Leiomyosarcoma of the bladder is a very rare tumor and it has been reported in less than 200 cases in the literature which represent 0.1% of all nonurothelial bladder tumors. We experienced a case of sarcoma of bladder that protruding into the urinary bladder in 51-year-old woman. She underwent mass excision with enucleation for the bladder function preservation. Pathologically, the mass consisted of high grade leiomyosarcoma. In immunohistochemical study, tumor showed positive reactions for smooth muscle actin and desmin. After mass excision, follow-up radiation treatment is ongoing. Herein, we present the case of a high-grade leiomyosarcoma with literature review.

Stromal sarcoma of the prostate is very rare and shows rapid growth, which consequently is related to poor prognosis. Recently, we treated two cases of prostatic stromal sarcoma: one with robot-assisted laparoscopic radical prostatectomy and the other with open radical cysto-prostatectomy with an ileal conduit. To the best of our knowledge, this is the first case report of a prostatic stromal sarcoma managed by use of a robotic procedure. Here, we report of our experiences in the treatment of prostatic stromal sarcoma by use of two different methods.

Inflammatory myofibroblastic tumor of the urinary bladder is a rare mesenchymal tumor with uncertain malignant potential. It often mimics soft tissue sarcomas both clinically and radiologically. Surgical resection in the form of partial cystectomy or transurethral resection remains the mainstay of treatment. Herein we report the case of an inflammatory myofibroblastic tumor in a young girl, which was managed by laparoscopic partial cystectomy. To the best of our knowledge, this is the first reported case of laparoscopic management of an inflammatory myofibroblastic tumor of the urinary bladder.

A 22-year-old young woman presented with dysuria and lower urinary tract symptoms that had persisted for 6 months. She was diagnosed with a tumor near the bladder neck. Transurethral resection was done under anaesthesia. The histopathological examination with immunohistochemical staining showed the tumor to be a low-grade leiomyosarcoma. Adjuvant chemoradiation was given, and the patient has been doing well for 12 months of follow-up. Nonurothelial tumors of the bladder are rare and consensus is lacking regarding their definitive treatment. Furthermore, little is known about the natural history and prognosis of this type of bladder sarcoma. We present a minimally invasive treatment for this relatively rare tumor in which bladder preservation was achieved with no evidence of local or distant recurrences during the follow-up to date.

PURPOSE: The purpose of this study was to elucidate prognostic factors for survival and clinical outcomes of rological soft tissue sarcomas (STSs). MATERIALS AND METHODS: This was a retrospective review of the medical records of 48 patients with urological STS treated from January 1982 to July 2009. Demographic and pathological characteristics were compared. Patients' demographics, clinico-pathological parameters, overall survival, and the factors expected to predict survival, such as sex, age at diagnosis, primary organ, surgical resection, metastasis, and mass size, were analyzed. We evaluated differences in survival on the basis of histological subtype by Kaplan-Meier analysis and multivariate Cox proportional hazards regression. RESULTS: The study included 34 males (70.8%) and 14 females (29.1%). The mean age at diagnosis was 47.1 years (range, 3 to 80). The most common site was the retroperitoneum (n=16), followed by the kidney (n=12), prostate (n=10), bladder (n=7), ureter (n=1), and paratesticular region (n=1). Nineteen patients (39.5%) had other organ metastases at diagnosis. The most common subtypes of sarcoma were leiomyosarcoma (50%), rhabdomyosarcoma (18.7%), and liposarcoma (8%). The remaining 11 cases had other histological subtypes (22.9%). Mean tumor size was 9.5 cm (range, 2.2 to 24). Thirty-three patients (68.7%) underwent surgical resection. The overall survival rate at 5 years was 51.4%. In the univariate and multivariate analysis, surgical resection, primary tumor site, and metastasis at diagnosis remained significant predictors of prognosis. Patients with retroperitoneal sarcoma had a higher overall survival rate by 5 years compared with patients with other organ sarcoma. CONCLUSIONS: The overall survival rate at 5 years was 51.4%. Surgical resection, primary tumor site, and metastasis at diagnosis remained significant predictors of prognosis.

Kaposi's sarcoma (KS) is a multifocal hemorrhagic sarcoma that occurs primarily on the extremities. KS limited to the penis is rare and a well-recognized manifestation of acquired immune deficiency syndrome (AIDS). However, KS confined to the penis is extraordinary in human immunodeficiency virus (HIV)-negative patients. We present the case of a 68-year-old man with a dark reddish ulcerated nodule on the penile skin, which was reported as a nodular stage of KS. We detected no evidence of immunosuppression or AIDS or systemic involvements in further evaluations. In his past medical history, the patient had undergone three transurethral resections of bladder tumors due to urothelial cell carcinoma since 2000 and total gastrectomy, splenectomy, and adjuvant fluorouracil/cisplatin chemotherapy for 7 months due to advanced gastric carcinoma in 2005. The patient was circumcised and has had no recurrence for 2 years.

To our knowledge, this is the first report of case of high-grade endometrial stromal sarcoma metastasized to the stomach. Endometrial stromal sarcoma is very rare, accounting for 0.2% of female genital tract malignancies. High-grade endometrial stromal sarcoma demonstrates more frequent infiltration into the muscle layer of the uterus or metastasis to other organs, having a poorer prognosis than low grade disease. During its clinical course, endometrial stromal sarcoma may involve ovary, fallopian tube and pelvic cavity. Distant metastasis to lung, liver, bladder, breast, heart, brain and bones have been reported. However, to the best of our knowledge, high-grade endometrial stromal sarcoma presenting with gastric metastasis has never been reported. We now report a case of a 52-year-old woman with previously diagnosed lung metastasis having stomach metastasis from endometrial stromal sarcoma of the uterus.

Endometrial stromal sarcoma (ESS) is a mesenchymal neoplasm that usually occurs as a primary tumor of the uterine corpus, but rarely arises in other sites, such as the ovary, pelvic cavity, mesentery, omentum and intestine. Herein, we present a rare case of low-grade ESS presented as prevesical mass. A 60-yr-old woman who had undergone total hysterectomy for endometriosis eleven years ago was presented with incidentally detected prevesical pelvic mass. Since malignant transformation of urachal remnants was possible, the mass was suspected to be a urachal tumor. Extraction of the mass was performed, and the histopathologic diagnosis was low-grade ESS. In summary, prevesical tumor is rare but in patients with endometriosis, we suggest endometriosis and its possible malignant changes should be taken into account in the differential diagnosis of prevesical mass.
