However, hypopharynx had been not A 68-year-old woman came to outpatient clinic with a foreign body sensation her throat. round, smooth margin, bright pink-colored mass was confirmed by laryngoscopy. The patient took neck computer tomography. small bulging mucosa observed, but there no pe...

BACKGROUND Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumor. The majority of MECs occur in major or intraoral minor salivary glands. Herein, we present a case of MEC metastatic to cervical lymph nodes with an unknown primary site and discuss diagnostic and treatment options. METHODS AND RESULTS The patient was a 43-year-old man who presented with a large right-...

BACKGROUND Malignant parotid tumors are rare metastases originating from nasopharyngeal carcinoma (NPC). This study aimed to investigate the clinicopathological features and outcome of patients with metastasis of NPC to parotid lymph nodes after surgical therapy. METHODS We enrolled 14 NPC patients who had metastatic disease to parotid lymph nodes after IMRT. They received surgical treatment ...

OBJECTIVE By performing sentinel lymph node (SLN) biopsy, its detecting and predictive value to the cervical metastasis in the head and neck cancer patients was studied. METHODS Intraoperative SLN biopsy was done in 51 untreated head and neck cancer patients who all had no metastasis before operation. The lesions were: laryngeal cancer 23, pharyngeal cancer 6, thyroid cancer 20 and cancer of ...

Clinically apparent cervical lymphadenopathy has been found at the initial presentation in 23 to 56 % of cases of papillary thyroid carcinoma. Here we report tuberculous lymphadenitis mimicking metastatic lymph nodes from papillary thyroid carcinoma and suggest that tuberculosis apart from metastasis in papillary thyroid carcinoma should also be considered in the etiology of enlarged lymph node...

Forty-six patients with malignant melanoma metastatic to cervical or parotid lymph nodes with an unknown primary site were treated at UCLA Medical Center from 1964 through 1991. Treatment consisted of parotidectomy and/or neck dissection with or without adjuvant therapy. The initial presentation was a cervical mass in 74% and a parotid mass in 26% of patients. Metastasis distal to the head and ...

OBJECTIVES/HYPOTHESIS The incidence of occult perifacial nodal disease in oral cavity squamous cell carcinoma is not well reported. The purpose of this study was to evaluate the incidence of isolated perifacial lymph node metastasis in patients with oral squamous cell carcinoma with a clinically node-negative neck. The study will shed light on current controversies and will provide valuable cli...

BACKGROUND Cervical lymphadenopathy could be seen in several pathologic processes. An accurate differentiation between these conditions is of utmost importance to select an appropriate therapy and assess the prognosis. Gray scale and Doppler are appropriate sonographic techniques for evaluating internal and external features of lymph nodes. Although, various criteria have been proposed to diffe...

BACKGROUND Recurrences in the neck after neck dissections occur even in previously operated fields. Although the pathogenesis is unclear, it is well established that recurrences commonly occur at the jugular chain of nodes close to the carotid artery. We investigated the carotid sheath as possibly responsible for such regional recurrences. METHODS Patients undergoing therapeutic or elective n...

BACKGROUND During the pathologic examination of neck dissections, unexpected pathologic findings may occasionally be encountered. These pathologic findings may simulate malignant disease and/or have implications on the already complicated management of patients with head and neck cancer. METHODS We retrospectively reviewed 202 consecutive patients with a preoperative diagnosis of squamous cel...
