Publication date: Available online 25 November 2016 Source:Dermatologica Sinica Author(s): Xiangang Fang, Huixian Li, Lankai Yi, Jiayou Xu, Xinbo Wang, Yunxiang Zhang, Zhenhua Wang Porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is a rare benign skin disease. Widespread involvement of PEODDN is more uncommon and its association with squamous cell carcinoma (SCC) is also rare. In this case report, we present the case of a 50-year-old woman with serious widespread PEODDN along Blaschko's lines and concomitant invasive SCC with lymph node metastasis. This was the first reported case of metastatic SCC arising from PEODDN.
