definitionSpitz nevus is a benign melanocytic nevus with a characteristic histological appearance. It is otherwise known as benign juvenile melanoma or nevus of spindle/epitheliod cell type. Most lesions are under 1 cm in diameter and the majority are pink to red in colour and may be mistaken for a pyogenic granuloma. Histological examination shows an intense melanocytic activity around the dermo-epidermal junction. Large numbers of spindle-shaped melanocytes proliferate downward toward the dermis and usually a large amount of pigment is present. |
