IMPORTANCE: Mucinous eccrine carcinoma is a rare entity that most commonly affects the head and neck. Due to its low frequency of occurrence, review of its etiology, histopathology, and treatment strategies is beneficial to all clinicians who may encounter similar appearing masses. OBSERVATION: An 84-year-old male presented with a blue mass on the left cheek. This mass started as a small bump and grew significantly over one year. His primary care physician monitored its growth and ultimately referred to an otolaryngologist...

E Rashidghamat, E Calonje
Radiation induced sarcoma is an unusual but well documented tumor. The frequency of radiation induced sarcoma of the head and neck region has been reported as 0.143%. In the literature the median interval between irradiation and development of sarcoma is 11 years. Cases of RIS with a short latent period i.e. less than four years are rare. We report a case of a 34 year-old female who developed an osteosarcoma of the scalp, over a previous craniotomy scar, three years after excision of a frontal anaplastic oligodendroglioma which had been followed by a course of 6 weeks radiotherapy (58 Gy) and 6 cycles of Temozolomide...

BACKGROUND: Planar lymphoscintigraphy (PL) has a lower detection rate of sentinel lymph nodes (SLNs) in head and neck melanoma compared with other sites. We assessed situations when single-photon emission computed tomography/computed tomography (SPECT/CT) identified nodes not seen by PL. We also evaluated the impact of SPECT/CT on surgical approach and oncologic outcomes. METHODS: Patients who underwent SLN biopsy (SLNB) for head and neck melanoma with PL and SPECT/CT between November 2011 and December 2016 were included...

Head and neck cancer is characterized by malignant tumors arising from the epithelium covering the upper aerodigestive tract, and the majority of these epithelial malignancies are squamous cell carcinomas (SCCs) of the oral cavity (OSCCs). The aim of the current work was to identify miRNAs regulated in OSCC cancerous tissue when compared to a healthy adjacent tissue and to verify the presence of the same miRNAs in the circulation of these patients. For that serum samples and biopsies of healthy and tumor tissues were collected from five patients diagnosed with OSCC of the oral cavity, RNA was extracted from these samples and microRNAs libraries were prepared and sequenced...

OBJECTIVES: Immediately or after head-and-neck (H&N) cancer chemoradiotherapy (CRT), patients may undergone significant sensorineural hearing loss (SNHL) which could affect their quality of life. Radiomic feature analysis is proposed to predict SNHL induced by CRT. MATERIAL AND METHODS: 490 image features of 94 cochlea from 47 patients treated with three dimensional conformal RT (3DCRT) for different H&N cancers were extracted from CT images. Different machine learning (ML) algorithms and also least absolute shrinkage and selection operator (LASSO) penalized logistic regression were implemented on radiomic features for feature selection, classification and prediction...

Alpha smooth muscle actin (SMA) belongs to the actin proteins. It is a known immunohistochemical marker for tumors of mesenchymal origin. There have been reports of expression of SMA in certain epithelial malignancies in the head and neck and genital regions. In this study, the authors report a primary cutaneous spindle cell squamous carcinoma expressing SMA. Both high- and low-molecular-weight keratins and p63 were positive, and S100 protein, SOX10, MART-1/Melan-A, and muscle-specific actin stains were negative...

PURPOSE OF REVIEW: To present the current state of knowledge concerning the role of conservative surgery in the treatment of synovial sarcomas of the upper aero-digestive tract (UADT). RECENT FINDINGS: The wider experience on synovial sarcomas involving the extremities and the results of retrospective reports focused on head and neck synovial sarcomas tend to justify a conservative surgical approach when dealing with tumors involving the UADT. SUMMARY: UADT synovial sarcomas is an extremely rare clinical entity (only around 50 cases reported in the literature, with four more herein presented from our own surgical series), with no clear guidelines concerning its treatment...

Upregulation of programmed death 1 ligand 1 (PD-L1) in cancer cells and its ligation to PD-1 on T cells facilitates cancer cell escape from immune surveillance. Therapies with PD-1 or PD-L1 antibodies have resulted in marked clinical responses in various cancer types. Hence, modulators that inhibit PD-L1 expression in cancer cells may serve as a novel strategy by which to enhance host immune responses. In the present study, we investigated the effects of miR-375 on PD-L1 expression in head and neck squamous cell carcinoma (HNSCC) cells by qRT-PCR and western blot analyses...

Head and neck squamous cell carcinoma (HNSCC) poses a significant challenge clinically where one of the mechanisms responsible for the invasion into facial bones occurs via the activation of osteoclasts. Copper has been demonstrated to play a key role in skeletal remodeling. However, the role of copper in cancer-associated bone destruction is thus far unknown. Lysyl oxidase (LOX) is a copper-dependent enzyme that promotes osteoclastogenesis. In the present study, we investigated the effects of copper on HNSCC with bone invasion by the copper chelator, ammonium tetrathiomolybdate (TM) in vitro and in vivo...

Tuberculosis (TB) of the head and neck region is quite common in endemic countries, but is still misdiagnosed due to its varied presentation and different sites of involvement. The aims of the present study were to present the diversities of presentation of head and neck tuberculosis with the diagnostic predicaments faced during evaluation and to assess treatment response to anti-tubercular treatment (ATT). We analysed 48 patients with head and neck tuberculosis who presented to the Department of Otorhinolaryngology in our tertiary care urban hospital over a period of two years from 2013 to 2015 and recorded their data, which included presenting complaints, local and systemic examination findings, investigation results and treatment outcomes...
