High-grade neuroendocrine carcinomas (HGNECs) of the head and neck have the morphological appearance of undifferentiated carcinomas and could be histologically similar to human papillomavirus (HPV)-associated non-keratinizing squamous cell carcinomas of the head and neck. The aim of the study is to characterize histologically, immunohistochemically, and virologically these unusual neoplasms. Nineteen HGNECs of the head and neck (1 oropharyngeal, 5 sinonasal, 7 of the larynx, and 6 of the parotid gland) were reviewed and analyzed with a immunohistochemical panel, with special emphasis on cell cycle proteins...

In many regions of the world, the most common type of parotid malignancy is metastatic malignancy. Metastatic cutaneous squamous cell carcinoma and metastatic melanoma are the most common pathologies that metastasize to the parotid gland and cervical lymph nodes. Other more rare metastatic malignancies from cutaneous primary sites include Merkel cell carcinoma, pleomorphic sarcoma (previously called malignant fibrous histiocytoma) and metastatic basal cell carcinoma. Systemic metastases can also occur from tumors such as renal cell carcinoma...

INTRODUCTION: Up to the half of twentieth century, Chievitz organ was considered an embryonal organ, disappearing with growth. But Zenker, in 1953, demonstrated the existence of this organ in adult life, too4. REVIEW: In this article we review the embryology, the macroscopic and microscopic anatomy, the ultrastructure, the functional significance and the pathology of the Chievitz'Juxtaparotid Organ (CJO). The CJO is not a macroscopic apparent organ, but it looks like a nerve...

Cutaneous head and neck tumors mainly comprise malignant melanoma, squamous cell carcinoma, trichoblastic carcinoma, Merkel cell carcinoma, adnexal carcinoma, dermatofibrosarcoma protuberans, sclerodermiform basalioma and angiosarcoma. Adapted management requires an experienced team with good knowledge of the various parameters relating to health status, histology, location and extension: risk factors for aggression, extension assessment, resection margin requirements, indications for specific procedures, such as lateral temporal bone resection, orbital exenteration, resection of the calvarium and meningeal envelopes, neck dissection and muscle resection...

UNLABELLED: HASH(0x4de6a78) INTRODUCTION: Primary involvement of the salivary glands in small cell carcinoma is rare, and has one of the worst prognoses of salivary gland neoplasms. However, it has been reported that some cases have a favorable outcome, although the prognostic factors are still under consideration. Multidisciplinary therapy was usually required to achieve long-term survival. Recently, a resemblance of some small cell carcinomas of the salivary gland to cutaneous Merkel cell carcinoma was suggested; the latter have the potential for spontaneous regression, which is related to a favorable clinical outcome...

The aim of this study was to perform a systematic literature review of Merkel cell carcinomas (MCCs) originating exclusively in the ear, nose and throat (ENT) district. An appropriate string was run on PubMed to retrieve articles dealing with ENT presentations of MCC. A double cross-check was performed on citations and full-text articles found using the selected inclusion and exclusion criteria. In total, 43 articles were finally included in the study, describing 51 cases of MCC involving the ENT region: 22/51 (43%) cases involving the ear; 20/51 (39%) cases involving the mucosal sites; 9/51 (18%) cases involving other ENT regions...

BACKGROUND: Locally advanced head and neck cancer often requires wide resections of the cheek and parotid gland, and in an ageing population preferred reconstructive options aim to avoid lengthy operating times or high risk surgery. While most large parotid defects traditionally require free flap reconstruction, we describe a new and versatile locoregional flap that has been shown to be reliable, simple and safe. METHODS: We describe the cervico-submental (CSM) keystone-design perforator island flap for head and neck reconstruction, including an analysis of 33 consecutive patients with a range of head and neck defects...

Merkel cell carcinoma is a neuroendocrine tumor, with characteristic morphological and immunohistochemical features. Originally reported as primary carcinoma of skin, it has been described in numerous other sites such as lymph nodes, oral cavity, breast, vaginal walls, and salivary glands. Recent studies have revealed in cutaneous Merkel cell carcinomas a clonally integrated polyomavirus, named Merkel cell polyomavirus. The aim of the present study was to verify the presence of Merkel cell polyomavirus in 5 cases of primary Merkel cell carcinomas of lymph nodes and 1 case of parotid gland to investigate similarities or differences among Merkel cell carcinomas from various sites...

High-grade neuroendocrine carcinoma of the salivary glands is a rare malignancy that can be difficult to distinguish from metastatic neuroendocrine (Merkel cell) carcinoma of the skin, which often occurs on the head and neck and may metastasize to lymph nodes in or adjacent to salivary glands, particularly the parotid gland. As the 2 tumors have morphologic and immunophenotypic overlap, additional diagnostic tools may be clinically useful. Merkel cell carcinoma is known to harbor Merkel cell polyomavirus in up to 80% of cases...

Primary Merkel cell carcinoma (MCC) is a neuroendocrine tumor that typically affects older whites. It usually originates in the dermis, but in rare instances it has arisen in other primary sites, including the oral mucosa and the parotid gland. Explanations for the presence of MCC in these atypical locations have included theories of malignant transformation and neuroendocrine migration. We describe the case of a 35-year-old white woman who had an MCC in the parotid gland and no evidence of any other primary cutaneous lesion...

Merkel cell carcinoma is a rare malignant primary tumor of the skin, which develop typically in the elderly in the sun exposed areas of the skin, most commonly in the head and neck region. This tumor is very aggressive with a high rate of regional and distant metastases, marked propensity for local et regional recurrence, and very poor survival. Skin lesions are typically red or purple and present as a solitary dome-shaped nodule or indurated plaque. The recognition of such tumor in not difficult, but in same cases, when the tumor infiltrate deeper organs and structures it may cause some problems...

This paper presents the case of a 76-year-old woman who experienced a total regression of a Merkel cell carcinoma (MCC). The primary site of the tumor was on her right eyebrow. After this lesion was excised, the patient presented a massive locoregional metastasis on the right parotid gland and the laterocervical lymph nodes. No distant metastases were detected. An incisional biopsy into the right parotid gland confirmed the diagnosis of MCC metastasis. No surgical treatment was prescribed because of the advanced stage of the disease...

Merkel cells carcinoma (MCC) is an uncommon skin lesion, considered a malignancy of the neuroendocrine system, which is found mainly in elderly people. Its incidence is highly correlated with sun exposure or immunodeficiency syndromes. MCC is often an aggressive tumour with high tendency for local recurrence, lymph node involvement and distant metastasis. To our best knowledge 20 cases originated from the auricle have been described, 2 of them arising from external ear canal. The authors report a case of the ear canal characterized by two others synchronous tumours and the occurrence of a malignant high grade lymphoma, in which contribute of the pathologist was essential for a critical review...
