1/69. Laparoscopic ultrasound guidance for laparoscopic resection of benign gastric tumors.Laparoscopic excision of gastric leiomyoma is technically feasible and safe, but it may fail to localize the exact placement of the lesion because of the lack of tactile sensitivity. The authors present two cases of small gastric leiomyomas that were resected by a totally laparoscopic approach, assisted with intraoperative laparoscopic ultrasonography because the lesions could not be palpated. A gastric wedge resection with tumor-free margins was performed with an endostapler device. Use of a harmonic scalpel to divide the gastroepiploic vessels facilitated the laparoscopic procedure.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/69. Multiple piloleiomyomas associated with solitary angioleiomyoma.A 58 year-old male had reddish scattered papules strictly confined to the right side of his upper back and neck, right shoulder, and right upper arm. Additionally, he also noticed a subcutaneous nodule on his left thigh. Histopathological examinations revealed that the papules on the back, nape of the neck, shoulder, and arm were multiple piloleiomyomas, as shown by the proliferation of bundles of smooth muscles in the dermis. The subcutaneous nodule of the thigh was angioleiomyoma with a well-circumscribed lesion composed of smooth muscles and blood vessels. Ipsilaterality and segmentality of the distribution of the papules of piloleiomyomas and probable family history that his mother had similar papules with a similar distribution suggest the nevoid character of our case. Piloleiomyomas are often reported to be associated with leiomyoma of the uterus or other organs. This is the first reported case of multiple piloleiomyomas with solitary angioleiomyoma in the literature.- - - - - - - - - - ranking = 8.2122223770825keywords = blood vessel, vessel (Clic here for more details about this article) |
3/69. leiomyoma of the ciliary body. Report of 2 cases.PURPOSE AND methods: The files of the eye pathology Institute contain only two cases of leiomyoma of the ciliary body. The diagnoses were re-evaluated, applying modern immunostainings. RESULTS: The tumors were composed of interlacing fascicles of spindle-shaped cells with bright eosinophilic cytoplasm and cigar-shaped nuclei. Both tumors were well-vascularized, mostly by thin, branching capillaries. Larger vessels were also seen. In one case the tumor perforated the sclera. The tumor cells reacted with the reticulum stain and the Masson trichrome and were positive for antibodies against: smooth muscle actin (SMA), muscle specific actin (MSA), laminin and vimentin (one case). CONCLUSION: leiomyoma of the ciliary body is a rare smooth muscle cell tumor that may arise from either pericytes, ciliary - or intrascleral heterotopic muscle.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/69. Laparoscopic bipolar coagulation of uterine vessels to treat symptomatic leiomyomas.Laparoscopic bipolar coagulation of uterine vessels was performed in three women with symptomatic myomas who required conventional surgical treatment. Uterine size and dominant myoma size were assessed by ultrasonography before and after surgery. Both uterine arteries, as well as anastomosis zone of uterine arteries with ovarian arteries, were occluded in all three women. Surgery was uneventful, and patients were hospitalized for only 2 days. All women experienced improvement in symptoms with no complications. Postoperative ultrasound showed progressive reduction in size of the dominant myoma. A larger series and longer follow-up are required to evaluate long-term effects and to identify appropriate candidates.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
5/69. Preperitoneal lipoleiomyoma of the abdominal wall in a postmenopausal woman.OBJECTIVE: Extrauterine leiomyomas are rare events. These tumors may be easily misdiagnosed as ovarian tumors at the clinical investigation. We present the first case of an otherwise healthy postmenopausal woman, hysterectomized 20 years ago, who developed a preperitoneal lipoleimoyoma in the 30-year-old scar of a Pfannenstiel incision. The patient received continuous hormone replacement therapy (HRT) for 5 years with 1.25 mg conjugated estrogen and 5 mg medrogeston per day. methods: In sections of the tumor, immunohistochemical reactions with antibodies against actin, desmin, vimentin, estrogen and progesterone receptors and factor viii related antigen was performed. RESULTS: Histologic findings revealed cellular fascicles of spindle-shaped smooth muscle cells in a whorled arrangement. Mitotic figures were absent. Central degenerative changes and focal edema were observed. Between muscle fascicles, a significant amount of fat cells (20% of tumor volume) was visible. Leiomyocytes showed immunohistochemicaly positive reactions with actin, desmin, vimentin, and steroid hormone receptors. Based on these findings, the tumor was diagnosed as lipoleiomyoma. CONCLUSIONS: Origin of the tumor of smooth muscle cells of vessels located in the abdominal wall and development under influence of oral steroids seems most probable. HRT appears to promote the development of extrauterine leiomyomas in postmenopausal women.