The solitary nodular form of nevus lipomatosus cutaneus superficialis is uncommon. The site in the 21 cases reported in the literature was the upper thigh in eight cases,1-3 the buttock in seven cases,1-3 the lower back in two cases,1 and the axilla,1 arm,1 ear,4 and scalp5 in one case each. There is no apparent sex predilection for this condition. The age when the lesion was first noted was available for 16 patients, and it varied from 195 to 641 years, including two cases that occurred in the fourth decade and four cases each that occurred in the third, fifth, and sixth decades.1,3 The clinical diagnosis was of a variety of benign lesions, most commonly nevocellular nevus and fibroepithelial papilloma.
