A 21-year-old male presented with multiple asymptomatic hypopigmented lesions over the back and front of trunk, which have been persisting unaltered as regards their physical appearance or number since he first developed these at 5 years of age. There was no history of any other skin abnormalities before the age of 5 or any systemic complaints. He reported no significant family history. General physical examination revealed no abnormality. Cardiovascular examination and electrocardiogram were within normal limits. Dermatological examination of the trunk revealed multiple pale white, fibrotic, rubbery, non-tender papules and nodules ranging from 5 mm to 1 cm in diameter with highest concentration over the lower back [Figure 1]a and b. There was no evidence of lesions elsewhere on the body. Histopathological examination of the papule revealed areas with thick and haphazardly-oriented collagen bundles within the reticular dermis [Figure 2]. The collagen was strongly stained with Masson trichrome stain showing an intense blue-green color [Figure 3]. The Van Gieson stain for elastin showed few fragmented interspersed elastin fibers.
