Study on association of cutaneous tuberculosis with pulmonary tuberculosis

Background: Tuberculosis continues to be a health problem in many countries. There may besimultaneous multiple organ involvement. Diagnosis of one organ disease may lead to missing offdiagnosis of other organ involvement. Objectives: The present study was done to analyze theassociation of cutaneous tuberculosis with pulmonary tuberculosis. Material and methods: Throughpurposive sampling a total of 23 patients of suspected cutaneous tuberculosis were primarily enrolledin this cross sectional study. History was taken and examinations were done to find out types ofcutaneous lesions and to explore a pulmonary involvement. Investigations including CBC with ESR,Mantoux test and Skin biopsy were done for each and every patient. Those who had cutaneous tuberculosis on histopathology chest x-ray were done to detect pulmonary lesions. After investigations 2 patients were excluded due to absence of tubercular infection. Finally 21 patients were included inthis study. Data were collected in a predesigned structured questionnaire. Results: Out of 21 patients16 (76.19%) were male and 5(23.81%) were female with a male to female ratio of 3.2:1. Age range varies from 5-70 years with a mean of 29.76±18.2 years. MT was positive in 76.20% of patients. CXRshowed 23.81% of the patients with cutaneous TB had simultaneous pulmonary involvement. The association is statistically significant (p 0.05). Conclusions: Patients with Cutaneous tuberculosis may have pulmonary involvement in a statistically significant number. In any patient with cutaneous TB,meticulous systemic examinations and relevant investigations have to be done to explore pulmonary involvement.
