Nevus Lipomatosus Superficialis With Dilated Hair Follicles

The document described two cases of nevus lipomatosus superficialis (NLS), a rare skin anomaly, presenting with unique features of dilated hair follicles. Patient 1, a 20-year-old man, had soft papules and nodules on his buttock and waist, with histopathology revealing ectopic adipose tissue and cystically dilated hair follicles. Patient 2, a 21-year-old man, had a flesh-colored plaque on his back, with similar histopathologic findings. These cases highlighted the importance of differentiating NLS with dilated hair follicles from nevus comedonicus, as the latter can be associated with systemic abnormalities. Accurate diagnosis through histopathology was emphasized due to the clinical variability of NLS.
