Co-existence of atypical tuberculid with lupus vulgaris.

ABSTRACT

Cutaneous tuberculosis (CTB) is an uncommon form of extra-pulmonary tuberculosis accounting for ≤2% of mycobacterium tuberculosis cases and is more often reported from developing countries. Tuberculid, a cutaneous hypersensitivity reaction to mycobacteria or its fragments, is a another rare cutaneous manifestation seen in association with tuberculosis of other organ systems including tuberculous lymphadenitis, pulmonary tuberculosis, etc. Co-occurrence of a tuberculid with CTB is extremely rare. Herein we report a childhood case of lupus vulgaris, a type of CTB, associated with an atypical presentation of tuberculid.
