Addendum

Ulcers of the stomach which do not belong to the category of simple ulcer are for the most part of pathological rather than of clinical interest.

Although miliary tubercles in the walls of the stomach are more frequent than is generally supposed, genuine tuberculous ulcers of the stomach are not common. The most important criterion of these ulcers is the presence of tuberculous lymphatic glands in the neighborhood, and of miliary tubercles upon the peritoneum corresponding to the ulcer. Sometimes miliary tubercles can be discovered in the floor and sides of the ulcer. Tuberculous gastric ulcers, when they occur, are usually associated with tuberculous ulceration of the intestine. In an undoubted case of tuberculous ulcer of the stomach reported by Litten, however, this was the only ulcer to be found in the digestive tract. Tuberculous gastric ulcers generally produce no symptoms, but they have been known to cause perforation of the stomach and hæmatemesis. Many cases which have been recorded as tuberculous ulcers of the stomach were in reality simple ulcers. Cheesy tubercles as large as a pea, both ulcerated and non-ulcerated, have been found in the stomach, but they are very rare.

Litten, Virchow's Archiv, Bd. 67, p. 615.

Typhoid ulcers may also occur in the stomach, but they are infrequent. Both perforation of the stomach and gastrorrhagia have been caused by typhoid ulcers, which, as a rule, however, produce no symptoms distinctly referable to the ulcer.

Syphilitic ulcers and syphilitic cicatrices of the stomach have been described, without sufficient proof as to their being syphilitic in origin.

Necrotic ulcers, probably mycotic in origin, may be found in the stomach in cases of splenic fever, erysipelas, pyæmia, etc.

Ulceration occurring in toxic, in diphtheritic, and in phlegmonous gastritis need not be discussed here.

Follicular and catarrhal ulcers of the stomach have been described, but without sufficient ground for separating them from hemorrhagic erosion on the one hand and simple ulcer on the other.

Hemorrhagic erosions of the stomach, to which formerly so much importance was attached, are now believed to be without clinical significance. They are found very frequently, and often very abundantly, after death from a great variety of causes.
