Primary non-Hodgkin lymphoma (NHL) of the gallbladder (GB-NHL) is exceedingly rare. We present our experience on a 78-year-old male with chief complaints of fever, chills, and epigastric dull pain. Abdominal computed tomography (CT) scan showed a few stones and focally thickened gallbladder wall. He received cholecystectomy under the preoperative diagnosis of acute cholecystitis with septic shock, while pathologic examination revealed cholelithiasis and diffuse large B-cell lymphoma without acute inflammation. Staging procedures revealed a stage IE tumour and the patient received adjuvant radiotherapy. Relapse as a large retroperitoneal mass was noted 32 months later and he passed away three years after initial diagnosis. A literature review revealed 20 cases of GB-NHL. We find that, including our current case, the median age is 63 years and 8 of 19 (42%) tumours are associated with gallstones. The mean and median survival of 15 patients with complete follow-up information is 75 and 36 months, respectively. Mucosa-associated lymphoid tissue (MALT) lymphoma seems to carry a longer survival than non-MALT lymphomas.

Lymphomas of the gall bladder and extrahepatic bile ducts are exceedingly rare. We present the clinicopathological features of 19 cases from our files; 14 patients had primary lymphoma (13 involving gall bladder and 1 involving common hepatic duct), while 5 had systemic lymphoma on further work-up. Most patients presented with symptoms mimicking cholecystitis. The most common primary lymphoma types were diffuse large B-cell lymphoma, extranodal marginal zone lymphoma, B-lymphoblastic lymphoma, and follicular lymphoma. Two cases had features of lymphomatous polyposis, one a case of follicular lymphoma and the second a case of mantle cell lymphoma, with disease limited to the mantle zones, so-called in situ mantle cell lymphoma. Other rare lymphoma subtypes not described earlier in this site included the extracavitary variant of primary effusion lymphoma and plasmablastic lymphoma. Patients with diffuse large B-cell lymphoma and extranodal marginal zone lymphoma were older (mean age 75.8 y) than those with other subtypes (mean age 47 y) and more likely to have gallstones (60% vs. 12.5%). A comprehensive literature review revealed 36 primary gall bladder and 16 primary extrahepatic bile duct lymphomas. When compared with primary gall bladder lymphomas, those involving the extrahepatic bile ducts present at a younger age (47 y vs. 63 y) usually with obstructive jaundice, and are less often associated with gallstones (17% vs. 50%) or regional lymph node involvement (6% vs. 31%). In conclusion, primary lymphomas of the gall bladder and extrahepatic bile ducts show a broad spectrum of disease types, but in many respects mirror the spectrum of primary lymphomas of the gastrointestinal tract.

A 50-year-old man visited a physician due to continued right hypochondrium pain for a period of about two months. He was diagnosed with cholecystitis and was referred to our hospital. On arrival, he presented with mild tenderness in the right upper quadrant. Abdominal computed tomography (CT) showed small gallstones and a thickened gallbladder wall. At the same time, a low-density area expanding from the gallbladder bed was revealed. Magnetic resonance cholangiopancreatography (MRCP) showed a smooth stricture of the common hepatic duct. We suspected chronic cholecystitis and inflammatory change in the liver because of cholecystitis. However, malignant diseases could not be excluded, and conservative treatment with antibiotics was therefore performed. On post-hospitalization day 26, cholecystectomy was performed. Rapid diagnosis of a surgical wedged biopsy specimen of the liver showed infiltration of the hepatic sinusoids by atypical lymphocytes. Malignant lymphoma was highly suspected. After further examination, we obtained the diagnosis of primary hepatic CD5+diffuse large B-cell lymphoma. Cyclophosphamide+doxorubicin+vincristine+prednisolone(CHOP) with rituximab therapy was performed. Complete remission was achieved after 8 courses of therapy. However, tumor recurrence in the floor of the mouth occurred one year after the operation. Salvage chemotherapy is now being performed.

While alcohol and gallstones have been considered the most common causes of pancreatitis, we investigate two uncommon etiologies such as drug-induced and viral-induced. Pancreatitis, an inflammatory process, can lead to many complicated outcomes such as acute respiratory failure, sepsis, and death. Examining drug-induced pancreatitis poses a large challenge for physicians as majority of the data is extrapolated from case reports. This is made even more difficult for patients who are on large chemotherapeutic regimens which include multitude of drugs and various side effects. Besides patient medication regimens, other etiologies of pancreatitis must be ruled out such as viruses. We examine a case of a 48-year-old female undergoing treatment for diffuse large B-cell lymphoma with various chemotherapeutic agents and positive cultures for varicella zoster virus (VZV) presenting with diffuse epigastric abdominal pain.
