3.Intra-articular Nodular Fasciitis: An Unexpected Diagnosis for a Joint Lesion: A Case Report

Pathological lesions in and around a joint can arise
from underlying dermis, subcutis, deep muscle, bone or
synovium. Clinical presentation can include joint pain,
joint swelling, palpable masses and mechanical restriction.
Whilst giant cell tumour of tendon sheath, pigmented
villonodular synovitis, synovial chondromatosis, lipoma
arborescens, juxta articular myxomas and inflammatory
arthritis are the better-known conditions of the joint.
Intra-articular nodular fasciitis, on the other hand, is less
well recognized both clinically and radiologically. It is
rarely seen in routine practice and is only described in case
reports in the literature. Due to the non-specific clinical
and radiological findings as well as the unfamiliarity with
the entity, the diagnosis of intra-articular nodular fasciitis
is usually clinched only after histological examination.
We present a case of intra-articular nodular fasciitis arising
in the knee joint which was not suspected clinically or
radiologically

Cytologic findings from five cases with variable types of Hodgkin' disease were reviewed with special emphasis on the Reed-Sternberg (R-S) cells and their variants. Typical R-S and Hodgkin's cells were mono- or binucleated, and nuclei had rounded smooth contour. Acidophilic prominent nucleoli with perinucleolar halo were conspicuous. In comparison to typical Reed-Sternberg cells, L & H (lymphocytic and histiocytic) cells in the lymphocyte predominant type tended to show pop-corn like irregular nuclear contour and to lack the prominent nucleoli. Lacunar cells in the nodular sclerosis type had multilobated nuclei with prominent acidophilic nucleoli. There was no prominent perinucleolar halo in L & H and lacunar cells. In conjuction with the number of Reed-Sternberg cells and back ground findings observed on the smears, the characteristic features of R-S cells and their variants allowed to make typing of Hodgkin's disease.

Primary pyogenic psoas abscess is rare lesion, and often is not suspected. Reasons for delayed diagnosis are unfamility with the lesion and the fact that symptoms often resemble those of primary disease of the hip. We present a case of primary pyogenic psoas abscess in child, which was diagnosed by MRI, and completely recovered after surgical treatment.

PURPOSE: Epstein-Barr virus(EBV) exists in the human population in two genetic forms, usually referred to as type 1 and type 2 which have been defined on the basis of sequence divergence in the EBNA-2 and EBNA-3 family genes. In this study, we were intended to investigate whether the subtypes of EBV in malignant lymphoma in Korea were associated with specific disease entities and geographical distribution. MATERIALS AND METHODS: Biopsy samples obtained from 18 Korean patients with malignant lymphoma including Hodgkin's disease(3 cases), B cell lymphoma(1 case), and NK/T cell lymphoma(14 cases) were analyzed to determine the subtype of EBV infected therein. DNA was extracted from formalin-fixed, paraffin-embeded tissues by ordinary method and specific viral sequences were sought using the polymerase chain reaction(PCR) and Southern blot hybridization assay. Oligonucleotide primers used for examination of EBV strain type were derived from the EBNA-3B and EBNA-3C coding regions. As a control, four cases of reactive hyperplasia were analyzed. RESULTS: The two of four reactive hyperplasia cases were associated with type 1 and the rest of two cases with both types. Among the 18 cases with malignant lymphoma, thirteen cases(72%) had type 1, one(6%) had type 2, and four(22%) had dual infections with both types. In case of NK/T cell lymphoma(14 cases) occupying 78% of 18 biopsy samples, 86%(12 cases) were associated with type 1, 7%(1 case) with type 2, and 7%(1 case) with both types. In case of Hodgkin's disease, all of three cases had both types. B cell lymphoma taking only one case of twenty two cases was determined as type 1. CONCLUSION: These observations indicated that type 1 EBV was predominant in Korean patients with malignant lymphoma, especially NK/T cell lymphoma and showed high frequency of dual viral infections(22%) in Hodgkin's disease as well as in reactive hyperplasia.

Esophageal involvement by malignant lymphoma is extremely rare. A case of follicular lymphoma of the esophagus, misdiagnosed as focal lymphoid hyperplasia (pseudolymphoma) in a 72-year-old man is presented. The esophagogram revealed diffuse narrowing of the lumen in the middle and distal portion without ulceration. The resected esophagus showed mural thickening without any remarkable mucosal change. Microscopically, the esophagus showed scattered follicular lymphoid aggregates in the submucosa, extending into periadventitial fat tissue. Most follicles were devoid of germinal center and consisted of loosely aggregated small cleaved cells without atypia. The surrounding stroma of the submucosa showed dense fibrosis entrapping the infiltrating small lymphocytes in a "indian-file" appearance. There were some reactive follicles with germinal center. In the lamina propria, many plasma cells and a few eosinophils were infiltrated. The gene rearrangement study showed rearranged band for Jk probe which confirmed monoclonal B-cell nature of infiltrated small lymphoid cells. The small cleaved lymphocytes arranged in follicles were positive for L26 and bcl-2 protein. This case demonstrated the necessity of immunophenotypic and gene rearrangement study in the diagnosis of pseudolymphoma in the digestive tract.
