The occurrence of diffuse large B-cell lymphoma (DLBCL) of the appendix presenting as acute appendicitis is rare, constituting only a minuscule portion (0.015%) of gastrointestinal lymphoma cases. We present a case of a 55-year-old woman that was admitted to the emergency department with symptoms of acute appendicitis and underwent an interval laparoscopic appendectomy with a right hemicolectomy and lymph node resection. Pathological examination revealed the presence of DLBCL in the appendix. The patient is undergoing chemotherapy.

Primary colorectal diffuse large B-cell lymphoma (DLBCL) is very rare colon malignancy. Due to a possible delay in the diagnosis, it is important to know the main demographic and clinical characteristics of these patients. Retrospective analysis of 18 patients diagnosed with primary colorectal DLBCL during a 17-year period at the tertiary National Cancer Institute of Brazil (INCA) hospital. Demographic characteristics, tumor localization, HIV status, lactate dehydrogenase (LDH) levels, treatment modality and follow-up status were obtained from medical records. Survival was estimated from the date of diagnosis until death. There were 11 male and seven female patients in our cohort, the median age at diagnosis was 59.5 years and four patients were HIV positive. Tumor was mainly localized in the right proximal colon. Patients were treated with chemotherapy (CT) and/or surgical resection. Eleven patients died during a median follow-up of 59 months and the median survival time was 10 months for the whole group. Six or more cycles of CT (HR = 0.19; CI 95% 0.054–0.660, p = 0.009), low LDH levels (HR = 0.229; CI 95% 0.060–0.876, p = 0.031) and surgical resection (HR = 0.23; CI 95% 0.065–0.828, p = 0.030) were associated with reduced risk of death in univariate analysis. DLBCL affected more frequently middle-aged man and was primarily located in the right colon. These observations should be considered for differential diagnosis. Six cycles of CT, low LDH levels and surgical resection were associated with better survival. Our results are consistent with previous publications and address the importance of correct colorectal DLBCL diagnosis and treatment.
