# Genital Tuberculosis and Serous Cystadenoma in a 58-Year-Old Female With Rheumatoid Arthritis and Sjögren's Syndrome: A Case Report

## TL;DR

A 58-year-old woman with autoimmune conditions was diagnosed with genital tuberculosis and a cystadenoma, highlighting the need for accurate diagnosis to avoid misdiagnosis as cancer.

## Contribution

This case report highlights the rare coexistence of genital tuberculosis and serous cystadenoma in an immunocompromised patient.

## Key findings

- Genital tuberculosis was confirmed via histopathology and RT-PCR in a patient with rheumatoid arthritis and Sjögren's syndrome.
- The patient's symptoms and imaging initially suggested ovarian cancer, but further testing revealed tuberculosis.
- Prompt antituberculosis treatment led to significant clinical improvement.

## Abstract

Genital tuberculosis (GT) is a rare but significant extrapulmonary tuberculosis form, often mimicking ovarian malignancy. We report a case of a 58-year-old woman with Sjögren's syndrome and rheumatoid arthritis, previously treated with infliximab, who presented with abdominal distension, weight loss, night sweats, and intermittent abdominal pain. Initial imaging and elevated CA-125 levels suggested ovarian cancer. However, intraoperative findings revealed a frozen pelvis with granulomatous inflammation, caseating granulomas, and Langhans' giant cells. Histopathological analysis and RT-PCR confirmed GT coexisting with a serous cystadenoma. GT should be considered in the differential diagnosis of pelvic masses, especially in immunocompromised patients. This case emphasizes the importance of thorough diagnostic evaluation using molecular, serological, and imaging techniques to avoid misdiagnosis and unnecessary surgical interventions. Prompt initiation of antituberculosis treatment led to significant clinical improvement. Early and accurate diagnosis of GT is crucial to prevent morbidity associated with misdiagnosis and to provide effective treatment. This case underscores the need for heightened clinical awareness and multidisciplinary approaches in managing complex cases where GT mimics malignancy, ensuring optimal patient outcomes.
