Follicular dendritic cell sarcoma presenting as a thyroid mass: an unusual case report and literature review.

Thyroid follicular dendritic cell sarcoma (FDCS) is an extremely rare malignancy that originates from follicular dendritic cells of the germinal centers and is characterized by the neoplastic proliferation of spindled to ovoid cells. As there have been only five cases reported in the literature until now, the diagnostic and therapeutic information available to clinicians regarding thyroid FDCS is fairly limited. To our knowledge, this is the first case report of thyroid FDCS without a history of Hashimoto's thyroiditis.

Case Series on Four Treated Cases of Embryonal Rhabdomyosarcoma in Children.

We report four cases of embryonal rhabdomyosarcoma treated successfully with multimodality therapy which included surgery, chemotherapy and radiotherapy. Our first case was a 2 year old who admitted with the chief complaint of swelling of the upper lip. Biopsy was taken, which showed embryonal rhabdomyosarcoma.

Chiari type I malformation: role of the Chiari Severity Index and Chicago Chiari Outcome Scale.

Objective: The authors aimed to determine whether the Chiari Severity Index (CSI), and other clinical variables, can be used as a predictor of postoperative outcomes for Chiari type I malformation (CM-I) using the modified Chicago Chiari Outcome Scale (mCCOS) as the postoperative measure.

Methods: The cohort included patients 18 years of age and younger who were treated for CM-I between 2010 and 2015 who had at least 12 months of clinical and radiographic follow-up. CSI grades were assigned using preoperative clinical and neuroimaging data.

Clipping of Complex Internal Cerebral Artery Terminus Aneurysm: 2-Dimensional Operative Video.

Internal carotid artery (ICA) bifurcation, or terminus, aneurysms are uncommon, and although they can be accessed with relative ease, clip occlusion of such aneurysms is often challenging due to the close proximity of basal forebrain perforator vessels. This patient had an incidentally discovered ICA terminus aneurysm and elected for microsurgical clipping. A modified orbitozygomatic approach was used to approach the aneurysm.

Primary squamous cell carcinoma (PSCC) of the thyroid: a case report and review of the literature.

Primary squamous cell carcinoma (PSCC) is a rare neoplasm of the thyroid with a very poor prognosis. We report a case of a 42-year-old woman with occasionally found mass in the right anterior area of the neck. After a total thyroidectomy, histopathology and immunohistochemistry tests confirmed primary squamous cell carcinoma of the thyroid with the exclusion of all other possible primary tumor locations.

Impact of Radiotherapy on Neck Dissection Nodal Count in Patients With Head and Neck Cancer.

Objectives/hypothesis: Our study aimed to review the impact of preoperative radiotherapy (RT) and other factors on the lymph node count of neck dissection (ND) specimens from patients with head and neck cancer (HNC). A retrospective study was conducted on all patients with head and neck cancers who had undergone NDs in Singapore General Hospital between 1992 and 2013.

Study Design: Retrospective study.

Radiological approach for the newly incorporated T staging factor, depth of invasion (DOI), of the oral tongue cancer in the 8th edition of American Joint Committee on Cancer (AJCC) staging manual: assessment of the necessity for elective neck dissection.

The 8 edition of American Joint Committee on Cancer's (AJCC) Cancer Staging Manual was modified by incorporating depth of invasion (DOI) in the T categorization of oral cavity cancer. This is because DOI is strongly associated with cervical lymph node metastasis, which is the most important negative prognostic factor of oral cavity cancer. This major change in the AJCC Cancer Staging Manual caused re-staging of T category in several cases.
