Syphilitic Pharyngitis

DEFINITION.—A specific inflammation of the mucous membrane of the pharynx or of the mucous membrane and submucous tissues, the result of syphilis, and often associated with like disease in contiguous structures.

SYNONYMS.—Pharyngitis syphilitica, Pharyngitis specifica, Syphilitic sore throat, Syphilis of the pharynx.

ETIOLOGY.—Contamination by syphilitic virus is the sole cause, whether by direct inoculation or by systemic poisoning, hereditary or acquired. Direct inoculation proceeds from primary sores on the lips, tongue, cheek, and hard palate, themselves the result of actual contact with sores in other individuals. Initial sores have been seen upon the tonsils, palatine folds, pharynx, and even the epiglottis. Direct inoculation from secondary sores may be communicated by the tooth-brush, blow-pipe, pipe-stem, trumpet, mouth-piece of feeding-bottle, pap-boat, or similar article previously used by an infected individual. Uncleansed surgical instruments convey the disease in like manner.

PATHOLOGY AND MORBID ANATOMY.—Syphilitic pharyngitis—or, more strictly speaking, syphilitic sore throat—occurs in all varieties, primary, secondary, tertiary, and hereditary. Secondary manifestations are the most frequent, and primary sores the most infrequent. The primary sore is soft in some instances, and hard in others. Phagedænic ulceration may ensue. Secondary manifestations are usually bilateral, and often symmetric in configuration and distribution. They appear from a few weeks to a few months after infection, and are among the most frequent early manifestations of secondary syphilis. The inflammatory process begins in erythema, usually diffuse, often punctated, sometimes in patches. It extends from above downward more frequently than in the reverse direction, but may spread in any direction. The lesion commences upon the soft palate and tonsils more frequently than on the pharynx, but may commence in any portion of the oro-guttural cavity. Tumefaction ensues, with lividity of the surface. The epithelial cells become distended; the resulting opalescence, somewhat characteristic, eventually subsides into a central opacity, the true mucous patch or condyloma latum. Mucous patches vary in size from mere specks to large irregular surfaces, often the result of coalescences. They sometimes become red and granular and covered with purulent products. Microscopically (Cornil), they consist of thickened epithelium upon a base of proliferated lymphoid cells, which often infiltrate the deeper tissues extensively. They may disappear in the course of a few weeks by resolution and absorption. Sometimes suppuration occurs in small superficial abscesses which discharge upon the surface. Several abscesses discharging simultaneously in coalescence, an extensive ulcer may result, which, in repair, leaves a cicatricial trace of its site. Flat and circular bluish-white patches, due to thickening of epithelium, appear after the first year of constitutional syphilis, and may exist in association with the true mucous patch. They bleed readily on rough handling, but rarely undergo ulceration.

Tertiary manifestations may present within a few months after infection or not until many years. Gummatous infiltration of the connective tissue, diffused or circumscribed (syphiloma), follows diffuse or localized erythema, and then the gummata break down, discharge by ulceration, and leave deep-seated irregular ulcers with undermined edges and surrounded with inflammatory areolæ. These manifestations are much more frequent in the palate than in the pharynx, and the ulcerative process often destroys the uvula and large portions of the palate and palatine folds. When the pharynx and posterior surface of the palate are both ulcerated, cicatricial adhesions are sometimes inevitable, and thus serious stricture of the suprapalatine pharyngeal canal may ensue. The lesion may be quite limited in extent or may involve the entire pharynx. The ravages may become sufficiently extensive to involve the vertebra and the skull or to perforate the large blood-vessels. Cicatrization in the pharynx is vertical or stellate as the rule, and the peculiar pallid lustre of the cicatrices is quite characteristic of the syphilitic lesion. In many instances secondary and tertiary manifestations commingle. Ulceration is then more likely to extend superficially than in depth.

Hereditary manifestations pursue much the same course as tertiary manifestations. They usually occur before puberty, but are occasionally delayed until after maturity. Deferred tertiary and late hereditary manifestations sometimes present the characteristic ulceration of the commingled secondary and tertiary disease; and this form of ulceration is often incorrectly attributed to scrofulosis and to lupus.

SYMPTOMATOLOGY, COURSE, DURATION, COMPLICATIONS, AND SEQUELÆ.—The subjective symptoms of syphilitic pharyngitis are those of erythematous and ulcerative pharyngitis of like grade, except that there is very little pain. The course is chronic unless specific treatment be instituted, when prompt repair may be expected unless the general health has been much undermined. The duration is indefinite. The manifestations subside under treatment, and recur if it is not sufficiently prolonged. Complications occur with similar manifestations of syphilis in adjacent or contiguous or distant structures, as may be. The most frequent sequel in neglected cases is cicatricial stricture.

DIAGNOSIS.—Bilateral inflammation in symmetric distribution is very characteristic of syphilis. Irregular ulcers with undermined borders and surrounded by inflammatory areolæ are similarly characteristic. Acknowledged history of syphilis or the detection of syphilitic manifestations elsewhere serves to confirm the diagnosis. In cases of doubt a few days' treatment with specific remedies in large doses will almost invariably serve to clear up the diagnosis.

PROGNOSIS.—The prognosis as to life is good unless the ulcerations have become so extensive as to threaten perforation into blood-vessels or the patient has become greatly debilitated. The prognosis as to freedom from cicatricial adhesions and stricture is not good in the presence of lesions which have destroyed large territories of tissue, even under very careful management.

TREATMENT.—Specific medicines in positive doses constitute the most effectual treatment. Mercury is indicated in secondary lesions. Extensive ulcerative tertiary and hereditary lesions are peculiarly susceptible to large doses (30 to 90 or more grains daily) of potassium iodide, under the influence of which they often heal without any local applications whatever. As soon as a positive impression has been produced the dose may be diminished. The parts should be kept clean and comfortable by periodic douching with sprays of alkaline solutions, or, what is still more serviceable, with a ten-volume solution of hydrogen peroxide diluted with one or more parts of distilled water. The best local application to the edges of the pharyngeal syphilitic ulcers is the solid cupric sulphate. Chromic acid (1:8) is a serviceable local stimulant to indolent ulcers. Necrosed fragments of bone should be removed. Should any impediment to respiration take place during administration of the iodides, oedema of the larynx may be suspected, and should be looked for. Professional supervision is requisite for many months after the lesions have healed. Cicatricial sequelæ of stricture require surgical interference.
