Purpose: Cranial fasciitis is a rare type of benign tumor that occurs mostly in children younger than 6 years. It arises from the deep fascia, periosteum, or fibromembranous layer that covers fontanelles. The etiology is unknown, although prior trauma has been postulated to be an underlying cause. There is a 2:1 male predominance. Despite its rapid growth, this tumor has a benign clinical course and can be cured by total excision. Methods: A 16-year-old male presented with a 3 cm-sized palpable mass in the left lateral eyebrow region that he first noticed 4 months before presentation. The mass had grown rapidly since it was first noticed. Preoperative brain computed tomography showed a well-demarcated mass approximately 3 cm in size extending from the subcutaneous layer to the periosteum. Preoperatively, the presumed diagnosis was a dermoid cyst. An operation was performed with the patient under general anesthesia. The subcutaneous mass was completely excised by periosteal dissection. Results: Histological diagnosis revealed the presence of cranial fasciitis. After 20 months of follow-up, there have been neither complications nor evidence of local recurrence besed on clinical examination. Conclusion: Although cranial fasciitis is quite rare, it should be considered in the differential diagnosis for lytic skull lesions in patient whose clinical presentation suggests this possibility. This condition could be occasionally mistaken for malignant or locally aggressive lesions. To prevent local recurrence, curettage of the underlying bone is recommended for patients with bone involvement.

A 60 years old female patient presented with $8{\times}6\;cm$ sized painless oval mass in the left parietal region. She had left lobectomy of thyroid gland 10 years ago. Cranial CT, MRI, FGD PET-CT showed a solid mass which invaded left parietal bone. After embolization, craniectomy with tumor excision was performed. Histological examination revealed metastatic follicular cancer originated thyroid gland, with vascular and dura invasion. Postoperatively, neck CT showed right thyroid multiple nodules and right level III multiple lymph node enlargement. Thyroid function test was normal, but level of thyroglobulin was high (72ng/ml). So she had right lobectomy of thyroid gland with lymph node dissection under a diagnosis of follicular carcinoma. But histological examination revealed adenomatous hyperplasia and not lymph node metastasis. After operation, she received radioiodine therapy of 150mCi and then the level of thyroglobulin normalized (8.4ng/ml). The patient is under follow-up since she had operation 4 months ago.

There are some difficulties in approaching and removing the lesion in infratemporal fossa because of its anatomical location. After wide excision of tumor lesion, it is also difficult for reconstruction of mandibular condyle and cranium base on infratemporal fossa. Besides, there are some possibilities of cerebrospinal fluid leakage, intracranial infection and bone resorption. It is also challenging for functional reconstruction that allows normal mandibular movement, preventing mandibular condyle from invaginating into the skull. In this report, we present 14-month follow-up results of a patient who had undergone posterior segmental mandibulectomy including condyle and infratemporal calvarial bone and mandible reconstruction with free vascularized costochondral rib and calvarial bone graft to restoration of the temporomandibular joint area.

In this study, we aimed to investigate the neuroprotective effects of caffeic acid phenethyl ester (CAPE), an active component of propolis purified from honeybee hives, on photothrombotic cortical ischemic injury in mice. Permanent focal ischemia was achieved in the medial frontal and somatosensory cortices of anesthetized male C57BL/6 mice by irradiation of the skull with cold light laser in combination with systemic administration of rose bengal. The animals were treated with CAPE (0.5-5 mg/kg, i.p.) twice 1 and 6 h after ischemic insult. CAPE significantly reduced the infarct size as well as the expression of tumor necrosis $factor-{\alpha}$, hypoxiainducible $factor-1{\alpha}$ monocyte chemoattractant protein-1, $interleukin-1{\alpha}$, and indoleamine 2,3-dioxygenase in the cerebral cortex ipsilateral to the photothrombosis. Moreover, it induced an increase in heme oxygenase-1 immunoreactivity and interleukin-10 expression. These results suggest that CAPE exerts a remarkable neuroprotective effect on ischemic brain injury via its anti-inflammatory properties, thereby providing a benefit to the therapy of cerebral infarction.

Multiple myeloma is a malignant plasma cell tumor that is thought to originate proliferation of a single clone of abnormal plasma cell resulting production of a whole monoclonal paraprotein. The authors experienced a case of multiple myeloma with severe mandibular osteolytic lesions in 46-year-old female. As a result of careful analysis of clinical, radiological, histopathological features, and laboratory findings, we diagnosed it as multiple myeloma, and the following results were obtained ; 1. Main clinical symptoms were intermittent dull pain on the mandibular body area, abnormal sensation of lip and pain due to the fracture on the right clavicle. 2. Laboratory findings revealed M-spike, reversed serum albumin-globulin ratio, markedly elevated ESR and hypercalcemia. 3. Radiographically, multiple osteolytic punched-out radiolucencies were evident on the skull, zygoma, jaw bones, ribs, clavicle and upper extremities. Enlarged liver and increased uptakes on the lesional sites in RN scan were also observed. 4. Histopathologically, markedly hypercellular marrow with sheets of plasmoblasts and megakaryocytes were also observed.

