Asymptomatic telangiectatic macules on the trunk and proximal extremities

Abstract

Cutaneous collagenous vasculopathy is a rare microangiopathy that presents with asymptomatic telangiectasias and distinct histopathological features, including hyaline material deposition in vessel walls. Diagnosis requires biopsy and differentiation from other telangiectatic disorders. Current treatment options are limited, but increased awareness may improve recognition and management of this rare condition. Herein, we describe an unusual presentation of cutaneous collagenous vasculopathy as asymptomatic, pink, mat-like telangiectatic macules on the trunk and proximal extremities of a 62-year-old woman. Histopathologic evaluation revealed dilated superficial dermal vessels with hyaline thickening of the vessel walls, consistent with a diagnosis of cutaneous collagenous vasculopathy.
