[Single nonspecific ulcer of the rectum]

Area of Science:

• Gastroenterology
• Colorectal Surgery

Background:

• Single, non-specific rectal ulcers represent a rare clinical presentation.
• Diagnosis typically requires a combination of endoscopic visualization and histological examination.

Observation:

• Four cases of single rectal ulcers were identified.
• A unique case involved a pregnant woman, leading to the decision to terminate the pregnancy.
• The rectal ulcer demonstrated potential for spontaneous healing and could coexist with duodenal ulcers.

Findings:

• Endoscopic and histological evaluations are crucial for diagnosing single rectal ulcers.
• Pregnancy presents a specific challenge, potentially necessitating intervention.
• Spontaneous remission and co-occurrence with other gastrointestinal ulcers are possible.

Implications:

• Patients diagnosed with single rectal ulcers require long-term follow-up.
• Annual monitoring for up to three years is recommended for these patients.
• This condition, though rare, warrants consideration in differential diagnoses for rectal bleeding and pain, especially in pregnant individuals.
