RESUMO

Gastrointestinal involvement is a rare manifestation of systemic amyloidosis, and few reports have been published on localized amyloidosis of the colon. Only one case report has been published on the long-term prognosis of localized colorectal amyloidosis, and there are no previous reports on localized colorectal ATTR amyloidosis. Here, we report an 80-year-old male with localized colorectal wild-type ATTR amyloidosis who presented with edematous mucosa with vascular changes throughout the colon. He did not exhibit any symptoms or endoscopic exacerbation for 8 years after diagnosis. However, after 8 years, he developed early stage colorectal cancer and cytomegalovirus-associated ulcer. He was treated with endoscopic submucosal dissection, which was relatively challenging due to his hemorrhagic condition and poor elevation of the submucosa caused by amyloid deposits. Since the tumor was completely resected, he will undergo regular follow-up. Our review of 20 previous cases of localized colorectal amyloidosis revealed its clinical features and long-term prognosis. Specifically, ours is the second case of a diffuse pan-colon type of colorectal localized amyloidosis, which may lead to various complications, such as colorectal cancer, over a long period of time, and thus, regular follow-up is necessary.

RESUMO

Tumor lysis syndrome (TLS) is a life-threatening oncological emergency. Only one TLS case has been reported in patients with esophageal cancer. We report the case of a 61-year-old man with recurrent spontaneous TLS caused by esophageal cancer. He was admitted to our hospital to investigate low back pain and dysphagia. Endoscopy and computed tomography revealed esophageal cancer with multiple liver and bone metastases. He was diagnosed with laboratory TLS based on high serum uric acid and phosphorus. After intravenous fluids and allopurinol were administrated, chemotherapy with 5-fluorouracil and cisplatin was started the next day. Although he transiently developed clinical TLS, it was resolved with conservative treatment. However, mild renal dysfunction was prolonged and cisplatin was reduced in the second course. As a consequence, recurrence of spontaous TLS (sTLS) was induced at the end of the course. In the third course, docetaxel was added to the regimen, and since then the patient have not develop sTLS. To the best of our knowledge, this is the first report regarding recurrent sTLS developed on the basis of solid tumors and was successfully controlled by chemotherapy. Although TLS complications are rare in esophageal cancer, early diagnosis and the adjustment of regimen resulted in stable chemotherapy.

RESUMO

Pure erythroid leukemia (PEL) is an extremely rare type of acute myeloid leukemia (AML), accounting for fewer than 1% of all AML cases. A 72-year-old man presented with severe fatigue. His bone marrow aspiration contained myeloperoxidase negative abnormal cells that were aggregating and depicting epithelial adhesion, suggesting the possibility of solid tumor metastasis. His general condition deteriorated during medical diagnosis, and he died soon after starting chemotherapy. PEL appeared to be the definitive diagnosis after evaluating the histopathological findings, which were obtained after his death. With atypical morphological features, immunophenotypic and karyotypic approaches must be integrated for PEL assessment.

RESUMO

Intestinal ischemia is a rare complication of Takayasu arteritis (TAK), which often requires colectomy. We report the case of a 27 year-old man with ulcerative colitis (UC), who was admitted to our hospital due to abdominal pain. Computed tomography revealed an edematous wall of the ascending colon with ascites and a thickened aortic wall with mild stenosis of the superior mesenteric artery (SMA), suggesting large vessel vasculitis, especially TAK. Colonoscopy revealed acute ischemic colitis associated with mild stenosis of the SMA caused by TAK, but there was no worsening of UC. The patient was successfully treated with conservative therapy.
