introduction: breast cancer is the most common cancer and the second cause of death in women. it is essential to have the highest level of confidence in axillary staging assessment. many surgeons and pathologists believe that fewer lymph nodes are present in axillary dissection specimens of women treated by neoadjuvant chemotherapy. consequently, the purpose of this study was to compare the lym...

objectives: presence/absence of cervical lymph node metastasis plays a critical role in prognosis and survival of patients with oral squamous cell carcinoma (scc). this study was designed to assess the diagnostic accuracy of computed tomography (ct) scan for detection of cervical lymph node metastasis in oral scc in comparison with histopathological analysis after neck dissection methods: in th...

We report a young male with an initial excisional biopsy report of melanoma of the lower back, referred to our hospital for complete excision and sentinel lymph node (SLN) biopsy.  Four peritumoral intradermal Tc-99m phytate injection was performed and SLNs were detected in both axillary and right inguinal regions. On the biopsy only the right axillary SLN was metastatic leading to right axilla...

results of the 53 neck dissection specimens, histopathology showed metastases in 16 cases. the overall accuracy of usgfna, us and palpation was 96%, 68% and 70%, respectively. the specificity of usgfna was superior to palpation and us alone. usgfna had the highest sensitivity, predictive value and accuracy in detecting cervical metastases compared with other performed tests. conclusion in our s...

Background: Cervical cancer is the second most common type of cancer among women. Effective screening programs can help cancer detection in early phases and reduce death. Metastasis to lymph nodes is one of the most prognostic factors in patients who underwent surgery. Also, a positive result from pathology report alert oncologist as a cause of death. Sentinel lymph node biopsy has been widely ...

sarcoidosis is a systemic disease that is characterized with noncaseating granulomatous nodules which present in multiple organs specially lungs (90%) . incidence of masses due to sarcoidosis in upper extremity is low and most cases present in association with involvement of pulmonary hilary lymph nodes. in this article we present a rare case of sarcoidosis which presented as a single soft tiss...

background: this study attempts to ascertain a reliable cutoff size to determine whether pelvic lymph nodes are metastatic or not in ovarian cancer patients. methods: we retrospectively reviewed 73 pet/ct scans of 52 female patients with ovarian carcinoma who underwent surgery followed by chemotherapy. the findings of contrast enhanced mdct were interpreted by two experienced radiologists unawa...
