OBJECTIVES We describe a rare cause of posterior triangle cervical lymphadenopathy in a third decade female, outline the clinical and histopathological features and discuss excision biopsy as the investigation of choice in this age group, with lymphoma as the diagnosis of exclusion. CASE REPORT A thirty-four year old female was referred to our Head and Neck clinic with a one-month history of ...

BACKGROUND Kikuchi Fujimoto disease is an uncommon benign condition of necrotizing histiocytic lymphadenitis commonly seen in East Asian and Japanese populations. It commonly presents with fever, cervical lymphadenopathy, and elevated inflammatory markers. Diagnosis of Kikuchi Fujimoto disease is based on histopathological studies of the involved lymph nodes. The presentation of Kikuchi Fujimot...

A 66-year-old man, seen in 1971 after a presyncopal episode, was found to have a heart rate of 32 beats per minute. His ECG showed complete heart block with narrow QRS complexes. After two Adams-Stokes attacks in hospital a temporary pacemaker was inserted. He had previously been well with no history of tuberculosis nor of contact with tuberculosis. Investigation showed no evidence of myocardia...

The tumor necrosis factor (TNF) receptor family includes several important markers of activation in T cells. We examined expression patterns of two T-cell-associated members of these receptors, namely CD30 and OX40/CD134, in 148 cases of T-cell lymphoma to identify possible objective immunohistochemical criteria for subclassification of these tumors. CD30 expression was characteristic of tumors...

Genetic instability is a characteristic feature of the malignant Hodgkin and Reed-Sternberg (HRS) cells in classical Hodgkin's lymphoma and the lymphocytic and histiocytic (L&H) cells in lymphocyte predominant Hodgkin's lymphoma. Genetic instability can be classified into four major categories: distinct DNA mutations (microsatellite instability); numerical aberrations (chromosomal instability);...

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) differs in histological and clinical presentation from classical Hodgkin lymphoma (cHL). The typical morphologic signs of NLPHL are atypical "lymphocytic and histiocytic" (L&H) cells, which are surrounded by a non-neoplastic nodular background of small lymphocytes of B-cell origin. The NLPHL cells are positive for CD45, CD19, CD20, CD22 an...

Recent data suggest that tumor cells contaminating reinfused bone marrow may contribute to relapse in patients undergoing autologous bone marrow transplantation. Purging strategies that are able to remove these contaminating tumor cells need to be developed. This study describes how electroporation (EP) can be used to improve intracellular delivery of synthetic antisense oligodeoxynucleotides (...
