Nevus Lipomatosus Cutaneous Superficialis: A Case Report and Literature Review

IntroductionNevus lipomatosus cutaneous superficialis (NLCS) is uncommon and can be encountered in various medical specialties. In this study, we report a rare case of solitary pedunculated nevus lipomatosus cutaneous superficialis in a middle-aged female patient and highlight its clinical and histopathological features.Case PresentationA 43-year-old Malaysian female patient presented to our center with a 2-cm long and 1-cm wide solitary, flesh-colored nodule over the anterolateral aspect of her thigh. Excisional biopsy was performed, and the histopathology report showed NLCS. There are three types of NLCS, namely the solitary, multiple, and generalized forms. The etiology of NLCS is usually idiopathic, with no gender or familial preponderance. NLCS is usually misdiagnosed and should be differentiated from nevus sebaceous, connective tissue nevus, neurofibroma, lymphangioma, hemangioma, and focal dermal hypoplasia (also known as Goltz syndrome).ConclusionsIn conclusion, NLCS is rare and benign condition, which should be differentiated from other malignant skin conditions as it is commonly misdiagnosed. Therefore, physicians and surgeons should be aware of its clinical and histopathological features.
