Toxicoderma Secondary to 5-Fluorouracil: Differential Diagnosis of Paraneoplastic Pemphigus
نویسندگان
چکیده
We present the case of a patient undergoing chemotherapy with 5-Fluorouracil (5-FU), irinotecan and cetuximab, who presented polymorphous skin lesions with oral and genital mucosal involvement. The differential diagnosis included paraneoplastic pemphigus, a severe autoimmune disease associated with neoplasms. The histology can be variable with acantholysis or lichenoid dermatitis. The presence of circulating antibodies supports the diagnosis. In our case, the anatomopathological and immunological findings and the clinical improvement after the suspension of 5-FU confirmed that it was toxicoderma secondary to the latter.

A variety of clinical and histological presentations can accompany the evolution of malignant melanoma. Unusual cytological variants of malignant melanoma include balloon cell, signet ring cell, myxoid and other metaplastic changes. With the exception of a case of pemphigus-like changes associated with malignant melanoma in paraneoplastic pemphigus, acantholysis is not a common histopathologica...

متن کاملImmunoapheresis in paraneoplastic pemphigus.
BACKGROUND Paraneoplastic pemphigus was first described in 1990 in 5 patients with extensive mucocutaneous erosions, a distinct set of autoantibodies, and underlying neoplasia. Since then, patients described have been middle-aged, have suffered from prognostically unfavorable malignant neoplasms, and have responded poorly to immunosuppressive agents. OBSERVATION A 16-year-old boy was examined...
