RESUMO

The patient was a 50-year-old male. At the age of 48 years, he had undergone total gastrectomy and right hemicolectomy simultaneously for gastric and ascending colon cancers. Since adjuvant chemotherapy has become common practice for patients with ascending colon cancer, capecitabine was administered for 6 months. One year and 6 months after the surgery, he was diagnosed with recurrence of the ascending colon cancer at the anastomotic site and underwent local colectomy. Considering he was pathologically diagnosed as pT4a, mFOLFOX6 therapy was prescribed as postoperative adjuvant chemotherapy. On the day the 11th course of treatment was initiated, the patient complained of weakness; however, his blood test results showed no abnormalities; therefore, he was followed-up as an outpatient. Three days later, he presented to the hospital with exacerbated symptoms and was diagnosed with rhabdomyolysis due to a marked increase in CK(2,031 U/L). Rhabdomyolysis was determined to be the adverse effect of oxaliplatin because out of all the drugs prescribed to the patient, this condition is listed as a side effect only in oxaliplatin's package insert. Fortunately, outpatient treatment was enough to alleviate rhabdomyolysis. Subsequently, adjuvant chemotherapy was completed without oxaliplatin. The patient has been followed-up without recurrence for 9 months after the surgery.

RESUMO

A woman in her 80s was diagnosed with an abdominal mass during physical examination. Contrast-enhanced computed tomography(CT)revealed a tumor with contrast enhancement outside the ileocecal region of the intestine, and the ileocolic artery penetrated the tumor. No tumor was detected by colonoscopy. An endoscope could not be passed through due to an ileocecal valve stenosis. A biopsy of the ileocecal valve revealed only lymphocyte hyperplasia without adenocarcinoma components. Barium enema examination demonstrated no influx of the contrast medium from the cecum into the oral side of the intestine. Since a gastrointestinal stromal tumor in the ileocecal region was suspected, laparotomy was performed in the ileocecal region owing to the preoperative diagnosis of suspected malignant lymphoma, revealing a 5-cm elastic hard tumor outside the ileocecal wall. The tumor could not be separated from the intestinal tract. Histopathological examination revealed no lesion on the mucosal surface, although poorly differentiated adenocarcinoma infiltrated from the submucosa to the serosa. Thus, the patient was diagnosed with extramural growth-type ileocecal colon cancer. This disease is relatively rare but need to be kept in mind.

RESUMO

A man in his 50s had undergone steroid therapy for eosinophilic granulomatosis with polyangiitis(EGPA). Since an examination for malignant tumors revealed type 0-Ⅰsp(cT1aN0M0)and type 2(cT2N0M0)lesions in the proximal and mid- transverse colon, respectively, he was referred to our department. Endoscopic resection was performed on the proximal lesion. After the confirmation of curative resection, laparoscopic partial colectomy(transverse colon)and D3 lymph node dissection were performed on the mid-transverse lesion. Because of the patient's favorable postoperative course, he was discharged from the hospital on POD17. Since steroids and immunosuppressants may cause immunological abnormalities and malignant tumors, such patients should be strictly followed up.
