Chapter 032. Oral Manifestations of Disease (Part 3) Diseases of the Oral Mucosa Infection Most oral mucosal diseases involve microorganisms (Table 32-1). Table 32- 1 Vesicular, Bullous, or Ulcerative Lesions of the Oral Mucosa Condition Usual Location Clinical Features Course Viral Diseases Primary acute herpetic gingivostomatitis [herpes simplex virus (HSV) type 1, rarely type 2] Lip and oral mucosa (buccal, gingival, lingual mucosa) Labial vesicles that rupture and crust, and intraoral vesicles tha t quickly ulcerate; extremely painful; acute gingivitis, fever, malaise, foul odor, and cervical lymphadenopathy; occurs primarily in infants, children, and young adults Heals spontaneously in 10– 14 days. Unless secondarily infected, lesions lasting >3 wee ks are not due to primary HSV infection. Recurrent herpes labialis Mucocutane ous junction of lip, perioral skin Eruption of groups of vesicles that may coalesce, then rupture and Lasts about 1 week, but condition may be prolonged if secondarily infected. crust; painful to pressure or spicy foods If severe, topical or oral antiviral may reduce healing time. Recurrent intraoral herpes simplex Palate and gingiva Small vesicles on keratinized epithelium that rupture and coalesce; painful Heals spontaneously i n about 1 week. If severe, topical or oral antiviral may reduce healing time. Chickenpox (varicella-zoster virus) Gingiva and oral mucosa Skin lesions may be accompanied by small vesicles on oral mucosa that rupture to form shallow ulcers; may coalesce to form large bullous lesions that Lesions heal spontaneously within 2 weeks. ulcerate; mucosa may have generalized erythema Herpes zoster (reactivation of varicella- zoster virus) Cheek, tongue, gingiva, or palate Unilateral vesicular eruptions and ulcerati on in linear pattern following sensory distribution of trigeminal nerve or one of its branches Gradual healing without scarring unless secondarily infected; postherpetic neuralgia is common. Oral acyclovir, famcyclovir, or valacyclovir reduce healing time and postherpetic neuralgia Infectious mononucleosis (Epstein-Barr Oral mucosa Fatigue, sore throat, malaise, fever, and Oral lesions disappear during convalescence; no virus) cervical lymphadenopathy; numerous small ulcers usually appear several days before lymphadenopathy; gingival bleeding and multip le petechiae at junction of hard and soft palates treatment though glucocorticoids indicated if tonsillar swelling compromises airway Herpangina (coxsackievirus A; also possibly coxsackie B and echovirus) Or al mucosa, pharynx, tongue Sudden onset of fever, sore throat, and oropharyngeal vesicles, usually in children under 4 years, during summer months; Incubation period 2– 9 days; fever for 1– 4 days; recovery uneventful diffuse pharyngeal congestion and vesicles (1– 2 mm), grayish-white surrounded by red areola; vesicles enlarg e and ulcerate Hand, foot, and mouth disease (coxsackievirus A16 most common) Oral mucosa, pharynx, palms, and soles Fever, malaise, headache with oropharyngeal vesicles that become painf ul, shallow ulcers; highly infectious; usually affects children under age 10 Incubation period 2– 18 days; lesions heal spontaneously in 2– 4 weeks Primary Gingiva, Acute Followed by HIV infection palate, and pharynx gingivitis and oropharyngeal ulceration, associated with febrile illness resembling mononucleosis and including lymphadenopathy HIV seroconversion, asymptomatic HIV infection, and usually ultimately by HIV disease Bacterial or Fungal Diseases Acute necrotizing ulcerative gingivitis ("trench mo uth," Vincent's infection) Gingiva Painful, bleeding gingiva characterized by necrosis and ulceration of gingival papillae and margins plus lymphadenopathy and foul odor Debridement and diluted (1:3) peroxide lavage provide relief within 24 h; antibiotics in acutely ill patients; relapse may occur Prenatal (congenital) syphilis Palate, jaws, tongue, and teeth Gummatous involvement of palate, jaws, and facial bones; Hutchinson's incisors, mulberry molars, glossitis, mucous patches, and fissures on corner of mouth Tooth deformities in permanent dentition irreversible Primary syphilis (chancre) Lesion appears where organism enters body; may occur on lips, tongue, or tonsillar area Small papule developing rapidly into a large, painless ulcer with indurated bor der; unilateral lymphadenopathy; chancre and lymph nodes containing spirochetes; Healing of chancre in 1– 2 months, followed by secondary syphilis in 6–8 weeks serologic tests positive by third to fourth weeks Secondary syphilis Oral mucosa frequently invo lved with mucous patches, primarily on palate, also at commissures of mouth Maculopapu lar lesions of oral mucosa, 5– 10 mm in diameter with central ulceration covered by grayish membrane; eruptions occurring on various mucosal surfaces and skin accompanied by fever, malaise, and sore throat Lesions may persist from several weeks to a year Tertiary syphilis Palate and tongue Gummatous infiltration of palate or tongue Gumma may destroy palate, causing complete followed by ulceration and fibrosis; atrophy of tongue papillae produces characteristic bal d tongue and glossitis perforation Gonorrhea Lesions may occur in mouth at site of inoculation or secondarily by hematogenous spread from a primary focus elsewhere Most pharyngeal infection is asymptomatic; may p roduce burning or itching sensation; oropharynx and tonsils may be ulcerated and erythematous; saliva viscous and fetid More difficult to eradicate than urogenital infection, though pharyngitis usually resolves with appropriate antimicrobial treatment [...]... severe signs of toxicity Pemphigus vulgaris Oral mucosa Usually and skin; sites of (>70%) With repeated presents occurrence of bullae, mechanical trauma with oral lesions; toxicity may lead to (soft/hard palate, fragile, frenulum, lips, bullae buccal mucosa) ruptured cachexia, and and death within 2 ulcerated areas; oral years; mostly planus Oral mucosa and skin often in controllable with oral older...
