Pulmonary blastoma is a very rare malignant tumor of the lungs. A biphasic pulmonary blastoma was histologically diagnosed by a characteristic finding as it was mainly constituted of immature tumor tissue that had both epithelial and mesenchymal components. We present a case of a 68-year-old man with biphasic pulmonary blastoma. The patient underwent cranial metastatectomy and left lung upper l...

The following case reports seemed to me to be worth recording; the phenomena with which they deal, though well recognized in medical literature, are not so commonly encountered in general practice; in one, especially (Case 3), the difficulty in diagnosis in the earlier stages of the illness was not inconsiderable and gave rise to much interesting discussion. The association between bronchiectas...

Echinococcus multilocularis (EM) is caused by the larval stage of the tapeworm. The main endemic regions for human alveolar echinococcosis are Central Europe, Russia, Turkey, Japan, China, Eastern France, North America. EM is an endemic disease in Turkey and especially common in the eastern Anatolia Region as seen in our case. The liver is the primary focus of the disease, cerebral localization...

Malignant mesothelioma is an uncommon, highly invasive tumor derived from the mesothelial cells of pleura or peritoneum characterized by poor outcome. Mesothelioma was thought to metastasize locally only via direct invasion and not have distant spread. Distant metastases were discovered mostly on post-mortem examination. The authors present a case of 62-year-old man with pleural mesothelioma an...

Introduction: Myocardial metastasis from lung cancer is rarely found in antemortem settings. Herein we present a case of myocardial metastasis from lung adenocarcinoma presenting as cerebral infarction. Case Report: A 78­year­old Japanese female (non­smoker) who had been diagnosed with poorly differentiated lung adenocarcinoma suddenly complained of weakness in the left hand on a regular follow...

CONTEXT: Malignant melanoma is the third most common cause of cerebral metastases after breast and lung cancer. Despite advances in therapeutic options, the prognosis for patients with cerebral metastases from melanoma remains poor, with a median survival time of six months after diagnosis. CASE REPORT: A 65-year-old woman was diagnosed with a malignant melanoma on the third toe of her left f...

Cardiac myxoma is the most common benign tumor of the heart. Complete surgical removal of the myxoma is usually curative. However, low incidence of recurrence and metastasis has been reported with the brain being the most common site of cardiac myxoma metastasis (1). We report a rare case of delayed multiple cerebral metastases from the completely resected cardiac myxoma without evidence of loc...

Papillary carcinoma of the thyroid is well known for metastasis to regional lymph nodes resulting in early detection and overall favorable prognosis. Solitary metastasis of papillary carcinoma of the thyroid in the cerebrum is extremely rare with only a few cases reported in the literature. Here, we report an unusual case of a 40-year-old female patient who presented with neurological symptoms ...

Two unusual cases of brain metastasis from hepatocellular carcinoma (HCC) are described. A 15-year old boy presented with intracerebral hemorrhage from brain metastasis from HCC, and died of rebleeding 1 month after surgery. Cerebral metastatic HCC in a child is quite rare, and has not previously been reported. A 65-year-old male with a 2-year history of treatment for HCC presented with a brain...

Dysembryoplastic neuroepithelial tumors (DNETs) arise mostly in the supratentorial cerebral cortex. A very rare case of intraventricular DNET with diffuse ependymal involvement, which causes spinal drop metastasis, is presented.
