Cutis Marmorata Telangiectatica Congenita: Clinical Image

Abstract

Congenital cutis marmorata telangiectatica (CMTC) is a rare cutaneous vascular malformation characterized by areas of skin showing a reticulated erythematous-violaceous pattern, usually localized and present at birth or shortly thereafter. Diagnosis is primarily clinical, with findings of flat or slightly depressed reticulated erythema with a marbled appearance ranging from pale red to deep violet. The lesions blanch on diascopy, become more pronounced with cold exposure, but do not resolve with warmth, which helps differentiate this condition from physiologic cutis marmorata. The most frequent sites of involvement are the lower extremities, followed by the trunk and face. Lesions are typically localized and asymmetrically distributed. Histopathological findings are nonspecific and of limited utility in the differential diagnosis. The most commonly observed features include dilation of dermal capillaries and venules, making it indistinguishable from other vascular malformations.
