A 50-year-old female patient without active sexual life admitted to Department to Surgery with a swelling over the left inguinal area with discharging sinus from labia majora to left inguinal crease. She had history of incision and drainage for an abscess at left labia majora 6 months back. She had no history of cough, fever, or abdominal pain. She had not been in close contact with an index case of pulmonary tuberculosis in past year. Antibody tests for HIV and VDRL infection were negative.
Chest and abdominal X-rays were normal. Ultrasonography revealed that the uterus was bulky and endometrial line was not visualized and bilateral adnexae were without a mass or cyst. A full blood count showed leucopenia, and ESR at 2 hours was 55.
Then patient underwent excision of the sinus tract of labia through suprapubic approach after staining it with methylene blue. A mass of  cm was excised in the retropubic region  (see Figures 1(a), 1(b), and 2). Histopathology report showed sinus tract lined by chronic inflammatory cells, epitheloid cells, and Langhan's giant cells on microscopic examination suggestive of tuberculous sinus (Figure 3). Antitubreculous quadruple therapy was initiated. Complete healing of the wound, with rapid relief of symptoms, followed 4-week antituberculosis chemotherapy.
