Fibroadenoma

Summary of Fibroadenoma
Fibroadenomas of the breast are benign tumors characterized by an admixture of stromal and epithelial tissue. Since both fibroadenomas and breast cancer can appear as similar lumps, it is currently recommended to perform ultrasound analyses and possibly tissue sampling with subsequent histopathologic analysis in order to perform diagnosis. Unlike typical lumps from breast cancer, fibroadenomas are easy to move, with clearly defined edges. Fibroadenomas are sensitive to estrogen and therefore can enlarge in women on oral contraceptives and during pregnancy.

Her only medication is an oral contraceptive pill. Physical examination shows a firm, mobile mass in the right upper quadrant of her right breast that is roughly 2-cm in diameter. There is no erythema, nipple retraction, or other abnormalities noted with the overlying skin. No lymphadenopathy is noted. She is referred for core tissue biopsy of the mass, which is shown in the image below. Which of the following is the most likely diagnosis?
