Cutaneous collagenous vasculopathy (CCV) is a rare benign microangiopathy of the superficial dermal vessels. Clinically, it is characterized by widespread, asymptomatic development of cutaneous telangiectasia in the absence of systemic symptoms. Morphologically, it most resembles generalized essential telangiectasia and other telangiectatic syndromes such as telangiectasia macularis eruptiva perstans (TMEP), ataxia telangiectasia, and hereditary hemorrhagic telangiectasia. It is distinctive in its histology, showing characteristic dilated thick-walled blood vessels in the superficial dermis. The thickened walls of these superficial dermal blood vessels demonstrate reduplication of the basement membrane on PAS staining. We report a 63-year-old man with CCV with this condition for 20 years, starting in 1996. He was diagnosed in the past as having essential telangiectasia. The development of the telangectasias occurred after coronary artery bypass grafting, also performed in 1996. This case not only demonstrates the characteristic clinical and histologic findings, but also suggests a possible mechanism. Moreover, it illustrates that cases of generalized essential telangiectasia may in fact be CCV that are misclassified.
