INTRODUCTION Epithelioid hemangioma is a rare vascular tumor found in the penis. It is essential to avoid misdiagnosis with Peyronie's disease and penile cancer, as management differs significantly. CASE PRESENTATION We present a case of epithelioid hemangioma of the penis in a 50-year-old Caucasian man. We also review the literature to evaluate the incidence of benign vascular anomalies of t...

INTRODUCTION The pulmonary epithelioid hemangioendothelioma is a rare vascular intermediate malignancy tumour. CASE PRESENTATION A 45-year-old man, he shows an isolated chronic cough with a preserved general state of health. The thoracoabdominal Computed tomography showed three well limited opacities of the right lung, among them one shows some calcifications; which we entirely resected by en...

A 38-year-old male was admitted to our hospital due to upper abdominal pain. Computed tomography revealed a hepatic angiomyolipoma (AML; 10.5 × 9.5 × 7.0 cm in size), which had ruptured into the space between the liver and the diaphragm. Following transcatheter arterial embolization, surgical resection was performed. The tumor consisted of epithelioid cells (50-60%), mature fat (40-50%), and th...

OBJECTIVE Epithelioid glioblastoma is a rare morphologic subtype of glioblastoma that closely mimics metastatic carcinoma or metastatic melanoma histologically. All previous case reports of this unusual glioblastoma variant have been solitary lesions. We report here the first case to our knowledge of multifocal epithelioid glioblastoma mimicking cerebral metastasis. CLINICAL PRESENTATION A 67...

The sequential transformation of chicken monocytes into macrophages, epithelioid cells, and multinucleated giant cells in vitro was studied by electron microscopy after fixation and embedment in situ. The following changes occur. In the nucleus, margination of chromatin, evident in monocytes, decreases in later forms. Nucleoli become more complex and nuclear pores increase in number. In cytopla...

OBJECTIVE To determine common imaging findings of hepatic epithelioid hemangioendothelioma on magnetic resonance images. MATERIALS AND METHODS A search was made of three institutional databases between January 2000 and August 2012. Seven patients (mean age, 47 years; range, 21-66 years; 6 women) with pathology-confirmed diagnosis of hepatic epithelioid hemangioendothelioma who had undergone m...

INTRODUCTION Hepatic epithelioid hemangioendothelioma is a rare malignancy arising from the vascular endothelial cells within the liver. Historically, the disease is characterized as being poorly responsive to both chemotherapy and radiotherapy, with liver resection or transplantation the treatment of choice when feasible. For patients with advanced disease, reports of long-term therapeutic ben...
