Key result
Surgical excision of a 3-cm breast mass in a 17-year-old girl revealed myxoid fibroadenoma on histopathology.
Why the study?
Breast myxoid fibroadenoma is a rare histological variant that is either sporadic or associated with Carney complex, prompting a review and comparison with conventional fibroadenoma.
Case Report (n=1)
This case report highlights a rare histological variant of breast fibroadenoma, myxoid fibroadenoma, in a 17-year-old girl.
Supports including myxoid fibroadenoma in adolescent breast mass differentials; leaves open larger studies on recurrence and management.
Breast myxoid fibroadenoma (MFA) is a rare entity characterized by hypocellular myxoid stroma and is either sporadic or associated with the Carney complex, an inherited disorder caused by PRKAR1A -inactivating germline mutations. Here, we present the case of a 17-year-old girl who presented with a 3-cm mass in her left breast, suggestive of fibroadenoma. The mass was surgically excised, and histopathology revealed MFA. We sought to review breast MFA and compare it to conventional fibroadenoma.
