These patients had no context of immunosuppression, no history of diabetes, renal failure, or long-term treatment with corticosteroids or immunosuppressants, and no evidence for a neoplasia. HIV serology and viral hepatitis were negative; the electrophoresis of proteins showed an inflammatory profile. The management of these patients required prolonged anti-tubercular therapy over a period of nine months based on 2 months of Ethambutol (20 mg/kg/24 h), Rifampicin (10 mg/kg/24 h), Isoniazid (5 mg/kg/24 h) and Pyrazinamide (25 mg/kg/24 h), then 7 months of Rifampicin (10 mg/kg/24 h) and Isoniazid (5 mg/kg/24 h). A surgical drainage was indicated in 2 cases. Three patients were declared cured with a decline of 40 months; 3 others are still under treatment with complete healing of skin lesions, and 1 patient was lost from sight.
