OBJECTIVE: Neurofibromatosis type 1 (NF1) is a multisystemic genetic disease in which patients develop benign tumors including optic nerve gliomas (ONG). Optic nerve thickening and tortuosity are radiologic markers of tumors but can also be present in children with NF1 who do not have gliomas, thus complicating screening and diagnosis. We undertook this study to retrospectively determine quantitative and qualitative diagnostic criteria using MRI of the orbits for ONG in children with NF1...

Traumatic brain injury (TBI) is a leading cause of mortality and disability worldwide. Although treatment guidelines have been developed, no best treatment option or medicine for this condition exists. Recently, mesenchymal stem cells (MSCs)-derived exosomes have shown lots of promise for the treatment of brain disorders, with some results highlighting the neuroprotective effects through neurogenesis and angiogenesis after TBI. However, studies focusing on the role of exosomes in the early stages of neuroinflammation post-TBI are not sufficient...

Basal cell carcinoma (BCC) occurs preferentially on the face. We retrospectively analyzed 200 cases of BCC treated at Nagoya City University Hospital from April 2004 to October 2015 and examined regional features based on modified facial aesthetic units. BCC occurred more frequently on the cheek, nasal and orbital areas. There was no significant difference between sides, and age was the only factor affecting tumor size.

The aim of the present study was to describe a rare case of orbital precursor B-lymphoblastic lymphoma (B-LBL) in an adult. A 56-year-old male in complete remission of a gastric precursor B-LBL was referred to our orbital clinic due to rapid development of left-sided painless periorbital swelling, diplopia, and proptosis. Complete ophthalmoplegia was observed. Notably, magnetic resonance imaging showed swelling of the medial and inferior rectus muscles in the left orbit and biopsies were performed. Following histological diagnosis of precursor B-LBL, the patient was treated with radiotherapy (2Gy × 20) and chemotherapy according to the NOPHO ALL 2008 protocol...

BACKGROUND: The endoscopic endonasal approach is a surgical alternative for midline anterior skull base tumors. A detailed understanding of the proximal anterior cerebral artery (ACA) branches' anatomy from an endonasal perspective is essential for avoiding vascular complications. OBJECTIVE: To evaluate, from an endonasal perspective, the anatomic variations of the ACA and its proximal branches, specifically the recurrent artery of Heubner (RAH), and the fronto-orbital (FOA) and frontopolar (FPA) arteries...

The management of patients with diffuse invasive conjunctival melanoma focuses on local tumor control and screening for metastasis. Despite the lack of consensus on the benefit of sentinel lymph node biopsy for these neoplasms, the information obtained by histopathology is useful for tumor staging and treatment planning. Due to the lack of evidence of survival improvement, orbital exenteration is being performed with diminishing frequency. We describe a patient with diffuse invasive conjunctival melanoma and lymph node involvement treated by tumor debulking, brachytherapy (custom unshielded radioactive device), and adjuvant ipilimumab who has had a favorable outcome without emergence of local tumor relapse or distant metastasis during 16 months of follow up...

Primary cutaneous angiosarcoma is a rare vasoformative malignant neoplasm that can present a diagnostic and therapeutic challenge. We describe a 76-year-old Caucasian man with right upper eyelid swelling and nodularity, initially suspected clinically to represent either ocular adnexal lymphoma or basal cell carcinoma. Incisional biopsy and wide resection of the mass with frozen section control of margins were interpreted as compatible with hobnail (Dabska-retiform) hemangioendothelioma. Foci of atypia were noted in the tumor, raising speculation of evolution into a more aggressive neoplasm, such as conventional angiosarcoma...

OBJECTIVE: In the case of deep invasion of an infratemporal fossa (ITF) tumor, surgeons find it difficult to gain sufficient visualization and working space by conventional surgical approaches. To overcome these limitations, we have developed a novel surgical technique, maxillo-orbito-zygomatic (MOZ) approach, by combining partial lateral maxillectomy with the conventional orbito-zygomatic approach. METHODS: A 63-year-old male presented with the fifth recurrent adenoid-cystic carcinoma in the right deep ITF...
