Two Cases of ANCA-associated Pauci-immune Glomerulonephritis with Rheumatoid Arthritis / 대한류마티스학회지

Renal involvement is one of the extra-articular manifestations found in patients with rheumatoid arthritis (RA). Membranous glomerulonephopathy, membranoproliferative glomeruonophritis, secondary amyloidosis, and focal segmental glomerulosclerosis are reported as pathologic diagnoses of renal involvement. However, reports of renal involvement in patients with RA and antineutrophil cytoplasmic autoantibody (ANCA)-associated pauci-immune glomerulonephritis are rare. Recently, we experienced two patients with RA who developed azotemia and were finally diagnosed with ANCA-associated pauci-immune glomerulonephritis. Because of the rarity of these cases, we report two cases in patients with RA with a literature review.

An elderly patient with gastric adenocarcinoma developing multiple metastasis in skeletal muscle / 대한내과학회지

Gastric cancer occurs with high frequency and is a significant cause of cancer motality in Korea. The most common metastatic sites of gastric cancer are liver, lung, bone and adrenal gland. Intramuscular metastasis from gastric cancer is an rare case. Skeletal muscle is one of the most unusual sites of metastasis from any malignancy. We report an elderly patient with gastric cancer developing multiple metastasis in skeletal musle.

Relationship between Popliteal Cyst and the Intra-articular Knee Disorders

PURPOSE: To evaluate the clinical symptoms and the associated intra-articular disorders of the polpliteal cyst. MATERIALS AND METHODS: We studied 56 patients, 60 cases of the popliteal cysts which. Had been treated with excision of the cyst after arthroscopy between May 1991 and February 2000. Arthroscopic findings and clinical results of the patients who had popliteal cyst were evaluated. RESULTS: Forty nine patients of the sixty patients of who had popliteal cyst showed intra-articular disorders. Tear of the meniscus and patello-femoral arthrosis with cartilage lesions were the most frequent intra-articular lesions. In 4 cases, recurrence of the popliteal cyst was noted. Two patients had tear of the meniscus and two had no intra-articular disorders. CONCLUSION: This study revealed that popliteal cysts frequently combined with intra-articular disorders. Arthroscopy of the knee joint seems worthwhile method for the patients who had popliteal cyst
