Lichen scrofulosorum - A series of eight cases

Lichen scrofulosorum is a rare entity of children and young adults. The cut aneous lesions are typically symptomless papular eruptions, associated with a strong Mantoux reaction, tuberculosis of lymph nodes and/or other organs . Eight patients between the ages of 5 and 36 years were included in this s eries. Lesions were commonly seen on the trunk, though a case of involvemen t of the palms and soles was also observed. Pulmonary tuberculosis was seen in 5 adults; 1 patient each had pleural effusion, tuberculous adenitis and tuberculoma, respectively. Histopathological examination typically showed epithelioid cell granulomas around hair follicles. The histogenesis is uncl ear, a type IV hypersensitivity reaction provoked by chronic tubercular inf ection is probable. The patients responded well to antituberculous therapy. Copyright (C) 2000 S.
