TY - JOUR TI - Unrecognized lupus vulgaris, revealed by its treatment AU - Baali, Nadia AU - Ismail, Aymane AU - Hocar, Ouafa T2 - Our Dermatology Online AB - A 49-year-old woman, without medical or family history, presents since 6 months ago an erythematous-squamous, papular plaque at the centro-facial level that increased very progressively. The physical examination was normal including pleuropulmonary, abdominal and osteo-articular examination. Everything was evolving in a context of apyrexia and conservation of the general state. During her hospitalization, the cutaneous biopsy found a granuloma with epitheliod and giant cells without caseous necrosis. The tuberculin IDR was negative. The search of Koch bacillus was negative in the cutaneous samples and sputum. TPHA/VDRL and HIV serologies were normal. The bacteriological and mycological examination of the biopsy fragment was negative. The expert gene to identify Mycobacterium tuberculosis was negative and also the smears to research leishmania bodies were negative. Despite the absence of diagnosis evidence, an anti-tuberculosis treatment; 2RHZE/4RH regimen, was prescribed and a spectacular amelioration was noted during and many months after the end of the treatment. So, the response to the treatment was the only diagnosis evidence for the lupus vulgaris.
