2. =Tongue.= Mucosa normally is moist and grayish-red. Note discolorations, coatings, crusts, scabs, exudates, various forms of stomatitis, “geographical tongue,” glossitis, abscess, fissures, ulcers (syphilis, carcinoma, decubital), chancre, wounds, action of corrosives, scars (epilepsy, syphilis), tuberculosis, neoplasms (carcinoma, lymphangioma, hæmangioma, papilloma, leukæmic lymphocytoma, adenoma, thyroid adenoma [struma baseos linguæ], and rarely sarcoma, congenital fibroma, lipoma, myxoma, chondroma, osteoma and dermoid cysts), thrush, actinomycosis, leprosy, trichinæ, cysts (lymphangiectatic), hyperkeratosis, leukoplakia, “black hairy tongue,” macroglossia, partial or total hypertrophy. All forms of syphilitic lesions may be found upon the tongue (chancre, condyloma, plaques, papules, fissures, rhagades, ulcers, gumma, etc.) “Smooth atrophy” of the base of the tongue is regarded by various authors as pathognomonic of tertiary or congenital syphilis. Cysticercus and echinococcus are very rare. 3. =Pharynx.= Normal mucosa is smooth and gray-red. Note contents, color and character of mucosa, atrophy, congestion, œdema, exudations (mucous, purulent, croupous, diphtheritic, thrush), ulcers, scars, hyperplasia of lymph-follicles, adenoids, various forms of acute and chronic pharyngitis, retropharyngeal abscess, syphilis, tuberculosis, neoplasms (nasal polypi, lymphosarcoma, leukæmic lymphocytoma, aleukæmic lymphocytoma, carcinoma, retropharyngeal dermoids, lipoma, cysts, fibroma, chondroma, etc.), glanders, leprosy, actinomycosis, rhinoscleroma, cysticercus and echinococcus. 4. =Tonsils.= Size (how far do they project?), smooth or showing depressions, color (normally uniformly gray-red), atrophy, hypertrophy, hyperkeratosis, various forms of inflammation (acute and chronic tonsillitis, diphtheria, angina superficialis, lacunaris, follicularis, pseudomembranosa, purulenta and phlegmonosa, tonsillar ulcers, cysts and abscess), syphilis, tuberculosis, actinomycosis, thrush, concretions, neoplasms (carcinoma, primary is rare, secondary from primary in tongue or larynx more common; lymphosarcoma or lymphocytoma, either aleukæmic or leukæmic, is the most common neoplasm of the tonsil, other forms of sarcoma and connective-tissue tumors are rare), cysticercus and echinococcus are rare. 5. =Nose.= If the brain is not removed and the nasal tract not examined by the method of Harke, as much of the nose as possible should be inspected, and the various conditions noted, as described in Chapter VI.
