Melanocytic nevi are subject to change with age in both clinical and histopathologic findings. In 1991, Cho et al. first reported three cases of lobulated intradermal nevi and suggested their cases represented an unusual form of regressing melanocytic nevus. Herein we report four cases of lobulated intradermal nevus and review previous literature.

Cutis verticis gyrata(CVG) is an unusual conformation of the scap characterized by the presence of folds and furrows due to thickening of the corium and the subutlneous tissue. In sccordance with etiological factor and associated findings, CVG occurs as primarary disease or secondary to a variety of local or systemic diseases. Cerebriform intradermal nevus(CIN) is a cause of CVG that can usually be recognized clinically and for a certainty histologically. We report two cases of CVG due to CIN. Not only did they have CVG due to CIN on the scalp, but also they had associated congenital nevi on the face and whole boispy, respectively.

Melanocytic nevi of the lower lip are rare benign melanocytic tumors. They can be classified in four types (junctional, compound, intradermal, blue). Among these 4 types, the intradermal type (sometimes referred to as intramucosal or subepithelial type) is the most common type. We report here on a case of intradermal nevus that developed on the lower lip of an 87-years old female patient who presented with a 0.8 cm-sized, partially crusted nodule.

Atypical junctional melanocytic hyperplasia is a rare condition with unknown etiology. It is characterized by focal atypical melanocytic proliferation limited in the basal layer. Although this lesion is difficult to separate from melanoma in situ (MIS), it could be distinguished from MIS by the lack of several features, including lateral spread, upward epidermal migration, marked cytologic atypia, finely granular "smoky" melanin pigment, mitotic figures, and a subjacent host inflammatory response. In one study, atypical junctional melanocytic hyperplasia was found in 6.2% (25/400) of otherwise normal intradermal nevi. However, to our knowledge, no case of atypical junctional melanocytic hyperplasia with intradermal nevus has ever been published in Korean dermatologic literatures. Herein, we report a rare and interesting case of atypical junctional melanocytic hyperplasia with intradermal nevus.

A 37-year-old female presented with a lobulated 2.5 x 1.5cm sized tumor with several sat ellite papules on the left lateral malleolar area for 27 years. Hiopsy specimens from hoth the lobulated lesion and the satellite lesion showed findings similar with features of intradermal nevus.

Nevus of Nanta is a melanocytic nevus with secondary ossification. Many theories involving external stimuli have been proposed to explain this rare condition; however, the origin of the ossification within the melanocytic nevus remains unknown. A 70-year-old woman presented with an asymptomatic solitary skin-colored papule with a central depression on the right malar area for one year. Histopathologic examination revealed an intradermal nevus with bone trabeculae. We herein report an interesting case of nevus of Nanta.

Nevus of Nanta is a pigmented nevus associated with secondary ossification. We describe a case of nevus of Nanta with no evidence of Albright's hereditary osteodystrophy. A 26-year-old Korean woman presented with a small asymptomatic brownish nodule on the right forehead. Histopathologic examination revealed nests of nevus cells in the dermis. Round ossification was in the base of intradermal nevus.

The intradermal nevus is composed of nevus cells which are usually referred to as the melanocytic nevi and is a form of benign cutaneous tumor. Although the intradermal nevi are common benign pigmented skin tumors, their occurrence within the external auditory canal is uncommon. The clinical and pathologic features of the intradermal nevus arising within the external auditory canal are presented, with a review of literature.
