Abstract :

Cysts are commonly encountered lesions in histopathology. Epithelial cysts are classified into epidermal, trichilemmal and dermoid cysts based on the structural composition of wall. Objective of the study is to determine the age, sex and site distribution and detailed histomorphological characteristics of epithelial cysts of skin. A retrospective study conducted for a period of 5 years at a tertiary care hospital. Out of 94 cases, epidermal cysts were the most common type (77%) followed by pilar cysts (17%) and dermoid cysts (6%). Age distribution was wide. Epidermal cysts were seen commonly in males where as pilar cysts in females. Demoid cysts did not show any sex predilection. A spectrum of secondary changes like infection, giant cell reaction, calcification, cholesterol cleft formation and neoplastic transformation were observed. Though the clinical diagnosis may be as simple as sebaceous cyst it is necessary to study these cysts in detail because of their varied morphological presentations.
