Uterine carcinosarcoma with concurrent right nephrolithiasis case report.

aimUterine carcinosarcoma (UCS) is a rare and highly invasive gynecological malignancy with insidious clinical manifestations, particularly in underdeveloped regions where patients often neglect routine health screenings, missing the optimal opportunity for early intervention. This report aims to enhance the understanding of UCS by presenting the diagnosis and treatment process of a case. CASE PRESENTATION: A 57-year-old woman with right lumbar pain underwent B-ultrasound at a local health center, which identified a right renal stone. During the abdominal examination, a palpable mass was noted in the right lower abdomen. An magnetic resonance imaging (MRI) performed at our hospital revealed a large, irregular mass in the pelvic cavity, showing mixed abnormal signal intensity, measuring approximately 100 mm × 50 mm × 40 mm (left-right × anterior-posterior × craniocaudal diameter). Histopathological analysis of the resected tissue confirmed uterine carcinosarcoma.

conclusionUCS is a rare and highly aggressive malignancy. Owing to its subtle early clinical manifestations, it is frequently diagnosed at intermediate or advanced stages. Early detection and timely treatment are critical for improving patient outcomes. Raising awareness of the importance of regular health check-ups among postmenopausal women is essential.
