Case 1Juvenile hyaline fibromatosis and infantile systemic hyalinosis are two rare autosomal recessive diseases, linked to mutations in the gene encoding type 2 capillary morphogenesis protein. They are characterized by the accumulation of hyaline deposits in the skin and joints in the first disease, and in the skin, joints, and viscera in the second. We report a case of a child with juvenile hyaline fibromatosis due to a mutation in the ANTXR2 gene.Case reportA 2-year-old child gradually developed [...]
