AB  - OBJECTIVE: To describe the histopathological pattern of skin diseases in patients from the western region of Saudi Arabia and to compare this with previously published data from other regions in Saudi Arabia and worldwide.METHODS: A retrospective review of all skin biopsies received and reported by the Department of Pathology, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia between January 2005 and December 2010. Neoplastic and non-neoplastic category were divided into melanocytic and non-melanocytic subcategories. Non-neoplastic category was divided into the following subcategories: dermatitis, infection, vascular, vesiculobullous, connective tissue disease, drugs, panniculitis, non-infectious granuloma, degenerative, metabolic, and pigmentary.RESULTS: Three hundred and sixty skin biopsies were reviewed. Out of these, 207 (57.5%) were non-neoplastic skin diseases, while 153 (42.5%) were neoplastic. Both non-neoplastic (female to male ratio of 1.3:1) and neoplastic (female to male ratio of 1.2: 1) categories were more common in females than in males. Among the non-neoplastic category, the most common diagnosed subcategory was vesiculobullous disease (n=46, 22.2%), followed by dermatitis (n=30, 14.5%). The neoplastic category was divided into melanocytic (n=31, 20.3%) and non-melanocytic neoplasms (n=122, 79.7%). Both neoplastic and non-neoplastic categories were most common in the age group of 46 years and older.CONCLUSION: Vesiculobullous diseases, dermatitis, and infections are the 3 most common non-neoplastic skin diseases and the most common neoplastic are benign non-melanocytic neoplasms. The prevalence of neoplastic and non-neoplastic skin diseases in general increases with age.
