Atypical melanocytic proliferations may also be seen in the nail unit and represent a separate diagnostic and therapeutic dilemma. Nomenclature Key Points Multiple descriptive terms representing histologically ambiguous melanocytic proliferations are used to refer to lesions that do not clearly fit into a “benign” or “malignant” category (Table 1).

Melanocytic nevi are benign neoplasms or hamartomas composed of melanocytes, the pigment-producing cells that constitutively colonize the epidermis.

Atypical intraepidermal melanocytic proliferation (AIMP) is a descriptive histopathologic term commonly used in these cases to denote morphology sharing some features with melanoma but failing to meet criteria of a definitive benign or malignant diagnosis. 1.

Melanocytic hyperplasia (or epidermal melanocytosis) consists in an increased number of melanocytes along the epidermal basal layer. Melanocytes are also more evident for their large size, large nucleus and prominent cytoplasm.

An intradermal nevus (also called an intradermal melanocytic nevus) is simply a classic mole or birthmark. It typically appears as an elevated, dome-shaped bump on the surface of the skin.
(ay-TIH-pih-kul mole) A type of mole that looks different from a common mole. Several different types of moles are called atypical. Atypical moles are often larger than common moles and have regular or ragged or blurred borders that are not easy to see.

CPT code 17111 should be reported with one unit of service for removal of benign lesions other than skin tags or cutaneous vascular lesions, representing 15 or more.
A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere.
All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm. Morphology [Histology] Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, ...
The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes. Primary malignant neoplasms overlapping site boundaries.

A benign growth on the skin (usually tan, brown, or flesh-colored) that contain s a cluster of melanocytes and surrounding supportive tissue. A neoplasm composed of melanocytes that usually appears as a dark spot on the skin. A nevus characterised by the presence of excessive pigment. A nevus containing melanin.

Atypical Melanocytic lesions are irregular moles and skin spots that require further examination. The five visual characteristics used to identify an atypical melanocytic lesion are the same as the characteristics used to identify signs of invasive melanoma. These are called the ABCDE’s of melanoma.
Atypical Melanocytic lesions are largely influenced by genetics. Still, SCARS Center skin cancer specialists promote skin cancer awareness and sun safety as your best form of protection against skin cancer.

Atypical Melanocytes. Atypical melanocytic lesions are also known as dysplastic nevus or dysplastic mole, atypical mole, or atypical melanocytic hyperplasia. Mole and nevus are synonymous. By definition these lesions are benign. However, since this terminology is based on either a visual inspection or a partial biopsy of the lesion, ...
