Carcinoma urotelial primario de la trompa uterina, una patología infrecuente: reporte de un caso

Abstract

Primary Carcinoma of the uterine tube is an unusual malignant pathology that occurs between the 0,1% and the 1,8% of all malignant tumors, being the urothelial histological type even less frequent, which represents 10% of malignant tumors of the uterine tubes. These tumors usually appear in women between the 5th and 7th decades, and in 18% of the cases they become clinically manifest with the following triad: palpable mass and/ or abdominal distention, pain, and metrorrhagia. We present a case of a 44 year old woman who began current pathology in December 2010 with pelvic pain and continuous genital bleeding. The magnetic resonance reported a lesion that occupied the right parauterine space, and suggested a malignant neoplasia of the right ovary. The report of Ca-125 tumor marker showed high values, along with symptoms and paraclinic results that suggested a malignant disease. A gynecologic laparotomy was performed, with evidence of a right Fallopian tube tumor. The histological study was concluded as a Carcinoma with Urothelial differentiation. Afterwards, a staging surgery was performed, which included peritonea washing out, total hysterectomy, left salpingo-oophorectomy, omentectomy, appendicectomy, and selective, bilateral lymphadenectomy. The biopsy report from the surgical pieces was negative for malignancy. Actually, the patient is disease-free. This case was reported given the unusual of the pathology.
