Free temporalis muscle fascia graft in dural reconstruction following surgical resection of intermediate and malignant skull base tumors: A 10-year experience from a single center.

Background: Data from patients with post-ablative dural defects reconstructed using a free temporalis muscle fascia graft (FTFG) after resection of anterior or central skull base tumors were retrospectively analyzed.

Methods: The primary predictor and outcome variables were the reconstructive methods for dural repair and postoperative cerebrospinal fluid (CSF) leakage rate, respectively.

Results: Eighty patients were included, and 94 postoperative dural reconstructions were performed using FTFG.

An unusual case of hyalinizing clear cell carcinoma in a sinonasal cavity and cranial base.

Hyalinizing clear cell carcinoma (HCCC) is a rare, predominantly minor salivary gland tumor. Most of these tumors occur in the oral cavity, mainly the palate and tongue. Primary localization of the tumor in the region of the nasal cavity and paranasal sinuses is extremely rare and, with only a few cases reported in the literature so far.

Upper neck papillary thyroid cancer (UPTC): A new proposed term for the composite of thyroglossal duct cyst-associated papillary thyroid cancer, pyramidal lobe papillary thyroid cancer, and Delphian node papillary thyroid cancer metastasis.

Objectives/hypothesis: Thyroglossal duct cyst (TGDC) is a common congenital anomaly, but TGDC carcinoma is rare. Thyroglossal duct cyst carcinoma management is controversial, especially that of the orthotopic thyroid gland. We aim to provide an insight into the pathologic basis of this management controversy through the review of 28 TGDC cancer cases, thus far the largest such series to our knowledge.
