Hepatoblastoma is the most common primary liver tumor of childhood and after neuroblastoma and nephroblastoma the third most common abdominal neoplasm in this age group. Hepatoblastoma is an embryonal tumor classified by histology as epithelial (including pure fetal subtype, mixed embryonal/fetal subtype, macrotrabecular subtype and small cell(More)
INTRODUCTION Although variations in the origin of the testicular artery are not uncommon, few reports about a high origin from the abdominal aorta exist in the literature. We discuss the case of a high origin of the testicular artery, its embryology, classification systems, and its clinical significance. CASE PRESENTATION We report a very rare case of(More)
INTRODUCTION Primary malignant hepatic mesotheliomas are extremely rare. We report the case of a patient with primary intrahepatic malignant mesothelioma who was treated in our department. PRESENTATION OF CASE A 66-year old male patient was admitted to our department for the evaluation of anemia. An abdominal computed tomography scan revealed a large(More)
INTRODUCTION The anatomical variations of bones in the hand are common. The existence of exostosis and shortening of metacarpal bones has been described in the literature as part of the hereditary multiple exostosis syndrome but no case has been reported with the co-existence of sesamoid ossicles in the same patient. CASE PRESENTATION We report a case(More)
BACKGROUND Congenital chylous ascites is a rare condition that constitutes a challenge for the physician. It is defined as the accumulation of chyle into the peritoneal cavity in infants younger than 3 months. This condition is often refractory to therapy and it is responsible for serious malnutrition and immunological deficiency because of the loss of(More)
A case of failure of palmaris longus muscle duplication was found in the left forearm of a male cadaver. Specifically, two distinct palmaris longus muscles had failed to separate, and were united from the medial epicondyle to the palmar aponeurosis. We studied the exact morphology of the abnormal muscle, which, to our knowledge, has not been reported(More)
INTRODUCTION The sensory innervation of the hand is usually unvarying and anomalies in this area are uncommon. CASE PRESENTATION We report the case of a rare ulnar nerve branch called a Kaplan anastomosis, which anastomosed the dorsal cutaneous branch with the ulnar nerve prior to its bifurcation into the superficial and deep ramus. CONCLUSION Many(More)
Two aberrant rami originating from the right transverse cervical nerve and innervated the midportion of the sternocleidomastoid muscle (SM) were detected during routine cadaver dissection. Although SM is commonly innervated by the accessory nerve, as well as by cervical nerves, it is likely to be innervated additionally by other nerves such as hypoglossal(More)
Anatomical variations of the hepatic arteries are not uncommon. The anomalous hepatic arterial supply is of paramount importance in hepatobiliary, pancreatic or liver transplantation and in laparoscopic surgery. We describe an unusual case of a 66-year-old Greek male cadaver, where a rare anastomosis (in the form of an enlarged arterial loop, 4.84 mm in(More)
