PURPOSE To investigate the use of asymmetric collimators and a single isocenter for delivering a uniform, accurate dose of radiation to the head, neck, and supraclavicular lymph nodes. METHODS AND MATERIALS A linear accelerator with a pair of asymmetric collimators is required for this technique. An isocenter was placed at the junction of the lateral head and neck fields and the anterior supr...

INTRODUCTION Fever of unknown origin (FUO) is a common initial presentation leading to a diagnostic challenge. PATIENT CONCERNS A 3-month history of moderate-to-high fever was reported in an otherwise healthy 54-year-old man. Enhanced computed tomography (CT) scans of his chest showed a remarkable progressive enlargement of bilateral cervical, supraclavicular, hilar, and mediastinal lymph nod...

Introduction: The applicability of sentinel lymph node biopsy for early detection of metastasis in patients with renal cell carcinoma (RCC) is still in the validation phase and under investigation, which might be due to the unpredictability of the lymphatic pattern in RCC. In this study, we aimed to evaluate the feasibility and accuracy of sentinel node biopsy in patients with ...

OBJECTIVES The extension of non-small-cell lung cancer (NSCLC) to supraclavicular (SC) and contralateral (CL) mediastinal lymph nodes is termed N3 and usually forbids surgical resection. However, scarce surgical series have reported encouraging results, and we sought to analyse our experience with this particular subgroup of patients. METHODS We retrospectively reviewed the charts of 5857 pat...

Background. Myeloid sarcoma is an extramedullary neoplasm of immature myeloid cells. Our study reports a presentation of myeloid sarcoma which presented with severe leukemoid reaction as a secondary malignancy in a patient who was treated for acute lymphoblastic leukemia previously. The case emphasizes the difficulties in diagnosis of patients who do not have concomitant leukemia. Case Presenta...

OBJECTIVES The purpose of this study was to determine the most suitable candidates for scalene lymph node biopsy to detect non-palpable scalene lymph node metastasis (N(3)-scalene) in non-small cell lung cancer patients. METHODS Standard cervical mediastioscopies and ipsilateral scalene lymph node biopsies were performed preoperatively by a single surgeon on 121 consecutive patients with non-...

a 19-year-old girl referred to our clinic complaining of a painless lump on the left side of her tongue.  the patient had no history of dysphagia, lingual paresthesia or bleeding. physical examination revealed the presence of multiple enlarged lymph nodes on the left side of her neck.  histopathology of lingual mass and lymph nodes showed pleomorphic adenoma.  to our knowledge, this is the firs...
