A model for classification of invasive fungal rhinosinusitis by computed tomography.

Our purpose was to classify acute invasive fungal rhinosinusitis (AIFR) caused by Mucor versus Aspergillus species by evaluating computed tomography radiological findings. Two blinded readers retrospectively graded radiological abnormalities of the craniofacial region observed on craniofacial CT examinations obtained during initial evaluation of 38 patients with eventually pathology-proven AIFR (13:25, Mucor:Aspergillus). Binomial logistic regression was used to analyze correlation between variables and type of fungi.

Molecular characterization of tumors meeting diagnostic criteria for the non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP).

"Follicular variant" papillary thyroid carcinomas (FV-PTC) that do not histologically invade have a miniscule risk of metastasis, and thus been reclassified as a tumor of low malignant potential, the non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). There are few molecular studies of this tumor type. We performed gene expression analysis, by RNA sequencing, on a series of FV-PTCs, NIFTPs, and follicular adenomas.

Acute Invasive Fungal Rhinosinusitis: Frozen Section Histomorphology and Diagnosis with PAS Stain.

Acute invasive fungal rhinosinusitis (AIFRS) is a fulminant infection in immunocompromised patients requiring rapid diagnosis (DX), frequently made on frozen section (FS) of sinonasal biopsies, followed by prompt surgical debridement. However, FS interpretation is often difficult and DX sometimes not possible. In this study we sought to characterize reasons for misinterpretation and methods to improve diagnostic accuracy.

Evidence of a positive association between malpractice climate and thyroid cancer incidence in the United States.

The incidence of thyroid cancer has risen dramatically in the past few decades. The cause of this is unclear, but several lines of evidence indicate it is largely due to overdiagnosis, the diagnosis of tumors that would have never manifest clinically if untreated. Practices leading to overdiagnosis may relate to defensive medicine.

Frozen Section as a Rapid and Accurate Method for Diagnosing Acute Invasive Fungal Rhinosinusitis.

Objective Identify methods to improve the frozen-section diagnosis of acute invasive fungal rhinosinusitis. Study Design Biopsies with frozen section for suspected acute invasive fungal rhinosinusitis were reviewed to identify causes for missed diagnoses and evaluate methods for potential improvement. Setting All aspects of the study were performed at the Penn State Milton S.

Long-term recurrence-free survival after an unplanned reduction in radiotherapy for HPV-positive oropharyngeal SCC: Two cases and a review of the literature.

There is currently no clear distinction between the treatment of HPV-positive and HPV-negative oropharyngeal squamous cell carcinoma (OPSCC). HPV-positive OPSCC has been demonstrated to be more radiosensitive than its HPV-negative counterpart. Despite this, patients with HPV-positive OPSCC continue to receive a full dose of radiation (70 Gy) outside clinical trials.

Altered molecular profile in thyroid cancers from patients affected by the Three Mile Island nuclear accident.

Objectives/hypothesis: In 1979, Three Mile Island (TMI) nuclear power plant experienced a partial meltdown with release of radioactive material. The effects of the accident on thyroid cancer (TC) in the surrounding population remain unclear. Radiation-induced TCs have a lower incidence of single nucleotide oncogenic driver mutations and higher incidence of gene fusions.

Clinical comparison of noninvasive urine tests for ruling out recurrent urothelial carcinoma.

Objective: Patients with urothelial carcinoma (UC) undergo rigorous surveillance for recurrence. Noninvasive urine tests are not currently recommended by guideline panels owing to insufficient clinical benefit. The objective of this study was to prospectively compare the performance of the Cxbladder Monitor test to other commonly available urine markers and cytology for surveillance of patients with UC.

Subcutaneous nasal angioleiomyoma: Case of a rare tumor and review of the literature.

We describe the case of a 46-year-old woman with a rare presentation of angioleiomyoma of the subcutaneous nasal tissue. The patient presented with pain and severe nasal obstruction. Her nasal deformity was sufficient to indicate an external rhinoplasty for both extirpation of the tumor and reconstruction of the defect with cartilage grafts.

Clinically localized type 1 and 2 papillary renal cell carcinomas have similar survival outcomes following surgery.

Purpose: We aimed to determine incidence, pathologic findings, prognostic factors and clinical outcomes for patients with clinically localized papillary RCC.

