Program of INTRODUCTION TO ORAL MEDICINE and PATHOLOGY 1. White lesions: • Reactive hyperkeratoses: frictional (linea alba, morsicatio mucosae oris, frictional hyperkeratosis, bARK); tobacco-related (chewing tobacco lesions, nicotinic stomatitis, reverse smoking, cigar lesions); physical stimuli (actinic cheilitis). • Idiopathic hyperkeratoses: leukoplakia, proliferative verrucous leukoplakia. • Genodermatoses: white sponge nevus. • Immune-mediated hyperkeratoses: Oral Lichen Planus and Oral Lichenoid Lesions, cGVHD, lupus erythematosus. • Infectious hyperkeratoses: hairy leukoplakia, chronic hyperplastic candidiasis. • Other white lesions: acute pseudomembranous candidiasis, oral submucous fibrosis, chemical burns, dentifrice-associated necrotizing stomatitis. 2. Oral Squamous Cell Carcinoma: epidemiology, risk factors, pathogenesis, clinical features, diagnosis, treatment, prevention of oral complications of oncological therapies. 3. Oral Potentially Malignant Disorders: leukoplakia, proliferative verrucous leukoplakia, erythroplakia, reverse smoking lesions, Oral Lichen Planus, Oral Lichenoid Lesions, lupus erythematosus, cGVHD, actinic cheilitis, oral submucous fibrosis, chronic hyperplastic candidiasis, verrucous exophytic hyperplasia, Fanconi anemia. 4. Pigmented lesions: • Endogenous: ethnic pigmentation, reactive melanoses (smoker’s, inflammatory, drug-induced), single and multiple melanotic macules, melanocytic nevi, melanoma. • Exogenous: pigmentation from metals or amalgam, tattoos, foreign bodies. 5. Oral infectious diseases: • Viral: HSV-1/2, VZV, EBV, CMV, HHV-8, Coxsackie, measles, oral manifestations of HPV. • Bacterial: streptococcal pharyngitis, scarlet fever, actinomycosis, tuberculosis, syphilis, gonorrhea, leprosy. • Fungal: candidiasis, deep and opportunistic mycoses. • Parasitic: leishmaniasis, toxoplasmosis. 6. Soft tissue Reactive lesions and tumors: traumatic pseudofibroma, epulis, peripheral giant cell granuloma, peripheral ossifying fibroma, mucocele and ranula, drug-induced gingival hyperplasia, lipoma, granular cell tumor, hemangiomas and vascular malformations, lymphangiomas, overview of malignant neoplasms, Kaposi’s sarcoma, oral metastases.
