    Study Notes

    Syphilis: Clinical Stages and Oral Manifestations

    • Syphilis is classified into early (lasting <1 year), latent (early stage lasting ≤1 year, late stage lasting >1 year), and late (tertiary) stages.
    • The primary lesion of acquired syphilis is the painless chancre, which may occur genitally or extragenitally and heals spontaneously within 3 to 8 weeks.
    • Dark-field microscopic identification of T. pallidum in smears from the chancre is the most specific test for diagnosing primary syphilis.
    • Secondary syphilis signs and symptoms, which appear 6 to 8 weeks after the chancre, include constitutional symptoms and mucocutaneous manifestations.
    • Generalized mucocutaneous manifestations of secondary syphilis include pruritus, nail involvement, and various skin lesions.
    • Oral mucosa manifestations of secondary syphilis include macular syphilides, mucous patches, papular syphilides, and condylomata lata.
    • Macular syphilides are red oval spots, while mucous patches are painless papules with erosions or superficial ulcers.
    • Papular syphilides are rare in the oral mucosa and may form slightly raised, firm nodules with a tendency to ulcerate.
    • Condylomata lata, which rarely appear in the oral cavity, are elevated, vegetating, or papillomatous lesions, usually found at the corners of the mouth and palate.
    • Diagnostic tools for secondary syphilis include dark-field microscopic examination, immunofluorescence, and serologic tests (VDRL, RPR, FTA-ABS, TPI, TPHA).
    • The differential diagnosis of secondary syphilis includes candidiasis, lichen planus, leukoplakia, aphthous ulcers, herpetic stomatitis, erythema multiforme, and trauma.
    • Oral manifestations of specific infections related to late syphilis include interstitial glossitis.

    Fungal Infections: Mucormycosis, Aspergillosis, and Histoplasmosis

    • Mucormycosis primarily affects debilitated individuals, with poorly controlled diabetes as the most common predisposing condition.
    • The disease has five major clinical forms, with the rhino-orbitocerebral form being the most common, characterized by low-grade fever, headache, malaise, and progressive lethargy.
    • Diagnosis of mucormycosis involves histopathologic examination revealing broad ribbon-like Rhizopus hyphae within necrotic tissues, and treatment includes liposomal amphotericin B and surgical debridement.
    • Aspergillosis is caused by Aspergillus, with the most common form being invasive pulmonary aspergillosis, characterized by fever, dyspnea, dry cough, and irregular oral ulcerations.
    • The disease is transmitted through inhalation of spores and affects individuals with primary and secondary immunodeficiencies, organ transplantation, and high-dose steroids.
    • Histopathologic examination of aspergillosis lesions demonstrates septate hyphae with 45-degree branching, and treatment involves voriconazole and posaconazole as the drugs of choice.
    • Histoplasmosis is caused by Histoplasma capsulatum and is endemic in warm and humid climates, with oral lesions occurring in approximately 35 to 45% of cases.
    • The disease is transmitted through inhalation of fungus spores and is endemic in specific areas like the United States, Africa, and Asia.
    • Oral lesions of histoplasmosis are characterized by irregular and indurated painful ulceration with a verrucous surface.
    • Differential diagnosis for mucormycosis includes nasal NK-T non-Hodgkin’s lymphoma, Wegener’s granulomatosis, and other systemic mycoses that affect the mouth.
    • Differential diagnosis for aspergillosis includes mucormycosis, nasal NK-T non-Hodgkin’s lymphoma, Wegener’s granulomatosis, and other systemic mycoses that affect the mouth.
    • Differential diagnosis for histoplasmosis includes malignancies, tuberculosis, and other systemic mycoses that affect the mouth.

    Viral Infections in Oral Pathology

    • Herpes zoster, secondary herpetic stomatitis, varicella, erythema multiforme, and herpangina are differential diagnoses for viral infections in oral pathology.
    • Cytologic examination confirms virally modified epithelial cells with acantholysis and formation of Tzanck cells in herpes zoster.
    • Antiviral therapy within 3 to 4 days from symptom onset is effective for herpes zoster, and prednisolone may alleviate acute symptoms and reduce the risk for postherpetic neuralgia.
    • Papilloma, a benign tumor of the surface epithelium, is often caused by human papillomavirus (HPV) types 6 and 11 and presents with multiple small projections.
    • Papilloma affects both sexes equally, usually between the ages of 30 and 50, and is commonly found on the tongue and soft palate.
    • Verruciform xanthoma hyperplasia of epithelial layers characterizes papilloma on histologic examination.
    • Focal epithelial hyperplasia (Morbus Heck) is caused by HPV types 13 and 32 and is commonly observed in American Indians, Eskimos, and South Africans.
    • Focal epithelial hyperplasia presents as multiple, slightly elevated, painless nodules and can also appear in adults.
    • Lesions of focal epithelial hyperplasia may spontaneously reverse after a few months to 2 years, and conservative surgical excision or laser therapy can be suggested for esthetic concerns.
    • Condyloma acuminatum, caused by HPV types 6 or 11, is a common, sexually transmitted disease presenting as painless, exophytic tumors with a "cauliflower-like" surface.
    • Condyloma acuminatum is characterized by parakeratosis, acanthosis, and elongation of rete ridges on histologic examination, with the preferred treatment being conservative surgical excision or electrosurgery.
    • Verruca vulgaris, associated with HPV types 1, 2, and 4, is transmitted intraorally through self-inoculation and is rarely observed in the mouth.
