Juvenile hyaline fibromatosis in siblings.

Juvenile hyaline fibromatosis (JHF) is a rare, autosomal recessively inherited disorder. We report two siblings with multiple large tumors on the scalp, translucent papules on the nape of the neck, hypertrophic gingiva, and severe flexural contractures of large joints. The histopathology from the skin lesions showed features characteristic of juvenile hyaline fibromatosis. The cases are being reported on account of the extreme rarity of the condition.
