1/91. Recurrent primary well-differentiated intrascrotal liposarcoma: case report and review of the literature.lipoma-like liposarcomas of the scrotal wall are very rarely reported neoplasms in the surgical and histopathological literature. We treated a well-differentiated liposarcoma of the inside wall of the scrotum in a 62-year-old man. Following local excision, the tumor recurred after three months, and a funiculoorchidectomy was performed. Today, 24 months following secondary surgery, the patient is completely asymptomatic and there is no evidence of tumor recurrence either on physical examination, ultrasonography or abdominal and pelvic computed tomography. In this paper we present the case and a review of the relevant literature.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/91. Paratesticular desmoplastic small round cell tumor: case report and review of the literature.desmoplastic small round cell tumor (DSRCT) is a rare neoplasm mainly affecting young males and typically located in the abdomen. prognosis is generally very poor. We report a rare case of paratesticular DSRCT in a 17-year-old boy, presenting with an isolated left scrotal mass. The patient had an excellent outcome after complete surgical resection of the tumor and adjuvant multi-agent chemotherapy. DSRCT should be included in the differential diagnosis of small round cell tumors of the paratesticular region in adolescents and young adults. Tumor resection and chemotherapy may be beneficial for these patients. Our experience and a review of the literature suggest that DSRCT located in the paratesticular region may have a better prognosis than its more frequent abdominal counterpart.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
3/91. Malignant fibrous histiocytoma of the spermatic cord: a case report.We present a case of malignant fibrous histiocytoma of the spermatic cord. An 86-year-old man was admitted to the hospital with a right painless scrotal mass. Under the diagnosis of a testicular tumor, right radical orchiectomy was performed. Grossly, the tumor firmly adhered to the spermatic cord. The right testis and epididymis were normal. The histologic diagnosis was malignant fibrous histiocytoma. There was local recurrence 2 months after surgery. The recurrent tumor was resected with the surrounding soft tissue, but the patient died 5 months after the initial operation.- - - - - - - - - - ranking = 15.681279374148keywords = testis (Clic here for more details about this article) |
4/91. Primary seminal vesicle carcinoma: an immunohistochemical analysis of four cases.Primary adenocarcinoma of the seminal vesicles is an extremely rare neoplasm. Because prompt diagnosis and treatment are associated with improved long-term survival, accurate recognition of this neoplasm is important, particularly when evaluating limited biopsy material. immunohistochemistry can be used to rule out neoplasms that commonly invade the seminal vesicles, such as prostatic adenocarcinoma. Previous reports have shown that seminal vesicle adenocarcinoma (SVCA) is negative for prostate-specific antigen (PSA) and prostate-specific acid phosphatase (PAP); however, little else is known of its immunophenotype. Consequently, we evaluated the utility of cancer antigen 125 (CA-125) and cytokeratin (CK) subsets 7 and 20 for distinguishing SVCA from other neoplasms that enter the differential diagnosis. Four cases of SVCA-three cases of bladder adenocarcinoma and a rare case of adenocarcinoma arising in a mullerian duct cyst-were immunostained for CA-125, CK7, and CK20. Three of four cases of SVCA were CA-125 positive and CK7 positive. All four cases were CK20 negative. All bladder adenocarcinomas and the mullerian duct cyst adenocarcinoma were CK7 positive and negative for CA-125 and CK20. In addition, CA-125 immunostaining was performed in neoplasms that commonly invade the seminal vesicles, including prostatic adenocarcinoma (n = 40), bladder transitional cell carcinoma (n = 32), and rectal adenocarcinoma (n = 10), and all were negative for this antigen. In conclusion, the present study has shown that the CK7-positive, CK20-negative, CA-125-positive, PSA/PAP-negative immunophenotype of papillary SVCA is unique and can be used in conjunction with histomorphology to distinguish it from other tumors that enter the differential diagnosis, including prostatic adenocarcinoma (CA-125 negative, PSA/PAP positive), bladder transitional cell carcinoma (CK20 positive, CA-125 negative), rectal adenocarcinoma (CA-125 negative, CK7 negative, CK20 positive), bladder adenocarcinoma (CA-125 negative), and adenocarcinoma arising in a mullerian duct cyst (CA-125 negative).- - - - - - - - - - ranking = 5.4204590145773keywords = neoplasm, cancer (Clic here for more details about this article) |
5/91. spermatic cord metastases from gastric cancer with elevation of serum hCG-beta: a case report.spermatic cord metastases from gastric cancer are rare. We here document a case involving a gastric cancer that mimicked primary testicular tumor because of elevation of the serum human chorionic gonadotropin-beta (hCG-beta). The possibility of metastasis or recurrence of prior malignancies should therefore be considered when the clinical features described here are encountered, although elevation of hCG-beta is rare with tumors other than those in testis.- - - - - - - - - - ranking = 18.204033461612keywords = testis, cancer (Clic here for more details about this article) |
6/91. Extramammary Paget's disease.Extramammary Paget's disease (EMPD) is an uncommon but distinctive tumor. The lesion is defined as an intra-epidermal neoplasm. The lesion may be accompanied by an invasive adenocarcinoma or in situ adenocarcinoma of apocrine glands. Visceral carcinoma may also coexist or develop. Definitive diagnosis requires biopsy of the lesion and immunohistochemical staining. In most cases of noninvasive or minimally invasive EMPD, surgical resection with clear margins and careful follow-up are recommended, since the recurrence rate is high. We review the literature and report two cases of EMPD, one involving the perineal-scrotal area and the other involving the perianal area.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
