Fibroadenoma in axillary breast tissue - Utility of rapid on-site evaluation & report of two cases.

Fibroadenoma of axillary breast tissue presents as a palpable mass, cyclic pain in the axilla, and with asthetic concerns. Axillary breast tissue can occur anywhere along the primitive embryonic milk lines, extending from the axilla to the groin, and can present unilaterally or bilaterally. The reported incidence of axillary breast tissue is 0.4%-6% in females. We had two cases of fibroadenoma in the axilla that were diagnosed on rapid on-site evaluation and later confirmed by routine cytology stains in young females. We report the cases for their rarity and high degree of clinical suspicion in the young reproductive age group female. We also emphasize the utility of ROSE in cytopathology.
