Abstract
Cutaneous intravascular CD30+ pseudolymphoma is an uncommon incidental finding that may mimic intravascular or angiotropic lymphoma. We describe a 78-year-old female with a traumatized regressing keratoacanthoma on her left cheek. A shave biopsy was performed which revealed intravascular staining of atypical lymphocytes positive for CD45, CD3 and CD30. Clinical exam revealed no other evidence of lymphoma, the patient denied constitutional symptoms, and routine blood work was normal. The patient is healthy and doing well 28 months after her first visit. CD30+ pseudolymphoma should be distinguished from malignant intravascular lymphoproliferative disorders.
