NGWISANYI, W; TSHIMBIDI, G; KEYTER, M  and  BEIM, C-A. Nipple-areolar complex: commonest site of breast leiomyoma. S. Afr. j. surg. [online]. 2022, vol.60, n.3, pp.213-215. ISSN 2078-5151.  https://doi.org/10.17159/2078-5151/sajs3869.

Breast leiomyomas are extremely rare and commonly seen in the nipple-areolar complex due to the presence of smooth muscle. Identification of this rare benign tumour is based on its location and the presence of spindle cells on histology. We report a case of a breast leiomyoma in a female patient who had a six-year history of a unilateral breast mass. Breast ultrasound and mammography demonstrated a sub-areola mass and an ultrasound-guided core biopsy revealed a benign spindle cell neoplasm with smooth muscle differentiation. The lesion was excised and final histology confirmed a leiomyoma with clear margins.

Keywords : breast leiomyoma; sub-areolar; rare tumour; smooth muscle.
