Case of a Metastatic Solitary Fibrous Tumor Presenting as Gastrointestinal Bleeding / 대한내과학회지

Metastatic cancers of the stomach are rare. Metastatic diseases of the stomach can occur with melanoma and other primary tumors of the breast, lung, ovary, liver, colon, and testis; however, breast cancer is the most common. Other rare malignant tumors that can involve the stomach include Kaposi's sarcoma, myenteric schwannoma, glomus tumor, small cell carcinoma, and parietal cell carcinoma. On the other hand, solitary fibrous tumors of the pleura are rare soft tissue sarcomas, and most are benign; however, 13 to 36% may be malignant. Metastases may occur in extrathoracic sites, such as the liver, central nervous system, spleen, adrenal gland, and bone. We herein report a case of a 75-year-old man with previously diagnosed brain and liver metastases. He developed a stomach metastasis from a malignant solitary fibrous tumor and presented with gastrointestinal bleeding symptoms.

Idiopathic Unilateral Retroperitoneal Fibrosis Diagnosed in a Patient with Normal Renal Function and Left Flank Pain / 대한신장학회지

Retroperitoneal fibrosis is a disease characterized by proliferation of fibro-inflammatory tissue, which mainly encloses the abdominal aorta, iliac arteries and (enlarges to the retroperitoneum to surrounds) ureters. Two leading pathogenesis are an exacerbated local inflammatory reaction to aortic atherosclerosis and a manifestation of systemic autoimmune disease. Because of insidious disease course, most cases are diagnosed late when bilateral urinary obstruction caused oliguria and symptoms related to uremia. In this case, the patient complained left flank pain which might have been caused by left ureter stone, but through abdominal CT scan, the patient was diagnosed as left unilateral retroperitoneal fibrosis. Abdominal CT scan showed encircling mass around abdominal aorta and left ureter with hydronephrosis. The patient had no underlying disease and didn't take any medication; she was diagnosed as idiopathic unilateral retroperitoneal fibrosis and started prednisolone, 40 mg daily. Three months have passed since the therapy was started; most fibrous tissue was disappeared, hydronephrosis was resolved and flank pain was relieved.

A Case of Portal Vein Thrombosis by Protein C and S Deficiency Completely Recanalized by Anticoagulation Therapy / 전남의대학술지

Portal vein thrombosis (PVT) is a rare form of venous thrombosis that affects the hepatic portal vein flow, which can lead to portal hypertension. Treatment of PVT includes anticoagulants, thrombolysis, insertion of shunts, bypass surgery, and liver transplantation. Single anticoagulation therapy is not regarded as a curative treatment but can be associated with a reduction in new thrombotic episodes. We experienced a case of acute total occlusion of PVT provoked by protein C and S deficiency syndrome. PVT was completely recanalized with oral anticoagulant therapy following low molecular weight heparin therapy.

Treatment of Neurosyphilis with Ceftriaxone in a Patient Infected with Human Immunodeficiency Virus

The optimal and alternative antimicrobial regimens to treat neurosyphilis in human immunodeficiency virus (HIV) infected patients remain controversial. Little is known concerning the efficacy of ceftriaxone. A 75-year-old heterosexual man visited an outpatient clinic due to incidentally detected positive serum Venereal disease research laboratory (VDRL) and Fluorescent treponemal antibody absorbed tests in routine preoperative checkup. Because of benzathine penicillin was unavailable to use, 4-week regimen with doxycycline was started. After 2 weeks doxycycline treatment, a severe headache suddenly occurred. Cerebrospinal fluid (CSF) analysis showed mild lymphocyte-dominant pleocytosis, increased protein, and weakly reactive VDRL test. ELISA for HIV antibody and Western blot assay revealed he is infected with HIV. Initial CD4+ T cell count was 220/mm3 and the load of HIV RNA was 5,200 copies/mL. The most probable diagnosis was deemed to be neurosyphilis, considering the possibilities of Jarisch-Herxheimer reaction or doxycycline-induced pseudotumor cerebri. In the absence of procaine penicillin G in our hospital, intravenous ceftriaxone was administered and highly active antiretroviral therapy was started. After 14days of treatment, the patient no longer had a headache and the CSF profile was improved. Additional follow-up CSF analysis was done 3months after treatment. CSF pleocytosis and protein level were decreased and the CSF VDRL was converted to negative. Ceftriaxone may be a good alternative in the treatment of neurosyphilis in HIV infected patient.

A Case of Ampullary Adenomyoma Associated with Dilatations of Pancreatic and Biliary Ducts / 대한소화기내시경학회지

Adenomyoma is a nonneoplastic lesion that can be found anywhere in the gastrointestinal tract, but it's rarely found in the ampulla of Vater. To the best of our knowledge, it is a benign lesion, but most cases are misdiagnosed as carcinoma or adenoma by a preoperative endoscopic or radiologic procedure, and this leads to unnecessarily extensive surgical resection. We report here on a case of ampulla of Vater adenomyoma that resulted in biliary and pancreatic duct dilatation. The tumor was diagnosed by endoscopic papillectomy.
