Description : Hyaline fibromatosis syndrome is an autosomal recessive condition characterized by
abnormal growth of hyalinized fibrous tissue usually affecting subcutaneous regions
on the scalp, ears, neck, face, hands, and feet. The lesions appear as pearly papules
or fleshy nodules. The severity is variable. Some individuals present in infancy and
have additional visceral or systemic involvement, which can lead to early death. These
patients may show intractable diarrhea and increased susceptibility to infection.
Other patients have later onset of a milder disorder affecting only the face and digits.
Additional features include gingival hypertrophy, progressive joint contractures resulting
in severe limitation of mobility, osteopenia, and osteoporosis. Histologic analysis
of skin lesions shows proliferation of spindle-shaped cells forming strands in a homogeneous
and hyaline eosinophilic extracellular material in the dermis (summary by Denadai
et al., 2012).;
Inheritance : Autosomal recessive;
