“…29 There are just as many reports in which HCC is described as growing extrahepatically, but the origin of HCC is not clearly identified. Such articles were excluded, because right-sided pedunculated HCC growing extrahepatically is often a fusion of metastatic adrenal HCC and the liver, 30 or HCC could have arisen in the liver and grown mainly extrahepatically. According to Yamashita et al, 9 there were 70 cases of ectopic liver reported in the literature up to 1985; they included 9 cases of HCC evolving in ectopic liver tissue.…”

Two patients with ectopic liver are described. In one patient, a small ectopic liver attached to the gastric serosa developed hepatocellular carcinoma (HCC). The preoperative diagnosis was an ␣-fetoprotein (AFP)-producing carcinoma and a malignant ulcer of the stomach. Total gastrectomy and esophago-jejunostomy were performed. The tumor that measured 4 ؋ 2 ؋ 2 cm contained an AFP-producing HCC and normal liver tissue. In another patient who had alcoholic cirrhosis, ectopic liver on the serosa of the gallbladder was found to have the same histological changes as the mother liver. A survey of the literature disclosed more than 20 cases in which HCC developed outside the liver; the liver did not have HCC. By contrast, there was only one report on HCC occurring in the liver in the presence of a noncancerous, relatively large accessory liver lobe. Because ectopic liver does not have a complete vascular and ductal system as a normal liver, it is perhaps functionally handicapped and more prone to hepatocarcinogenesis. (HEPATOLOGY 1999;29:57-61.)

“…The right adrenal is most often involved while bilateral involvement is uncommon. The route for metastasis is thought to be hematogenous, but there is also a possibility of direct invasion (10). Metastasis is often diagnosed incidentally by routine abdominal imaging.…”

Adrenal Hemorrhage as the First Presentation of Hepatocellular Carcinoma

et al. 2007

We report a 67-year-old man who presented with sudden onset of pain in the left flank in association with anemia and hypotension. Imaging studies revealed hepatocellular carcinoma (HCC) at the right lobe of the liver with bilateral adrenal metastases and recent hemorrhage in the left adrenal gland. His serology for hepatitis C was positive. Abdominal exploration with left adrenalectomy was performed. The postoperative course of the patient was uneventful and three cycles of transarterial chemoembolization (TACE) were administered. His general condition gradually deteriorated, and he died 6 months after surgery. Spontaneous massive AH due to metastatic HCC is unusual. Considering the high incidence of HCC in Asia, clinicians should be aware of this atypical and fatal presentation.

“…La plupart des carcinomes hépatocellu-laires décrits ont été découverts devant une masse abdominale [4,11,17,18] et simulent souvent une tumeur surrénalienne droite. [9,10]. L'examen physique retrouve souvent une masse abdominale de localisation variable.…”

Carcinome hépatocellulaire pédiculé. À propos d’un cas

Malgré la fréquence élevée du carcinome hépato-cellulaire (CHC) dans nos régions, le CHC pédiculé reste très rare. Nous présentons une observation d'un CHC pédi-culé découvert chez un patient de 79 ans. L'examen clinique montrait une masse de la fosse iliaque droite de 12 cm occupant le flanc droit et la région périombilicale. L'échographie et l'examen tomodensitométrique évoquaient une tumeur coecale. La laparatomie exploratrice révélait une tumeur pédiculée du lobe droit du foie dont la résection complète a été faite. Le CHC pédiculé est plus favorable à une résection curative que le CHC conventionnel, et son pronostic est meilleur après une résection complète et en l'absence d'invasion vasculaire. Mots clés Hépatocarcinome pédiculé · Résection complèteAbstract Despite the high incidence of hepatocarcinoma in our country, the pedunculated hepatocarcinoma is very rare. We present a case of pedunculated hepatocarcinoma of a 79-year-old patient's. The clinical exam had shown a mass in the right iliac fossae, 12 cm wide from the right to the periumbilical region. The echography and the scanner showed a tumor of the cecum. The laparotomy had shown a pedunculated tumor of the right liver, and a complete resection of this mass was done. The pedunculated hepatocarcinoma is more favorable by curative resection to the conventional hepatocarcinoma, and its prognosis is better after a complete resection without vascular invasion.
