1/22. Giant mesenteric lipoma.Mesenteric lipoma is a rare benign tumor of mature fat cells. Asymptomatic abdominal mass, progressive abdominal distension, and intraperitoneal radiolucent fat density mass on computed tomography are the main diagnostic criteria. Main differential diagnosis is lipoblastoma or lipoblastomosis. Treatment is surgical excision. As an unusual case, a 3-year-old boy with a giant mesenteric lipoma is presented in this report.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/22. recurrence of giant adrenocortical carcinoma in the contralateral adrenal gland 6 years after surgery: report of a case.We report herein the case of a patient in whom a giant adrenocortical carcinoma was found to have recurred in the contralateral adrenal gland and intrapelvic cavity 6 years after his initial operation. A 52-year-old man had consulted our hospital complaining of right upper abdominal pain and weight loss, and was subsequently diagnosed as having a giant adrenal tumor by computed tomography scans and echography. A laparotomy was performed and the tumor, located in the right retroperitoneal cavity and infiltrating the liver and right kidney, was surgically removed. The lesion, 29 x 19 x 10 cm in size and 4700 g in weight, was histopathologically diagnosed as an adrenocortical carcinoma. Adjuvant chemotherapy with mitotane was given for 3 months and his postoperative course was uneventful until a recurrence in the contralateral adrenal gland and peritoneal cavity was found 6 years later. The second resection was successful, and he is currently alive with no further sign of recurrence 8 years after his first operation. We report this unusual case as it provides much useful information on the biological features of adrenocortical carcinomas and the state of tumor dormancy.- - - - - - - - - - ranking = 6keywords = giant (Clic here for more details about this article) |
3/22. Giant cystic lymphangioma of the small bowel mesentery: report of a case.We herein describe the case of a 48-year-old man who presented to our hospital with abdominal distension and pain. Preoperative studies including abdominal ultrasonography and computed tomography failed to determine the cause of the pain. At laparotomy, a giant cystic tumor of the small bowel mesentery was found. Histologically, the tumor was diagnosed as a cystic lymphangioma. Although mesenteric lymphangiomas are rare, especially in adults, they should be considered as a possible cause of acute abdomen.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
4/22. Torsion of a giant mesenteric lipoma.Mesenteric lipoma is a rare benign neoplastic condition that can grow to be very large and mimic other midgut fatty tumors. These benign tumors can cause various gastrointestinal symptoms such as obstruction and abdominal pain. We report the case of a 9-year-old boy who presented with a small bowel obstruction caused by torsion of a large mesenteric lipoma. This is an important but unusual tumor and should be considered in the differential of fatty lesions within the mesentery.- - - - - - - - - - ranking = 4keywords = giant (Clic here for more details about this article) |
5/22. Primary intra-abdominal malignant fibrous histiocytoma. Case report and literature review.Malignant fibrous histiocytoma is a pleomorphic soft tissues sarcoma usually found in the extremity and in the retroperitoneum. The primary intra-abdominal localization of this tumour is very rare and only thirty-five previous reports are present in the world medical literature. The Authors report a case of giant malignant fibrous histiocytoma of the mesentery, which is treated by surgical removal plus adjuvant chemotherapy.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
6/22. Giant broad ligament leiomyoma.Giant fibroids are known to arise from the uterus, but occasionally from the broad ligament also. A case of giant broad ligament fibroid is reported for its rarity, and the diagnostic difficulties it posed are discussed.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
7/22. Tuberculous peritonitis mimicking peritonitis carcinomatosis: a case report.A 13-year-old girl presented with non-specific symptoms of peritonitis, low grade fever and missed her normal menses. Computed tomography of her abdomen and pelvic cavity showed omental cake and a generalised thickened peritoneum. An elevated serum cancer antigen-125 (CA-125) level of 1248.5 U/ml was also noted and a diagnosis of peritonitis carcinomatosis was first suspected. Diagnostic laparoscopy revealed multiple tubercles over the whole peritoneum and the pathology report described granulomatous nodules with giant cells and epithelioid cells. culture of the ascitic fluid revealed mycobacterium tuberculosiswhich resulted in a final diagnosis of tuberculous peritonitis. The patient's fever and abdominal distension gradually subsided after anti-tuberculosis treatment. The serum CA-125 level also decreased significantly to 10.2 U/ml after treatment. CONCLUSION:cancer antigen-125 levels may serve as a potential follow-up marker of disease activity and treatment response in tuberculous peritonitis.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
8/22. Hyalinizing spindle cell tumor with giant rosettes of the omentum.We report the first case of a hyalinizing spindle cell tumor with giant rosettes of the omentum. The mesenchymal tumor arises from a multiplication of fibroblastic cells containing large rosette-like structures composed of a central collagen core surrounded by plump oval to spindle tumor cells. A 38-year-old woman exhibited the symptom of abdominal pain in the right side, with a correlated sensation of a mass in the same area. A tumor consisting of both solid and cystic cytologic features was subsequently diagnosed, on the right side of the uterus. Her serum level of CA-125 was only slightly elevated. Surgical intervention indicated that the tumor originated from lower pole of the omentum and the histological diagnosis was hyalinizing spindle cell tumor with giant rosettes. The metastatic potential of this type of tumor is considered similar to that of the metastatic low-grade fibromyxoid sarcoma, which indicated the need for careful clinical follow up of this case.- - - - - - - - - - ranking = 6keywords = giant (Clic here for more details about this article) |
9/22. Atypical pleomorphic epithelioid angiomyolipoma localized to the pelvis: a case report and review of the literature.AIMS: angiomyolipoma is the most common mesenchymal tumour of the kidney. It has been reported in several other sites outside the kidney, mainly in the liver. We report the first case of atypical pleomorphic angiomyolipoma in a man, arising from the pouch of Douglas and extending to the entire abdominal cavity. methods: A 17-year-old man underwent a complete resection of a giant abdominopelvic mass. The tissue was formalin fixed and paraffin embedded and 4 micro m thick histological sections were stained with haematoxylin-eosin. Immunohistochemical stains for HMB-45, smooth muscle actin, vimentin, calponin, S100 and desmin were performed. Sections for electron microscopy were also prepared. RESULTS: Microscopic examination revealed a neoplasm composed of pleomorphic epithelioid cells with atypical features, immunoreactive for HMB-45, MART-1, actin, vimentin and calponin, while S100 protein and desmin stains were negative. Ultrastructurally, the tumour cells showed prominent nucleoli, vacuolated cytoplasm, and some premelanosomes. A diagnosis of atypical pleomorphic epithelioid angiomyolipoma was then made. CONCLUSIONS: To date five patients with abdominal epithelioid angiomyolipoma have been described in the literature. All were women. Three of the five patients reported developed metastasis, while our patient is still free of disease at 16 months of follow-up. Clear prognostic pathological features have not been identified.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
10/22. Small bowel volvulus due to giant mesenteric lipoma.We report on a 14-year-old girl with acute intestinal obstruction due to volvulus of the small bowel caused by a giant mesenteric lipoma. To the best of our knowledge, this presentation of a mesenteric lipoma is unknown in the previous paediatric literature.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
