Cervical Spinal Cord Compression: A Rare Presentation of Hepatocellular Carcinoma

Rare Site Hepatocellular Carcinoma Metastasis

Introduction

Besides more common sites such as lung or peritoneum, hepatocellular carcinoma (HCC) can metastatize to rare sites. We report herein a new metastatic site of HCC: the nail-bed. We also review other recently reported rare site HCC metastases (RSHM).

Case Report

A 66-year-old woman with a 12-year history of resected-stage IA HCC who later presented lung, spleen and brain metastases treated with surgery, systemic therapies (sorafenib, sunitinib, capecitabine) and radiotherapy. The patient was referred to us because of a painful and rapidly evolving mass in the nail-bed of the left thumb. Biopsy confirmed nail-bed HCC metastasis, and the finger was amputated. The patient died few weeks later.

Conclusion

This case was an opportunity for us to review RSHM. This type of metastasis seems to be an early event, in the context of advanced stage HCC with elevated protein induced by vitamin K absence-II (PIVKA II). The Lee nomogram is useful in detecting patients at high risk of developing RSHM. We would suggest insisting on systemic treatment in these metastatic patients although overall survival after RSHM diagnosis is poor.

Hepatocellular carcinoma presenting as spinal cord compression in Native Americans with controlled hepatitis C: two case reports

Background

Hepatocellular carcinoma is a common malignancy in Asia. It is associated with chronic hepatitis B virus or hepatitis C virus infection and alcoholic hepatitis. Commonly, the tumor metastasizes to the lungs, regional lymph nodes, and bone. Recently, the incidence of metastatic spinal cord compression caused by primary hepatocellular carcinoma has been reported more frequently due to improved diagnosis and therapeutic modalities. The presentation of primary hepatocellular carcinoma with spinal cord compression is very rare. To the best of our knowledge, there are only 33 such cases published to date. The majority of cases involve patients of Asian origin and are associated with hepatitis B infection.

Case presentation

We report consecutive cases of two Native American (American Indian) patients (a 64-year-old man and a 70-year-old man) who presented with symptoms of spinal cord compression due to metastatic spread of hepatocellular carcinoma and were associated with hepatitis C infection. In one of these cases, the hepatitis C infection had been successfully controlled (hepatitis C titers were undetectable for 1 year before he presented with spinal cord compression). This occurrence in a Native American with a controlled hepatitis C infection has not been reported previously.

Conclusions

Primary care physicians, oncologists, and gastroenterologists should be cognizant of this unusual presentation of hepatocellular carcinoma in a Native American. Such knowledge may help improve early diagnosis and survival.
