ARTICLE HIGHLIGHTS
Case characteristics
A 78-year-old male patient was admitted because of a 2-mo history of constipation and luminal narrowing of the rectum on sigmoidoscopy.
Clinical diagnosis
A submucosal spreading tumor of the rectum, such as lymphoma, was suspected.
Differential diagnosis
Chronic radiation colitis, inflammatory bowel disease.
Laboratory diagnosis
Elevated serum prostate specific antigen, suggesting prostate cancer.
Imaging diagnosis
Findings from pelvic magnetic resonance imaging led to a diagnosis of secondary linitis plastica of the rectum due to prostate cancer.
Pathological diagnosis
Metastatic rectal linitis plastica (RLP) due to prostate cancer.
Treatment
Loop sigmoid colostomy for immediate symptom relief and hormone therapy for prostate cancer.
Related reports
Metastatic RLP due to prostate is extremely rare, and this is the first case report to describe both computed tomography and magnetic resonance imaging findings.
Term explanation
There are no uncommon terms used in this manuscript.
Experiences and lessons
Although rare, careful evaluation with a high suspicion for other sites of malignancy, including the prostate, is needed when RLP is suspected on imaging studies.
