[Microscopic colitis. A possible diagnosis in secretory diarrhea]

Area of Science:

• Gastroenterology
• Pathology

Background:

• Microscopic colitis is a condition causing chronic watery diarrhea.
• It is diagnosed via colonoscopy and biopsy, revealing characteristic microscopic changes.

Observation:

• This study presents four cases: two of collagenous colitis and two of lymphocytic colitis.
• Patients presented with chronic watery diarrhea, a common clinical manifestation.

Findings:

• Microscopic colitis is characterized by chronic watery diarrhea, with or without abdominal pain.
• Diagnosis relies on microscopic examination of colon biopsies, as macroscopic appearance can be normal.
• Two distinct subtypes exist: collagenous colitis and lymphocytic colitis.

Implications:

• Understanding the distinct subtypes of microscopic colitis is crucial for accurate diagnosis and management.
• Further research into the pathogenesis and treatment of microscopic colitis is warranted.
