sentinel lymph node is the first regional lymph node that drains the lymph from the primary tumor. it is potentially the first nodeto receive the seeding of lymph‑borne metastatic cells. this study aimed to discuss lymphoscintigraphy procedural guidelines fordetection of sentinel node using tc‑phytate in isfahan, iran. moreover, the preliminary results of the first year’s clinical experience of...

CONTEXT AND OBJECTIVE Castleman's disease, or giant lymph node hyperplasia, is a rare disorder of the lymphoid tissue that causes lymph node enlargement. It is considered benign in its localized form, but aggressive in the multicentric type. The definitive diagnosis is based on postoperative pathological findings. The aim here was to describe a case of retroperitoneal unicentric Castleman's dis...

the diagnostic role of endobronchial ultrasoundguided transbronchial needle aspiration (EBUSTBNA) compared to conventional TBNA (cTBNA) in stage I and stage II sarcoidosis (1). The authors describe the yield of EBUS-TBNA to be significantly higher than cTBNA overall but was similar in the patients with lymph node station (4R and 7: group A) while it was higher in other lymph node stations (grou...

Systemic lymph node metastasis is a rare event in malignant mesothelioma. It is even more exceptional when systemic lymph node metastasis is the initial clinical presentation. Review of literature discloses only four cases in which metastatic lymphadenopathy was the only symptom of malignant mesothelioma. We, herewith, report three cases where the initial diagnosis of malignant mesothelioma was...

In experiments on rats by injection into the lungs of flint fractions of different sizes, ranging from under 0 5 to 8 microns (King, Mohanty, Harrison, and Nagelschmidt, 1953), it was observed that the hilar lymph nodes were enlarged after a certain time and that the different size classes of flint seemed to cause uneven development of these nodes. The effect was, therefore, studied in more det...

BACKGROUND The purpose of the study was to determine whether inclusion of computerized tomography (CT) in the prospective evaluation of vulvar cancer changed the surgical treatment strategy in terms of detection of lymph node metastases, tumor spread and comorbidity, and additionally to examine the logistical influence of adding further examinations prior to treating out-hospital patients refer...

A 54-year-old woman was treated for bronchial asthma for 14 yr. In March of 1989, chest roentgenography and computed tomography (CT) revealed development of bilateral pulmonary hilar lymph node enlargement. Positive 67Ga uptake was observed in bilateral pulmonary hili. Although levels of serum angiotensin converting enzyme (ACE) and lysozyme were within normal range, biopsy specimen of scalene ...

T susceptibility to malignancy of an undescended testis is well established. We report a 56-year old patient with giant intraabdominal seminoma of right undescended testis with no lymph node or distant metastasis, and normal left testis. The tumor was completely excised. The late presentation and size of the tumor were discussed. The patient is now 40 months postoperatively with no evidence of ...

Interdigitating dendritic cell sarcoma (IDCS), is an extremely rare neoplasm. We report a case of a 77-year-old man presented with gradual lymph nodes enlargement in inguina, neck and axilla for 6 months. Biopsy revealed that part of the lymph node was replaced by several large granuloma-like nodules composed of mild atypical tumor cells, resembling epithelioid cells. Mitotic figures were hardl...
