PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: gastrointestinal mucormycosis is rare disease. Case
reports are of high value to alarm physician to consider it in differential
diagnosis of GIT bleeding.
I have the following comments for respected authors:
1. in line 72: Overall, the intestines (64.2%) (large intestine, 43.2%; small
intestine, 28.4%). I think he percentage needs revision as you mentioned that
intestine 64.2% (43.2+28.4=71.6%).
2. Are there risk factors for peptic ulcer in both patients (e.g. drugs or
medication, alcoholism, unusual food habits). in case 2: are there any NSAIDs
used after leg sprain. 
3. nutritional status of patients are worth to be mentioned.
4. Do they have history of gastric upset or upper GI manifestation?
REQUESTED REVISIONS: 
add gastrointestinal symptoms, nutritional status, drug history, dietary habits
