Sekkat, M. Alami Merrouni, M. Bendahhou Idrissi, K. Saoud, N. Mamouni, S. Errarhay, C. Bouchikhi, A. Banani Abstract: Leiomyomas, originating from smooth muscle and primarily identified in the gastrointestinal tract and uterus, are rare non-malignant tumors. In breast pathology, leiomyomas are exceptionally rare, constituting less than 1% of all breast neoplasms. This narrative presents a case of a 35-year-old woman diagnosed with breast leiomyoma, exploring its immunohistochemical and histological characteristics, and discussing relevant literature. The clinical, radiological, and pathological features align with common benign lesions, emphasizing the diagnostic challenges of breast leiomyomas. The presented case involves a pregnant woman with a painless subareolar mass, showcasing consistent radiological findings. An ultrasound-guided breast core biopsy confirmed the leiomyoma diagnosis, supported by immunohistochemical analysis. Despite initial reluctance for surgical resection, understanding the rarity and potential diagnostic challenges of breast leiomyomas remains crucial. This case contributes to the growing body of knowledge on these uncommon breast tumors, highlighting the significance of comprehensive diagnostic approaches.
