Peritoneal lymphoma with ascites mimicking portal hypertensive ascites: A case report

Rapid Onset Chylous Ascites Presenting as the Initial Manifestation of Follicular Lymphoma: A Case Report

Follicular lymphoma is the most common indolent Non-Hodgkin Lymphoma (NHL) with overall survival measured in years for the majority of patients (NHL carries a somewhat positive prognosis). Baseline clinical genetic characteristics appear to be the best predictors of the clinical course. A few cases appear to be familial; however, no consistent environmental or infectious causation has been identified. Our presenting patient has a case of follicular lymphoma that was initially diagnosed in the setting of rapid onset chylous ascites, a highly atypical and rare presentation. Follicular lymphoma typically presents with painless lymphadenopathy in lymph nodes along the torso. The lymphoma cells divide within the nodes and can be palpated as bumps within the axilla or on the neck above the clavicle. Various prognostic indicators and tumor grading can give providers a sense of survival statistics. Once diagnosed, chemotherapy tends to form the backbone of most treatment regimens with various roles for immunotherapy and radiation.

Diffuse large B-cell lymphoma initially presenting with peritoneal dissemination

A 62-year-old woman with a severely distended abdomen and no palpable superficial lymph nodes visited the hospital. Computed tomography with contrast enhancement revealed multiple fused and homogeneously contrasting masses filling the abdominal cavity. She was diagnosed with diffuse large B-cell lymphoma by ultrasound-guided needle biopsy performed on admission.

Non-Hodgkin's Lymphoma Presenting as Isolated Peritoneal Lymphomatosis: A Case Report and Literature Review

Peritoneal lymphomatosis is extremely rare and associated with poor prognosis. Most practitioners only pay more attention to peritoneal carcinomatosis. However, peritoneal lymphomatosis can be neglected and misdiagnosed. We report a teenager with 10 days of abdominal distension and pain accompanied by computed tomography scan suggesting diffuse thickening of the peritoneum and omentum and abdominopelvic effusion. Tuberculous peritonitis and peritoneal carcinomatosis were initially suspected. However, it was finally confirmed as non-Hodgkin’s B-cell lymphoma by omentum biopsies. He achieved complete remission after chemotherapy and autologous stem cell transplantation. But unfortunately, he suffered a relapse and died 10 months after diagnosis. Following a review of the literature, it can be concluded that the discovery of lymphomatosis in peritoneum is a rare finding. Lymphoma should be considered in the differential diagnosis of unexplained peritoneal thickening on computed tomography, and this case emphasizes the importance of early pathological diagnosis to make sure that the right treatment can be started opportunely.
