RESUMO
Sweet’s syndrome (SS) is an autoimmune-mediated acute febrile neutrophilic dermatosis with a number of possible etiologies, including infection, malignancy, and drug reactions. In contrast to its original description, it can rarely involve extracutaneous organs, including the central nervous system, cardiovascular system, lung, liver, gastrointestinal tract, spleen, and bone. To our knowledge, there have been only three cases of SS accompanied by acute kidney injury worldwide, and this is the first report in which the patient recovered completely from acute kidney injury as well as cutaneous lesions with early steroid administration. Here, we report a case of SS with acute kidney injury in a patient with myelodysplastic syndrome (MDS) whose skin lesions and renal function recovered fully with early diagnosis and steroid therapy along with a review of the relevant literature.
RESUMO
This report describes a case of a 62-year-old woman with microscopic polyangiitis (MPA) who developed acute spinal subdural hemorrhage. MPA was confirmed by positive autoantibodies to myeloperoxidase and focal segmental necrotizing and pauci-immune crescentic glomerulonephritis on renal biopsy. She did not recover from paraplegia due to acute spinal subdural hemorrhage, despite decompression operation and aggressive immunosuppression. Although spontaneous spinal hemorrhage in MPA patients is very rare, the prognosis for such patients is poor. Considering the possibility of ongoing vasculitis activity in extra-renal organs, clinicians should be very cautious to attenuate the strength of immunosuppressant drugs, even in patients with chronic or irreversible renal pathology.

PURPOSE: Adverse cutaneous reactions to antituberculous drugs (ATD), such as maculopapular eruption (MPE), are the most common causes of discontinuation of scheduled treatment of tuberculosis. We previously reported that tumor necrosis factor (TNF)-alpha genetic polymorphism -308G/A is significantly associated with ATD-induced hepatitis. This study aimed to investigate associations between TNF-alpha -308G/A and ATD-induced MPE. METHODS: Patients with ATD-induced MPE and controls without any adverse reactions to ATD were recruited from the database of the Adverse Drug Reaction Pharmacogenomic Research Group database of Korea. We compared the genotype frequency of TNF-alpha-308G/A between patients with ATD-induced MPE and ATD-tolerant controls. RESULTS: A total of 69 patients with ATD-induced MPE and 229 control subjects were enrolled for this study. There were no significant differences in genotype frequency between the patients and the controls, suggesting lack of associations between TNF-alpha-308G/A and ATD-induced MPE. CONCLUSION: The TNF-alpha genetic polymorphism -308G/A may not be related to the development of ATD-induced MPE, in contrast to ATD-induced hepatitis. These findings suggest that associations between TNF-alpha-308G/A and ATD-induced adverse reactions can be phenotype-specific.

A bezoar is a mass formed by the accumulation of digested food. A biliary bezoar, namely a bezoar formed in the bile duct, is rare, which occurs mostly in patients who formerly underwent cholecystectomy. It appears that incompetent sphincter produces occasional reverse flow of foreign bodies including undigested food from the alimentary canal into the bile tract. Surgical treatment is used for huge biliary bezoar which is too huge to be removed by nonsurgical treatment. Extracorporeal shock wave lithotripsy (ESWL) is mostly used to fragment renal or urinary calculi, but may be sparingly used against biliary calculi. This is to report the rare case of a patient with biliary bezoar who formerly underwent open cholecystectomy and choledocoduodenostomy. The patient's huge biliary bezoar was removed by ESWL and the successive execution of endoscopic retrograde cholangio pancreatography (ERCP). ESWL is expected to be a comparatively safe and convenient solution to huge biliary bezoars.

Skin metastasis from internal carcinoma rarely occurs and it has an incidence of 0.7% to 9%. Although the prognosis of the skin metastases varies considerably depending on the type of the primary malignancy, presence of metastatic skin cancer usually implies a widespread systemic disease and a high mortality. A 50-year-old Korean male patient visited Dankook University Hospital for evaluation of skin rash on his whole abdomen of about 1 month's duration. He had undergone laparoscopy-assisted distal gastrectomy due to early gastric cancer about 3 months ago. He did not complain of any noticeable symptoms like febrile sense or pruritus. Skin biopsy was performed on the periumbilical area at previous port site and around the scar. Microscopic examination revealed multiple malignant cells in lymphatic spaces, consistent with metastatic carcinoma. He was therefore diagnosed with isolated skin metastasis from early gastic cancer. Because of patient's poor liver function, systemic chemotherapy could not be performed and only best supportive care was provided. Herein, we report a rare case of cellulitis-like skin metastasis from early gastric cancer with a brief review of the literature.

The World Health Organization (WHO) defines a perivascular epithelioid cell tumor (PEComa) as a mesenchymal neoplasia composed of perivascular epithelioid cells with characteristic morphological and immunohistochemical features. They are rarely malignant. Indeed, only a few cases have been reported in the English literature, and this is the first case of PEComa reported in Korea. A 64-year-old man presented with an abdominal mass and peritoneal seeding. The patient underwent mass excision with descending colon resection and anastomosis. The primary mass and peritoneal seeding was diagnosed as a PEComa histopathologically. Seven months later, he developed liver metastasis and aggravated peritoneal seeding. Here, we report a case of malignant PEComa of the omentum.
