Infantile systemic hyalinosis (ISH) is a rare, progressive autosomal recessive disease, which is usually fatal by the age of 2 years. Clinical onset typically occurs within the first few weeks of life. The disease is characterized by joint contractures, osteopenia, failure to thrive, gingival hypertrophy, diarrhea, protein-losing enteropathy, and frequent infections. Dermatologic manifestations include thickened skin, hyperpigmentation, perianal nodules, and facial papules. Histopathology shows hyaline deposits in the dermis and visceral organs. We describe a patient with ISH confirmed by clinical and histopathologic findings, as well as DNA sequence analysis, which revealed a novel homozygous T118K mutation in the CMG2 gene.
