Blue nevus est species nevi colorati, typice unicus nodus bene demarcatus, caeruleus vel niger. Color caeruleus nevi causatur a cellulis pigmentariis in cute profunda.
Interdum fit biopsia vel totalis excisio chirurgica. Exitus clinicus plerumque bonum est, et casus mutationis carcinomatosae sunt rari. Diagnostica differentialis includit dermatofibroma et melanoma.
Blue nevus is a type of melanocytic nevus. The blue colour is caused by the pigment being deeper in the skin than in ordinary nevi. In principle they are harmless but they can sometimes be mimicked by malignant lesions, i.e. some melanomas can look like a blue nevus.
Quia cellulae nevus penitus praesentes sunt, caeruleum videtur.
Exemplum atypicum Blue nevus plerumque symmetriam habet. Cellulae basales carcinoma et melanoma in talibus distinguendae sunt.
Blue nevus refertur ad globum cutis incrementorum melanocytarum ex nimio incremento, qui caerulei ad nigras labefactat in capite, brachiis vel clunibus apparens. Solent esse solitaria et acquisita, sed etiam a nativitate praesens esse et in pluribus locis fieri possunt. Hae laesiones saepe confunduntur cum incrementis pigmentatis veluti melanomatis obscurioribus; typice apparent in cute, brachiis, dorsis inferioribus vel clunibus. The term blue nevus describes a group of skin lesions characterized by dermal proliferation of melanocytes presenting as blue to black nodules on the head, extremities, or buttocks. In most cases, they are acquired and present as a solitary lesion but may also be congenital and appear at multiple sites. Blue nevi are melanotic dermal lesions that commonly presents as a blue nodule on the scalp, extremities, sacrococcygeal region, or buttocks. Its characteristic blue to black hue is frequently confused with other darker pigmented lesions, including malignant melanoma.
