Murray [1] in 1873 described the lesion as molluscum fibrosum which was a synonym used for neuromatosis in children. Synonyms include systemic hyalinosis and disseminated painful fibromatosis. Recently used term juvenile hyaline fibromatosis, was coined by Kitano et al. ,[2] in 1969. Juvenile hyaline fibromatosis (JHF) is characterized by papulo-nodular skin lesions, soft tissue masses, joint contractures, gingival hypertrophy, and osteolytic bone lesions. [3],[4],[5] The accumulation of an amorphous, hyaline material is typical in the skin and the other organs. [3],[4],[5] Only 70 cases have been described in the literature.

Our case was that of a six-year-old child born of non-consanguineous marriage, admitted for multiple, progressively increasing swellings over face, back and scalp since childhood [Figure 1]. No skeletal abnormality was seen. Systemic examination was unremarkable. With a clinical diagnosis of multiple lipomatosis, he underwent surgical intervention. We received multiple well circumscribed, soft to firm, grey white masses largest measuring 3.5 × 0.5 cm. Cut section showed uniform homogenous appearance [Figure 2].

Histopathological examination showed a hypocellular lesion with spindle-shaped cells embedded in abundant homogenous, amorphous, eosinophilic, hyaline [Figure 3], periodic acid schiff (PAS) positive diastase resistant material. Many cells had vacuolated cytoplasm with nuclei lying in lacunae giving it a pseudochondroid appearance [Figure 4]. We rendered a diagnosis of juvenile hyaline fibromatosis. Panel of IHC showed vimentin positive [Figure 5], smooth muscle actin (SMA) negative, and S-100 negative, which confirmed our diagnosis.

   Discussion Top

Family history of consanguineous marriage is significant. [3] Its onset is in infancy or early childhood with a range of two to five years. The most commonly affected sites are the nose, chin, ears, scalp, back, and knees. [4] Our index case was six-year-old lad, born of a non-consanguineous marriage and had multiple subcutaneous nodules with no skeletal abnormality. Light microscopic examination of skin lesions characteristically show paucity of cells and abundance of a homogenous, amorphous, eosinophilic extracellular matrix in which spindle-shaped cells are embedded. [3],[4],[5] Many cells show ghost cell/pseudochondroid appearance. Our index case showed similar histological picture. Osteoclast-like giant cells and calcification with psammoma bodies can be noted. Early lesions are cellular with little matrix, whereas older lesions show prominent ground substance with less cellular areas. [3],[4],[5] Immunohistochemically, the spindle-shaped cells are vimentin-positive but negative for alpha-smooth muscle actin and S-100 protein, and the hyaline ground substance is positive for type I and type III collagen but negative for type II and type IV collagen and tenascin. [3],[4],[5] Immunohistochemistry (IHC) confirmed our diagnosis. Infantile systemic hyalinosis shows similar histological features with a varying clinical picture. Some authors have stated that both represent two ends of spectrum. Infantile myofibromatosis is other close differential and differences between these three conditions are tabulated in [Table 1].

Although mode of treatment is surgical excision, prognosis is determined by number, size, location, and degree of functional impairment. Local recurrence rate is high. [5] A single case showed an association of squamous cell carcinoma. There is no follow-up of our index case till date.
