title: Nasal-type extranodal natural killer/T-cell lymphoma presenting as a solitary non-healing lower leg ulcer.
abstract: Nasal-type extranodal natural killer/T-cell lymphoma (ENTCL) is an aggressive form of non-Hodgkin's lymphoma with a poor prognosis. Primary cutaneous lesions of ENTCL usually present as nodules or infiltrative plaques. The presentation of ENTCL as a solitary ulcer, in the absence of other cutaneous lesions and systemic symptoms and signs, is extremely rare and may be easily misdiagnosed. In this report, we describe an unusual case of ENTCL with a diagnostically challenging clinical presentation as a solitary non-healing leg ulcer in an elderly woman.
