Pagetoid reticulosis after radiotherapy of primary cutaneous anaplastic large-cell lymphoma.

We describe a 60-year-old man with a history of primary cutaneous anaplastic large cell lymphoma on the chest, who presented with a new scaly red plaque on the same site 11 years after radiation therapy. Histological examination revealed a dense epidermotropic infiltrate of atypical mononuclear cells consistent with pagetoid reticulosis. Immunohistochemistry revealed the infiltrate to be CD4, CD8, and CD30.

The extent of dermatopathology education: a comparison of pathology and dermatology.

An indispensable component of all pathology and dermatology residencies is obtaining proficiency in the area of dermatopathology. The purpose of this study is to quantify dermatopathology training in pathology and dermatology residencies and the amount of continuing medical education in dermatopathology in leading journals of both fields. Dermatology residents complete more hours of dermatopathology than pathology residents.

Low-dose thalidomide therapy for refractory cutaneous lesions of lupus erythematosus.
