Case for diagnosis. Noninfectious suppurative panniculitis induced by mesotherapy with deoxycholate

Abstract A 28-year-old white female patient presented with multiple erythematous-to-violaceous, painful, suppurative nodules on the buttocks and thighs that appeared after two weeks of mesotherapy with deoxycholate, caffeine, sunflower liposomes, and sinetrol for localized fat. She was treated for atypical mycobacteriosis, but with no satisfactory response after antibiotic therapy. Bacterial, mycobacterial, and fungal culture were all negative. Histopathologic examination of the biopsy showed noninfectious suppurative panniculitis. It resolved after treatment with methotrexate, prednisone, and hydroxychloroquine. This report highlights the rarity of this complication, the importance of its early recognition, and differentiation with atypical fast growing mycobacterioses.

Dapsone dependent nodular panniculitis.

A patient recorded to be suffering from tuberculoid leprosy since 1973 and on regular Dapsone monotherapy for about nine years developed asymmetrical, erythematous, subcutaneous, nodular swellings restricted chiefly to the extensor aspects of lower limbs two months after discontinuation of Dapsone therapy. During the course of Dapsone treatment, the patient had developed similar swellings twice previously each time when he stopped the drug for about a month. The swellings disappeared on commencement of Dapsone Treatment. This has been reconfirmed under our supervision. The biopsy of one of the lesions revealed panniculitis with vasculitis. The original diagnosis of leprosy was probably invalid.
