BACKGROUND AND PURPOSE Although CT findings of Kikuchi disease (KD), or histiocytic necrotizing lymphadenitis, are reported in several case reports, large-scale analysis of the disease has not been undertaken. We characterized the clinical and CT findings in a large group of patients with KD. METHODS Between 1990 and 2002, 96 patients (68 women, 28 men; mean age, 24.4 years) underwent biopsy ...

Mucosal tolerance is a naturally occurring immunological phenomenon that prevents harmful inflammatory responses to ingested or inhaled environmental, predominantly nondangerous, Ags. The nasal mucosa is an extremely efficient compartment in the induction of immunological tolerance which can be exploited in Ag-specific treatment of autoimmune disease. With the use of a model Ag (OVA) and an Ag ...

BACKGROUND AND PURPOSE The hypervascular nature of parathyroid adenomas can be explored by proper dynamic imaging to narrow the target lesions for surgical exploration. The purpose of this study was to establish MR perfusion characteristics of parathyroid adenomas to differentiate them from their mimics, such as subjacent thyroid tissue and cervical lymph nodes. MATERIALS AND METHODS Preopera...

BACKGROUND Whether sonography is an appropriate imaging modality for cervical lymph nodes in patients with papillary thyroid microcarcinoma (PTMC) remains unclear. Hence, this study aimed to evaluate the diagnostic value of ultrasonography (US) features for lymph node metastasis in PTMC. METHODS Seven hundred twelve patients with PTMC who underwent conventional ultrasonography examinations of...

Malignant melanoma in children is rare. It can arise from congenital melanocytic nevi. In pediatric patients, diagnosis of melanoma is difficult and challenging because the physicians have a low index of suspicion. Marrow metastasis in malignant melanoma especially in children is extremely uncommon. Here, the authors reported a 5 year old girl who was presented with a 4 month history of pelvic ...

871 mesenteric lymph nodes taken from 110 native cattle from urmia slaughter-house with differentages were examined for linguatula serrata infection. the lymph nodes were studied based on their colourand consistency. 44% of the cattle were found positive for l. serrata infection. the number of parasitesisolated from each infected lymph node varied from 1 to 69 with a mean of 5.48. there were no...

The study included 26 patients with FIGO stage Ia1–Ib1 cervical cancer who underwent fertility-sparing surgery (transabdominaltrachelectomy). To visualize sentinel lymph nodes, lymphoscintigraphy with injection of 99mTclabelled nanocolloid was performed the day before surgery. Intraoperative identification of sentinel lymph nodes using hand-held gamma probe was carried out to determine the radi...
