BACKGROUND: Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neuroendocrine tumor arising on the head and neck in 40%-50% of patients. Between 20% and 40% will harbor subclinical nodal metastasis. METHODS: Using search terms 'Merkel AND sentinel', MEDLINE, PUMED, and EMBASE databases were systematically reviewed for publications regarding sentinel lymph node biopsy (SLNB) in classification I and II MCC of the head and neck. RESULTS: Twenty-nine publications encompassing 136 patients were included...

INTRODUCTION: Ultrasonography is the easiest non-invasive method to diagnose lymph node metastases in patients with head and neck cancer. However, since CT scans are often preferred in the evaluation of primary tumours of these patients, information about lymphatic metastases may also available in these patients. Therefore, ultrasound is not routinely employed in the evaluation of these patients. However, elastography technique, a recent development in ultrasound technology, could make use of ultrasonography in these patients even more widespread, even though it is still not widely used today...

Optical molecular imaging, a highly sensitive and noninvasive technique which is simple to operate, inexpensive, and has the real-time capability, is increasingly being used in the diagnosis and treatment of carcinomas. The near-infrared fluorescence dye indocyanine green (ICG) is widely used in optical imaging for the dynamic detection of sentinel lymph nodes (SLNs) in real time improving the detection rate and accuracy. ICG has the advantages of low scattering in tissue absorbance, low auto-fluorescence, and high signal-to-background ratio...

Heterotopic Warthin's tumor (WT) arising from the cervical lymph nodes is uncommon and WT presenting concomitantly with classical Hodgkin's lymphoma has only been previously reported three times in English literature. The current study presents an unusual case of classical Hodgkin lymphoma (CHL) involving the heterotopic WT in a 59-year-old male. Histopathologic examination revealied a WT with extensive expansion of mixed-cellularity CHL in a lymph node in the right of the neck. Clinical staging was determined as stage IA disease...

Head and neck squamous cell carcinoma (HNSCC) is usually diagnosed accompanied by lymph node metastasis. C-C chemokine receptor type 7 (CCR7) is associated with the invasion and metastasis of tumors in HNSCC through various signaling pathways. The role of hsa-miR-125a-5p in HNSCC remains unclear. The present study was performed to investigate the association between hsa-miR-125a-5p and CCR7 in HNSCC. Reverse transcription-quantitative polymerase chain reaction was applied to analyze the expression of hsa-miR-125a-5p in clinical samples...

OBJECTIVE: To explore the value of micro surface coil combined with three-dimensional reversed fast imaging with steady-state precession and diffusion-weighted imaging (3D-PSIF-DWI) in displaying intraparotid facial nerves and parotid ducts. METHODS: In total 24 healthy volunteers with no parotid disease underwent scanning of head and neck coil and 4-cm micro surface coil combined with 3D-PSIF-DWI prospectively. The obtained original images were processed through maximum intensity projection, multiplanar reconstruction, and curved planar reconstruction...

Mutated or dysregulated DDX3 participates in the progression and metastasis of cancer via its multiple roles in regulating gene expression and cellular signaling. Here we show that the high expression levels of DDX3 in head and neck squamous cell carcinoma (HNSCC) correlate with lymph node metastasis and poor prognosis and demonstrate that DDX3 is essential for the proliferation, invasion, and metastasis of oral squamous cell carcinoma (OSCC) cells. Microarray analyses revealed that DDX3 is required for the expression of a set of pro-metastatic genes including ATF4-modulated genes in an aggressive OSCC cell line...

Objective: To determine the correlation between the expression of IL-33 and significance in cancer biologial and patient's prognosis in head and neck squamous cell carcinoma (HNSCC). Method: Twenty pairs of tumor tissue and adjacent normal tissue were collected. qRT-PCR and immunohistochemistry (IHC) were used to detect the expression of IL-33 mRNA and protein in tissues. Correlation between IL-33 expression with clinicopathologic features of 107 HNSCC patients were analyzed. Result: IL-33 mRNA and protein expression levels in normal tissue were higher than paired tumor tissue...

The clinical manifestations were pharyngalgia anddysphagia. Physical examination found that the size of a mobilizable and hard lymph node in the area of the right neck Ⅱ was about 2.0 cm×2.0 cm. Ultrasound examination demonstrated abnormal lymphadenopathy in bilateral neck which was considered metastatic cancer. Neck CT showed occupation of the hypopharynx, thickening bilateral aryepiglottic folds and false vocal cords, and enlargement lymph node in the bilateral neck Ⅱ area. Upper gastrointestinal radiography: The mucosa from the lower border of right pear-shaped fossa to the entrance of the esophagus was disrupted, and the partial lumen was narrowed...

INTRODUCTION: We report the first case of squamous cell carcinoma (SCC) of the thyroid gland coexisting with papillary thyroid carcinoma (PTC) and Hashimoto's thyroiditis and discuss various theories concerning the histogenesis of SCC of the thyroid gland and the optimal treatment strategy. CASE REPORT: A 54-year-old woman presented with an anterior neck mass measuring 4cm on clinical examination. Imaging showed a suspicious thyroid nodule invading the trachea. Total thyroidectomy with bilateral central lymph node resection was performed...

BACKGROUND: Sebaceous carcinoma is an aggressive adnexal skin tumor with a predilection for the eyelids and sebaceous glands of the head and neck. CASE PRESENTATION: A 73 year-old man presented with confusion and was found to have widely disseminated sebaceous carcinoma with metastases to brain, lungs, liver, bowel, lymph nodes, and bone. Following initial treatment of the brain metastases with surgery he received post-operative radiosurgery. He then began systemic immunotherapy with pembrolizumab...

OBJECTIVES: In 2010, a new subtype of salivary gland cancer (SGC), (mammary analogue) secretory carcinoma (SC), was defined, characterized by the ETV6-NTRK3 fusion gene. As clinical behavior and outcome data of this histological subtype tumor are still sparse, we aimed to describe the clinicopathological course and outcome of a series of translocation positive SC patients. PATIENT AND METHODS: We re-evaluated the pathological diagnosis of a subset of SGCs, diagnosed in 4 of 8 Dutch head and neck centers...

PURPOSE: The purpose of this clinical study was to evaluate the sensitivity and specificity of cervical sentinel lymph node biopsy after mapping with indocyanine green fluorescence (ICG) for imaging early-stage oral cancer. PATIENTS AND METHODS: A sentinel lymph node biopsy (SLNB) was performed during a selective neck dissection (SND) in 20 patients with oral squamous cell carcinoma (OSCC, cT1 or cT2, N0 status). The sentinel lymph nodes (SLN) were identified using an infrared video camera after ICG injection...