Methods: Demographic, clinical and pathologic findings were collected on all patients with PRCC undergoing surgery at four academic medical centers. The primary endpoint was cancer-specific survival (CSS).

Frozen Section Interpretation of Pancreatic Margins: Subspecialized Gastrointestinal Pathologists Versus General Pathologists.

Intraoperative assessment of pancreatic parenchymal margin during pancreatectomies is challenging and misinterpretation by the pathologist is a cause of incorrect frozen section (FS) diagnosis. Although the current literature supports that pancreatic margin FS diagnosis and its accuracy has no impact on the patient outcome for pancreatic ductal adenocarcinoma (PDAC) patients and reexcision in an attempt to achieve a negative intraoperative pancreatic margin after positive FS is not associated with increased overall survival; still it remains a routine practice in many institutions. To this end, we sought to assess the interobserver variation and accuracy of FS diagnosis between subspecialized gastrointestinal/pancreatobiliary (GI) and general pathologists.

Unusual sites of metastasis of papillary thyroid cancer: Case series and review of the literature.

Papillary thyroid cancer (PTC) is the most common malignancy of the thyroid gland. It typically spreads via lymphatic extension. The rate of regional PTC metastasis to the neck is relatively high, while metastases outside the deep cervical chain are rare.

Loss of FOXA1 Drives Sexually Dimorphic Changes in Urothelial Differentiation and Is an Independent Predictor of Poor Prognosis in Bladder Cancer.

We previously found loss of forkhead box A1 (FOXA1) expression to be associated with aggressive urothelial carcinoma of the bladder, as well as increased tumor proliferation and invasion. These initial findings were substantiated by The Cancer Genome Atlas, which identified FOXA1 mutations in a subset of bladder cancers. However, the prognostic significance of FOXA1 inactivation and the effect of FOXA1 loss on urothelial differentiation remain unknown.

Multifocal inverted papillomas in the head and neck.

Inverted papilloma is a rare benign neoplasm that usually originates in the lateral nasal wall. It can be a locally aggressive lesion and invade nearby structures. While primarily a nasal neoplasm, cases of an inverted papilloma involving the temporal bone, pharynx, nasopharynx, and lacrimal sac have been reported.

A rare soft tissue tumor masquerading as a parathyroid adenoma in a patient with birt-hogg-dubé syndrome and multiple cervical endocrinopathies.

Birt-Hogg-Dubé (BHD) syndrome is an autosomal dominant disorder that presents with renal tumors, pulmonary cysts with spontaneous pneumothoraces, and skin hamartomas. We present a case of a 67-year-old female with multiple endocrinopathies and a history of BHD syndrome. In 2011, a thyroidectomy with a four-gland parathyroidectomy was performed for toxic multinodular goiter (TMNG) and parathyroid hyperplasia.

Do black (dark) lymph-node metastases in papillary thyroid carcinoma suggest more advanced or aggressive disease?

Background: In some patients, papillary thyroid carcinoma (PTC) lymph-node metastases are noted to be black (dark) in color at the time of surgical removal. The goal of this project was to determine histological, genetic, and clinical features that are associated with regional black PTC metastasis.

Methods: Fifteen patients with black PTC metastases (black-PTC) were compared to a control cohort of 15 patients with nonblack PTC metastasis (nonblack PTC).

Dedifferentiated epithelial-myoepithelial carcinoma: analysis of a rare entity based on a case report and literature review.

Dedifferentiated epithelial-myoepithelial carcinoma (DEMC) is very rare salivary gland neoplasm with only anecdotal reports. We present an analysis of DEMC, based on a case and review of literature. Our patient, an 85-year-old woman, presented with a submandibular mass of 5 years duration that was increasing in size over a 5-week period.

A comparative study of cell cycle mediator protein expression patterns in anaplastic and papillary thyroid carcinoma.

Anaplastic thyroid carcinoma (ATC) is an extremely aggressive and rapidly fatal neoplasm. The aim of this study was to identify a limited cell cycle associated protein expression pattern unique to ATC and to correlate that pattern with clinical outcome. This represents one of the largest tissue micro-array projects comparing the cell cycle protein expression data of ATC to other well-differentiated tumors in the literature.
