Desmoid tumors are rare, benign fibroblastic tumors that are locally infiltrative and can cause extensive morbidity by destruction of adjacent vital structures. Due to the rarity of these tumors, evidence regarding optimal treatment protocols is drawn from case reports and single-arm series with small patient numbers. We report a case of a patient with a desmoid tumor of the left supraclavicular region that was diagnosed and treated in our department and a review of the current literature.

The mixed epithelial and stromal tumor family of kidney contain neoplasms with biphasic epithelial and stromal component. According to the 2016 World Health Organization Classification, they encompasses a spectrum of tumors ranging from predominantly cystic tumors (adult cystic nephroma) to tumors that are variably solid (Mixed epithelial and stromal tumor-MESTs). We present the case of a 20-year-old woman with an adult cystic nephroma which was verified by immunohistochemical examination.
