Objective Due to their rarity, the endoscopic features and clinical backgrounds of @entity14 lesions have not yet been fully investigated. The aim of this study was to reveal the characteristics of this disease entity. Methods A database search performed at the Department of Pathology of our institute identified 12 @entity706 @entity1 with involvement in the cecum, colon, and/or rectum. Data regarding the endoscopic, radiological, biological, and pathological examinations performed were retrospectively reviewed from their clinical records. Results The mean age of the @entity1 (5 @entity1 , 7 @entity1 ) was 58.7 years. Five @entity1 were classified as being Lugano system stage I, while the other seven @entity1 were stage IV. In all of the @entity1 , @entity14 presented with papular (n=4), polypoid (n=4), and flat @entity75 (n=4). No @entity2681 or @entity1066 were seen in any of the lesions. The initial pathological diagnoses included @entity1074 of @entity1074 (n=2) and @entity1960 / @entity4272 with infiltration of inflammatory cells (n=3), in addition to the correct diagnosis of @entity706 (n=7). Conclusion Colorectal involvement of @entity706 shows no @entity2681 or @entity1066 . These lesions could be macroscopically observed as papular, polypoid and flat @entity75 . Making a correct diagnosis of this disease based on the findings of biopsied samples is sometimes challenging. In such cases, multiple biopsies and/or endoscopic mucosal resection is required, in addition to appropriate consultation with pathologists.
