  • Abstract
  • Look Inside

We report 3 cases of calvarial tumor metastasized from the following malignancies: squamous cell car-cinoma of the lung, hepatocellular carcinoma, and clear cell carcinoma of the kidney. All three patients pre-sented with a painful mass as the initial symptom. Although each tumor was successfully extirpated, out-come was not satisfactory because of the malignant nature of the primary sources.

The main purpose of treatment of metastatic calvarial tumors was thought to be relief of pain andcosmetic reasons. Metastatic calvarial tumors may reach considerable size as reported here. We stressedthat meticulous care should he paid to repair of the dura and reconstruction of subcutaneous soft tissues,since scalp necrosis or cerebrospinal fluid retention may occur following preoperative embolization of feed-ing arteries and extensive removal of subcutaneous tissues invaded by tumor.
