A Case of Ossifying Fibromyxoma of the Neck / 대한피부과학회지

An ossifying fibromyxoma is a benign neoplasm which usually presents in soft tissue. It is a rare tumor of uncertain differentiation which virtually always acts in a clinically-benign fashion. Most patients present with a small, painless, well-defined, often lobulated subcutaneous mass, which affects the extremities, or less commonly the trunk, head and neck, and mediastinum. Its typical microscopic appearance is that of lobulated nests of uniform, round-to-oval shaped cells, separated by fibromyxoid stroma, in which an incomplete marginal shell of mature bone can be seen. We herein report the first case of an ossifying fibromyxoid tumor of the neck in Korea.

A Case of Clear Cell Acanthoma on the Dorsal Foot / 대한피부과학회지

Clear cell acanthoma is a rare, benign tumor of epidermal origin, with distinct histolopathological features which usually includes solitary or rarely multiple tumors, often localized on the lower legs of middle-aged or elderly people. It presents as a flat or dome-shaped, sharply-demarcated papule or nodule, sometimes with a keratotic scale of bright red or pink color. Histopathological findings include clear cells within sharply-demarcated area of the epidermis. We report a case of clear cell acanthoma which developed on the lateral side of the right foot of an 82-year-old man.

A Case of Eccrine Poroma on the Scalp / 대한피부과학회지

Eccrine poroma is a benign neoplasm, whicn is thought to originate from the eccrine sweat gland. Previous studies suggest that these are primarily lesions of the hairless acral surface. We report a clinicopathological case of a 30-year-old man who presented with a 2.0 by 1.2 cm sized, unusual scalp lesion, which proved to be an eccrine poroma. There has been no local recurrence in the 4 months since complete excision.
