Breast Lesions in Women Aged Younger than 30 Years: Clinical Presentation, Diagnosis, and Management.

Women aged younger than 30 years frequently present with palpable breast lesions, breast pain, and nipple discharge. Diagnostic work-up often results in benign findings, including a variety of benign solid masses, infectious or inflammatory conditions, pregnancy- or lactation-related abnormalities, and normal variants. While rare, breast cancer can occur within this demographic, and it is often more advanced and aggressive than in older women. Other rare tumors can present within this patient demographic, including primary sarcoma of the breast and granular cell tumors. A knowledge of the clinical presentation, diagnostic approach, and management of this spectrum of pathologic entities is crucial to ensure optimal and cost-effective care within this patient demographic.

Radiologic and histologic presentation of male mammary myofibroblastoma.

Mammary myofibroblastoma is a rare mesenchymal neoplasm that typically presents in older men and women. Less commonly, these benign tumors may also occur in soft tissues located outside of the breast, in which case they are referred to as mammary-type myofibroblastomas. The histologic composition of this benign spindle cell tumor can be markedly varied. We present a case of a large mammary myofibroblastoma in a male patient and discuss the typical imaging and histologic makeup of these tumors.
