Case Report

Generalised perforating granuloma annulare mimicking papulonecrotic tuberculid

JTHT Yu 余浩德 and KC Lee 李景中

Abstract
A 45-year-old man presented with a six year history of erythematous umbilicated papules on trunk and limbs. An initial diagnosis of papulonecrotic tuberculid was made but he did not respond to anti-tuberculosis chemotherapy. Finally, the diagnosis of perforating granuloma annulare was reached after the fourth skin biopsy. He was successfully treated with topical steroid.
