ABSTRACT
BACKGROUND:
Juvenile hyaline fibromatosis is a sporadic hereditary disease with autosomal recessive mode of inheritance, characterized by the presence of nodules and tumours in the skin and soft tissues and gingival hyperplasia. The majority of patients are growth retarded, suffer from joint disorders, contractures, osteolytic lesions and have a positive family history. The disease most frequently occurs in children, but may be diagnosed also in adults. Since 1873, when the disease was described by Murray, only a few cases were introduced in the literature. THE AIM AND THE BASIS OF THE STUDY To present the clinical pattern of a patient diagnosed at the age of 28 and describe also the histopathological, immunohistological and electron-microscopic findings of excisions from the lesions.METHODS:
The pathologist in cooperation with clinicians from several disciplines established the diagnosis on the basis of typical histopathological picture and additional immunohistological tests not yet introduced in the literature.RESULTS:
Tumorous lesions contained hyaline structureless matrix often with chondroid or even osteoid metaplasia, calcium salts. The matrix contained numerous fibroblastoid-like cells with eosinophilic cytoplasm, oval nucleus and often pericytoplasmic halo. ELMI investigation revealed dilated cisternae of rough endoplasmic reticulum and hypertrophic Golgi apparatus. Sporadically were particles with calcium salts density detected. Immunohistochemical tests revealed the expression of vimentin, alfa1-antitrypsin and alfa1-antichymotripsin by the tumorous cells.CONCLUSION:
The authors presented an extremely sporadic childhood disease in an adult. The results are in accordance with the data from the literature. Immunohistochemical picture of "cementicles" has not yet been introduced in the available literature. (Fig. 12, Ref. 25.)
