Juvenile hyaline fibromatosis - Skin in Infant/Neonate
Cutaneous lesions are asymptomatic and slow growing, presenting as pink papules or nodules, commonly on the head, back, and knees. Gingival hypertrophy may be severe enough to interfere with feeding, leading to malnutrition as well as recurrent infections. The most debilitating features are the progressively painful joint contractures, often of the knees, elbows, fingers, and hip joints.
Patients do not have systemic involvement, but this progressive disabling disorder causes most adolescent and adults to become bedridden, with most surviving only to the fourth decade.
