Yu J, Wang L, Tian J, Yu X, Sun L. Imaging manifestations of juvenile hyaline fibromatosis: a case report and literature review. BJR Case Rep 2022; 8:20210167. [PMID: 36101737 PMCID: PMC9461728 DOI: 10.1259/bjrcr.20210167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 12/15/2021] [Accepted: 01/04/2022] [Indexed: 11/24/2022] Open
Abstract
Objective: Juvenile hyaline fibromatosis (JHF) is an autosomal recessive condition caused by a mutation in capillary morphogenesis gene 2 (CMG2) on chromosome 4q21. JHF is an extremely rare genetic disorder, and fewer than a hundred cases have been reported worldwide. In this case report, the clinical features, histopathological features and imaging manifestations of a case of JHF are presented. We present imaging manifestations of one case of JHF to deepen the radiologist’s understanding of this condition. The histopathological feature of JHF is hyaline degeneration involving skeletal muscle. Therefore, the lesion has a slightly high density on CT imaging, iso- or hypointense signal on T1WI and hypointense signal on T2WI. The boundary between the lesion and skeletal muscle is unclear. Methods: An 8-year-old male (Case 1) was examined in our department with a complaint of multiple masses on the head, neck and back in 2021. The boy was the only child of his parents and was delivered at 40 weeks gestation by caesarean section. His parents were non-consanguineous. Results : JHF displays multiple slowly or rapidly growing subcutaneous nodules. The imaging manifestations can reflect histopathological components, including nodular connective tissue and amorphous, partially calcified hyaline material.

Abstract
OBJECTIVES Hereditary gingival fibromatosis (HGF) is an uncommon, inherited condition with slow and progressive fibrous hyperplasia of the gingiva. Due to its association with mastication, speech, and occlusion problems, early diagnosis is important. We sought to summarize the available data regarding the epidemiology, clinical characteristics, and outcomes of children with HGF (< 18 years). METHODS A systematic literature review of the MEDLINE and Cochrane Library databases was conducted with respect to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (end-of-search date: March 1, 2019). RESULTS A total of 99 articles reporting on 146 patients were included. The mean age was 10.82 ± 3.93 years, and generalized gingival enlargement was seen in 97.16% (95% CI 92.69 to 99.14). Jaw, gingival, and teeth abnormalities; poor oral hygiene; eating; or speech difficulties were typical HGF-induced, while 60.90% had extraoral manifestations (95% CI 52.41 to 68.78). The disease was most commonly inherited in an autosomal dominant manner (88.41%, 95% CI 78.5 to 94.26), and about one-third of the patients had syndromic HGF (33.85%, 95% CI 23.50 to 46.00). Gingivectomy was performed in the majority of cases (91.15%, 95% CI 84.31 to 95.29), and recurrence was seen in 33.85% (95% CI 23.50 to 46.00). CONCLUSION HGF should be suspected in children with nodularity and gingival fibrosis, teeth abnormalities, or jaw distortion. Family history can help to establish the diagnosis. CLINICAL RELEVANCE More cases should focus on longer-term follow-up after gingivectomy as disease recurrence is not uncommon.

Abstract
Capillary morphogenesis gene 2 (CMG2/ANTXR2) is a cell surface receptor for both collagen VI and anthrax toxin. Biallelic loss-of-function mutations in CMG2 lead to a severe condition, hyaline fibromatosis syndrome (HFS). We have here dissected a network of dynamic interactions between CMG2 and various actin interactors and regulators, describing a different behavior from other extracellular matrix receptors. CMG2 binds talin, and thereby the actin cytoskeleton, only in its ligand-free state. Extracellular ligand binding leads to src-dependent talin release and recruitment of the actin cytoskeleton regulator RhoA and its effectors. These sequential interactions of CMG2 are necessary for the control of oriented cell division during fish development. Finally, we demonstrate that effective switching between talin and RhoA binding is required for the intracellular degradation of collagen VI in human fibroblasts, which explains why HFS mutations in the cytoskeleton-binding domain lead to dysregulation of extracellular matrix homeostasis.

