 Abstract

- Sarcoidosis is a systemic disease of unknown cause involving multiple organs and is characterized by noncaseating granuloma. Immune thrombocytopenia (ITP) is an autoimmune disease characterized by increased peripheral platelet destruction due to the presence of an antibody to the platelet and abnormal platelet production. There is no known pathogenesis that occurs concurrently with ITP and sarcoidosis. However, considering together of 2 known pathogenesis, abnormal immune response triggers either ITP or sarcoidosis. The disease that develops first stimulates secondary disease. After development of secondary disease, they stimulate each other. A few cases of ITP associated with sarcoidosis are well documented in English; however, the disease has rarely been reported in Korea. Here, we report on a case of ITP with sarcoidosis in a 29-year-old man. He suffered from easy bruising. The chest X-ray and the contrast-enhanced computed tomography scan showed bihilar lymphadenopathy and reticulonodular infiltrates. Bone marrow study and fluoroscopy-guided percutaneous needle biopsy were performed and the patient was diagnosed with sarcoidosis and ITP. He was put on 400 mg/kg of intravenous immunoglobulin for 5 days and administered oral steroids and further follow-up will be carried out. He has shown a good response without significant bleeding event. However, administration of more oral steroid and additional follow-up is required than for single disease, whether sarcoidosis or ITP.

Abstract

- Type 1 neurofibromatosis (von Recklinghausen's disease, NF-1) is an autosomal-dominant neurocutaneous-disorder characterized by systemic cafe'-au-lait spots, multiple cutaneous neurofibromas, axillary or inguinal freckling, and Lisch nodules (pigmented iris hamartomas). Approximately 10-25% of NF1 patients have gastrointestinal neoplasms. Gastrointestinal stromal tumor (GIST) in patients with neurofibromatosis is most commonly found in the small bowel and the stomach, and approximately 60% of such patients have multiple tumors or multiple tumor sites. Although, the increased incidence of GIST in patients with neurofibromatosis is well documented in pathology literature in English, but has rarely been documented in Korea. Here, we report a case of multiple GISTs in a 48-year-old woman accompanied by NF1. She was admitted to Yeungnam University Hospital with complaints of melena and dyspnea. A contrast-enhanced computed tomography (CT) scan revealed that multiple soft tissue masses were occupying the entire peritoneal cavity. An ultrasonogram- guided biopsy was performed and the tumors were found to have been composed of tumor cells that were positive for c-kit protein. The patient was put on Imatinib mesylate treatment, and further follow-up will be carried out.
