“…RLH is a benign condition that may occur, besides in liver, in the gastrointestinal tract [26], orbit [27], lung [28], skin [29], and thyroid [30]. Hepatic RLH was first reported by Snover et al in 1981[8], and only 34 cases have been reported in the English literature until now [1–25, 31, 32].…”

Background. Reactive lymphoid hyperplasia (RLH) of the liver is a benign focal liver mass that may mimic a malignant liver tumor. Although rarely encountered in clinical practice, it often poses diagnostic and management dilemmas. Methods. Cases diagnosed as hepatic RLH between January 1996 and June 2011 were investigated in a retrospective study. Clinicopathological features as well as follow-up information of the cases were studied. Results. A total of seven cases of hepatic RLH were investigated, with a median age of 46 years (range: 33–76 years). Hepatic RLH was accompanied by concomitant diseases in some patients. The average size of hepatic lesions of our cases was 45 mm (range: 15–105 mm). All of the cases were not accurately diagnosed until confirmed by pathological findings, and surgical resections were performed for all. Postoperative course was uneventful for all of the patients during followup. Conclusions. RLH of the liver is a rare benign disease with a female predilection of unknown etiology. It is very difficult to correctly diagnose this disease without pathological results. Subtle differences on radiological findings of it may be helpful for differential diagnosis from other diseases. Curative resection of the lesion is suggested for the treatment of this disease.

“…Many cases of so-called pseudolymphoma of the stomach were reported until the concept of extranodal marginal zone B-cell lymphoma of mucosaassociated lymphoid tissue (MALT lymphoma) was advocated by Isaacson and Wright in 1983. However, most of the reported gastric "pseudolymphomas" are presently thought to be MALT lymphoma or other kinds of malignant lymphomas [3]. Anecdotal case reports concerning pseudolymphoma of the kidney, testis, prostate, thyroid, larynx, tongue, esophagus, gallbladder and spleen have been published.…”

“…Pseudolymphoma can occur in various organs such as the skin, orbit, lung, and gastrointestinal tract [ 2 , 3 , 4 , 5 ]; it rarely occurs in the liver. Pseudolymphoma of the liver was first reported by Snover et al [ 13 ] in 1981.…”

“…Pseudolymphoma is a benign nodular lesion that is histopathologically characterized by marked proliferation of nonneoplastic, polyclonal lymphocytes which form follicles with an active germinal center [ 1 ]. Pseudolymphoma can occur in various organs such as the skin [ 2 ], orbit [ 3 ], lung [ 4 ], and gastrointestinal tract [ 5 ], but it is rare in the liver. The preoperative diagnosis of hepatic pseudolymphoma is difficult because noninvasive radiological examinations such as ultrasonography (US), computed tomography (CT), and magnetic resonance imaging are usually equivocal.…”

A 69-year-old woman with chronic hepatitis B was admitted to our hospital with a hepatic tumor. The levels of 2 tumor markers, carcinoembryonic antigen and carbohydrate antigen 19-9, were slightly elevated; however, the α-fetoprotein and protein levels induced by vitamin K antagonist II were within the normal limits. Abdominal ultrasonography showed a well-defined peripheral hypoechoic mass that was isoechoic and homogeneous on the inside. Computed tomography showed a poorly enhanced tumor of 13 mm in diameter in the 5th segment of the liver. Fluorodeoxyglucose positron emission tomography showed a slight uptake (maximum standard uptake value 3.4) by the hepatic tumor. These findings suggested cholangiocellular carcinoma, and we performed anterior segmentectomy of the liver. A histopathological examination showed a hepatic pseudolymphoma. The patient’s postoperative course was uneventful, and she remains alive without recurrence 5 months after undergoing surgery. In most cases, hepatic pseudolymphoma is preoperatively diagnosed as a malignant tumor and a definite diagnosis is made after resection. It is therefore necessary to consider hepatic pseudolymphoma as a differential diagnosis in patients with hepatic tumors.