Abstract
Hyaline fibromatosis syndrome (HFS) is the unifying term for infantile systemic hyalinosis and juvenile hyaline fibromatosis. HFS is a rare autosomal recessive disorder of the connective tissue caused by mutations in the gene for anthrax toxin receptor-2 (ANTXR2). It is characterized by abnormal growth of hyalinized fibrous tissue with cutaneous, mucosal, osteoarticular, and systemic involvement. We reviewed the 84 published cases and their molecular findings, aiming to gain insight into the clinical features, prognostic factors, and phenotype-genotype correlations. Extreme pain at minimal handling in a newborn is the presentation pattern most frequently seen in grade 4 patients (life-limiting disease). Gingival hypertrophy and subcutaneous nodules are some of the disease hallmarks. Though painful joint stiffness and contractures are almost universal, weakness and hypotonia may also be present. Causes of death are intractable diarrhea, recurrent infections, and organ failure. Median age of death of grade 4 cases is 15.0 months (p25-p75: 9.5-24.0). This review provides evidence to reinforce the previous hypothesis that missense mutations in exons 1-12 and mutations leading to a premature stop codon lead to the severe form of the disease, while missense pathogenic variants in exons 13-17 lead to the mild form of the disease. Multidisciplinary team approach is recommended.

Abstract
Juvenile hyaline fibromatosis (JHF) is a rare hereditary disease with an autosomal recessive transmission. JHF is characterized by papulonodular skin lesions, osteolytic bone lesions, flexural joint contractures, and gingival hyperplasia and usually diagnosed in infancy or early childhood. JHF is thought to be a disorder of collagen metabolism and characterized by homogenous amorphous eosinophilic material and fibrous tissue. We report the case of a 14-year-old male child with multiple papulonodular skin lesions, progressive flexion contractures of joints, and severe gingival hyperplasia, with a 10-year follow-up. Although the lesions were totally removed thrice during the last 10 years, they recurred rigorously.

Abstract
BACKGROUND Hyaline fibromatosis syndrome (HFS) is a recently introduced alternative term for two disorders that were previously known as juvenile hyaline fibromatosis (JHF) and infantile systemic hyalinosis (ISH). These two variants are secondary to mutations in the anthrax toxin receptor 2 gene (ANTXR2) located on chromosome 4q21. The main clinical features of both entities include papular and/or nodular skin lesions, gingival hyperplasia, joint contractures and osteolytic bone lesions that appear in the first few years of life, and the syndrome typically progresses with the appearance of new lesions. METHODS We describe five Lebanese patients from one family, aged between 28 and 58 years, and presenting with nodular and papular skin lesions, gingival hyperplasia, joint contractures and bone lesions. Because of the particular clinical features and the absence of a clinical diagnosis, Whole Genome Sequencing (WGS) was carried out on DNA samples from the proband and his parents. RESULTS A mutation in ANTXR2 (p. Gly116Val) that yielded a diagnosis of HFS was noted. CONCLUSIONS The main goal of this paper is to add to the knowledge related to the clinical and radiographic aspects of HFS in adulthood and to show the importance of Next-Generation Sequencing (NGS) techniques in resolving such puzzling cases.

Abstract
Juvenile hyaline fibromatosis (JHF) is a rare autosomal recessive inherited condition presenting early in life and characterized by the accumulation of hyaline-like tissue in the skin as well as various organs. Gingival overgrowth is a significant oral manifestation. This paper highlights how early and essential periodontal intervention may be necessary to improve mastication and subsequent weight gain, and to eliminate pain and improve the patient's quality of life. Here we highlight the key features of this condition and demonstrate how appropriate surgical management can have a significant impact on a patient's wellbeing. CPD/CLINICAL RELEVANCE: Juvenile hyaline fibromatosis has a significant impact on patient wellbeing and it is therefore important that clinicians are able to recognize the condition and ensure that patients receive appropriate care and management.