Osteoma is one of the benign tumor that occurs on the bones all over the body. Mostly the simple excision is known to be enough. However, sometimes we encounter the troublesome situation where the osteoma is located in very challenging area, which results in the recurrence. 26 year female presented with the intractable intracranial osteoma. Given the disease entity of the osteoma, the simple excision would be enough or conservative management. But this osteoma turned out to be huge and recurrent in spite of the endoscopic resections, which causes the facial disappearance accompanied by the orbital vertical dystopia. Moreover, the patient's main concern was the pain. We performed the intracranial resection of the whole lesion and reconstructed the skull base and frontal bone as well as the part of the orbital wall. In order to restore the original bony anatomy, the 3D printing model was used based on the titanium mesh. I report this unusual case of the intractable intracranial huge osteoma. This report may be helpful for the other surgeons to make a decision on their similar cases in the future.

A rare case of telangiectatic osteosarcoma of the sphenoid bone was reported. The patient was a 27-year-old male and had suffered from left eye protrusion and diplopia for three months. Radiologically, a lobulated osteolytic lesion was located between sphenoid and left temporal bone. Pathologically, the tumor had multiloculated blood filled cystic vascular spaces and osteoid formation by malignant spindle osteoblast cells. The differential diagnosis of this rare entity from aneurysmal bone cyst was important radiologically and pathologically. This case is the second case of telangiectatic osteosarcoma of the sphenoid bone followed by a case of Whitehead RE and Melhem ER in 1998.

A 6-year-old spayed female Turkish Angora cat presented with sneezing, nasal discharge, and decreased appetite lasting for 21 days. Skull radiography revealed slightly increased density of soft tissue in the left nasal cavity. Computed tomography (CT) scan revealed an extensive mass with nasal septum destruction and moderate contrast enhancement in the left nasal cavity. After surgical biopsy, histopathological examination confirmed that the mass was an infiltrative round cell neoplasm, composed of sheets of large neoplastic cells. Immunohistochemical analysis revealed that most of the neoplastic cells were strongly positive for CD79a and weakly positive for PAX5. Additionally, numerous mature lymphocytes were found to be positive for CD3. This is the first reported case of nasal diffuse large B-cell lymphoma (DLBCL) in a Turkish Angora cat in Korea.

Solitary extramedullary plasmacytomas are isolated plasma cell tumors of soft tissue that typically do not metastasize. They are rare and account for 4% of all plasma cell tumors. To our knowledge, only 14 cases of solitary extramedullary plasmacytomas in the sphenoid sinus have been reported. A 32-year-old man presented to our department with complaint of ocular pain in the right eyeball and diplopia. Physical and neurological examinations revealed intact and prompt direct and indirect light reflexes in both pupils and limitation of extraocular muscle movement seen with the lateral gaze of the right eyeball. Magnetic resonance imaging suggested the presence of mucocele or mycetoma, therefore surgical resection was performed with endoscopic endonasal transsphenoidal approach. Histopathology was consistent with plasmacytoma. Systemic work-up did not show any evidence of metastasis and the sphenoid sinus was the sole tumor site, and therefore the diagnosis of solitary extramedullary plasmacytoma was confirmed. We report a rare case of solitary extramedullary plasmacytoma in the sphenoid sinus with successful treatment using the endoscopic endonasal transsphenoidal resection and adjuvant radiotherapy.

Background: The aim of this study was to analyze the clinicopathological and immunohistochemical features of primary central nervous system lymphoma (PCNSL) cases occurring in Indian patients and also study the utility of the crush smear preparation in intraoperative diagnosis. Materials and Methods: The immune status, clinical, radiological details, immunohistochemical profile, histopathological findings and cytological features in smear preparation of 32 cases of PCNSL were analyzed. Patients with systemic NHL and skull-base lymphomas were excluded. Results: The mean age of our patients was 52 years with a male: female ratio 1:1. A periventricular location was found in 62.5% of patients. None of our PCNSL cases were associated with AIDS. All cases except one were diffuse large B-cell lymphomas. Intraoperative diagnosis using crush smears allowed correct prediction in 93% of cases. Conclusions: Our study shows that PCNSL is seen predominantly in immunocompetent patients in India. The age of presentation is relatively young as compared to the West. Our study also stresses the utility of crush smear preparation in establishing an intraoperative diagnosis.
