Two friends with eroded nodules on the ears: Atypical fibroxanthoma case report

Atypical fibroxanthoma is an uncommon mesenchymal tumor that manifests clinically as a reddish papule or nodule in sun-exposed areas of the body. the clinical presentation is not specific and histology and immunohistochemistry are both necessary for a correct diagnosis. surgery is the gold standard of therapy. recurrence and metastasis should be excluded with a follow-up at 6 months,since this tumor should nowadays be considered a medium-grade neoplasm,rather than low-grade as previously believed. we report the case of two friends who came to our hospital during the same period,complaining of very similar lesions. after biopsy and immunohistochemical examination,a diagnosis of atypical fibroxanthoma in both cases was formulated. © 2015 by anais brasileiros de dermatologia.
