BACKGROUND: The differential diagnosis of facial anesthesia is vast. This may be secondary to trauma, neoplasm, both intracranial and extracranial, infection, and neurologic disease. When evaluating a patient with isolated facial anesthesia, the head and neck surgeon often thinks of adenoid cystic carcinoma, which has a propensity for perineural invasion and spread. When one thinks of head and neck squamous cell carcinoma with or without unknown primary, the typical presentation involves dysphagia, odynophagia, weight loss, hoarseness, or more commonly, a neck mass...

BACKGROUND: MicroRNAs (miRNAs or miRs) are post-transcriptional regulators of eukaryotic cells and knowledge of differences in miR levels may provide new approaches to diagnosis and therapy. METHODS: The present study measured the levels of nine miRs in head and neck squamous cell carcinomas (HNSCC) and determined whether clinical pathological features are associated with differences in miR levels. SET (I2PP2A) and PTEN protein levels were also measured, since their levels can be regulated by miR-199b and miR-21, respectively...

Cutaneous squamous cell carcinoma (SCC) is a malignancy that arises from epidermal keratinocytes. Although the majority of cutaneous SCC cases are easily treated without further complication, some behave more aggressively and carry a poor prognosis. These "high-risk" cutaneous SCCs commonly originate in the head and neck and have an increased tendency toward recurrence, local invasion, and distant metastasis. Factors for high-risk cutaneous SCC include large size (>2 cm), a deeply invasive lesion (>2 mm), incomplete excision, high-grade/desmoplastic lesions, perineural invasion (PNI), lymphovascular invasion, immunosuppression, and high-risk anatomic locations...

Adenoid cystic carcinoma is a rare neoplasm commonly originating from the minor salivary glands. The clinical findings typical of this tumor include slow growth, perineural invasion and high frequency of local recurrence. In this study, a patient presented with a tongue base lesion that was treated with surgical excision and additional postoperative external beam radiotherapy. However, local recurrence occurred 8 months after radiotherapy. If recurrence occurs after radiation therapy, total glossectomy should be considered...

Basal cell carcinomas are the most common malignant tumors of the eyelids. Patient history, clinical symptoms and signs, inspection, palpation and slit-lamp examination usually allow a working diagnosis; however, the clinical diagnosis requires histopathological confirmation and determination of the histopathological type. Squamous cell carcinomas, sebaceous gland carcinomas, melanomas and Merkel cell carcinomas can metastasize usually via the lymph vessels into the regional lymph nodes. Microscopically controlled excision of the primary tumor into healthy tissue is most commonly the first goal...

INTRODUCTION: Peripheral nerve sheath tumors (PNSTs) are an assorted group of neoplasms originating from neuroectoderm and growing in peripheral nerves. Malignant transformation leads to a poor prognosis and is often lethal. Current treatment of PNSTs is predominantly surgical, which is often incomplete or accompanied by significant loss of function, in conjunction with radiotherapy and/or chemotherapy, for which the benefits are inconclusive. Oncolytic viruses (OVs) efficiently kill tumor cells while remaining safe for normal tissues, and are a novel antitumor therapy for patients with PNSTs...

PURPOSE: Primary vulvar melanoma (PVM) is the second most common vulvar malignancy. Despite their distinct anatomic site and unique molecular-genetic alterations, PVMs are staged according to the American Joint Committee on Cancer (AJCC) guidelines for primary cutaneous melanomas (PCM). However, whether parameters derived for PCM also apply to PVM remains a critical yet largely unexplored clinical question. The objective of this study was to determine the parameters predictive of survival in PVM...

Penile carcinoma (PC) is more frequent in underdeveloped countries, generally is diagnosed at an advanced stage when therapeutic options are restricted, and thus is associated with high morbidity/mortality rates. Recent studies have demonstrated clinical benefits with epidermal growth factor receptor (EGFR)-targeted therapy in PC patients, although there is no test that provides accurate patient selection. The aim of the present study was to evaluate the prognostic value of EGFR gene and protein status in tumor samples from patients with primary penile squamous cell carcinoma (SCC)...

OBJECTIVE: To evaluate the association of biopsy perineural invasion (PNI) with adverse pathological findings on radical prostatectomy in patients who would have been candidates for active surveillance (AS). METHODS: Using a prospectively populated database of 3084 men who underwent open radical prostatectomy, candidates for AS by strict (Johns Hopkins) and expanded (University of Toronto) criteria were identified. The presence of adverse pathologic features at radical prostatectomy was compared between those men with and without biopsy PNI...

Perineural invasion (PNI) hinders the ability to establish local control of oral squamous cell carcinoma (OSCC). To date, PNI can be evaluated only in surgical specimens and not in preoperative biopsy material, rendering timely therapeutic planning impossible. Insulin-like growth factor-II mRNA binding protein-3 (IMP3) expression appears to be of diagnostic and prognostic utility for many solid tumours, and laminin-5 expression in surgical specimens has been identified as a valid predictor of neural spread of head-and-neck neoplasms...
