Connective Tissue Lesions Flashcards
Most common benign tumor of oral cavity
Fibroma
Reactive fibrous hyperplasia due to local irritating factor
Fibroma
Painless, smooth, firm, pink nodules 1.5 cm or less, mostly sessile, buccal mucosa near occlusal plane
Fibroma
Denture induced fibrous hyperplasia related to ill fitting denture
Epulis Fissuratum
Single or multiple fold of hyperplastic tissue in alveolar vestibule surrounding overextended denture flange
Denture Epulis
Common reactive hyperplastic mass found exclusively on gingiva
Peripheral fibroma
Reactive gingival growth contains calcified islands within fibrous tissue, bone, cementum like material or dystrophic calcification
Peripheral ossifying fibroma
Odontogenic epithelium within the connective tissue
Peripheral Odontogenic Fibroma
Increase in bulk of gingiva, interdental papilla, rolled, blunted, soft and spongy to firm and dense, abundance of collagen and fibroblasts
Generalized Gingival Hyperplasia
Benign vascular smooth muscle tumor
Leiomyoma
Malignant neoplasm of smooth muscle mostly in uterine wall and GI tract
Leiomyosarcoma
Enlarged ulcerated mass, painful
Leiomyosarcoma
Benign skeletal muscle tumor
Rhabdomyoma
Uncommon benign soft tissue lesion hight occurance in oral cavity
Granular cell tumor/ myoblastoma
Schwann cells, dorsal surface of tongue, pink to yellow sessile nodules
Granular cell tumor
Pseudoepitheliomatous hyperplasia
Granular cell myoblastoma
Uncommon soft tissue tumor exclusively on alveolar ridge of newborns, mostly females, mostly max ridge
Congenital epulis of the newborn
Autoimmune, unknown cause, dense collagen 1 and 3 deposited in great amounts
Systemic sclerosis
Sclerosis only on skin and not the internal organs
Systemic sclerosis
Sclerosis on skin and multiple internal organs
Diffuse scleroderma
Raynaud’s phenomena- vasoconstriction triggered by emotional distress or exposure to cold
Systemic sclerosis
Mask like face, claw like fingers, mouse face
Systemic sclerosis
Microstomia, purse string appearance, diffuse widening of PDL, mand bone resorption
Systemic sclerosis
Benign tumor of fat
Lipoma
Reactive proliferation after trauma to peripheral nerve damage, mental foramen area, tongue, lower lip, painful on digital pressure
Traumatic Neuroma
Benign neoplasm, proliferation of schwann cells of neurilemma
Schwannoma
Antoni A- verocay bodies, Antoni B
Schwannoma
Most common benign peripheral nerve neoplasm
Neurofibroma
Schwann cells & perineural fibroblasts
Neurofibroma
Most common type if neurofibromatosis
Von Recklinghausen’s disease of skin/ neurofibromatosis type I
Multiple neurofibromas of oral cavity & skin, cafe-au-lait spots, iris freckling, lisch nodules, axillary freckling, crowe sign
Von Recklinghausen’s disease of skin
Mucocutaneous neuromas, oral mucosal neuromas, complication medullary carcinoma of thyroid
Multiple endocrine neoplasia(MEN)
Benign hamartomas of lymphatic vessels, head & neck, anterior 2/3 of tongue, macroglossia, diffuse soft fluctuant pebbly surface
Lymphangioma
Cystic hygroma, neck, life threatening
Macrocystic lymphangioma
Benign reactive proliferation of superficial fascia
Nodular fasciitis
