background: the impact of positive intramammary lymph node (im ln) on the prognosis of patients with breast cancer has been debated for years; likewise, the standard management of patients with positive im ln remains unclear, especially when it is identified by preoperative imaging or by sentinel lymph node biopsy. the present study aims at reviewing the level of concurrent involvement of im ln...

schwannomas are benign nerve sheath tumors that originate from any anatomical site. most of the schwannomas are found in the head, neck or limbs. schwannoma arising in a lymph node is extremely rare. we have found only four cases in the review of the literature. we experienced a case of intranodal schwannoma in a perigastric lymph node. a 72 year-old female underwent cholecystectomy due to clin...

discussion benign metastasizing pleomorphic adenoma is a rare and controversial but distinct clinical entity. although the definition of the term benign precludes metastatic disease, these tumors do not demonstrate any malignant features yet metastasized to distinct sites. it remains to be determined whether this benign metastasizing pleomorphic adenoma is really low grade salivary malignancy. ...

Metastatic recurrence of colon cancer in the left supraclavicular lymph node (Virchow lymph node) is rare, and to date there are no reports on radiotherapy as treatment. We report on a case of metastatic recurrence of sigmoid colon cancer in the Virchow lymph node with severe lymph node metastases successfully treated with a combined modality therapy of systemic chemotherapy and radiotherapy. T...

We report a 65-year-old male with histopathologically proven prostate cancer and multiple pelvic node metastases using a robotic-assisted radical prostatectomy procedure plus extended pelvic lymph node dissection. Positron emission tomography (PET) scan findings demonstrated a moderate accumulation of 11C-choline in a metastatic left obturator node sized 8 × 8 mm, though only a faint uptake of ...

OBJECTIVES To assess the performance of contrast-enhanced ultrasound (CEUS) intended to differentiate hyperplastic from malignant neck lymph nodes in an animal model. METHODS Twenty-four New Zealand rabbits were randomly divided into two groups: neck lymph node metastasis group (12 rabbits) and reactive hyperplastic lymph node group (12 rabbits). Tongue VX2 carcinoma with cervical lymph node ...

BACKGROUND Carcinoma ex pleomorphic adenoma (Ca ex PA) is a high-grade carcinoma arising from benign pleomorphic adenoma. This is the first population-level analysis of prognosis and prognostic features of parotid Ca ex PA. METHODS The Surveillance, Epidemiology, and End Results (SEER) database (1988-2009) was used to identify 278 patients with parotid Ca ex PA. RESULTS Extraparenchymal ext...
