No treatment is needed for cutis marmorata telangiectatica congenita (CMTC) unless associated anomalies (eg, glaucoma, hypospadias, syndactyly, multicystic renal disease, cardiac malformation, limb asymmetry) require treatment.
The association between retinal detachment and cutis marmorata is salient, as laser photocoagulation may effectively treat the associated retinal detachment. 
Consultation with an orthopedist and/or neurosurgeon may be necessary for evaluation of associated anomalies (eg, limb or cranial defects). Limb-length discrepancy and asymmetry, common in this disorder, may prompt orthopedic referral. 
Consultation with an ophthalmologist may be necessary because glaucoma has been reported in association with cutis marmorata telangiectatica congenita. However, all of the patients with glaucoma had periocular skin changes around the affected eye. Therefore, ophthalmologic evaluation is probably only indicated in this setting.
Hemangiomas and lymphangiomas have been seen in association with cutis marmorata telangiectatica congenita. Diffuse dermal angiomatosis may also arise in cutis marmorata telangiectatica congenita.  The former is a variant of reactive angioendotheliomatosis, often evident clinically as painful, violaceous, nonhealing erosions or ulcers. It is characterized histologically by diffuse endothelial cell hyperplasia within the reticular dermis rather than the intravascular proliferation typical of reactive angiomatosis.
