- muscle
fibrous benign mesenchymal tumors
- fibroma
- inflammatory fibrous hyperplasia
- inflammatory papillary hyperplasia
- pyogenic granuloma
- peripheral giant cell granuloma
- peripheral ossifying fibroma
what causes fibroma (irritation fibroma)?
collagen deposition secondary to trauma
T/F: true fibromas are neoplasms, but controversy as to whether irritation fibromas are
true
what are considered fibromas?
- frenal tag
2. retrocuspid papilla
where does fibromas affect?
buccal mucosa and tongue (but potentially any mucosal surface)
clinical features of fibroma
- smooth or slightly papillary surface
- dome-shaped
- sessile or pedunculated
- most 1.5 cm or less
- may ulcerate if traumatized
- asymptomatic unless traumatized
frental tag
small, innocuous growth easily diagnosed clinically
tx for frenal tag
none necessary
retrocuspid papilla
bilateral papular lesions on the gingiva lingual to the mandibular canines
histopathologic features of fibroma
nodular mass of dense fibrous CT
tx of fibroma
conservative excision
T/F: recurrence of fibroma is rare
true
what is inflammatory fibrous hyperplasia (IFH) also known as?
- denture epulis
- epulis fissuratum
- denture-induced fibrous hyperplasia
clinical features of IFH
- flange of ill-fitting denture
2. may have central fissure/ulcer
histopathologic features of IFH
fibrovascular CT covered by stratified squamous epithelium
tx of IFH
- conservative excision
2. remake denture
prognosis of IFH
excellent if appropriately treated
what is inflammatory papillary hyperplasia (IPH) also known as?
denture papillomatosis - may have superficial candidiasis
what causes IPH?
- ill-fitting maxillary denture
- poor denture hygiene
- wearing denture 24/7
clinical features of IPH
- numerous asymptomatic red/erythematous papules
2. central region of hard palatal mucosa
