Case 1 was a 58-year-old man presenting with a dome-shaped elastic-soft nodule measuring 24 × 18 mm on the left buttock, which had developed five years previously. Case 2 was a 63-year-old woman with an elastic-soft subcutaneous nodule (18 × 22 mm) on the posterior side of the right thigh, which she had first noticed five years before. Case 3 was a 79-year-old man with an elastic-soft subcutaneous nodule (17 × 10 mm) on the lateral side of his left thigh, which he had become aware of four years previously. In all three cases, adipose tissue proliferation was observed between the dermal collagen fibers. Nevus lipomatosus cutaneous superficialis (NLCS) was diagnosed, with lipoma or soft fibroma considered in the differential diagnosis. All three nodules were excised. In case 3, the signal was not suppressed on magnetic resonance imaging (MRI) with fat-suppressed T1-weighted images. Since the excisional design for cases of NLCS is different from that of lipoma, MRI was considered useful in the preoperative diagnosis.
