Abstract :
Introduction: Mycobacterial dermal lesions pose diagnostic challenge and require histopathological
examination for confirmation. Granuloma is an important histopathological feature present in most of
the mycobacterial dermal lesions. Multiple etiologies can produce an identical histopathological picture.
The present study was undertaken with the objective to study the spectrum of mycobacterial dermal lesions,
their etiologies and their incidence in this geographical area.
Materials and Methods: This present study was carried out in Department of Pathology G.K General
Hospital, Bhuj for a period of one year. A total of 50 cases mycobacterial dermal lesions of all etiologies
are included in the present study. Hematoxylin and eosin stain was routinely done on all cases. Special
stains like Ziehl-Neelsen, Fite Faraco, Periodic acid–Schiff stain were done whenever required.
Conclusion: Histopathology is gold standard to diagnose mycobacterial dermal lesions. Along with it, the
clinical presentation of the patient is also very important in elucidating the exact etiology.
