Tuberculosis of other female genital organs
Clinical Classification Guidelines
Inclusion Terms
- Tuberculous ulceration of vulva
Medical Intelligence & Overview
Tuberculosis of other female genital organs, classified under ICD-10 code A18.18, is a rare form of extrapulmonary tuberculosis that affects parts of the female reproductive system other than the more commonly affected ovaries and fallopian tubes. This condition can involve organs such as the vulva, vagina, cervix, or uterus. It is caused by the spread of Mycobacterium tuberculosis, the bacteria responsible for tuberculosis, to these reproductive organs. One notable manifestation is tuberculous ulceration of the vulva, which can lead to painful sores and tissue destruction. Recognizing this condition is essential for timely treatment and proper management.
Causes & Symptoms
Clinical Causes: Spread of tuberculosis bacteria from the lungs through the bloodstream or lymphatic system to the genital organs. Direct extension from nearby infected tissues. Reactivation of dormant tuberculosis bacteria within the genital tissues. Concurrent active tuberculosis in other parts of the body.
Key Symptoms: Vaginal or vulvar ulcers or sores, often painful. Abnormal vaginal bleeding or discharge. Pelvic pain or discomfort. Swelling or lumps in the genital area. Weight loss and general malaise in advanced cases. Fever and night sweats in some cases.
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical examination, laboratory tests, and imaging studies. A biopsy of affected tissues may reveal granulomatous inflammation characteristic of tuberculosis, often with caseating necrosis. Microbiological tests, including acid-fast bacilli (AFB) staining, culture, and molecular techniques like PCR, can detect Mycobacterium tuberculosis. Imaging modalities such as ultrasound or MRI may help assess the extent of tissue involvement. A thorough medical history and screening for tuberculosis elsewhere are also vital components of diagnosis.
Treatment Protocols: Treatment primarily involves a prolonged course of anti-tuberculous medications, typically a combination of drugs like isoniazid, rifampicin, ethambutol, and pyrazinamide, over several months. Surgical intervention may be necessary in cases with extensive tissue damage, abscess formation, or non-healing ulcers. Supportive care focuses on maintaining hygiene, managing pain, and preventing complications. Close follow-up with healthcare providers ensures effective response to therapy and monitors for potential side effects.
