The Challenge of Distinguishing Cylindroma of the Breast from Adenoid Cystic Carcinoma: A Case Report and Review of this Rare Tumor

Background: Cylindroma of the breast is a rarely described tumor that closelyresembles its dermal counterpart.Case presentation: We report a case of a ۵۵-year-old woman with an incidentalfinding of a left breast mass on screening mammography. On histologicexamination, the tumor was found to be consistent with cylindroma of the breast.Conclusions: Generally considered to be a benign lesion, cylindroma of thebreast may be challenging to differentiate from morphologically similar tumors,such as solid type adenoid cystic carcinoma, and this uncertainty may lead to adilemma in treatment options. These patients should be followed closely, as longtermoutcome data is not available given the uncommon occurrence of theselesions within the breast.
