Primary hepatic actinomycosis is rare, and there have been few reports concerning its nuclear imaging findings. Two cases of actinomycosis, in which hypervascular hepatic masses were observed in the arterial phase of radionuclide angiography are reported. To the authors' knowledge, this finding has not been reported in the literature. In one of the two cases, intense Ga-67 uptake also was noted. Although the preoperative diagnosis based on the findings of nuclear imaging (liver scan, liver flow study, Ga-67 scan), ultrasound, CT, and angiography was hepatoma, hepatic masses in our cases proved to be hepatic actinomycosis. Because hepatic actinomycosis is rare, this disease is neglected often in the differential diagnosis of hepatic mass lesions. It should be included in the gamut of hypervascular hepatic mass lesions.

All liver histology records from Tonga during 1970-79 were reviewed, including 42 biopsy and one necropsy specimens. Primary hepatocellular carcinoma was the histological diagnosis in 13 (30 percent). The age standardised incidence rate for confirmed cases are: males 2.9 and females 1.5 per 100 000. These are unremarkable compared to some reported rates, but many of these areas have included a high percentage of unconfirmed cases. Other diagnosis included cirrhosis (14), cholangiocarcinoma (2), metastatic carcinoma (2), cholangitis (2), hepatic fibrosis (2), and actinomycosis (1). The difficulties of diagnosis and areas for further studies are discussed.

A 64-year-old man with hepatic actinomycosis presented with several months of weight loss and poor appetite. However, no fever was noted before admission. Findings on abdominal sonography and computed tomography scan were suggestive of hepatocellular carcinoma. A sono-guided percutaneous liver biopsy specimen demonstrated only chronic fibrosing inflammation. Therefore, laparotomy was performed and the diagnosis of hepatic actinomycosis was established after surgical resection. The patient was then successfully treated. The fact that hepatic actinomycosis may be very similar to hepatocellular carcinoma should be highly suspected. The hospital course of this patient concerning this condition and a brief review of the literature are presented to illustrate the diagnostic difficulties which may be encountered in such cases.

A case of visceral botryomycosis of the liver in a 50-year-old man is reported. The clinical diagnosis was hepatocellular carcinoma. Pathological examination of the surgically resected specimen demonstrated microabscesses containing gram- positive microorganisms with surrounding fibrosis replacing liver parenchyma. An immune deficiency state was not demonstrated. Recognition of this condition is important because of its clinical confusion with malignancy and its histological similarity to actinomycosis, nocardia, and eumycotic infections.

Primary hepatic actinomycosis is relatively rare, but it should be remembered in the differential diagnosis of liver masses. A 66-year-old woman with right hypochondralgia was admitted and for detailed examination and treatment of a liver tumor. Abdominal ultrasonography revealed a hypoechoic lesion 55 mm in diameter in the anterior segment. Enhanced CT showed a deep-stained tumor in the early phase and a low density area in the late phase. The feeding arteries were the right hepatic artery and right inferior phrenic artery on abdominal angiography. The patient was given a diagnosis of hepatocellular carcinoma with invasion of the inferior lobe of the right lung. We performed a central bisegmentectomy of the liver and partial resection of the inferior lobe of the right lung. Microscopic findings of the resected specimen revealed sulfur granules and the tumor was diagnosed as primary hepatic actinomycosis.

We report a case of primary hepatic actinomycosis showing elevation of serum protein induced by vitamin K absence or antagonist II (PIVKA-II). A 68-year-old man visited an affiliated hospital with a complaint of high fever and body weight loss. Hematological examination revealed severe inflammatory reactions and liver dysfunction. Abdominal CT showed a heterogeneous low density area composed of cystic and solid part. We suspected the cystic part with band-like enhancement to be a hepatic abscess and performed percutaneous transhepatic abscess drainage. Although inflammatory reactions decreased after the drainage, the solid part did not shrink and blood chemistry revealed elevation of PIVKA-II. Since we could not rule out the possibility of hepatoma, right hepatectomy was performed. Histological examination revealed actinomycetes. Although primary hepatic actinomycosis is a rare disease, it must be kept in mind in the differential diagnosis of the liver tumor.

A 60-year-old man presented with odynophagia after bronchial artery infusion chemotherapy for pulmonary metastasis of hepatocellular carcinoma. Esophagogastroduodenoscopy (EGD) revealed an esophageal ulcer in the middle thoracic esophagus. An esophageal biopsy demonstrated no malignancy. However, the symptoms had not improved after a month. EGD was performed again and showed a white cord lump at the bottom of the same esophageal ulcer identified before, showing no improving tendency. A repeated biopsy of the lump revealed actinomycosis, and the symptoms were improved by the oral administration of ampicillin. We herein report a case in which esophageal actinomycosis with a unique morphology of refractory esophageal ulcer was rapidly improved by the administration of antibiotics.
