Dermoscopic patterns in confluent and reticulated papillomatosis: a case report
Confluent and reticulated papillomatosis (CRP) is an uncommon, progressive, distinctive dermatosis. It is characterized by persistent brown, scaly macules, papules, patches and plaques.

| description | Confluent and reticulated papillomatosis (CRP) is an uncommon, progressive, distinctive dermatosis. It is characterized by persistent brown, scaly macules, papules, patches and plaques. It appears as tinea versicolor or acanthosis nigricans resulting in delay in the diagnosis. Hence a diagnostic tool which could help to diagnose this condition is dermoscopy. We reported a 24 year old male with skin lesions on upper back, neck and shoulders. Dermoscopic examination demonstrated fissures and ridges. Whitish structures were present on the ridges which are surrounded by grayish globules. These globules were lined by brown lines at the periphery. Fissures were brown in color. Global appearance was ‘crocodile skin-like’ pattern. Ridges and furrows in dermoscopy of CRP correspond to rete ridges in the histology. Whitish structures were there around follicular ostia which represent hyperkeratosis and acanthosis of follicular epidermis. Authors also observed sparse hairs in the involved area and V-sign under dermoscopy. Hence, pathogenesis of CRP probably revolves around hair follicles. CRP demonstrates specific dermoscopic patterns which correlate well with histopathologic changes. Therefore, authors propose that these patterns would aide in the diagnosis of CRP. |
