1/13. Diagnosis and treatment of cystic lymphangioma of the ascending colon by laparoscopic-assisted surgery: a case report.lymphangioma of the colon is a rare disease. Its clinical silence and absence of specific symptoms and signs make it difficult to diagnose preoperatively. We present a case of cystic lymphangioma of the ascending colon associated with constipation in a 72-year-old man and review the pertinent literature. The patient underwent laparoscopic-assisted segmental resection of the colon. The characteristic histologic appearance of cystic lymphangioma provided the definitive diagnosis. The recovery course was uneventful. Two years postoperatively, the patient was symptom-free and without evidence of tumor recurrence.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
2/13. Mast cell sarcoma with tissue eosinophilia arising in the ascending colon.Mast cell sarcoma is a rare disease. We report an unusual case of this neoplasm arising in the ascending colon of a 32-year-old Japanese woman who presented with abdominal pain. An ulcerating mass in the colon was resected, along with enlarged mesenteric lymph nodes. Two years after surgery, the neoplasm recurred as left cervical lymphadenopathy and an intra-abdominal mass. Despite predonine and radiation therapy, the disease progressed, and the patient died. The tumor cells had abundant fine granular or clear cytoplasm, and oval, lobulated, or indented nuclei. Numerous mature eosinophils were intermingled with the tumor cells. Immunohistologic studies on paraffin sections demonstrated that the majority of the tumor cells were strongly positive for CD45RB, CD68, and mast cell tryptase. They were unreactive, however, with a broad spectrum of antibodies against myelomonocytic and lymphocytic antigens. The mast cell nature of this rare type of tumor can be best identifiable by immunostains for mast cell tryptase.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
3/13. Colonic carcinoma: a case report in a child and review literature.This article reports one case of child colonic carcinoma. This is a rare disease in children which usually occurs in predisposing conditions, e.g. ulcerative colitis, familial polyposis coli, Gardner's syndrome, Turcot's syndrome and Peutz-Jegher's syndrome. The patient in this report was 12 years old. He presented with chronic intermittent colicky abdominal pain and uncorrectable iron deficiency anemia for 7 months prior to definite diagnosis. This report also reviews the literature about colorectal carcinoma in children. physicians can make an early diagnosis with a high index of suspicion if they cannot explain clearly what causes abdominal pain. Further investigations should be performed, thereby, avoiding delayed diagnosis and improving survival rate.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
4/13. Acrokeratosis paraneoplastica (Bazex syndrome) with adenocarcinoma of the colon: report of a case and review of the literature.Acrokeratosis paraneoplastica is a rare disease and is uncommon even in patients with upper aerodigestive tract cancer. We report a 63-year-old man with a 1-month history of numerous pruritic lesions and vesicles on both feet. Although he had received local therapy, progressive dense scale formation involving both palms and both soles was found. colonoscopy was performed because of hematochezia, and it revealed an early colon cancer. After the resection of the cancer, the skin lesions began to fall off dramatically. To the best of our knowledge, there is no report of acrokeratosis paraneoplastica associated with colon cancer in the literature. This is the first case report of acrokeratosis paraneoplastica associated with early colon cancer.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
5/13. Multiple inflammatory pseudotumors mimicking liver metastasis from colon cancer: report of a case.A 54-year-old man underwent an operation for colon cancer histologically diagnosed as moderately differentiated adenocarcinoma with clinical staging of Dukes C. He was prescribed carmofur for adjuvant chemotherapy. A follow-up computed tomography scan done 6 months later revealed two new low-density areas in the liver. A diagnosis of metastatic adenocarcinoma from the previous colon cancer was presumed, based on the patient's history and radiological findings, and resection of the affected area of liver was performed. Histological examination of these tumors revealed that they were inflammatory pseudotumors (IPT). The patient had an excellent postoperative course and has shown no further signs of recurrence in the 3 years since his last operation. IPT of the liver is a rare disease, for which no methods of diagnosis and treatment have been established, since it is difficult to distinguish IPT from hepatocellular carcinoma or metastatic carcinoma. We describe this case with a review of the 101 cases of IPT documented in the Japanese literature, in the hope that it will contribute to the diagnosis and treatment of this unusual disease entity.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
6/13. Purulent pericarditis caused by group G streptococcus as an initial presentation of colon cancer.Bacterial pericarditis has been recognized as a rare disease since the development of antibiotics. Usually, the disease is associated with underlying conditions or a seeding of infection elsewhere to the pericardium. Here we describe a case of group G streptococcal pericarditis as an initial presentation of colon cancer. A 52-yr-old man was admitted because of dyspnea. An electrocardiogram showed a diffuse ST-segment elevation and a two-dimensional echocardiogram showed a large amount of pericardial effusion. A pericardiocentesis was done and purulent fluid was drained. Group G streptococci was cultured in pericardial fluid. The patient was treated with antibiotics and pericardiostomy with saline irrigation. A colonoscopy revealed a small mass with moderately differentiated adenocarcinoma in rectosigmoid colon. He underwent a mucosectomy and was recovered without any complication.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
7/13. Phlebosclerotic colitis coincident with carcinoma in adenoma.Phlebosclerosis of the colon is a rare disease characterized by a thickening of the wall of the colon with fibrosis, hyalinization and calcification to the affected veins. These symptoms result in a type of ischemic colitis known as phlebosclerotic colitis. A case of phlebosclerotic colitis coincident with carcinoma in adenoma is reported. A 74-year-old Japanese woman was admitted to hospital because of a mass in her right lower abdomen. Abdominal computed tomography examination revealed linear calcifications in the wall of the cecum and the ascending colon. colonoscopy revealed dark purple mucosa with multiple ulcers in the cecum and the ascending colon. biopsy specimens showed a marked hyalinous thickening of the wall of small blood vessels in the mucosa. Phlebosclerotic colitis was suspected because of negative results with amyloid stain. Alternative ileocolic angiography showed the serpentine of the peripheral nature blood vessels and pooling at the late venous phase. Microscopic examination of the surgically resected colon revealed mucosal and submucosal fibrosis, and a thickening of the venous wall with fibrosis, hyalinization and calcification from the mucosa to the serosa, which caused a marked luminal narrowing. A small polypoid lesion was also found in the affected region and was diagnosed histologically as carcinoma in adenoma. To our knowledge, this is the first reported case of phlebosclerotic colitis complicated by carcinoma.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
8/13. intussusception in the adult--a rare disease.We present two cases of intussusception in the adult. Both cases were secondary to a benign lipoma as the lead point. These cases represent typical cases of adult intussusception, a rare disease characterized by insidious onset, vague abdominal symptoms, and elusive diagnosis. A diagnostic and therapeutic approach to adult intussusception is suggested. The need to consider this rare entity in the differential diagnosis of chronic abdominal complaints in the adult is emphasized.- - - - - - - - - - ranking = 5keywords = rare disease (Clic here for more details about this article) |
