Abstract
A 70-year-old African American female with a history of stage IV mycosis fungoides in remission presented with a gradually enlarging, red, ulcerated nodule on her right dorsal hand. The lesion was biopsied, and it showed intraepidermal proliferation with cytologic atypia and increased vasculature in the papillary dermis. Immunohistochemical staining indicated a yes-associated protein 1 (YAP1) rearrangement, confirmed by RNA sequencing, revealing a YAP1::MAML2 (mastermind-like transcriptional coactivator 2) fusion. The lesion was diagnosed as an eccrine porocarcinoma (EPC). The occurrence of EPCs following radiotherapy or trauma has been documented. This case highlights the importance of considering EPCs in patients with extensive skin treatments and immunosuppression history.
一位 70 岁的非裔美国女性,曾患真菌病 IV 期,病情缓解后出现右手背上一个逐渐增大的红色溃疡性结节。对病灶进行了活组织检查,结果显示表皮内增生,细胞学不典型,乳头状真皮内血管增多。免疫组化染色显示,YAP1(Yes-associated protein 1)重排,RNA测序也证实了这一点,发现YAP1::MAML2(类主控转录辅激活剂2)融合。该病变被诊断为非肾孔癌(EPC)。有文献记载,放疗或创伤后会出现 EPC。本病例强调了在有大量皮肤治疗和免疫抑制史的患者中考虑 EPC 的重要性。
期刊介绍:
Published monthly, the International Journal of Dermatology is specifically designed to provide dermatologists around the world with a regular, up-to-date source of information on all aspects of the diagnosis and management of skin diseases. Accepted articles regularly cover clinical trials; education; morphology; pharmacology and therapeutics; case reports, and reviews. Additional features include tropical medical reports, news, correspondence, proceedings and transactions, and education.
The International Journal of Dermatology is guided by a distinguished, international editorial board and emphasizes a global approach to continuing medical education for physicians and other providers of health care with a specific interest in problems relating to the skin.
