Pattern of Local Recurrence and Metastasis in Carcinoma Breast According to Molecular Subtype in Patients Treated with Definitive Intent

[摘要] BACKGROUND Paratesticular tumors (PTTs) are less commonly encountered and account for 7%–10% of all intrascrotal tumors. PTT can originate from spermatic cord, epididymis, and testicular tunica. Seventy-five percent of cases originate from spermatic cord, however, usually the exact origin cannot be differentiated. PTT can be benign or malignant. Although only 30% of paratesticular masses are malignant, 90% of them are sarcoma. Genitourinary sarcomas are 2.7% of all sarcomas but specifically paratesticular sarcoma (PTS) accounts to only 1% of all adult sarcoma. PTS can occur at any age with a median age of 52 years. Ninety-two percent of cases present with localized disease, 5.9% with nodal involvement, and 1.9% with metastasis. Histopathologically, most of the PTS are rhabdomyosarcoma, leiomyosarcoma, or liposarcoma. Epithelioid sarcoma (ES) has been rarely reported. Here, we report the fourth case of paratesticular ES in the literature to the best of our knowledge and have compared it to the previous reported cases [Table 1].
