1/10. Metastasis from small cell carcinoma of the lung producing acute appendicitis.A case of acute gangrenous appendicitis with perforation caused by metastatic small cell carcinoma of the lung in a 65 year old man is reported. The manifestation of appendicitis occurred more than 4 years after the diagnosis of the bronchogenic carcinoma. With longer survival of patients with disseminated tumors it is probable that new manifestations of those malignancies will be discovered. Acute appendicitis due to metastasis from a distant neoplasm should be considered in the differential diagnosis of right lower abdominal pain in the oncology patient.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/10. adult Wilms' tumor presenting as acute abdomen with elevated serum lactate dehydrogenase-4 and -5 isoenzymes: case report.Wilms' tumor, an embryonic neoplasm, is the most frequent renal tumor in childhood but is rare in adults. The prognosis of adult Wilms' tumor is worse than pediatric Wilms' tumor. The preoperative diagnosis of adult Wilms' tumor is extremely difficult to make because diagnostic imaging techniques, such as intravenous pyelography, computed tomography, ultrasound, renal angiography, and nuclear magnetic resonance imaging, only confirm the presence of a renal mass. diagnosis usually depends on histological characteristics, such as the presence of blastemic, epithelial, and mesenchymal components. A 27-year-old female presented with acute abdomen and with elevated serum lactate dehydrogenase (LDH) at 212 U/l (normal range: 47-140), and 2 of 5 LDH isoenzymes, namely LDH-4 at 13.6% (normal range: 6.8%-10.2%) and LDH-5 at 20% (normal range: 6.5%-9.7%). In this patient, stage I Wilms' tumor was managed by radical nephrectomy. The levels of LDH returned to its normal range. In conclusion, in cases of acute abdomen with a renal mass in young adults, the possibility of Wilms' tumor should be considered. serum LDH and its isoenzymes, LDH-4 and LDH-5, could be used as tumor markers for either differential diagnosis or monitoring the response of treatment.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
3/10. pseudomyxoma peritonei.pseudomyxoma peritonei is a relatively rare and poorly understood condition in which mucus accumulates within the peritoneal cavity. The presence of cells in the mucin, either inflammatory or neoplastic, distinguishes it from simple acellular mucus ascites caused by mucinous spillage. There is widespread seeding of the peritoneal and omental surfaces with a heavy cancerous glaze. This is principally a complication of borderline or malignant neoplasm of the ovary and/or appendix. This paper describes two cases of previously healthy women who both presented with an acute abdomen, and were diagnosed postoperatively with pseudomyxoma peritonei. In addition, literature on the clinical presentation, diagnostic procedures, and treatment options has been briefly reviewed.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
4/10. Adnexal torsion presenting as an acute abdomen in a patient with bilateral cystic teratoma of the ovary.Benign cystic teratomas are the most common ovarian neoplasms in women. Teratomas are usually benign, unilateral, and most often found in young and premenopausal women. Most are 5 cm to 10 cm in diameter when diagnosed, and on sectioning, they usually contain thick sebaceous material, tangled hair, and various dermal structures. One of the major complications seen in cystic teratoma is torsion, a partial or complete twisting of the ovarian suspensary pedicle causing severe pain, nausea, and tissue necrosis. The patient described had bilateral cystic teratomas, one uncommonly large and torsed, causing an acute abdomen. Discussion includes the diagnosis, operative management, and postoperative findings.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
5/10. Small intestinal angiosarcoma leading to perforation and acute abdomen: a case report and review of the literature.A 76-year-old man presented to the emergency room with abdominal pain and fatigue. The patient had a history of gastrointestinal bleeding. An abdominal computed tomographic scan showed collections of free air in the abdomen with obstruction of the distal small intestine and multiple masses in the liver. laparotomy revealed a widespread malignant neoplasm in the abdomen, with multiple tumor nodules in the ileal wall, mesentery, and liver. The ileal wall was perforated within the area of one of the tumors. Pathologic examination of the lesion showed a neoplasm composed of solid sheets of spindle and undifferentiated cells, forming interlacing delicate vascular channels with atypical endothelial cells. The tumor cells were positive for the endothelial marker CD31, whereas reactivity for a broad panel of epithelial and other endothelial markers was negative. This case demonstrates that although angiosarcomas of the gastrointestinal tract are rare, they should be considered in cases of intestinal perforation or severe bleeding, especially in the elderly. A broad panel of immunochemical markers might be necessary to establish the pathologic diagnosis.- - - - - - - - - - ranking = 2keywords = neoplasm (Clic here for more details about this article) |
6/10. 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) |
7/10. 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) |
8/10. 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) |
9/10. 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) |
10/10. 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) |
