Intraosseous malignant peripheral nerve sheath tumor at the frontal bone in a child: a rare cause of proptosis.

We report a nine-year-old male having malignant peripheral nerve sheath tumor (MPNST) of the frontal bone, represented with a twelve-month history of ptosis and proptosis in his right eye and enlarged rapidly in the last three months. Except for slight numbness at his one-third of the right forehead, he had no neurological deficit. The patient's both eyes were having normal eye movements, and he had no visual acuity or field loss.

Yalçın K, Tüysüz G, Kazan S, Gürer Eİ, Karaali K, Küpesiz A, Güler E. An infant with intradural extramedullary synovial sarcoma: the youngest case in the literature. Turk J Pediatr 2019; 61: 765-770.

Deep palmar tumorous conditions of the hand.

Purpose: Deep palmar tumors of the hand are very rare, and reported cases are usually benign. The most important issue is frequent anatomical variations with challenging surgical exposure and excision of these lesions. Some case reports or a small series of patients have been reported in the literature.

Tumorous Conditions of the Hand: A Retrospective Review of 402 Cases.

Objective: Knowledge concerning treatment and care of hand lesions is often based on small case series, case reports and a few large general case series. The aim of this study is to present our experience with hand tumors' and tumor-like lesions' incidence, age range and localizations.

Material And Method: Between 2006-2016, 402 patients operated and histopathologically diagnosed with bone and soft tissue tumorous conditions of the hand were evaluated retrospectively.

Extensive ameloblastic fibroma of the mandibula in a female adult patient: A case report with a follow-up of 3 years.

Ameloblastic fibroma (AF) is rare benign odontogenic tumour which usually occurs in the first two decades of life. It can occur either the mandible or maxilla but it is most frequently found in the posterior region of the mandible. Treatment of AF in usual is a conservative approach, such as enucleation and curettage but the aggressive lesions require a radical approach.

Epidural capillary hemangioma: A review of the literature.

Hemangiomas in the spinal epidural area are very rare lesions, and most of these lesions are of the cavernous type. Only seven cases of capillary hemangiomas have been reported in the English literature, and all of these cases occurred in adulthood. Here, we report on a 17-month-old girl who presented with an inability to walk.

Intra-operative brain tumor detection using elastic light single-scattering spectroscopy: a feasibility study.

We have investigated the potential application of elastic light single-scattering spectroscopy (ELSSS) as an adjunctive tool for intraoperative rapid detection of brain tumors and demarcation of the tumor from the surrounding normal tissue. Measurements were performed on 29 excised tumor specimens from 29 patients. There were 21 instances of low-grade tumors and eight instances of high-grade tumors.

Burkitt's lymphoma following a pediatric liver transplantation: predictive negative value of serologic response to Epstein-Barr virus.

Post-transplant lymphoproliferative disorder (PTLD) represents a spectrum of Epstein-Barr virus (EBV)-related clinical diseases, from a benign mononucleosis-like illness to a fulminant non-Hodgkin's lymphoma. Because a large proportion of children are seronegative at the time of transplantation, recipients are at high risk of contracting primary EBV infection and subsequently developing PTLD. Surveillance techniques with antibody titers and/or polymerase chain reaction (PCR) may have a role in some high-risk settings.

Angiolipoma located inside the obturator canal and supplied by the umbilical artery.

During dissection of the retropubic region of a 55-year-old female cadaver, we encountered an angiolipoma located inside the obturator canal which was connected to the wall of the urinary bladder by a fibrous cord. The angiolipoma was supplied by a branch originating from the umbilical artery. Microscopically the benign soft tissue tumor was characterized by lobules of mature adipocytes and densely distributed networks of small and larger blood vessels, thus resembling typical histological features of an angiolipoma.

Effects of intrathecal administration of FK506 after sciatic nerve crush injury.

Although various administration routes of FK506 have been published, intrathecal administration of FK506 has not previously been reported in the literature. A daily dose of 0.05 mg/kg of FK506 was given (a small dose compared with those reported in the available literature).

Detrimental effects of immobilization on functional recovery after sciatic nerve crush.

Peripheral-nerve trauma has been a challenge to surgeons, with significant advances in the surgery of repair. Immobilization of the injured limb after repair has been the traditional method of treatment. Although peripheral-nerve regeneration has been studied extensively, the correlation between functional recovery and the immobilization period has not been well-documented.
