Atypical Junctional Melanocytic Proliferation Definition

Atypical Junctional Melanocytic Proliferation Definition. The term dysplastic naevus is given to the histological. “atypical junctional melanocytic hyperplasia” (ajmh) is a histological conceptual diagnosis that is made when the proliferation is “worse” than simple lentiginous melanocytic hyperplasia of a junctional or dysplastic nevus, but does not satisfy criteria for melanoma in situ.

The doctor basically said, it is an atypical mole and cells that are changing and we're lucky to have caught it now. The histological term, junctional melanocytic hyperplasia (jmh), refers to the proliferation of single melanocytes along the dermal epidermal junction that is the basal layer where normal melanocytes reside. The five visual characteristics used to identify an atypical melanocytic lesion are the same as the characteristics used to identify signs of invasive melanoma.

Atypical melanocytic naevi (amn) are skin lesions whose clinical and histologic features sit somewhere on the proliferative continuum from a common mole to a melanoma, although they rarely progress to melanoma. Proliferation of melanocytes showing nuclear atypicality, especially as scattered single cells high in the epidermis;

In contrast to melanoma in situ, exhibits only focal confluence at dermoepidermal junction, has limited pagetoid spread and involves only upper hair follicle. Lentiginous melanoma is a proliferation of malignant pigment cells (melanocytes) along the basal layer of the epidermis.
