Solid Fibroadenoma Tumor Located (Breast)

Description

Cut through a female breast in cross-section, the illustration traces the skin and superficial fascia overlying lobulated adipose tissue, then the glandular parenchyma with lobules draining into lactiferous ducts that converge toward the nipple-areolar complex. A well-circumscribed, solid fibroadenoma sits within the glandular tissue, typically surrounded by compressed parenchyma and thin fibrous stroma rather than infiltrating adjacent fat. Posteriorly, the deep fascia separates breast tissue from the pectoralis major muscle on the anterior chest wall, while branching vessels and lymphatic channels course through the interlobular connective tissue. Fibroadenoma is the prototypical benign solid breast mass in adolescents and young adults, and this sectional view supports teaching why it is usually mobile on exam, it expands by pushing rather than invading, and it often appears as an oval, circumscribed hypoechoic lesion on ultrasound. Its relationship to ducts and lobules also frames the key differential with phyllodes tumor, which can look similar but tends to grow rapidly and warrants wider excision, and it reinforces why a core needle biopsy samples both the stromal and epithelial components when imaging and clinical findings do not align. Clear margins matter. Use this artwork for anatomy and pathology lectures on the mammary gland, radiology teaching files discussing BI-RADS assessment of a palpable mass in a young woman, or patient-facing surgical consult materials explaining lumpectomy planning relative to the nipple, ductal system, and pectoralis fascia.