Abstract
Juvenile hyaline fibromatosis (JHF) and infantile systemic hyalinosis (ISH) are rare, autosomal recessive disorders of the connective tissue caused by mutations in the gene encoding the anthrax toxin receptor 2 protein (ANTXR2) located on chromosome 4q21. Characteristically, these conditions present with overlapping clinical features, such as nodules and/or pearly papules, gingival hyperplasia, flexion contractures of the joints, and osteolytic bone defects. The present report describes a pair of sibs and three other JHF/ISH patients whose diagnoses were based on typical clinical manifestations and confirmed by histopathologic analyses and/or molecular analysis. A comparison of ISH and JHF, additional thoughts about new terminology (hyaline fibromatosis syndrome) and a modified grading system are also included.

Abstract
Juvenile hyaline fibromatosis (JHF) is a rare autosomal-recessive hereditary disease, characterized by gingival hypertrophy, flexion contractures of joints, bone lesions, hyaline deposition in the extracellular spaces of the dermis and soft tissues, stunted growth, and skin lesions such as multiple nodules, tumors and pink, pearly papules. No case of JHF with a mandibular bone involvement, exists in the literature. Bone involvement in JHF is an uncommon finding and distinct solitary lesions in the calvarial bones has been reported by some authors. A 21-year-old male patient was referred to Diyarbakir Military Hospital, Department of Dental Service. Clinical findings were consistent with a solid alveolar mass in the right mandibular premolar-molar region and displaced right mandibular molar teeth. Orthopantomographic examination showed impaction of all lower right molars in a mixed radioopaque/radiolucent area. Microscopically, increased nodular connective tissue was seen under the lobulated mucosal surfaces of the resected area. The case presented here had a localized fibrous proliferation that infiltrated bone trabeculae and caused displacement of teeth. Juvenile hyaline fibromatosis should be considered in the differential diagnosis with the other intraosseous radiolucent-patchy opaque lesions of jaw bones. Based on the clinical and histopathological findings, a diagnosis of JHF was made.

Abstract
BACKGROUND A difference from the normal range in collagen profile and perivascular hyaline deposition in the dermis and gingiva has been demonstrated histopathologically in juvenile hyaline fibromatosis (JHF), which is an autosomal recessive disease. The aim of this study was to understand the mechanism of gingival overgrowth in JHF, and to observe differences in the expression of genes regulating extracellular matrix organization. METHODS Human gingival fibroblasts (GF) were obtained from individuals who have clinically healthy gingival tissue. JHF-GF were obtained from a patient who underwent a gingivectomy. Cultured fibroblast cells were examined visually using a phase contrast microscope. Total RNA from both cell types was isolated, and after biotin-deoxyuridine triphosphate (dUTP) labeling of cDNA, hybridization was performed with a pathway-specific gene expression profiling array membrane. Extracellular matrix (ECM) and adhesion molecule (AM) mRNA expressions in GF and JHF-GF were analyzed, and microarray data on genes modulating ECM remodeling were confirmed with reverse transcription-polymerase chain reaction (RT-PCR). RESULTS Cell morphology differences were observed between fibroblast types. Although type I collagen gene expression levels were almost the same, decreased type IV collagen expression was noted in JHF-GF versus GF. Decreased matrix metalloproteinase (MMP) and increased tissue inhibitor of matrix metalloproteinase (TIMP) transcripts were noted in JHF-GF versus GF. Increased fibronectin and decreased laminin mRNA expression were observed in JHF-GF when compared to GF. The present findings suggest that GF and JHF-GF differ not only morphologically but also in the expression level of ECM and AM genes involving connective tissue turnover and remodeling. CONCLUSIONS Results from these analyses may be helpful to clarify the nature of overgrowth mechanisms, especially regarding enzymes and their inhibitors. This information is important in understanding the remodeling of ECM. The gingival overgrowth that is observed in JHF patients may be explained by a decreased level of MMPs and increased blockage of MMPs with TIMPs.
