Cutaneous CD30 positive anaplastic large cell lymphoma

An adult Caucasian male presented with a solitary abscess-like lesion on his left thigh. The lesion later on ulcerated and developed a central eschar. The initial differential diagnoses included deep mycosis, insect bite reaction or atypical mycobacterial infection. Histology confirmed it to be a CD30 positive anaplastic large cell lymphoma. Haematologyoncology screen was carried out and the patient started on local field radiotherapy. Localized lymphomatous lesions can be treated with surgical excision or local radiotherapy. Systemic treatments are reserved for generalized disease. The prognosis depends on the extent of involvement.
