Multiple Pyogenic Granulomas in Port-wine Stain after Laser Therapy / 대한피부과학회지

Pyogenic granuloma (PG) and port-wine stain (PWS) are vascular lesions that rarely occur in association. While PWSs are congenital capillary vascular malformations, PGs are acquired benign vascular proliferations. Although the pathogenesis of PG is unknown, many authors feel that they represent reactive hyperplasias, especially as they are often seen in response to trauma. We report the multiple pyogenic granulomas developed in a port-wine stain following Nd-YAG laser therapy.

A Case of Nevoid Basal Cell Carcinoma Syndrome with Multiple, Symmetrically Distributed Basal Cell Carcinomas / 대한피부과학회지

Nevoid basal cell carcinoma syndrome is a rare inherited disorder characterized by multiple cutaneous basal cell carcinoma, pits of the palms and soles, cysts of the jaws, and ectopic calcification of cranial membranes. The patient was a 66 year old female. She complained of multiple, symmetrically distributed black-colored papules on the both sides of the neck. On physical examination, multiple pits were detected in the palms and soles. The histopathologic findings of the papules showed variable shaped and sized tumor nests composed of basaloma cells. On PNS CT for search of metastasis of the cancer, odontogenic keratocyst was detected at the Lt. alveolar process of maxilla by accident. We diagnosed her nevoid basal cell carcinoma syndrome and the lesions on both sides of the neck were removed completely.
