case_images: These were irregularly shaped and distributed in an annular pattern around the nipple of the right breast (Figure 1).
case_images: Clinical findings. Ten months post-initial visit: expansion of the erythematous patches and plaques on the right breast, extending to the contralateral side

case_images: The erythematous macules and patches on the left breast began to coalesce (Figure 2).
case_images: Histological findings . Dysplastic cell infiltration with a high nuclear-cytoplasmic ratio in the superficial dermis and visible ductal formation was noted (hematoxylin-eosin stain, x40).

case_images: A skin biopsy of the newly appeared annular lesion on the left breast revealed dysplastic cell infiltration, characterized by a high nuclear-cytoplasmic ratio, in the superficial dermis (Figures 3 and 4).
case_images: Histological findings . Dysplastic cell infiltration with a high nuclear-cytoplasmic ratio in the superficial dermis and visible ductal formation was noted. The lymphovascular invasion of tumor cells, indicated by a black arrow, suggests inflammatory breast carcinoma (hematoxylin-eosin stain, x100).

case_images: A skin biopsy of the newly appeared annular lesion on the left breast revealed dysplastic cell infiltration, characterized by a high nuclear-cytoplasmic ratio, in the superficial dermis (Figures 3 and 4). Furthermore, lymphovascular invasions of tumor cells, suggesting inflammatory breast carcinoma, were noted in the reticular dermis (Figure 4).
