Diagnosis

Juvenile Fibroadenoma

Findings

US – Transverse and longitudinal images show a large (9.8 × 9.6 × 7.4 cm) circumscribed solid right breast mass with uniform echogenicity and mild hyperemia on Doppler.

Discussion

Juvenile fibroadenoma is an uncommon histologic variant of fibroadenoma that frequently undergoes markedly rapid growth. A fibroadenoma over 5–10 cm in diameter is termed a giant fibroadenoma. Although most giant fibroadenomas are of the cellular subtype, not all cellular fibroadenomas are giant. Juvenile fibroadenomas most often occur in African American adolescent girls. Approximately 10%–25% of patients with juvenile fibroadenomas have multiple or bilateral tumors at presentation. Patients with a juvenile fibroadenoma typically present with a rapidly enlarging breast; skin ulceration or distended superficial veins may be present.
