Telangiectasias are the clinical manifestation of diverse processes affecting blood vessels. Herein we report the case of a 60-year-old man presenting long-standing asymptomatic annular telangiectatic lesions with whitish centers. The histopathologic examination revealed thickened blood dermal vessel walls in the superficial dermis showing reduplication of the basement membrane resembling cutaneous collagenous vasculopathy (CCV).

Cutaneous collagenous vasculopathy (CCV) is a rare acquired idiopathic microangiopathy characterised by the progressive development of diffuse asymptomatic telangiectasias over the skin. Histologically, the presence of a thick hyaline collagenous wall around the affected capillaries, comprising the accumulation of collagen type IV, is noted. We herein report the case of a 17-year-old Japanese boy with symmetrical patches of diffuse telangiectasias on the bilateral extremities that persisted for 10 months. Read More

Cutaneous collagenous vasculopathy (CCV) is a rare distinct idiopathic microangiopathy of the superficial cutaneous vasculature. Seven new cases are reported (6 females and 1 male) ranging in age from 42 to 85 years, with some showing unusual clinical and histopathological findings. All presented with macular telangiectases starting on the lower extremities and spreading progressively in 5 cases and were suspected to have generalized essential telangiectasia. Read More

Cutaneous collagenous vasculopathy is characterized by generalized cutaneous telangiectasia and unique microscopic and ultrastructural vascular changes, consisting of marked collagen deposition within the vascular walls of the post-capillary venules in the superficial dermis. There are only 4 previous cases described in the medical literature, all in males, mostly middle-aged. We have recently seen two female patients with clinical and histopathologic features diagnostic of cutaneous collagenous vasculopathy, indicating that it is not restricted to males. Read More
