Lupus vulgaris on the buttock mimicking tinea corporis

Lupus vulgaris is the most common form of cutaneous tuberculosis which usually occurs in patients previously sensitized to mycobacterium tuberculosis. It is often clinically and histopathologically confused with various cutaneous disorders. Here, we present a 28-year-old man attended in our medical college with slowly progressive, asymptomatic, annular erythematous skin lesions on the buttocks for 8 years. He consulted with many physicians and was improperly treated with an oral antifungal agent for several months under the diagnosis of tinea corporis, but no cure was observed. A diagnosis of lupus vulgaris was made based on the histopathological examination and the polymerase chain reaction. Anti-tuberculosis therapy was administered and the lesions started to regress

case report of chronic sclerosing panniculitis

Sclerosing panniculitis is a fibrotic process that usually occurs on the legs, commonly in women older than 40. The principal features are indurated woody plaques with erythema, edema, telangiectasia, and hyperpigmentation. Although the exact pathogenesis is uncertain, it is thought to occur as a result of ischemic changes. We present a 28-year-old married female who had a 10-year history of painful sclerotic plaques, repeated ulceration and healing with fibrosis of the both lower legs and abdomen. Venogram and Doppler investigations were normal. Skin biopsy from the edge of the ulcer demonstrated the feature of chronic sclerosing panniculitis. Satisfactory improvement was found with methotrexate 7.5mg weekly for 4 months. No recurrence was noted within 1 year follow up
