Abstract

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.
