Explanation

A 45 year old man consulted a doctor about a plaque-like formation on his neck. Histological examination of a skin bi-optate revealed clusters of round and oval tumour cells with a narrow border of basophilic cytoplasm resembling of cells of basal epidermal layer. What tumour is it?Basal-cell carcinoma (BCC), also known as basal-cell cancer, is the most common type of skin cancer. It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it; or it may present as a raised area with ulceration. It grows slowly and can damage the tissue around it but is unlikely to spread to distant areas or result in death.
