CROWN ON HEAD - A DIAGNOSTIC CHALLENGE

Abstract : Lupus vulgaris is a chronic progressive post primary, pauci bacillary form of cutaneous tuberculosis with moderate or high immunity. Atypical clinical presentations depend on host immunity and leads to difficulty in diagnosis and treatment. A 55year old male with skin lesions over the scalp diagnosed as Granuloma annulare was treated with topical steroids , not responded to therapy and later developed a plaque over the left cheek involving the ala nasi of nose which mimicked basal cell carcinoma. But on biopsy it was found to be lupus vulgaris. This case is presented for atypical manifestation of lupus vulgaris mimicking Granuloma annulare, probably the first case report to our knowledge.
