Esthesioneuroblastoma (ENB) is a rare malignancy arising from the olfactory epithelium of the nasal vault. ENB accounts for 3% to 6% of all intranasal tumors and has the best prognosis among sinonasal malignancies with neuroendocrine differentiation. The optimal treatment continues to be controversial, but the benefit of adjuvant therapy, particularly(More)
Adenocarcinomas occurring in the vagina are rare. Their correct classification may be very challenging to both the gynecologist and the pathologist, but it is essential for appropriate therapy. Although most adenocarcinomas in the vagina arise from other sites in the female genital tract, a significant minority reflects metastasis from a colorectal site. We(More)
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(More)
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. Histologically,(More)
BACKGROUND Although thyroid cancers are readily treatable with surgery and radioactive iodine, there are problems in managing recurring, as well as locally advanced, thyroid cancer. The opioid growth factor (OGF) and its receptor, OGF receptor (OGFr), form a tonically active, autocrine-paracrine loop that serves to inhibit cell proliferation in a wide(More)
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(More)
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(More)
