_Symptoms._ Beside the general phenomena of catarrhal pharyngitis, this form of the malady is characterized by a greater swelling and tenderness of the throat, extending from ear to ear, and from the trachea forward in the intermaxillary space; by nodular and painful swellings of the pharyngeal lymph glands, by the greater difficulty of deglutition, the muscular tissue being involved; by wheezing breathing amounting at times to violent roaring and threatened asphyxia. Perspiration on the throat, the ear, the side of the head or neck, of the fore arm, or of the dorsal region is not uncommon, and has been attributed to the compression of the vagus, or of the superior cervical ganglion of the sympathetic by the swelling. Fever usually runs higher than in simple catarrhal pharyngitis, which may be partly accounted for by the implication of the deeper and important structures but also in no small degree by the entrance into the circulation of the ptomaines and toxins, which in the catarrhal affection escape largely from the inflamed surface. The resulting abscess is usually in or near a gland or group of lymph glands. The part passes through the usual succession of changes, of soft pitting swelling; firm, tense, painful condition in which the exuded lymph has coagulated; and softening and fluctuation which progresses from the centre toward the circumference. The abscess points variously according to its seat. If in the intermaxillary space it opens externally. If sub-parotidean or peripharyngeal it may burst inwardly into the pharynx or outwardly through the skin. If supra-pharyngeal (retro-pharyngeal), it may be so thickly encapsulated in unyielding walls that it may remain long indolent and inactive becoming a cold or chronic abscess. When an abscess opens into the pharynx, there is a sudden and copious flow of pus by the nose, and it may be by the mouth and a simultaneous subsidence of the inflammation. Among the _complications_ of the affection are asphyxia, œdema glottidis; abscess of the guttural pouch; rupture of an abscess into the larynx, and the descent of pus into the lungs; the entrance of saliva and alimentary matters into the lungs; gangrenous pneumonia; pharyngeal fistula; pressure on the vagus and paralysis of the pharynx or larynx; secondary abscesses; septicæmia. _Lesions._ Besides the general inflammatory lesions some rather remarkable ones have been observed. Fractured hyoid, dissection of the mucous from the muscular coat, by aliments, for nearly the whole length of the œsophagus (Brückmüller), purulent infiltration of the supra-pharyngeal muscles (Wakefield), ulceration of the pharyngeal or guttural sac mucosa, or even gangrene, purulent effusion in the tonsils, around the hypoglossal nerve, the lingual branch of the fifth, or the vagus, embolic inflammations, suppurations or gangrene of the bronchia, and implication of the lung tissue and pleura. Catarrhal enteritis and fatty liver and kidney are common.
