The skin biopsy reveals an accumulation of collagen fibers with reduction in the number of elastic fibers. Cardiac anomalies may be observed. Familial cutaneous collagenoma follows an autosomal dominant mode of transmission. UMLS:C0406817 SCTID:239139000 MESH:C562925 icd11.foundation:982220551 OMIM:115250 dermis disorder
