11/18. Haemangiopericytoma of greater omentum. A rare cause of acute abdominal pain.Haemangiopericytoma (HPT) is a rare neoplasm that can occur in any part of the human body. In this report, we describe the case of a patient with sudden severe upper abdominal pain caused by primary HPT in the greater omentum.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
12/18. A case of group B streptococcal pyomyositis.The group B streptococcus is an opportunistic pathogen that causes a variety of serious infections including bacteremias, puerperal sepsis, and neonatal meningitis. Group B streptococcal infections of muscle are rare. We report here an unusual case of group B streptococcal pyomyositis. pyomyositis arises predominantly from infections caused by staphylococcus aureus and, occasionally, streptococcus pyogenes. Because of the rarity of pyomyositis in temperate climates, the common lack of localizing signs or symptoms, and the frequently negative blood cultures, considerable delay often precedes the diagnosis of pyomyositis; in fact, the infection has been initially misdiagnosed as muscle hematoma, cellulitis, thrombophlebitis, osteomyelitis, or neoplasm. diagnosis may be greatly aided by radiologic techniques that can demonstrate the sites of muscle enlargement and the presence of fluid collections. The response to antibiotics is usually rapid, but resolution of the infection may require aspiration of deeply situated muscle abscesses. This report describes a diabetic patient with an unusual presentation of pyomyositis that mimicked an acute abdomen.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
13/18. Acute abdominal conditions in mesenteric lymphangioma.Mesenteric lymphangiomas are rare benign tumors that occur in the abdominal cavity attached to the mesentery of the small or large bowel. They are no longer believed to be neoplasms, but may be a result of congenital failure of the original lymphaticovenous system. I have reported four cases of mesenteric lymphangioma causing an acute abdominal condition. Segmental resection of the intestine and the cystic mass was done in all patients, and all recovered uneventfully. There were no postoperative complications or recurrences.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
14/18. Cryptorchism with a large abdominal mass--a challenge.The undescended testis is associated with an increased incidence of testicular malignancy. The position of the undescended testis is related to the likelihood of carcinogenesis, with the intra-abdominal testis having the highest malignant potential. We present 3 patients to illustrate this tendency and to highlight the unusual presentation as an "acute abdomen".- - - - - - - - - - ranking = 1.3499754426492keywords = malignancy (Clic here for more details about this article) |
15/18. High-grade endometrial stromal sarcoma in a 16-year-old girl.Endometrial stromal sarcoma (ESS) is a rare uterine malignancy with a variety of morphologic characteristics and clinical courses. We describe a case of high-grade malignant ESS in an adolescent girl, arising in a rudimentary uterine horn and presenting symptoms of an acute abdomen. The patient underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy and omentectomy due to a stage IVA high-grade ESS. An adjuvant chemotherapy and radiotherapy treatment was recommended, but 10 days after her discharge the condition of the patient deteriorated, with diffused metastases into the lungs and the abdomen, and finally she succumbed to the disease 1 month after her first admission to the hospital.- - - - - - - - - - ranking = 1.3499754426492keywords = malignancy (Clic here for more details about this article) |
16/18. A case of type 3 choledochal cyst masquerading as acute abdominal pain.A type 3 choledochal cyst, presenting with acute abdominal pain attacks, was diagnosed in a 24-year-old man. Previously he had undergone exploratory laparotomy for acute abdominal pain, which had proved negative. An internal drainage procedure was chosen as the surgical procedure. The patient is under constant follow-up because of the risk of a malignancy developing.- - - - - - - - - - ranking = 1.3499754426492keywords = malignancy (Clic here for more details about this article) |
17/18. The laparoscopic approach of a torsion of a benign mature ovarian teratoma: a case report and review of the literature.Benign mature teratomas account for approximately 10-15% of all ovarian neoplasms. Many patients with these dermoid cysts are asymptomatic. The most frequent complication is torsion of the teratoma (in 3,5% of the cases). In a 26-year female patient admitted for severe, acute abdominal pain, a computerized abdominal tomography in accordance with the clinical characteristics of the abdominal examination, was highly suggestive for a torsion of a teratoma. The diagnose was confirmed by a celioscopic operative approach and the teratoma with the left tubo-ovarian complex was successfully removed laparoscopically.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
18/18. Solid and papillary neoplasm of the pancreas: a case presentation.Solid and papillary tumors of the pancreas are very rare malignancies, more commonly occurring in young women. They usually present as asymptomatic, large abdominal masses, and different from the most common neoplasm of the pancreas, which is the adenocarcinoma, these tumors have a high percentage of curability when treated by complete surgical resection. (6) For this reason, when the diagnosis of Frantz's tumor is made or strongly suspected, every attempt should be made for complete surgical excision since curability is high and radiotherapy and, or chemotherapy are of no use for its treatment.- - - - - - - - - - ranking = 5keywords = neoplasm (Clic here for more details about this article) |
