Papulonecrotic tuberculid with spontaneous remission.
We describe a 62-year-old Japanese woman who had skin lesions involving her extremities, chest and back that showed spontaneous remission. The skin lesions consisted of slightly atrophic scars and crusted, reddish or necrotic papules. A tuberculin test showed induration and bulla, which was regarded as strongly positivity. Histopathologically, a tuberculoid granuloma with necrosis was present in the upper dermis and the deep dermis, including the adipose tissues. Bacterial cultures were not positive from sputum, urine or stool, and the chest X-P was also normal. After skin biopsy, all the lesions disappeared within 1 month. No relapse was noted in the entire body.
