Introduction

Hepatic adenomas were well described but rarely encountered prior to the past decade. Henson et al (10) documented only four hepat­ ic cell adenomas in a review of the Mayo Clinic experience from 1907 to 1954. At the Los Angeles County Hospital between 1918 and 1974 only two liver cell adenomas were di­ agnosed out of a total of 418 liver tumors discovered in 50,000 autopsies (7). Hepatic adenomas have been seen more fre­ quently in clinical medicine coincident with the recent increased use of sex steroids. Bernstein et al. (4) in 1971 first reported the development of hepatocellular carcinoma in a patient with Fanconi’s syndrome receiving oxymethalone. In 1972, Johnson et al. (12) reported an addition­ al 4 patients who had developed hepatocellular

carcinoma while on androgenic steroid therapy. More recently Baum et al. (3) have reported 7 cases of benign hepatic adenomas in women using oral contraceptives. Since these original observations, many individual case reports and several substantial series of hepatic adenomas and hepatocellular carcinoma in patients using either estrogenic or androgenic hormones have been published (1 ,2 , 14, 15). Thus, the statisti­ cal association between the use of hormones and the development of hepatic neoplasia, though still questioned by some (9, 13), ap­ pears convincing (8). In addition to adenomas in individuals re­ ceiving sex steroids for medicinal reasons, spon­ taneous hepatic adenomas have been noted to occur in women during pregnancy, particularly in the last trimester (11) or in the early postpar­ tum period (5, 17). In addition to these preg­

Abstract. The development of a hepatic adenoma is described in a young female of reproductive age who had documented portasystemic shunting and hyperestrogenemia. The intrinsic hyperestro­ genemia and the increased hepatic arterial blood flow, both of which occurred as a result of the portasystemic shunting secondary to portal venous obstruction, may have been important factors in the development of her hepatic tumor. We would postulate that prolonged endogenous hyperestrogenemia, like exogenous sex steroids, may predispose to hepatic adenoma formation.

nancy-related hepatic adenomas, there is a re­ port of a hepatic adenoma developing in the presence of a functioning ovarian tumor (16). Thus, the presence of increased levels of sex steroids would seem to be associated with the development of adenoma formation in tire liver. Here we report tire spontaneous develop­ ment of a hepatic adenoma in a young female with prehepatic portal hypertension and docu­ mented endogenous hyperestrogenemia. We postulate that either the endogenous hyper­ estrogenemia or the increased hepatic arterial blood flow secondary to portasystemic shunt­ ing (or both acting together) may have been

risk factors in the development of hepatic neoplasia in this woman.

A 21-year-old Caucasian female, bom in 1954, was first hospitalized at age 5 with acute upper gastrointes­ tinal bleeding from esophageal varices. Splenoportog­ raphy demonstrated ‘cavernous transformation’ of the portal vein. A splenectomy was performed in an attempt to control bleeding. A liver biopsy obtained at that operation was reported as normal. At age 7 she underwent transthoracic ligation of esophageal varices for recurrent bleeding. At age 14 another major gastrointestinal hemorrhage occurred and arteriography again demonstrated esophageal vari-

Fig. 2. Celiac arteriogram obtained on Decem­ ber 27, 1971 for recurrent gastrointestinal bleeding indicated a hypervascular mass in the left hepatic lobe. Two dilated left hepatic artery branches encompass the mass (arrows) which measures 11 X 13 cm. The

mass contained multiple, fine, tortuous vessels, with normal attenuation, and no tumor stain or A/V shunt­ ing. The artériographie findings suggested a benign hepatic adenoma.

ces with a normal hepatic arterial pattern (fig. 1). In an effort to control the bleeding, transabdominal suturing of gastric and esophageal varices was per­ formed. 7 months later a 'Tanner- procedure (gastric interruption) was performed for recurrent hemor­ rhage. Despite these operative procedures another hemorrhage occurred 5 months later but was con­ trolled with peripheral Pitressin infusion. She did well thereafter, except for symptomatic esophageal reflux and the development of an esophageal stricture. At age 16 she underwent esophagogastrectomy and colon interposition, vagotomy and pyloroplasty for esopha­ geal stricture at Presbyterian-University Hospital of Pittsburgh. Biochemical liver function studies at that time are shown in table 1. Further gastrointestinal hemorrhage prompted performance of a mesocaval shunt at age 17. A preoperative angiogram demon­

strated enlargement of the left lobe of the liver, suggestive of an adenoma (fig. 2). In addition, the abnormal segment of portal vein had changed from multiple vessels to a single narrow irregular branch. The esophageal varices were noted again. A second liver biopsy obtained at that operation showed mild chronic persistent hepatitis. Despite the mesocaval shunt, gastrointestinal bleed­ ing recurred 1 year later. Liver function studies were only mildly abnormal (table 1). 4 months later the liver function studies had returned to normal except for a persistently elevated alkaline phospha­ tase. At age 21 she was re-admitted with abdominal pain and hematemesis. On admission she reported that her last menstrual period had been 4 months earlier. Moreover, she described her menstrual periods as

always having been irregular, occurring at 4- to 6month intervals. She was febrile with a temperature of 39.4 °C. Scleral icterus was noted. Multiple spider angiomata were present over the trunk. Serial blood cultures grew Streptococcus viridans. The white blood cell count was 27,600 mm3, hemoglobin 13.0g%and hematocrit 39.8%. Liver function studies were markedly abnormal (table I). She was treated with intravenous penicillin. An upper gastrointestinal series suggested hepatic en­ largement, but no varices were seen. A sonogram outlined an 8 X 10 cm cystic mass in the left upper quadrant that appeared completely within the hepatic parenchyma. A celiac arteriogram showed a marked change in the appearance of the hepatic mass (fig. 3) as compared to the previous examination (fig. 2). The

artériographie findings were interpreted as consistent with hemorrhage and/or necrosis within the tumor mass. The patient underwent exploratory laparotomy. The left lobe of the liver was found to be largely replaced by a fluctuant mass from which a large amount of semi-solid material, which cultured Staphy­ lococcus aureus, was encountered on incision. The left hepatic artery was ligated and the bulk of the mass was excised. The right lobe of the liver was grossly normal. Microscopically, the tumor was composed of cords of uniform well-differentiated hepatocytes con­ taining glycogen, occasional fat vacuoles, and abun­ dant granular brown iron-negative pigment presumed to be lipochrome (fig. 4). Bile ducts were absent, lobular architecture was lost and there was no evi­ dence of cirrhosis or bile stasis. Ischemic changes were

Discussion

The patient denied ever using oral contra­ ceptives. Moreover, she had not used, for ex­ tended periods, any other drugs that might be implicated in the pathogenesis of liver cell adenoma. The radioimmunoassay methods uti­ lized to assay the steroids in this patient’s sera included chromatographic separation which virtually eliminates estrogens other than estra­ diol. In addition, the antisera used are known not to cross-react with the synthetic estrogens 1 Normal postpubertal premenopausal I'SH levels: 6.5-30 mlU/ml; normal postpubertal premenopausal LH levels: 10-25 mlU/ml; normal estradiol levels: follicular 50- 125 pg/ml, luteal 125-200 pg/ml; nor­ mal progesterone levels: follicular
