Low-grade sinonasal non-intestinal-type adenocarcinoma: a rare case report and literature review.

Sinonasal non-intestinal-type adenocarcinoma is a rare but important differential diagnosis in patients presenting with recurrent, unexplained epistaxis. Low-grade types have a more favourable prognosis as opposed to the more aggressive high-grade. Symptoms include nasal obstruction and epistaxis that can last up to 5 years.

Primary leiomyosarcoma of the thyroid with concurrent papillary thyroid cancer: a rare case report and a review of literature.

Background: Leiomyosarcoma (LMS) is a soft tissue malignant tumor that has a predilection to the abdominopelvic and limb smooth muscles. LMS of the thyroid is exceptionally rare. Papillary thyroid cancer (PTC) is the most common thyroid malignancy and originates from the thyroid epithelial layer.

Concurrent Warthin tumor and Kimura disease: a case report.

Background: Warthin tumor (WT) is a common benign salivary tumor of the parotid gland. Clinically, it occurs in men in their fifth to seventh decades who typically smoke cigarettes. WTs have been reported with different head and neck neoplasms and other salivary gland tumors within the same or another salivary gland.

Low-Grade Fibromyxoid Sarcoma Featuring an Unusual Gene Fusion: Report of a Rare Case Arising in the Parotid Gland.

Low-grade fibromyxoid sarcoma (LGFMS), also known as Evan's tumor, is a fibroblastic tumor with a deceptively bland morphology but a high metastasizing potential and late recurrence. It presents clinically as a slowly growing mass in the deep soft tissue of extremities and trunk. Morphologically, it shows a biphasic pattern with alternating fibrous and myxoid areas, whorling growth pattern, hypocellularity, and bland fibroblasts with curvilinear or arcuate vessels in between.

Pyogenic granuloma of the larynx.

Pyogenic granulomas are benign, typically painless, vascular tumors of the skin and mucosal surface. Recently the term 'lobular capillary hemangioma' has been introduced to describe the histological appearance more accurately. Major locations for pyogenic granuloma are in the head and neck region, but larynx localization is rare.

The Prediction of Malignancy Risk in Thyroid Nodules Classified as Bethesda System Category III (AUS/FLUS) and the Role of Ultrasound Finding for Prediction of Malignancy Risk.

Objective To predict the risk of malignancy in category III of the Bethesda System for Reporting Thyroid Cytopathology "Atypia of Undetermined Significance/Follicular Lesion of Undetermined Significance (AUS/FLUS)" at King Abdulaziz Medical City, Riyadh, Saudi Arabia. It also intends to determine other possible contributing predictors of malignancy in thyroid nodules such as age, sex, and ultrasound (US) findings. Method This retrospectively designed study included 187 patients (mean age, 43.

Frontal sinus inverted papilloma managed with Draf III.

Inverted papilloma (IP) is a rare benign tumor that originates from nasal and paranasal sinus mucosa. Although it is considered a benign lesion, it is locally aggressive and has risk between 7 and 15% for malignant transformation. The management of frontal sinus (FS) IP is still challenging due to its rarity and local invasiveness.

Endoscopic ultrasound guided fine-needle aspiration vs core needle biopsy for solid pancreatic lesions: Comparison of diagnostic accuracy and procedural efficiency.

Background: Endoscopic ultrasound (EUS) guided core needle biopsies (CNB) are increasingly being performed to diagnose solid pancreatic lesions. However, studies have been conflicting in terms of CNB improving diagnostic accuracy and procedural efficiency vs fine-needle aspiration (FNA), which this study aims to elucidate.

Methods: Data were prospectively collected on consecutive patients with solid pancreatic or peripancreatic lesions at a single tertiary care center from November 2015 to November 2016 that underwent either FNA or CNB.

Unexpected endometrial metastasis of a primary lung adenocarcinoma.

Following diagnosis of primary malignancies, subsequent workup includes evaluation for metastasis. Each malignancy, both location and histologic features, have statistically common and less common metastatic patterns. Metastatic lung adenocarcinoma typically involves lymph nodes, liver, brain, and bone.

The Importance of High-Risk Human Papillomavirus Types Other Than 16 and 18 in Cervical Neoplasia.

Context: - Types 16 and 18 are the most widely studied high-risk types of human papillomavirus (HPV). However, other high-risk HPV types (HPV non-16/18) also play a significant role in cervical neoplasia. Currently, screening and management algorithms separate out HPV 16/18 from all other HPV non-16/18 types.

Fibroepithelial Stromal Polyp of the Vulva: Case Report and Review of Potential Histologic Mimickers.

Vulvar tumors arising from submucosal connective tissue, some of which exhibit hormonal responsiveness, have many clinical and histologic overlapping characteristics. We present a case of a fibroepithelial stromal polyp arising from the vulva of a 22-year-old female. We review the differential diagnosis with an emphasis on distinguishing features of these uncommon neoplasms.

Cost-effectiveness of Gene Expression Classifier Testing of Indeterminate Thyroid Nodules Utilizing a Real Cohort Comparator.

Objective To predict the cost-effectiveness of implementing routine gene expression classifier testing for thyroid nodules with indeterminate fine-needle aspiration cytology, by utilizing a real cohort of patients as a comparator. Study Design Cost-effectiveness analysis of a retrospective cohort compared with a simulated cohort. Setting Tertiary academic medical center.
