Workup

Laboratory Studies

Physical examination helps in diagnosing cutis marmorata telangiectatica congenita (CMTC).

Imaging Studies

Imaging studies are indicated only for the evaluation of other suspected congenital anomalies. Such studies are specifically performed according to the clinician's suspicion.

Other Tests

This cutaneous vascular disorder may occasional have ocular involvement. Bilateral peripheral retinal vascular abnormalities and retinal nonperfusion on fluorescein angiography without retinal detachment were documented in one patient. [37] Congenital glaucoma, suprachoroidal hemorrhage, and bilateral total retinal detachments resulting in secondary neovascular glaucoma have been described rarely. [38]

Histologic Findings

A skin biopsy is not necessary in cutis marmorata telangiectatica congenita (CMTC) because the histologic findings are nonspecific and nondiagnostic. Microscopic findings include dilated capillaries in the deeper dermis, swollen endothelial cells, and sometimes dilated veins or venous lakes.
