A rare case of Alveolar Soft-Part Sarcoma in the Uterine cervix.

Alveolar soft-part sarcoma (ASPS), a rare and malignant neoplasm of soft tissues, comprises less than 1% of all soft-tissue sarcomas and is characterized by distinct histopathological and molecular markers. A 27-year-old female presented with a history of postcoital vaginal bleeding and intermittent bleeding over the preceding month. Imaging studies identified abnormal echogenicity and vascular patterns in the posterior cervical lip. Initial histopathological assessment indicated a perivascular epithelioid cell tumor (PEComa) with TFE3 gene rearrangement; however, subsequent immunohistochemical and molecular analyses corroborated the diagnosis of ASPS. The patient underwent a total laparoscopic hysterectomy with bilateral salpingo-oophorectomy. Postoperative pathology revealed that the residual tumor was confined to the inner third of the cervix, with no evidence of lymphovascular or perineural invasion. The patient did not receive adjuvant therapy and was followed for three months postoperatively, during which no recurrence or metastasis was observed. Given the extreme rarity of ASPS, its diagnosis necessitates meticulous scrutiny by pathologists to inform and guide subsequent therapeutic approaches.