7/91. Intrascrotal rhabdomyosarcoma.rhabdomyosarcoma is the most frequent spermatic cord tumor of infants, children, and young adults, but also occurs as a primary tumor in the testis, epididumis, and testicular tunics. In the last fifteen years, 7 patients with intrascrotal rhabdomyosarcoma were treated at our institution, and an additional 155 cases were found on review of the English literature. On the basis of these 162 cases, incidence and survival statistics were calculated with particular attention to employed forms of therapy. An over-all survival of greater than 73 per cent should be obtainable with proper utilization of surgery, radiation therapy, and combination chemotherapy.- - - - - - - - - - ranking = 15.681279374148keywords = testis (Clic here for more details about this article) |
8/91. Primary lymphoma of spermatic cord.Primary lymphomas of spermatic cord are extremely rare. In a review of the world medical literature, until now, only fourteen cases of spermatic cord lymphoma have been reported, and, furthermore, they have a poor prognosis even in patients with stage I disease. Herein, we report a new case of primary non-Hodgkin's lymphoma of the spermatic cord. In August, 1993, 76-year-old man visited an urological hospital with a compaint of a right intrascoral mass, and underwent orchiectomy. Macroscopically no invasive lesion in the testis was observed, and the tumorous lesion was restricted to the epididymis. The histopathological study indicated that he suffered from primary malignant lymphoma of the spermatic cord (B-cell, diffuse medium-sized cell type). As radiographic investigations showed no other invasive lesion, the patient was diagnosed to be in stage IE. He was followed only with clinical observation, and, in August, 1996, relapsed with extensive disease in the abdoninal cavity, and was transferred to our hospital. Fourty months after the orchiectomy, he died of progression of disease irrespective of the salvage radio-chemotherapies given to him.- - - - - - - - - - ranking = 15.681279374148keywords = testis (Clic here for more details about this article) |
9/91. Giant malignant mesenchymoma of the spermatic cord with bidirectional differentiation.BACKGROUND: spermatic cord neoplasms are a rare tumor entity and, moreover, of benign behavior. Malignant tumors of the spermatic cord are mostly of mesenchymal origin. We present the unusual case of a giant malignant mesenchymoma of the spermatic cord with bidirectional differentiation into a liposarcoma and a leiomyosarcoma. CASE REPORT: A 84-year-old male patient presented with a scrotal mass on the left side which was observed growing since 1 year and misdiagnosed as scrotal hernia or testicular hydrocele. Ultrasound and computed tomography demonstrated a solid tumor suggesting a spermatic cord tumor. The patient underwent hemiscrotectomy, and the histological examination of the 2,500-gram specimen revealed a malignant mesenchymoma originating from the spermatic cord with two distinct histopathological compartments of liposarcoma and leiomyosarcoma. Because an adjuvant therapy protocol is of questionable effect and because of the patient's age no further therapy was applied. The patient was closely followed and is now, 5 years after surgery, still free of disease. CONCLUSION: Even in older patients, scrotal masses should be considered malignant tumors as long as no benign diagnosis has been proven. Although malignant mesenchymomas are rare tumors with poor prognosis, in selected cases even large tumor masses, as presented, can be cured by surgery.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
10/91. Extramammary Paget's disease of the penis and scrotum: excision, reconstruction and evaluation of occult malignancy.PURPOSE: We describe treatment and reconstruction in patients after surgery for extramammary Paget's disease of the penis and scrotum. We also investigated whether this disease causes an increased risk of undiagnosed visceral malignancy. MATERIALS AND methods: We reviewed the databases at our institution from 1996 to 2000 and identified 6 men 67 to 87 years old (mean age 76). In addition, we reviewed the literature on the clinical and pathological features of this disease. RESULTS: In our 6 patients scrotal involvement was present in 83% and penile extramammary Paget's disease was present in 33%. Each man underwent wide local excision and large skin defects were immediately reconstructed with split-thickness skin grafts. In 1 case extramammary Paget's disease had spread to the superficial inguinal nodes. At a mean followup of 29 months there has been no local recurrence and internal malignancy has not been diagnosed. Our literature review revealed 13 patients with penoscrotal extramammary Paget's disease and visceral malignancy, including 12 (92%) with malignancy of the genitourinary system. CONCLUSIONS: Extramammary Paget's disease of the penis and scrotum is a rare disease that can be managed by excision and immediate reconstruction with skin grafting or a local skin flap. disease may spread to the regional lymph nodes. Although genitourinary cancer may accompany penoscrotal extramammary Paget's disease, an extensive search for cancer of the thorax or abdomen may be unnecessary because only 1 reported case of colon cancer has been associated with penile or scrotal extramammary Paget's disease.- - - - - - - - - - ranking = 1.2613770437319keywords = cancer (Clic here for more details about this article) |
