Insights
Juvenile hyaline fibromatosis (JHF) is a rare genetic disorder causing tumors and lesions. This case highlights management of gingival hyperplasia in a 9-year-old girl with JHF.
Area of Science:
- Genetics
- Dermatology
- Pediatrics
Background:
- Juvenile hyaline fibromatosis (JHF) is an extremely rare autosomal recessive genetic disorder.
- Characterized by cutaneous tumors, papulonodular lesions, joint contractures, gingival hyperplasia, and osteolytic bone lesions.
- Typically diagnosed in infants and children under 5 years old.
Observation:
- A case report of a 9-year-old girl diagnosed with JHF.
- The patient presented with severe gingival hyperplasia, nasal enlargement, mild osteoporosis, and multiple papulonodular skin lesions.
- Her two brothers (aged 7 and 13) also had a JHF diagnosis.
Findings:
- Gingivectomy followed by meticulous oral hygiene led to sustained resolution of gingival hyperplasia.
- Recurrence of skin lesions and persistent nasal overgrowth were observed.
- The characteristic lesions consist of fibrous tissue and amorphous hyaline material.
Implications:
- Effective management of gingival hyperplasia in JHF is achievable with appropriate interventions.
- Highlights the chronic and recurrent nature of skin lesions and skeletal abnormalities in JHF.
- Emphasizes the importance of long-term monitoring and multidisciplinary care for patients with JHF.
Abstract:
Juvenile hyaline fibromatosis (JHF) is an extremely rare hereditary genetic disease of autosomal recessive transmission that is characterized by large cutaneous tumors commonly involving the scalp, papulonodular skin lesions, flexural joint contractures, gingival hyperplasia, and osteolytic bone lesions. JHF is usually diagnosed in young infants and in children younger than 5 years, and the lesions characteristic of this disorder consist of fibrous tissue and homogenous amorphous eosinophilic hyaline material. We report the case of a 9-year-old girl with severe gingival hyperplasia, nasal enlargement, mild osteoporosis, and multiple papulonodular skin lesions. Her two brothers (7 and 13 years of age, respectively) were also diagnosed as having JHF. In the patient described in this report, the maintenance of oral hygiene after gingivectomy enabled the continued resolution of gingival hyperplasia, although skin lesions recurred and nasal overgrowth persisted.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
