1/26. Low-grade fibromyxoid sarcoma: clinicopathologic case report with review of the literature.Low-grade fibromyxoid sarcoma is a rare, benign-appearing soft tissue neoplasm with an aggressive clinical course characterized by multiple local recurrences over several years, with ultimate spread to lung and occasionally to bone. Thus far, a total of 24 cases of low-grade fibromyxoid sarcoma have been reported in the literature. The authors present an additional case that grossly and microscopically emphasizes a pronounced lobular pattern of contrasting areas of cellularity showing high proliferative activity, as demonstrated by a proliferation marker, Ki 67 with MIB-1, and hypocellular areas with prominent myxoid component and abundant collagen fibrils. There was predominance of delicate capillary-sized stromal vessels with collagenized walls in both cellular and myxoid areas. The unusual features in this case were osseous metaplasia, prominent intranuclear pseudoinclusions, dna tetraploidy, and membrane-bound intracytoplasmic fat vacuoles. The immunoprofile and cytologic and ultrastructural features are described. After the excision of the tumor, the patient was treated with radiotherapy without chemotherapy. The patient has been observed for 26 months and is alive without the evidence of disease. The postoperative follow-up with axial computed tomography at 24 months showed no evidence of disease, except postsurgical fibrotic changes.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/26. Successful treatment of recurrent pelvic desmoid tumour with tamoxifen: case report.The case report of a young woman with recurrent pelvic desmoid tumour successfully treated with tamoxifen is described. The desmoid tumour recurred within 6 months after the initial exploratory laparotomy. tamoxifen therapy led to complete relief of ascites within 2 months and complete tumour regression by the end of the fourth month, and the patient has remained stable for 6 years. Without sacrificing pelvic organs or major vessels and preserving reproductive ability, tamoxifen should be considered as the first drug of choice in such a recurrent condition.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/26. Angiomyomatous hamartoma and associated stromal lesions in the right inguinal lymph node: a case report.Angiomyomatous hamartoma is a rare disease with a predisposition for the inguinal lymph nodes. A 51-year-old male patient visited a local hospital because of a right inguinal mass, measuring 3 x 4 cm in size, which was resected. The resected specimen showed irregularly distributed thick-walled vessels in the hilum, extending into the medulla and focally into the cortex of the node, eventually becoming more dispersed and associated with smooth muscle cells splaying into sclerotic stroma. These findings are compatible with an angiomyomatous hamartoma. Another tumor-like mass appeared shortly after the resection at the same location, but was not an angiomyomatous hamartoma, rather it was composed of edematous stromal tissue with proliferating smooth muscle cells. The stromal component included thick-walled blood vessels and lymphatics. Although it could not be determined whether these associated changes in the surrounding stroma are a cause or an effect of angiomyomatous hamartoma, they indicate the clinical difficulty in determining an appropriate area of resection and may provide clues to the pathogenesis of angiomyomatous hamartoma.- - - - - - - - - - ranking = 11.926334041695keywords = blood vessel, vessel (Clic here for more details about this article) |
4/26. Surgical treatment of the radiation injured bowel.Over the last 10 years, 9 patients treated by surgical procedure for radiation injuries of the bowel were studied with the following conclusions: The damage to the small intestine caused by external irradiation leads to adhesion of the bowel, perforation and postoperative anastomotic dehiscence if the irradiated bowel is used in the anastomosis. Surgical treatment for the small intestine is resection of the damaged loop. In order to determine the extent of the resection it is important that during the operation fibrosis and obstruction of vessels in the submucosa and subserosa is examined by biopsy. On the other hand, rectal ulcer and/or rectovaginal fistula is chiefly caused by intracavitary application plus external irradiation. For these lesion Hartmann operation or colostomy is performed, and the postoperative course is uneventful.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/26. leiomyosarcoma of the uterus with a florid intravascular component ("intravenous leiomyosarcomatosis").A leiomyosarcoma of the uterus in a 54-year-old woman exhibited striking involvement of large vessels of the myometrium and broad ligament on both gross and microscopic examination. The pattern of vascular involvement resembled that seen in intravenous leiomyomatosis. Imaging studies showed recurrent tumor within the inferior vena cava 3 months after hysterectomy. To our knowledge, this is the first reported such case in the literature, for which we propose the designation intravenous leiomyosarcomatosis of the uterus.