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.

Localized cystic degeneration of peripheral arteries represents and unusual cause of arterial insufficiency. It frequently occurs in patient without generalized arteriosclerosis. It has been reported in patients from age 11 to 62 years. Cystic adventitial disease is most common in the popliteal artery. At least 115 cases have been reported worldwide, but none in Korea. We report a case of cystic adventitial disease involving the left popliteal artery. This 64-year-old man presented with an 18-month history of cramping pain of sudden onset in the left calf and claudication. Angiographic findings showed a 6 cm length of luminal obliteration of the popliteal artery. Segmentally resected popliteal artery showed two longitudinally directed cystic masses measuring 3.5x1.5 cm and 2.5x1.5 cm in the adventitia. Microscopic examination revealed cystic space in the arterial adventitia compressing arterial lumen. There were a number of foamy histiocytes collected along the cystic lumen.

A case of pulmonary arteriovenous fistula in a 8-year-old boy who presented with easy fatigability and cyanosis for 4 months, is described. Grossly, there was a large vascular anomaly measuring 2x2 cm in the center of the removed right lower lobe. Microscopically, the lesion consisted of dilated arterial and venous structures resembling a cavernous hemangioma. Subintimal fibrosis and attenuated vascular structure lacking elastic fiber and representing A-V shunt were also noted in the lesion.

Glassy cell carcinoma (GCC) of the uterine cervix is a rare and highly malignant tumor, accounting for only 1%~2% of all cervical carcinomas. It is typically composed of malignant cells having a moderate amount of cytoplasm with "ground glass" appearance, distinct cell membranes that stain with eosin or periodic acid-Schiff, and large nuclei with prominent nucleoli. Since its original description in 1956 by Glucletmann and Cherry, 200 - 250 cases of GCC of the uterine cervix have been listed in the literature. We report here the clinicopathological study of one case of glassy cell carcinoma with brief review of the literature.

Alveolar soft-part sarcoma of the female genital tract are extremely rare. Fewer than 30 cases have been described in the literature. We experienced a case of alveolar soft-part sarcoma of the female genital tract which was diagnosed by routine light microscopic study using ultrastructural and immunohistochemical stain. We report this case with a brief review of the literature.
