Spontaneous Infarction in a Fibroadenoma of the Breast

SUMMARY: BACKGROUND: Fibroadenomas are common neoplasms in young women but occur in a wide age range from adolescent females to octogenians. CASE REPORT: A 21-year-old female patient presented with a 10-week history of a mass in her breast. Ultrasound examination demonstrated a 3.5 × 3 cm, well-circumscribed, semisolid mass. An excisional biopsy but no fine needle aspiration was performed. The patient had no history of pregnancy or lactation, or trauma or infection to the area of the lesion. The histopathological examination showed a spontaneously infarcted fibroadenoma. CONCLUSIONS: Spontaneous infarction is an uncommon complication in fibroadenoma of the breast, and there are very few reported cases in the literature.
