Abstract
- Blue nevus is a neoplasm composed of pigmented dendritic dermal melanocytic cells in the reticular dermis. The lesion clinically presents as a well dermacated cerulean-blue or bluish black colored papule or plaque that usually measure less than 1 cm in diameter. Pilar sheath acanthoma is a rare, benign follicular hamartoma commonly affecting middle-aged and elderly individuals. It is characterized by a small, solitary, skin colored papule situated on the head and neck, particularly around the upper lip. We report a rare case of a blue nevus associated with a pilar sheath acanthoma in a 26 year-old man presented with a bluish papule on the neck.
