Blue nevus is a type of uncommon benign pigmented lesion in the skin or the mucosa of human body which is featured by pigmented dendritic melanocytes and spindled melanocytic cells. Sinonasal blue nevus is extremely rare. We reported a sinonasal blue nevus case with the background of pituitary adenoma, type 2 diabetes mellitus, and hypertension (including endoscopic and histological pictures). Further, the existing literature about blue nevus is reviewed. This paper puts a spotlight on the potential correlation between blue nevus with the endocrine system disorder and provides support for further experimental research.

Review
Melanocytic lesions have a wide morphological spectrum, ranging from benign nevi to malignant melanoma. In contrast to a diagnosis of a benign nevus, a diagnosis of melanoma could mean intensive treatment, lifetime monitoring, and a worse prognosis. Therefore, melanocytic tumors are notoriously challenging and associated with a high risk of litigation in surgical pathology. After describing the basic features of nevi and melanoma, this article describes the detailed clinical and histological features of those lesions that share many similar features with melanoma. The entities included are Spitz nevi and atypical Spitz tumors (AST), Reed nevus, dysplastic nevus, cellular blue nevus (CBN), deep penetrating nevus, combined nevus, recurrent nevus, irritated nevus, congenital pattern nevus, acral nevus, and nevi of special sites. Knowledge of these imitators can help pathologists distinguish between benign and malignant cases and avoid misdiagnosis.

The term "Mongolian Spot" rather than the preferred descriptive name congenital dermal melanocytosis (CDM) continues to be used despite compelling objections to the contrary. Terms that stigmatize a culture, region, people, country, communities, and ethnic group should be replaced by their more descriptive counterparts. Herein, we clarify terminology, discuss the historical significance, and provide a recommendation about naming this disease.
