“…Similar misinterpretations have also been reported (Table 2) (2,23,24). We recently analyzed the diagnostic accuracy of endoscopic biopsies for the diagnosis of gastrointestinal follicular lymphoma lesions, and we found 9/48 patients (18.8%) to not be appropriately diagnosed as having follicular lymphoma at the initial biopsy (10).…”

Objective Due to their rarity, the endoscopic features and clinical backgrounds of colorectal follicular lymphoma 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 follicular lymphoma patients 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 patients (5 men, 7 women) was 58.7 years. Five patients were classified as being Lugano system stage I, while the other seven patients were stage IV. In all of the patients, colorectal follicular lymphoma presented with papular (n=4), polypoid (n=4), and flat elevated lesions (n=4). No erosions or ulcers were seen in any of the lesions. The initial pathological diagnoses included extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (n=2) and colitis/proctitis with infiltration of inflammatory cells (n=3), in addition to the correct diagnosis of follicular lymphoma (n=7). Conclusion Colorectal involvement of follicular lymphoma shows no erosions or ulcers. These lesions could be macroscopically observed as papular, polypoid and flat elevated lesions. 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.

“…The median age was 65.8 (range: 56-75) years old, and the male-to-female ratio was 4:4. According to the Lugano classification, the ratio of clinical stages I:II1 was 6: 2 and the endoscopic appearances of papular, polypoid and flat elevated type were observed in 4, 2 and 2cases, respectively (7)(8)(9)(10)(11)(12)(13)(14), and all of which showed raised lesions (Table). Nakamura et al reported that the endoscopic features of intestinal lymphoma may be classified as polypoid, ulcerative, multiple lymphomatous polyposis (MLP), diffuse, and mixed type (15).…”

Primary Colorectal Follicular Lymphoma Observed by Magnifying Endoscopy, with a Five-year Follow-up

et al. 2020

Colorectal involvement is very rare in cases of follicular lymphoma. Colonoscopy of a 69-year-old man revealed an aggregation of multiple whitish nodules in the sigmoid colon. Magnifying endoscopy with narrowband imaging demonstrated a coiled and elongated microvascular pattern on the surface and crystal violet staining showed a type I pit pattern. A biopsy showed follicular lymphoma (Grade 1), and no other involvement of lymphoma was detected. Following a diagnosis of primary colorectal follicular lymphoma stage I (Lugano classification), the patient was monitored by watch-and-wait therapy. We documented the endoscopic images of colorectal follicular lymphoma in the present case.
