Central nervous system[CNS] involvement of acute lymphoblastic leukemia may occur. However, CNS involvement as a first manifestation of leukemia is very rare. An 8-year-old girl complained of a backache after playing in the water. Neurological examination detected progressing paraparesis. Magnetic resonance imaging[MRI] of the thoracolumbar spine showed a well-circumscribed homogeneous posterior extradural mass lesion extending from T7 to T9. MRI of the brain showed diffused fatty marrow replacement of the calvarium and the skull base. We report a patient with epidural Burkitt's lymphoma of the thoracic and lumbar vertebra causing compression of the spinal cord after pathologic evaluation. The tumor consisted mainly of lymphoblastic cells, which were identical to those originally seen in the bone marrow aspiration and biopsy. After decompressive laminectomy she began consolidation chemotherapy.

Primary intracranial malignant melanoma is a very rare and highly aggressive tumor with poor prognosis. A 66-year-old female patient presented a headache that had been slowly progressing for several months. A large benign pigmented skin lesion was found on her back. A brain MRI showed multiple linear signal changes with branching pattern and strong enhancement in the temporal lobe. The cytological and immunohiostochemical cerebrospinal fluid examination confirmed malignant melanoma. A biopsy confirmed that the pigmented skin lesion on the back and the conjunctiva were benign nevi. We report a case of primary intracranial malignant melanoma and review relevant literatures.

Supratentorial dermoid cysts are uncommon to develop in the cavernous sinus. We present a ruptured dermoid cyst of the cavernous sinus extending into the posterior fossa. The patient was a 32-year-old female who complained occipital headache, blurred vision, and tinnitus over 4 years. Brain magnetic resonance (MR) imaging revealed an enhanced tumor in the right cavernous sinus extending into the right temporal base and the posterior fossa with findings of ruptured cyst. Surgical resection was performed, and pathological findings were confirmed to be a dermoid cyst. We report a second case with ruptured dermoid cyst of the cavernous sinus extending into the posterior fossa.

Renal cell carcinoma is the third most common metastatic tumor to the bone and soft tissues of the head and neck. The common sites of metastatic renal cell carcinoma in head and neck region are nasal cavity, paranasal sinuses, oral mucosa, gingiva, tongue, palate, lip as the favored site. The present paper deals with one patient with metachronous oral tongue, nasal cavity and suspicious brain metastases after 2 years of renal cell carcinoma nephrectomy. Also, the patient had history of total thyroidectomy for thyroid follicular carcinoma. Total excision of nasal cavity and tongue mass were performed. Therapeutic aspects are briefly reviewed in literature.

The aim of this study was to investigate the anti-inflammatory and anti-oxidant activity of Ligularia fischeri leaf extract on adjuvant induced arthritis in experimental mice. The oral administration of the L. fischeri leaf extract (LF), at doses of 100 and 200 mg/kg body weight once a day for 3 weeks, significantly reduced hindpaw swelling and the production of inflammatory cytokines (tumor necrosis factor(TNF)-${\alpha}$, interleukin(IL)-$1{\beta}$, and IL-6). Treatment with LF (100 mg/kg) also decreased the serum levels of triglyceride and low density lipoprotein(LDL)-cholesterol, and increased high density lipoprotein(HDL)-cholesterol contents compared with those of a control group. The induction of arthritis significantly increased oxidized proteins such as protein carbonyl, advanced oxidation protein products, and advanced glycation end-products in the lung, heart, and brain. Treatment with LF for 3 weeks reduced the levels of oxidized proteins. These results suggest that L. fischeri extract might be beneficial in the treatment of chronic inflammatory disorders.

Cancer-testis antigens (CTAs) are a group of tumor-associated antigens with more than 140 members whose expression has been shown to be limited to gametogenic tissues and placenta among normal tissues. However, malignant tissues of different origins have shown aberrant and elevated expression of these antigens. Such a pattern of expression endows beneficial properties for use as cancer biomarkers as well as immunotherapeutic targets as a result of the immune-privileged status of the testes. CTAs have been shown to be expressed in pediatric brain tumors, different types of sarcomas, leukemias, and lymphomas as well as neuroblastomas. Although data regarding their expression pattern in childhood tumors are not as comprehensive as for adult tumors, it is supposed that CTA-based immunotherapeutic approaches can also be used for pediatric cancers. However, there are limited data about the objective clinical responses following immunotherapy in such patients. Here we try to review the available information.

We present a case of olfactory schwannoma in a 16-year-old boy with headache and diplopia. Brain computed tomography[CT] scan and magnetic resonance[MR] imaging showed a huge mass in the subfrontal area resembling an olfactory groove meningioma. We performed a bifrontal craniotomy and found out the mass was attached to cribriform plate but was not related to the olfactory tract or bulb. The histopathological diagnosis of schwannoma was confirmed by immunohistochemical staining for S-100, vimentin and others. We describe the clinical manifestations, radiological characteristics, histological aspects, and differential diagnosis of this tumor with literature review.

Germinoma is a rare central nervous system neoplasm in children and young adults. It is well known that a malignant primary neoplasm can be cured by conventional radiation therapy alone or reduced-volume and field irradiation in combination with chemotherapy. The authors report a very rare case of a pineal germinoma, which was completely disappeared after repeated diagnostic brain computed tomography(CT) with review of pertinent literature. There has been neither tumor recurrence nor metastasis during follow-up period.
