Castleman disease is a non-malignant proliferative disease of the lymphoid system. It can be unicentric or multicentric. In this report, we present a case of multicentric Castleman disease to which coronary artery pseudoaneurysm, vena cava superior occlusion, and antiphospholipid antibody positivity was accompanying.

to the editor: The case of human herpesvirus 8 (HHV-8) reported by Dagna et al. (July 14 issue)1 is considered to be distinct from HHV-8–associated multicentric Castleman’s disease owing to the absence of typical histologic findings and elevated plasma levels of interleukin-6. The histopathology of HHV-8–associated multicentric Castleman’s disease is variable, as compared with the classic descr...

OBJECTIVE To determine whether serum C-reactive protein (CRP) concentration is high in dogs with multicentric lymphoma, whether CRP concentration changes in response to chemotherapy, and whether CRP concentration can be used as a marker for relapse in dogs with multicentric lymphoma. DESIGN Cohort study. ANIMALS 20 dogs with multicentric lymphoma and 8 healthy control dogs undergoing chemot...

We postulated that multicentric glioblastoma (GBM) represents more invasiveness form than solitary GBM and has their own genomic characteristics. From May 2004 to June 2010 we retrospectively identified 51 treatment-naïve GBM patients with available clinical information from the Samsung Medical Center data registry. Multicentricity of the tumor was defined as the presence of multiple foci on th...

  Liposarcoma is a common malignant soft tissue tumor, accounting for 10% to 16% of all sarcomas. Multicentric myxoid liposarcoma is an uncommon condition. Differentiation between several primary tumors and metastasis of a single liposarcoma represents the main difficulty in diagnosis. A 47-years old woman presented with right thigh myxoid liposarcoma and underwent wide margin tumor resection. ...

Giant cell tumour (GCT) is a benign, locally aggressive tumour of the bone that accounts for 5% of primary bone tumours and 21% of benign bone tumours. This tumour more commonly presents as a single (solitary) lesion; however, it may appear with multiple (multicentric) lesions in less than 1% of the cases. According to the literature, 1-9% of solitary GCTs metastasizes to the lung, more commonl...

Papillary thyroid carcinomas (PTCs) occasionally form multiple tumor foci in different sites of the same thyroid gland. However, it is controversial whether discrete nodules of PTC arise independently (multicentric occurrence) or are seeded from a single tumor via lymphatic channels (intraglandular metastasis). In order to determine the clonal origin of multiple PTCs, we examined X-chromosome i...

A patient with progressive osteolysis of the carpal and tarsal bones with glomerulonephritis of unusual severity is described. There was a notable absence of osteodystrophy in this and other reported cases who had chronic renal failure.
