Clear cell hidradenoma. Would do a small IHC panel to rule out usual mimics and demonstrate ducts.

Age and very low nuclear grade ( TFE3pos of young people RCC r usually higher grade) and hyaline material and absence of red cells make me favor CCH. But IHC and CPC is mandatory.

Yes this was a nice example of a typical clear cell hidradenoma.  Referred with supportive immunohistochemistry (EMA ++20% highlighting cystic areas; CEA polyclonal lines cystic spaces, Cam5.2 highlights lining and peri-lining cells. RCC marker -ve; S100-ve. PAS not much glycogen or mucin).
