Nodular melanoma, light micrograph. Nodular melanoma (NM) accounts for 3-4% of all melanoma cases. It occurs in a relatively younger age group (5th or 6th decades) than other melanoma subtypes and is of shorter duration. It appears as a smooth firm elevated nodule or a polypoid mass covered by epidermis. The colour ranges from tan (amelanotic variants), brown, blue to black. The atypical melanocytes are arranged in infiltrating nests and show moderate cytologic atypia. | |
