Biology:Nevus cell
From HandWiki
Nevus cells are a variant of melanocytes.[1]:684 They are larger than typical melanocytes, do not have dendrites, and have more abundant cytoplasm with coarse granules.[2] They are usually located at the dermoepidermal junction or in the dermis of the skin. Dermal nevus cells can be further classified: type A (epithelioid) dermal nevus cells mature into type B (lymphocytoid) dermal nevus cells which mature further into type C (neuroid) dermal nevus cells, through a process involving downwards migration.[2] Nevus cells are the primary component of a melanocytic nevus.[3]
Nevus cells can also be found in lymph nodes[4] and the thymus.[5]
