ABSTRACT Cutaneous tuberculosis accounts for 2% of all extrapulmonary tuberculosis and is one of the multiple clinical presentations of extrapulmonary tuberculosis. We report a case of cutaneous tuberculosis with unusual clinical and histological presentations. CASE REPORT: We report the case of a 29-year-old woman with plurifocal tuberculous lupus. Histological examination of cutaneous lesions revealed the presence of a granuloma with caseum necrosis. Chest X-ray showed a severe pulmonary tuberculosis lesion. The Mantoux test performed by intradermal injection was positive. Skin lesion PCR and sputum culture were negative. Both skin and pulmonary lesions responded to antituberculous treatment. COMMENTARY: Lupus vulgaris is commonly presents on the head and neck. The diagnosis may be difficult when lupus vulgaris occurs at unexpected sites or in unusual clinical presentations. Caseum necrosis observed in our patient was unusual.

    ABSTRACT: Tuberculosis is endemic in Tunisia. Pulmonary tuberculosis is the most common presentation in our country. Cutaneous presentations are rare (1-2% of cases). The diagnosis of cutaneous tuberculosis (CT) is difficult. Histological and clinical presentations are polymorphous, many differential diagnoses are available, and it is difficult to isolate Mycobacterium. We had for aim to study the epidemiological and clinical features of CT in Tunisia, and to compare presentations before and after 1990. We conducted a retrospective study between January 1991 and December 2011, in which we included all cases of CT observed at the Infectious Diseases and Dermatology Units of the Tunis la Rabta Hospital. Hundred and thirty-seven patients were included, with a mean age of 43.8years; 72.3% were female patients. Hundred and fifty locations were observed, most of which on the head and neck. Scrofuloderma was the most frequent presentation, observed in 65% of cases. The diagnosis was confirmed by histology and/or microbiology in 75.8% of cases. The treatment was prescribed for a mean 11.3months, leading to full recovery in most cases. CT is still reported in Tunisia. The diagnosis relies mainly on histology. Controlling this mutilating tuberculosis requires a global control of this disease, and especially lymph node location, given the high rate of scrofuloderma.
