Primary cutaneous anaplastic large cell lymphoma initially clinically considered to be pyoderma gangrenosum

Primary CD30+ anaplastic large cell lymphoma, which is generally seen in adults, is the second most common cutaneous T-cell lymphoma after mycosis fungoides. The lesions are characterized by red-brown plaque or nodules often with ulceration. Although usually solitary, there may occasionally be multiple lesions. Here in this case report, a 44-year old male patient with multifocal primary cutaneous anaplastic large cell lymphoma is presented. Primary cutaneous anaplastic large cell lymphoma is a rare disease especially when it is multifocal and has no systemic involvement like in this case. Therefore this case is found valuable to share.
