Abstract:
Fungal elements are frequently noted overlying the base of chronic peptic ulcers of the stomach and it has been suggested that the fungi enhance the degree of necrosis and that these cases have protracted disease and deeper ulcers with more perforations. It has also been postulated that the number of fungal elements might be increased in the stomach of patients who are receiving potent medications such as H2-receptor antagonists to reduce gastric acidity, but there have not been adequate control studies, and the deleterious effects from the presence of the fungi in these cases have not been substantiated. We present a very rare case of invasive mucormycosis (phycomycosis) occurring in the base of a chronic gastric ulcer in a 55 years old diabetic male. This case was clinically and radiologically been mistaken for a gastric carcinoma. In addition, the ulcer was complicated by perforation and fungal septicemia with subsequent fatal outcome. The clinical, radiological and histopathological features are described together with a literature review of other reported fungal gastric ulcers.
Insights
Fungal elements in chronic gastric ulcers may worsen outcomes. This rare case of invasive mucormycosis in a diabetic male highlights potential misdiagnosis and fatal complications like perforation and septicemia.
Area of Science:
- Gastroenterology
- Mycology
- Pathology
Background:
- Fungal presence in chronic peptic ulcers is common but its impact remains unclear.
- Potent acid-reducing medications may increase gastric fungi, yet evidence is limited.
- Deleterious effects of fungi in gastric ulcers require further substantiation.
Observation:
- A rare case of invasive mucormycosis (phycomycosis) occurred at the base of a chronic gastric ulcer.
- The patient was a 55-year-old diabetic male with a history of gastric ulcer.
- The condition was misdiagnosed as gastric carcinoma clinically and radiologically.
Findings:
- The gastric ulcer was complicated by perforation and fungal septicemia.
- The patient experienced a fatal outcome.
- Histopathological examination confirmed invasive mucormycosis.
Implications:
- Invasive fungal infections, like mucormycosis, are a rare but serious complication of gastric ulcers.
- Early and accurate diagnosis is crucial to prevent life-threatening complications.
- This case underscores the importance of considering fungal etiology in complex gastric pathologies, especially in immunocompromised patients.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
