BACKGROUND: Paranasal sinus lymphoma is a rare clinical entity. METHODS: We conducted a retrospective case series of 68 patients with biopsy-confirmed paranasal sinus lymphoma with attention on systemic disease association. RESULTS: Of 63 patients with paranasal sinus lymphoma, 35 (56%) had systemic involvement. Four patient groups were identified: (1) primary paranasal sinus lymphoma (44%); (2) systemic disease occurring concurrently with paranasal sinus lymphoma (25%); (3) paranasal sinus lymphoma with relapse of preexisting systemic lymphoma (22%); and (4) progression to systemic disease after primary paranasal sinus lymphoma (8%)...

Human papillomavirus (HPV) has changed the face of head and neck cancer over the past 2 decades. No longer is this solely a disease of older patients with a history of heavy tobacco and alcohol use. Patients with HPV-related head and neck cancers tend to be younger, healthier, and have an improved prognosis, compared with those with HPV-negative tumors. As more patients are diagnosed with HPV-related head and neck cancer, physicians have important topics to consider. These include prevalence, transmission, and natural history of HPV, the role of screening, vaccines, and HPV testing in head and neck cancer...

BACKGROUND: The lymphatic vasculature provides a route for cancer metastases, and its dysfunction after cancer treatment can result in lymphedema. However, changes in the lymphatics before, during, and after surgery and radiation remain unclear. METHODS: Near-infrared fluorescence lymphatic imaging was performed before and after lymph node dissection and fractionated radiotherapy to assess changes in external lymphatic function. RESULTS: Patients who underwent both lymph node dissection and radiotherapy developed lymphatic dermal backflow on treated sides ranging from days after the start of radiotherapy to weeks after its completion, whereas contralateral regions that were not associated with lymph node dissection but also treated with radiotherapy experienced no such changes in external lymphatic anatomies...

BACKGROUND: The potential benefits of (18) F-fluoro-2-deoxy-D-glucose-positron emission tomography/CT (FDG-PET/CT) imaging for radiotherapy (RT) treatment planning of head and neck squamous cell carcinoma (HNSCC) are increasingly being recognized. It has been suggested that intratumoral subvolumes with high FDG avidity ("hotspots") are potential targets for selected dose escalation. The purposes of this study were to demonstrate that pre-RT FDG-PET/CT can identify intratumoral sites at increased risk of local relapse after RT and to determine an optimal threshold to delineate smaller RT target volumes that would facilitate RT dose escalation without impaired tolerance...

BACKGROUND: Cervico-mediastinal hemangiomas in adulthood are rare and slow-growing vascular tumors. The optimal treatment for giant hemangiomas is controversial. In asymptomatic cases, clinical observation is generally recommended. METHODS: We report the transoral resection of a pharyngolaryngeal hemangioma (diameters of 44 × 56 × 39 mm) with tracheal involvement and mediastinal extension. Clinically, the patient had throat foreign body sensation, severe dyspnea and stridor...

BACKGROUND: Papillary thyroid cancer (PTC) occasionally presents with metastases to the lateral neck, without clinically evident disease in the central neck. These cases may ultimately manifest as either skip metastases to the lateral compartment or as occult metastases in the central compartment. METHODS: This is a retrospective review of 80 patients with PTC with metastases to the lateral cervical lymph nodes treated from 2006 to 2015. Photographs of the cadaveric dissections were used with permission from the author...
