Uptake of Tc-99m DISIDA in a bone metastasis from a hepatoma located at the humeral head is reported. Previous literature has only shown extrahepatic uptake of hepatobiliary agents in cases of lung metastases from hepatocellular carcinoma. The use of imaging with biliary tracers can increase the diagnostic specificity when bone metastases from hepatoma are suspected.

If conservative treatment of hypercalcemic crises is ineffective, low calcium bath or zero calcium bath hemodialysis represent good alternatives. We report 5 patients (from 54 to 82 years old) treated with calcium free acetate hemodialysis because of hypercalcemic crises due to breast cancer with bone metastases, thiazids' medication and immobilisation, liver cirrhosis, hepatocellular carcinoma and hyperparathyroidism. By 3 hours' therapy calcium concentration could be reduced from a mean value of 3.74 mmol/l (3.13-4.46) to 2.47 mmol/l (1.38-3.12). In 3 cases rapid clinical improvement was achieved and in 4 cases the subsequent conservative therapy was sufficient to maintain serum calcium levels within reference range. In accordance to other investigators we consider hemodialysis as an effective method of low risk in hypercalcemic crises. Calcium rebound may occur in patients with hyperparathyrodism.

Bone metastasis was observed in 16.1% or in 14 of 87 male autopsy cases of hepatocellular carcinoma. The primary tumor within the liver was located in the right lobe in all but one case. There were six patients who first presented with signs attributable to bone metastasis, and lung metastasis subsequently became evident in five of them. These 6 patients lived significantly longer as compared with 8 other patients with bone metastases and 73 patients without. The possible route by which hepatocellular carcinoma cells were carried to the bone is discussed.

While bone metastases producing photon deficient defects on bone scintigraphy have previously been reported, this finding has not been emphasized for hepatocellular carcinoma (HCC). Furthermore, "filling-in" of such photon deficient defects with 67Ga at skeletal sites of metastatic HCC has not been described. In this case report, the combination of a photon deficient defect on bone scintigraphy and avid accumulation of 67Ga in this same area was of value in confirming the diagnosis of metastatic HCC.

Forty-six patients who had been evaluated because of skeletal metastases of unknown origin, were reviewed. Twenty-six of the patients were referred to an orthopedic surgeon before confirmation of the metastases by biopsy; 20 others were referred to an oncology clinic after a diagnosis of bone metastases had been established. A simple diagnostic sequence consisting of a medical history, physical examination, routine laboratory studies, chest roentgenogram, technetium 99m phosphonate bone scintigram, and intravenous pyelogram identified the site of the primary tumor in 14 patients; 7 of the primaries were lung carcinomas, 4 were hypernephromas, 2 were breast carcinomas, and 1 was a prostate carcinoma. In two other patients, the histologic findings from the biopsy study were diagnostic; one had a thyroid carcinoma and one, a prostate carcinoma. Further extensive diagnostic workups revealed the site of origin in only four additional patients; two had hypernephromas which were discovered by computed axial tomography of the abdomen; one had an ovarian carcinoma and one had a hepatoma, both of which were found at laparotomy. On the basis of this study, a simple diagnostic strategy is recommended for patients with histopathologically confirmed skeletal metastases of unknown origin: medical history, physical examination, routine laboratory studies, chest radiograph, and technetium 99m phosphonate bone scintigram, followed by computed axial tomographic examination of the abdomen and pelvis. In female patients, it may be judicious to use mammography. If this regimen fails to reveal the primary site, it is unlikely that it will be identified with further extensive diagnostic procedures.

Although primary hepatocellular carcinoma is uncommon, metastasis to the upper extremity as a presenting symptom is even more rare. Recent case reports and autopsy surveys document that extrahepatic spread of this carcinoma occurs in 30% to 78% of patients, who usually are without regional symptoms involving bone. Although metastatic spread to the lungs and lymph nodes occurs more commonly, the incidence of bone metastases has increased according to previous reports and is now estimated from 2% to 13%. This case report concerns widely disseminated hepatocellular carcinoma presenting initially without any other systemic signs except for shoulder pain and induration. Due to the aggressive nature of this tumor, early detection is crucial. Early diagnosis may offer the only real hope for establishing effective treatment and improving the chances for long-term survival.

The data on 26 patients with solitary metastatic lesions arising in cortical bone were studied. Nineteen patients were over 50 years of age. In 19 patients, the cortical metastasis was the first indication of the presence of a primary malignant condition. In seven cases, cortical metastases developed in patients with a known primary tumor. The primary tumors involved were eight renal cell carcinomas, six bronchogenic carcinomas, two carcinomas of the gastrointestinal tract, one osteosarcoma, one neuroblastoma, one melanoma, one hepatoma, one carcinoma of the breast, and one thyroid carcinoma. In four cases, the primary tumor remained unknown. A metastatic origin should be considered in the differential diagnosis of an osteolytic lesion arising in the cortex of a long bone, especially in older patients and in patients with a known primary malignant condition. The cortical bone metastases encountered in this study did not originate solely from bronchogenic carcinoma, as has been reported by other authors. Cortical metastases are probably less rare than has been hitherto assumed.

A series of 30 patients is reported whose primary hepatic tumors had a distinctive histologic pattern that we have called "sclerosing hepatic carcinoma" (SHC). Sixty-nine percent of those tested had hypercalcemia and low levels of serum phosphate. As comparison, 38 control patients who had either classical peripheral cholangiocarcinoma or typical hepatocellular carcinoma were studied. In the control group, only two patients, who also had bone metastases, had hypercalcemia. Sclerosing hepatic carcinoma is characterized by intense fibrosis in which the tubular neoplastic structures are embedded. Although the tumor in each patient superficially resembled peripheral cholangiocarcinoma, on close inspection 63% were found to be of apparent hepatocyte origin, 20% were apparently ductal, and 13% were mixed or not distinguishable. One patient's tumor had the pattern of the rare cholangiolocellular carcinoma. The difficulty of histological diagnosis was well illustrated by the fact that none of premortem biopsies in 16 patients was correctly interpreted unequivocally as primary carcinoma of the liver. Many were misinterpreted as metastatic adenocarcinomas, most frequently of pancreatic origin. We believe that, by describing clinicopathological features, more attention will be drawn to this unique carcinoma of liver origin.

We report herein three cases of hepatocellular carcinoma revealed by bone metastases. The metastases were located in the skull, the iliac bone, and the femur. The metastases were treated by radiotherapy, and/or surgery. With regard to the liver malignancy itself, two patients were treated by tamoxifen and one by chemoembolizations. Two patients are alive 27 and 31 months after the first sign, and one died 31 months after the diagnosis. In conclusion, in patients with hepatocellular carcinoma revealed by bone metastases, long survival was obtainable in a few cases, and aggressive treatment could be of interest.

Conventional bone scintigraphy is often inconclusive in detecting bone metastases of hepatocellular carcinoma, suggesting the necessity of alternative scintigraphic agents. In this study, the diagnostic value of I-123 IMP scintigraphy was evaluated in 8 patients with 12 pelvic bone metastases from hepatocellular carcinoma, then compared with Ga-67 scintigraphy. Eleven of 12 lesions (91.7%) were detected by I-123 IMP scintigraphy; Ga-67 scintigraphy visualized 8 lesions (66.7%) in the same patient population. I-123 IMP scintigraphy is useful for detecting pelvic bone metastases of hepatocellular carcinoma with less physiologic accumulation in the intestine as compared with Ga-67 scintigraphy.
