Macroscopic and histological findings of the excised specimen. (A) Gross appearance of the resected tissue: a relatively well-circumscribed, multinodular, gelatinous tumor without bleeding or necrosis. The tumor was located in the breast tissue but was close to the pectoralis major muscle. The surface of the pectoralis major muscle was partially resected with the tumor. (B) Microscopic examination of the resected specimen revealed the presence of mammary gland tissue surrounding the tumor. (C) Lipoblasts were also seen in the resected breast tumor. Histological features of the breast lesion were found to be identical to those of the primary lesion of the extremity. The Estrogen Receptor and Progesterone Receptor status of the histological material was negative.
