Cutis Marmorata Telangiectatica Congenita Associated with Hemiatrophy

Area of Science:

• Dermatology
• Vascular Malformations
• Pediatric Medicine

Background:

• Cutis marmorata telangiectatica congenita (CMTC) is a rare congenital vascular disorder.
• It is characterized by a bluish-purple reticulated network on the skin, telangiectasias, and prominent veins present at birth.

Observation:

• Affected skin areas may exhibit normal appearance, erythema, atrophy, or ulceration.
• Focal cutaneous and subcutaneous atrophy can lead to body asymmetry.
• Extensive atrophy causing hemiatrophy of an entire limb is exceptionally rare.

Findings:

• This study adds two new cases of CMTC to the existing literature.
• A review identified only eight previously documented cases of CMTC with severe limb atrophy.

Implications:

• Highlights the spectrum of CMTC, including rare but severe manifestations like limb hemiatrophy.
• Emphasizes the importance of recognizing CMTC for appropriate clinical management and monitoring.
• Contributes to the understanding of the natural history and potential complications of CMTC.