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/26. Congenital pelvic arteriovenous fistulas: report of a case and review of the literature.The fifth male patient with a congenital arteriovenous fistula of the pelvis is described. This disorder has been reported previously in 11 female patients. Most patients gave a long history of symptoms before a diagnosis was made. Preoperative angiography is vital to delineate the vascular supply to the fistula and operative treatment consists of ligation of the feeding vessels and resection of the fistula.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/26. Aggressive angiomyxoma of the pelvis: case report and review.OBJECTIVE: To report a case of recurrent aggressive angiomyxoma managed by a team composed of a radiologist, general surgeon, and reproductive endocrinologist, with a literature review which focuses on histologic differences between various types of myxomas. STUDY DESIGN: Case report and literature review. RESULTS AND CONCLUSIONS: The proband patient has an apparent cure, but this particular type of myxoma shows a proclivity for recurrence, sometimes years after resection. Therefore, long-term follow-up with MRI or CT scans is necessary. Preoperative management with vessel embolization and creation of gonadal suppression facilitates the surgical approach, which usually can be via a perineal, extraperitoneal route.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/26. lymphangioleiomyomatosis initially presenting with abdominal pain: a case report.lymphangioleiomyomatosis (LAM) is a rare idiopathic disease characterized by hamartomatous smooth muscle proliferation of the lymph node, lymphatics, blood vessels as well as airways within the lungs, mediastinum and abdomen. It exclusively affects women during the reproductive period. Though extrapulmonary manifestations have been reported, the initial presentation of LAM as abdominal pain is extremely rare. To our knowledge, there are only three cases with LAM presenting first with abdominal symptoms so far [Chest 106 (1994) 267; Eur J Radiol 14 (1992) 192; Eur J Surg 157 (1991) 36]. We describe a case of LAM suffering from abdominal pain followed by pulmonary symptoms and the diagnosis was not made until pathohistological examination.- - - - - - - - - - ranking = 10.926334041695keywords = blood vessel, vessel (Clic here for more details about this article) |
9/26. Aggressive angiomyxoma. A report of four cases occurring in men.Aggressive angiomyxoma is a distinctive, locally aggressive but nonmetastasizing soft tissue tumor of the pelvic soft tissues and perineum. This rare tumor occurs almost exclusively in adult women. We report four cases occurring in adult men, one each located in the scrotum, inguinal region, spermatic cord, and pelvis. The tumors were infiltrative, and were composed of fibromyxoid matrix sparsely populated by bland-looking spindled and stellate cells with delicate cytoplasmic processes. There were haphazardly scattered small and large blood vessels, some of which exhibited hypertrophy or hyalinization of the wall. Immunohistochemically, the stromal cells stained consistently for vimentin and variably for muscle-specific actin, but not alpha-smooth muscle actin, desmin, and S-100 protein. None of the four tumors recurred in follow-up times from 11 months to 6 years, although two previously reported cases in men recurred. This uncommon tumor occurring around the genital region in men merits wider recognition because of its potential for recurrence. It should be distinguished from benign tumors with low risk of recurrence on one hand, and from malignant myxoid tumors with metastatic potential on the other.- - - - - - - - - - ranking = 10.926334041695keywords = blood vessel, vessel (Clic here for more details about this article) |
10/26. osteosarcoma of the pelvis. A clinical and histopathological study of twenty-five patients.Twenty-five patients who had an osteosarcoma of the pelvis were treated at the University of florida between 1967 and 1990. Two of these patients had underlying Paget disease, and five had received previous radiation therapy to the pelvis. Common problems in this series of patients included delays and errors in establishment of the diagnosis, underestimation of the extent of the tumor on the radiographic staging studies, histopathological findings of local extension next to and into pelvic structures, widespread invasion into major pelvic veins, and microscopic foci of tumor in otherwise normal tissue. These problems led to difficulty in gaining local control of the tumor with any type of operative procedure. Of the eighteen patients who had a resection, only four had a contamination-free wide margin, and a local recurrence developed in thirteen. Only one patient, who had no evidence of disease eleven years after treatment, was alive at the time of writing. Because of the tendency for venous invasion, the radiographic staging studies should include a thorough evaluation of the blood vessels adjacent to the tumor.- - - - - - - - - - ranking = 10.926334041695keywords = blood vessel, vessel (Clic here for more details about this article) |
