case_images: Photomicrograph of the fine needle aspiration cytology.. Fine needle aspiration cytology smear at low power microscopy from the mass black arrow showing cohesive clusters of ductal cells in branching pattern, blue star showing numerous scattered bare nuclei, and blue arrows showing fat cells. (Wright stain, 50X magnification.)

case_images: FNAC smears (Figure 2) revealed moderately cellular and show sheets of epithelial cells showing the bimodal population of ductal epithelial cells and myoepithelial cells along with fragments of mature adipose tissue in lipo hemorrhagic background; these features are consistent with gynecomastia, the axillary tail of breast region.

case_images: Photomicrograph depicting breast tissue.. Photomicrograph of the mass showing fibrofatty breast tissue with hyalinized stroma surrounding dilated and proliferated ducts (red arrow), fat cells (white arrow), intralobular ducts (black arrow), and adjacent clusters of apocrine glands (blue arrow) seen in the dermis of the axillary skin. (H&E stain, 20X magnification.)

case_images: The excised specimen was sent for histopathology examination (Figures 4, 5), which revealed fibro adipose tissue with the presence of terminal duct lobular units with cystically dilated acini and focal mild epithelioid; there was no sign of atypia or malignancy, final impression was accessory axillary breast.
case_images: Photomicrograph A shows proliferated ducts lined by epithelial and myoepithelial cells set in a fibrous stroma, photomicrograph B shows ducts with mild epithelial hyperplasia (black arrow).. 5A: H&E stain, 100X magnification; 5B: H&E stain, 200X magnification.
