case_images: Data System (BI-RADS) 4 due to the presence of a hyperdense, lobular, and well-circumscribed nodule, suggested as a suspicious lymph node (Figure 1). By ultrasound (US) imaging, hypoechoic nodule measuring 1.26 x 1 cm was identified, with indistinct microlobular margins and without vascularity identified by Doppler (Figure 2). During physical exploration, there was only the presence of bilateral ectopic axillary breast tissue with a volume of 8 x 8 cm, without palpable lumps in the patient's mammary glands or in the ectopic tissue.

case_images: The gross description reported a round multinodular soft mass, 1.8 x 1.2 cm in dimension; tumor demonstrated a white cut surface and well-circumscribed lobulated contours, focal with irregular borders (Figure 4).
case_images: (a, b) H&E x10 intracanalicular pattern forming cleft-like spaces; the stroma is mildly atypical with one mitosis per 10 high-power field.
