Solitary asymptomatic plaque over the back: A clinicopathological challenge

A 31-year-old Indian male presented with complaints of an asymptomatic, slow-growing solitary plaque over the upper back for 1 year [Figure 1a].ere were no similar lesions elsewhere.e patient gave no history of prior treatment taken for these complaints.Clinical examination revealed a solitary well-defined porcelain white plaque over the upper back, measuring about 2.5 × 2.5 cm, with a rolled-out border [Figure 1b].e plaque had an atrophic surface with telangiectasia and a few areas of hemorrhage.Dermoscopic examination revealed white structureless areas, linear vessels, hemorrhages, perifollicular scaling, and a single comedo-like opening [Figure 2].A punch biopsy was taken from the lesion for confirmation of the diagnosis.
