ABSTRACT
Nevus sebaceus of Jadassohn is a hamartoma of the skin with the potential to develop benign and malignant neoplasms. This case was characterixed by multiple basal cell epitheliomas, clinically one reddish nodule and multiple pigmented papules, arising in the nevus sebaceus. Histologically, epithelial papillomatous hyperplasia and high-positioned hyperplastic sebaceous glands were found, and tumor nests consisting of basaloid cells with peripheral palisading arrangements were mainly situated in the upper dermis without significant infiltrative growth. We report a rare case of nevus sebaceus with multiple basal cell epitheliomas in the right cheek of a 49-year-old woman.

Scrofuloderrna results from a direct extension of an underlying tuberculous focus such as the lymph nodes, bone or joint to he overlying skin, and is often associated with pulmonary tuberculosis. A 59-year-old male pai ient presented with an asymptomatic, flesh colored, 0.8 x 1.0 cm sized, solitary nodule on the left, middle back area. He had a CT-guided percutaneous lung biopsy 3 weeks before, for the evaluation of a round focal inhomogenous mass in the left lower lung field on radiologic study. An cxcisional biopsy specimen from the skin lesion showed granulomatous infiltration, composed of pithelioid cells, mononuclear cells and Langhans giant cells in the deep dermis and the suhcutaruous fat layer. Caseation necrosis within the tubercles was marked and numerous acid-fast bacilli were identified on AFB staining. Here we report an unusual case of scrofuloderma occurring after a percutaneous lung biopsy.
