Lymphocytic Colitis in Nigeria: A Case Series

The term “microscopic colitis” (MC) is used to describe a chronic inflammatory bowel disease that includes two main subtypes based on histopathologic features: collagenous and lymphocytic. Scientific literature is replete with documentation of the disease from various regions of the world. However, the condition is rarely described in black African patients. We herein present the details of the clinical aspects and endoscopic findings of 3 Nigerian patients with the lymphocytic variant of MC. A short literature review of the clinical, endoscopic, and pathologic features of this rare condition as well as other relevant aspects of MC is also presented.
