Although infiltration of the gallbladder by lymphoma is rare, it has to be considered in the differential diagnosis of patients presenting with cholecystitis-like symptoms. The most common lymphomas masquerading as acute cholecystitis are mucosa-associated lymphoid tissue lymphoma and large B-cell lymphoma. We describe a 75-year-old patient who presented with an acute cholecystitis-like picture, featuring chronic lymphocytic leukemia (CLL) with gallbladder wall involvement as the initial disease presentation. The cholecystectomy specimen showed perineural invasion present within the gallbladder wall, which likely accounted for the patient's right upper quadrant abdominal tenderness. In this way, we would like to alert clinicians and pathologists alike to CLL as yet another cause of a cholecystitis-like symptomatology.

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.

IgG4-related sclerosing disease is an established disease entity with characteristic clinicopathological features. Recently, the association between IgG4-related sclerosing disease and the risk of malignancies has been suggested. IgG4-related autoimmune pancreatitis with pancreatic cancer has been reported. Further, a few cases of extraocular malignant lymphoma in patients with IgG4-related sclerosing disease have also been documented. Herein, we describe the first documented case of anaplastic large cell lymphoma (ALCL) following IgG4-related autoimmune pancreatitis and cholecystitis and diffuse large B-cell lymphoma (DLBCL). A 61-year-old Japanese male, with a past history of DLBCL, was detected with swelling of the pancreas and tumorous lesions in the gallbladder. Histopathological study of the resected gallbladder specimen revealed diffuse lymphoplasmacytic infiltration with fibrosclerosis in the entire gallbladder wall. Eosinophilic infiltration and obliterative phlebitis were also noted. Immunohistochemically, many IgG4-positive plasma cells had infiltrated into the lesion, and the ratio of IgG4/IgG-positive plasma cells was 71.6%. Accordingly, a diagnosis of IgG4-related cholecystitis was made. Seven months later, he presented with a painful tumor in his left parotid gland. Histopathological study demonstrated diffuse or cohesive sheet-like proliferation of large-sized lymphoid cells with rich slightly eosinophilic cytoplasm and irregular-shaped large nuclei. These lymphoid cells were positive for CD30, CD4, and cytotoxic markers, but negative for CD3 and ALK. Therefore, a diagnosis of ALK-negative ALCL was made. It has been suggested that the incidence of malignant lymphoma may be high in patients with IgG4-related sclerosing disease, therefore, intense medical follow-up is important in patients with this disorder.

A 75-year-old woman is hospitalised for sepsis. The diagnosis of cholecystitis is made and an antibiotic therapy is debuted. The clinical worsening leads to realise an urgent cholecystectomy. A sepsis like shock persisted. The antibiotherapy was changed and a second abdominal look made. A severe lactic acidosis persisted since the cholecystectomy despite a continuous hemofiltration. The diagnosis of type B lactic acidosis secondary to malignancy was suspected. An osteomedullar biopsy revelled B-cell lymphoma EBV induced.

The involvement of the gallbladder in systemic lymphoma is extremely rare. We report a challenging case of systemic diffuse large B-cell lymphoma (DLBCL) that initially presented with septic shock from acalculous cholecystitis. After extensive investigation, DLBCL was found to be the underlying cause of gallbladder disease.
