Solitary Plaque Nevus Lipomatosus Cutaneous Superficialis on the Face / 대한피부과학회지

Nevus lipomatosus cutaneous superficialis (NLCS) is an uncommon form of connective tissue nevus, which is manifested principally as the deposition of fatty tissue in the dermis. Lesions almost always arise unilaterally on the thigh or buttock. Although NLCS can affect any region of the skin, only five cases of NLCS on face have been reported. A 48-year-old female presented with a skin-colored, 1 cm sized, soft and edematous plaque on the right malar area. The histopathologic findings showed scattered ectopic fat lobules between collagen fibers in the mid to deep dermis. We herein reported a case of solitary and plaque-shaped NLCS on the malar area.

Nipple Shaped Solitary Nevus Lipomatosus Cutaneous Superficialis: Report of a Case and a Review of the Korean Literatures / 대한피부과학회지

Nevus lipomatosus cutaneous superficialis is a fairly uncommon form of connective tissue disorder, and this is characterized by the ectopic deposition of fat lobules in the dermis. There are two clinical variants: the multiple and solitary types. Particularly for the case of the solitary forms, it seems preferable to regard them instead as pedunculated lipofibromas. We report here on a case of a nipple shaped solitary nevus lipomatosus cutaneous superficialis, and we also review the Korean cases. Till now, 22 cases in Koreahave been reported as a solitary nevus lipomatosus cutaneous superficialis and a pedunculated lipofibroma, or both. The review of the Korean cases revealed that solitary nevus lipomatosus cutaneous superficialis almost always exhibits a single skin-colored dome shaped or pedunculated nodule on the thigh and buttock, as well as on the non-girdle area after the 4th decade, and it has no histopathological difference from the multiple forms.

Solitary Nevus Lipomatosus Cutaneous Superficialis on the Forehead Presenting as a Soft Edematous Plaque / 대한피부과학회지

Nevus lipomatosus cutaneous superficialis(NLCS) is a rare nevoid anomaly characterized by ectopic adipose tissue in the dermis. In this disease, two clinical types are distinguished: the classical type consisting of grouped papules and nodules, which are distributed linearly over the buttocks or upper thighs, and solitary type consisting of solitary pedunculated or dome-shape nodule without predilection. The solitary type is much rarer than the classical type. Unlike the classical type, the solitary type, especially on the forehead, is often mistaken for another type of benign tumor such as a lipoma. The author experienced a case of solitary NLCS, a 56-year-old female who had flesh, soft and edematous plaque on the forehead with soft surface during 13 months. Histological examination showed ectopic mature adipocytes in the dermis. The lesion was treated by surgical excision.
