Résumé
This study was done on 80 cases of granulomatous diseases of the skin. These patients were subjected to full history, clinical examination and elliptical skin biopsy for histopathological examination by light microscopy using hematoxylin-eosin stain and special stains. Special stains were done for confirmation of the diagnosis in some cases as follow: Ziehl-Neelsen stain for tuberculosis, modified Ziehl-Neelsen stain for leprosy, Giemsa stain for leishmaniasis, periodic acid- Schiff and Grocott-Gomori stains for deep fungus, and reticulin stain for sarcoidosis. Leprosy represented the commonest type of skin granulomas [25%] of the cases. The age group between 30 - 40 years represented the highest incidence in most cases of skin granuloma, while cutaneous tuberculosis is more in younger age group [mean age 25.5 years]
