Solitary epithelioid hemangioendothelioma of the metacarpal.

Hemangioendotheliomas are vascular tumors which have an intermediate clinical behavior between hemangiomas and angiosarcomas. The epithelioid subtype of hemangioendothelioma, which is rarely seen in bone, has the potential to metastasize and may be confused radiologically with benign or malignant lesions. A metacarpal origin of this tumor is extremely rare.

The presence of Epstein-Barr virus (EBV) in diffuse large B-cell lymphomas (DLBCLs) in Turkey: special emphasis on 'EBV-positive DLBCL of the elderly'.

Accumulated evidence has shown the importance of Epstein-Barr virus in the pathogenesis of various lymphomas. This study aimed to determine the prevalence of Epstein-Barr virus expression and its effect on survival amongst diffuse large B-cell lymphoma (DLBCL) cases from two large tertiary care centres in Turkey with a particular interest in identifying cases of 'Epstein-Barr virus-positive DLBCL of the elderly'. Diffuse large B-cell lymphoma cases diagnosed between 1999 and 2009 were retrieved and 340 cases were used to construct tissue microarrays.

Primary apocrine adenocarcinoma of the scrotum with distant metastasis: a case report.

A 53-year-old man presented with weakness, loss of weight, pain in upper and lower extremities, and back pain. He had an intermittent abscess like discharge from a left hemi scrotal lesion. Thoraco abdomino pelvic computerized tomography revealed diffuse, multiple and hypodense lesions in the liver parenchyma.

Benign multicystic peritoneal mesothelioma.

Benign multicystic peritoneal mesothelioma is a rare tumor that occurs mainly in women in their reproductive age. It is characterized by the formation of multiple, thin-walled, multilocular cysts that frequently produce large, intra-abdominal masses. The short follow-ups and possible etiologies based on the published reports make it difficult to draw any firm conclusions.

Cellular schwannoma of the greater superficial petrosal nerve presenting with abducens nerve palsy and xerophthalmia: case report.

Objective: Cellular schwannomas (CS) are rare in the cranial space. This report is the first of a patient with a greater superficial petrosal nerve CS presenting with abducens nerve palsy and xerophthalmia.

Clinical Presentation: A 16-year-old female patient presented with a 1-month history of diplopia.

Ultrastructure protection and attenuation of lipid peroxidation after blockade of presynaptic release of glutamate by lamotrigine in experimental spinal cord injury.

Object: Lamotrigine is an antiepileptic drug that inhibits presynaptic voltage-gated sodium channels and reduces the presynaptic release of glutamate in pathological states. Neuroprotective effects of this drug have already been demonstrated in cerebral ischemia models. The aim of the present study was to determine the effects of presynaptic glutamate release inhibition on experimental spinal cord injury (SCI).

Metastatic malignant melanoma of the uterine cervix: first diagnosed on liquid-based cytology.

Malignant melanomas of the female genital tract are uncommon lesions. The first case of vulvar melanomas with a subsequent malignant melanoma of the cervix diagnosed based on liquid-based cytology without evidence of gross pathology is described.

Histopathological parameters with Ki-67 and bcl-2 in the prognosis of meningiomas according to WHO 2000 classification.

Aims And Background: Meningiomas are classified following the WHO system of 2000 into three grades, benign (grade I), atypical (grade II), and anaplastic (grade III). We investigated the relation between tumor grade and Ki-67 and bcl-2.

Methods: In the present study, 246 cases of meningioma were reclassified according to the WHO 2000 system.

Primary ovarian leiomyosarcoma: a review of the clinical and immunohistochemical features of the rare tumor.

Unlabelled: Primary pure ovarian leiomyosarcomas constitute a malignant subgroup of ovarian smooth muscle tumors which comprise only 1% of ovarian tumors. Their origin, etiology, histologic features, clinical behavior, and optimal treatment are still obscure. Malignant behavior is almost always associated with any 2 of coagulative necrosis, cellular atypia, and mitotic index greater than 10.

Surgical conservation of both ovaries in an adolescent with uterine müllerian adenosarcoma: a case report.

Fertility-sparing and minimally invasive surgeries are advancing everyday in gynecologic oncology. However, data on conservation of ovaries in uterine müllerian adenosarcoma are limited due to its very rare incidence in reproductive-aged females. Conservation of both ovaries along with adjuvant chemotherapy was performed in a 14-year-old girl with uterine adenosarcoma.

Rapid communication: renal apoptosis after shockwave application in rabbit model.

Purpose: To identify any apoptotic effect of shockwave lithotripsy (SWL) on renal tubular and glomerular cells.

Materials And Methods: Thirty-five male New Zealand White rabbits were divided into five groups of seven rabbits each: I (control), II (sham), and III, IV, and GV (treated and sacrificed 1, 7, and 28 days after SWL, respectively). Intramuscular anesthetic agent (ketamine HCl; 20 mg/kg) and intravenous contrast medium (iohexol 300 mg of I/mL) were administered to animals in group II.

Epithelioid sarcoma-like hemangioendothelioma: a case report.

Seven cases of an unusual low-grade vascular tumor were reported in a recent study. Despite its similarity to epithelioid sarcoma, this tumor was termed epithelioid sarcoma-like hemangioendothelioma because of the subtle histopathological and immunohistochemical differences. Another case of this rare entity in a 70-year-old woman who suffered from a painful mass on the anterior aspect of the right cubital fossa is presented here, together with a review of the relevant literature.

Split-cord malformation and tethered cord associated with immature teratoma.

Case Report: We report a case of a 12-month-old boy with split-cord malformation, tethered cord, and intradural immature teratoma containing immature nephroblastic tissue. He also had a horseshoe kidney.

Outcome: Surgical removal of the teratoma and tethered cord resulted in functional improvement of the existing bladder dysfunction.

Monostotic fibrous dysplasia of the thoracic spine: clinopathological description and follow up. Case report.

The authors report the case of a 53-year-old woman with monostotic fibrous dysplasia of the thoracic spine. The patient presented with a 1-month history of pain in the thoracic spinal region. En bloc resection of the lesion was successfully performed via a transthoracic approach, and a histopathological examination confirmed the diagnosis of fibrous dysplasia.
