Summary
Juvenile hyaline fibromatosis, a rare genetic disorder, was diagnosed in an adult patient. This case highlights the disease
Area of Science:
- Medical Genetics
- Dermatopathology
- Histopathology
Background:
- Juvenile hyaline fibromatosis (JHF) is a rare, autosomal recessive genetic disorder.
- Characterized by skin/soft tissue nodules, gingival hyperplasia, growth retardation, and joint issues.
- Typically presents in childhood, but diagnosis in adulthood is possible.
Observation:
- A 28-year-old patient presented with clinical manifestations of JHF.
- Histopathological, immunohistological, and electron-microscopic analyses were performed on lesion excisions.
Findings:
- Tumorous lesions showed hyaline matrix with chondroid/osteoid metaplasia and calcium deposits.
- Fibroblastoid cells with specific cytoplasmic and nuclear features were observed.
- Electron microscopy revealed dilated endoplasmic reticulum and Golgi apparatus.
- Immunohistochemistry demonstrated vimentin, alpha1-antitrypsin, and alpha1-antichymotrypsin expression.
Implications:
- Presents a rare adult case of JHF, expanding understanding of its clinical spectrum.
- Introduces novel immunohistochemical findings for JHF, potentially aiding diagnosis.
- Contributes to the limited literature on this sporadic genetic condition.
