and retina. Minute plexiform neurofibromas were also seen in small nerve twigs around the eyeball.
