Histopathological study of dermal granuloma

ABSTRACT

INTRODUCTION:The objectives of this study were to confirm the diagnosis of clinically suspected dermal granuloma- tous diseases by histopathological examination and by routine and special stains as well as to study the incidence of various types of dermal granulomas.MATERIALS AND METHODS:This study was conducted at the Department of Pathology in collaboration with De- partment of Skin and Venereal disease. A total of 90 cases from outdoor patient department of skin and venereal disease, which were clinically diagnosed as suspected dermal granulomatous diseases, were taken as the study population.RESULTS:In our study, we found that leprosy had the highest incidence (50%), followed by cutaneous tuberculosis (30%) among all dermal granulomatous diseases like syphilis, fungal, granuloma annulare, foreign body, actino- mycosis, and sarcoidosis. Dermal granulomas were most common in middle age between 21 and 40 years of age.CONCLUSION:Histopathology played an important role in the final diagnosis of dermal granulomatous lesions. Most common dermal granulomatous disease was leprosy, followed by cutaneous tuberculosis.
