differential diagnoses of pigmented skin lesions, by relative incidence and malignancy potential, including<unk>  or<unk>  pattern nevus" near top. Deep<unk>  nevus Benign<unk>  nevi can have histological characteristics resembling melanomas, often breaking most if not all of the ABCDE rules. Dermatoscopic findings of the smaller forms of benign<unk>  nevi can aid in their differentiation from other pigmented neoplasms. Microscopically,<unk>  melanocytic nevi appear similar to acquired nevi with two notable exceptions. For the<unk>  nevus, the neval cells are found deeper into the dermis. Also, the deeper nevus cells can be found along with neurovascular bundles, with both surrounding hair follicles, sebaceous glands, and subcutaneous fat. Such annexes and the Subcutaneous tissue can also be hypoplasic or, conversely, present aspects of hamartoma. Classification Giant<unk>  in newborn<unk>  melanocytic nevi may be divided into the following types: * Small-sized<unk>  is defined as having a diameter less than . * Medium-sized<unk>  is defined as having a diameter more than but less than . * Giant<unk>  (also known as "bathing trunk nevus," "garment nevus," "giant hairy nevus", and "nevus pigmentosus et pilosus") is defined by one or more large, darkly pigmented and sometimes hairy patches.
