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.
