This clinical photograph consists of two panels illustrating gross pathological findings in the breasts. Panel (a) provides a comparative view of both breasts, demonstrating significant asymmetry; the left breast is markedly enlarged and swollen relative to the right. Panel (b) offers a close-up perspective of the left breast, highlighting diffuse erythema (redness) and skin changes consistent with inflammation. A distinct discharging sinus is visible in the medial quadrant, located just medial to the left nipple-areolar complex. The surrounding skin exhibits a thickened, edematous texture, occasionally referred to as peau d'orange appearance in such clinical contexts. These visual signs—swelling, redness, and a draining sinus tract—are characteristic markers of a severe inflammatory process, such as inflammatory breast cancer, complicated mastitis, or a ruptured mammary abscess. The image serves as an educational tool for recognizing clinical signs of advanced breast pathology and associated cutaneous manifestations.

This clinical photograph displays a close-up view of the left breast upper outer quadrant and the left axillary region. The image demonstrates significant dermatological findings including diffuse erythema (redness) and pronounced soft tissue edema (swelling), which distorts the normal anatomical contours of the axillary fold. The skin surface exhibits an uneven texture with areas of thickening and subtle wrinkling, consistent with peau d'orange or inflammatory infiltration. Scattered across the erythematous region are several pinpoint petechiae or small angiomatous red spots. These findings are clinically significant as they can represent an inflammatory presentation of breast malignancies, such as inflammatory breast cancer or, as in this specific clinical context, primary breast lymphoma. The image serves as an educational example of how systemic or malignant processes can manifest with localized skin changes mimicking cellulitis or mastitis.