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/69. Congenital leiomyomatous epulis: a case report with immunohistochemical study.The histologic and immunohistochemical findings of an extremely rare case of congenital soft tissue mass on the alveolar ridge in an infant are reported. The lesion clinically mimicked an ordinary congenital epulis (congenital granular cell epulis, granular cell tumor of the newborn); however, histologically it consisted of a conglomerate of spindle-shaped cells, akin to smooth muscle cells, which formed interlacing and whorled fasciculi. nerve fibers with myxoid degeneration, capillaries and muscle walled small vessels intermingled with fasciculi of spindle-shaped cells. The border between the conglomerate of spindle-shaped cells and the surrounding connective tissue was not evident. Immunohistochemically, most of the spindle-shaped cells were intensely positive for antibodies to alpha-smooth muscle actin, HHF-35 and desmin. These findings suggest that the lesion was composed of mature smooth muscle cells that were of hamartomatous or choristomatous nature. The term 'congenital leiomyomatous epulis' is proposed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/69. uterine artery embolization.The use of uterine artery embolization is a new approach in the treatment of uterine fibroids. Embolization is a technique in which blood vessels that supply nutrients and oxygen to fibroids are blocked. This blockage causes the fibroid muscle cells to degenerate and form scar tissue, thus shrinking the fibroid. Usually the fibroid no longer causes symptoms. This minimally invasive procedure involves an overnight hospital stay and results in a reduction of fibroid symptoms. Most women notice the greatest improvement in the first eight weeks. This procedure has been performed only since 1990 and, therefore, long-term results are unknown.- - - - - - - - - - ranking = 8.2122223770825keywords = blood vessel, vessel (Clic here for more details about this article) |
8/69. Early pregnancy uninterrupted by laparoscopic bipolar coagulation of uterine vessels.Laparoscopic bipolar coagulation of uterine vessels (LBCUV) is reported to treat clinically symptomatic myomas that caused severe menorrhagia, but the viability of pregnancy after operation is unknown. A woman with clinically diagnosed uterine myomas, possibly with adenomyosis, had unexpected early pregnancy diagnosed at the time of LBCUV. The procedure resulted in improvement of menorrhagia to normal menstruation and reductions in the volume of both uterus and myomas. The intrauterine pregnancy was terminated at the woman's request. pregnancy may be possible after LBCUV, although none has been reported.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
9/69. Rapid enlargement of uterine myomas after laparoscopic bipolar coagulation of uterine vessels.Degenerative changes occur relatively frequently in uterine leiomyomas. Morphologic changes such as necrosis, hyalinization, and alterations in cellularity are described after uterine artery embolization. A modified method to interrupt the uterine blood supply is laparoscopic bipolar coagulation of uterine vessels (LBCUV). Although the success rate is good, occasional patients require hysterectomy because of complications or continuing symptoms. A woman with symptomatic myomas underwent LBCUV, but required hysterectomy due to rapid enlargement of myomas and intractable symptoms including pelvic pain and pressure, and acute urinary retention. The combination of degenerative and iatrogenic changes resulted in a histologic appearance resembling diffuse hyalinization and hydropic degeneration of the leiomyomas.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
10/69. Successful pregnancy in a woman with symptomatic fibroids who underwent laparoscopic bipolar coagulation of uterine vessels.OBJECTIVE: To report a case of successful pregnancy after laparoscopic bipolar coagulation of uterine vessels (LBCUV). DESIGN: Case report. SETTING: University-affiliated tertiary referral center. PATIENT(S): One woman, treated with LBCUV for symptomatic fibroids, who subsequently had a successful pregnancy. INTERVENTION(S): Laparoscopic bipolar coagulation of uterine arteries and anastomotic sites of uterine arteries with ovarian arteries. MAIN OUTCOME MEASURE(S): Patient evaluation by physical and ultrasound examinations. RESULT(S): Complete resolution of menorrhagia and dysmenorrhea was found after LBCUV. Reduction in fibroid size was seen by ultrasound. Two months later, the patient conceived a singleton pregnancy without the use of assisted reproductive technologies. The woman delivered by cesarean section. Neither myoma recurrence nor abnormality in uterine function was observed. CONCLUSION(S): Although fecundity- and pregnancy-related complications after LBCUV for managing uterine fibroids are still unclear, this first case report of successful pregnancy after LBCUV is promising. LBCUV might be a safe and effective alternative to myomectomy and hysterectomy.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
