Desmoplastic melanoma, primary – http://id.who.int/icd/entity/427778495

Desmoplastic malignant melanoma is characterised by its subtle and misleading clinical and histological morphology. For this reason diagnosis is often missed or delayed. Usually it has an innocuous clinical appearance described as an indurated discoid papule, plaque or nodule. Pigmentation is frequently absent, although a lentigo- or lentigo maligna-like discolouration adjacent to the nodule is not uncommon. Desmoplastic malignant melanoma has a high propensity for local recurrence and, although the tumour may show only minor cytological atypia, it may in fact behave aggressively.
