Abstract :

Introduction: Cutaneous tuberculosis is caused by Mycobacterium tuberculosis. Extra pulmonary Tuberculosis(EPTB) constitutes about 15–20% of TB cases and can constitute up to 50% of TB cases in HIVinfected individuals 1.Materials and methods:Thirty one consecutive skin biopsy samples were taken from Skin OPD and processed in Microbiology Department,UCMS & Guru Teg Bahadur Hospitals,Delhi.ZiehlNeelsen smear,Auramine stain and culture were performed on biopsy samples, Results: Out of 31 biopsy samples, Acid fast bacilli was seen in 2 samples by ZN staining method and growth was found in 6 samples only. Conclusion :Diagnosis of Cutaneous tuberculosis (TB)can be baffling, compelling a high index of suspicion owing to paucibacillary load in the biopsy specimens. Although culture methods is gold standard in diagnosis of TB but larger duration of growth period leads inefficiency of the method in high risk patients.
