- M-CM syndrome
Megalencephaly-capillary malformation syndrome (MCAP), formerly known as macrocephaly-capillary malformation, is a rare, complex disorder involving the skin, connective tissue, brain and other organs that is usually present at birth. Affected individuals have a disproportionately large head and capillary malformations on the skin of the midline face, trunk and limbs. These capillary malformations often show a lacy or reticulated pattern (resembling a net or web, and are sometimes termed "cutis marmorata"). Most children with MCAP have an enlarged brain (or megalencephaly), in addition to other findings on brain MRI associated with neurologic problems.
Multiple terms have been used in the past for this syndrome. The earliest one was macrocephaly-cutis marmorata telangiectatica congenita (M-CMTC) because the vascular lesions were mistakenly believed to be consistent with CMTC. However, careful examination of the skin in these children revealed that the vascular lesions are not CMTC but rather capillary malformations (described below), and so the syndrome was accurately renamed to "macrocephaly-capillary malformation syndrome" (or M-CM). Recently, the name was modified from this latter term to "megalencephaly-capillary malformation" (or MCAP, in short) because the term "macrocephaly" refers to a large head due various causes, whereas "megalencephaly" is a more specific and accurate term that refers to the truly enlarged brain present in this syndrome.
