Merkel cell carcinoma (MCC) is a rare primary cutaneous neuroendocrine tumor that typically occurs on the head and neck of the elderly and follows an aggressive clinical course. Merkel cell polyomavirus (MCPyV) has been identified in up to 80% of cases and has been shown to participate in MCC tumorigenesis. Complete spontaneous regression of MCC has been rarely reported in the literature. We describe a case of a 79-year-old man that presented with a rapidly growing, 3-cm mass on the left jaw. An incisional biopsy revealed MCC...

The recent success of immunotherapies has demonstrated the potency of tumor-specific immune cells in mediating tumor rejection and generating durable tumor immunity. Our understanding of the scientific basis of these responses results from the confluence of a better comprehension of the cancer immunoediting process and the revolution in next generation sequencing of cancer genomes. Recent evidence suggests that T cell specificity for cancer cell expressed mutant proteins - termed neoantigens - is an important component of immune mediated tumor rejection...

Most parotid tumors grow slowly, and sometimes these patients do not request surgical treatment until the tumors become large and affect their appearance. The surgical treatment of these large tumors is usually accompanied by large skin defects after excision, and it is challenging for surgeons to close the defect primarily. This report describes the case of a 68-year-old man with a left parotid gland tumor (largest dimension, 110 mm) and the case of a 79-year-old man with a left parotid gland tumor measuring approximately 77 mm that had existed for decades...

Background To balance the risk of disease progression, morbidity and efficacy of reoperative central neck dissection (RCND) in papillary thyroid carcinoma, the latest clinical guidelines recommend early surgery over surveillance when the largest diseased node is >8 mm in its smallest dimension. However, the evidence remains scarce. To determine an appropriate size for first-time RCND, we examined the relationship between size of largest diseased central node, morbidity and response-to-therapy following RCND...

BACKGROUND: The 2015 American Thyroid Association (ATA) management guidelines for adult patients with differentiated thyroid cancer (DTC) propose the use of the modified initial risk stratification and response to therapy re-stratification systems. This study was conducted to validate the practicality of the revised guidelines for predicting tumor recurrence in patients with DTC. METHODS: Patients with papillary thyroid cancer (n=2425) who underwent total thyroidectomy with central neck node dissection with or without modified radical neck node dissection at a single institution between October 1985 and July 2009 were retrospectively enrolled...

BACKGROUND: In the 2015 American Thyroid Association guidelines, either lobectomy or total thyroidectomy was recommended for thyroid cancer < 4 cm without extrathyroidal extension (ETE) and lymph node (LN) metastasis. Therefore, the purpose of this study was to investigate factors predictive of bilaterality in papillary thyroid carcinoma (PTC) patients with tumor size < 4 cm. METHODS: We retrospectively reviewed 3296 conventional PTC patients who underwent total thyroidectomy with central neck dissection and/or lateral neck dissection between January 2008 and June 2015...

Sentinel lymph node biopsy is a crucial part of staging intermediate and thick melanoma. Lymphatic drainage from a tumor site can be highly variable, especially on the head, neck, and trunk. SPECT/CT fuses nuclear medicine and x-ray CT images to produce images with high anatomic detail. At our institution, SPECT/CT is performed routinely in addition to planar imaging. This article presents examples where SPECT/CT has proven helpful in image interpretation.

Melanoma is an important public health problem, and its incidence is increasing worldwide. The disease status of regional lymph nodes is the most important prognostic factor in early-stage melanoma patients. Sentinel lymph node biopsy (SLNB) was introduced in the early 1990s as a less invasive procedure than complete lymph node dissection to allow histopathologic evaluation of the "sentinel lymph node" (SLN), which is the first node along the lymphatic pathway from a primary tumor. Sentinel lymph node biopsy has minimal complication risks compared with standard complete lymph node dissection...

Among all cancers, the incidence of nasopharyngeal carcinoma (NPC) is quite high in the endemic regions. NPC is a head and neck cancer with poor survival rate, and is rare throughout most of the world but common in certain geographic areas, like southern Asia and some regions of North East India (Nagaland, Manipur, and Mizoram). A clear understanding of its etiology is still lacking, but NPC is widely suspected to be the result of both genetic susceptibility and exposure to environmental factors or Epstein-Barr virus infection...

Autophagy has been linked with melanoma risk and survival, but no polymorphisms in autophagy-related (ATG) genes have been investigated in relation to melanoma progression. We examined five single-nucleotide polymorphisms (SNPs) in three ATG genes (ATG5; ATG10; and ATG16L) with known or suspected impact on autophagic flux in an international population-based case-control study of melanoma. DNA from 911 melanoma patients was genotyped. An association was identified between (GG) (rs2241880) and earlier stage at diagnosis (OR 0...

Soft tissue myoepithelial neoplasms are a rare yet diverse group of tumors, ranging from benign to malignant lesions. Their presentation in the head and neck region is uncommon and represents a challenging diagnosis. Early identification of myoepithelial carcinoma is crucial given its more aggressive course compared to its benign counterpart, although the histopathological distinction between the two can be difficult. EWSR1 gene rearrangement is found in half the cases and has a speculative role in pathogenesis...

Introduction High mobility group box 1 is a versatile protein involved in gene transcription, extracellular signaling, and response to inflammation. Extracellularly, high mobility group box 1 binds to several receptors, notably the receptor for advanced glycation end-products. Expression of high mobility group box 1 and the receptor for advanced glycation end-products has been described in many cancers. Objectives To systematically review the available literature using PubMed and Web of Science to evaluate the clinical value of high mobility group box 1 and the receptor for advanced glycation end-products in head and neck squamous cell carcinomas...

Thyroid tumors affect all age groups, including children and adolescents. Malignant cancer of the thyroid is a relatively uncommon disease in pediatric age. In the recent decades the incidence of paediatric differentiated thyroid carcinoma (DTC) has increased. DTC in paediatric age is rare and has an excellent prognosis. Compared to adult counterpart, DTC in childhood presents some different features as follows: larger volume at the diagnosis, more frequent multicentricity (both mono- and bilateral), earlier local involvement of soft tissue of the neck, earlier lymph node involvement, distant metastases 3-4 times more frequent (most often in the lungs and almost always functional) and more common post-operatory recurrence; nevertheless, the prognosis of DTC in childhood is better and the survival greater than in adult...

Parathyroid carcinoma is a rare malignancy, which usually occurs as a sporadic disease, and less frequently in the setting of genetic syndromes. Despite the association of parathyroid and thyroid disorders being quite common, the coexistence of parathyroid carcinoma and thyroid disease is rare. We reviewed the pertinent literature. The terms "parathyroid carcinoma" and "thyroid disease, hyperthyroidism, thyrotoxicosis, hypothyroidism, thyroid nodule(s), Graves' disease, autonomously functioning thyroid nodules" were used both separately and in reciprocal conjunction to search MEDLINE for articles published from January 2007 to March 2016...
