Scrotal leiomyomas with atypical bizarre nuclei are rare, which might be misdiagnosed as malignant tumor. We describe a case of scrotal bizarre leiomyoma in a 65-yr-old man. The tumor was a 1 cm-sized, well circumscribed, oval mass arising from the tunica dartos muscle. Histologically, it was formed by whorling bundles of fusiform cells with occasional atypical, pleomorphic nuclei and pseudoinclusions. Mitosis was not found. Although morphologically atypical, scrotal bizarre leiomyomas take on a biologic behavior not different from that of conventional leiomyoma, they should be distinguished from leiomyosarcoma to avoid unnecessary treatment.

OBJECTIVETo investigate the clinical and pathological features, diagnosis and treatment of cystic lymphangioma of the spermatic cord.

METHODSOne case of cystic lymphangioma of the spermatic cord in a 71-year-old patient was retrospectively analyzed and the relevant literature was reviewed.

RESULTSThe patient, presented with spermatic cord hydrocele, was treated by local excision of the tumor, which was pathologically diagnosed as cystic lymphangioma. No relapse was found during a 3-month follow-up after the operation.

CONCLUSIONLymphangioma of the spermatic cord is a benign tumor. Preoperation ultrasonography and CT are important for determining the location and nature of lymphangioma. Surgical excision is an effective option for the treatment of cystic lymphangioma of the spermatic cord.

OBJECTIVETo study the clinicopathologic features and treatment of Paget's disease of the scrotum.

METHODSFifteen cases of Paget's disease of the scrotum, pathologically diagnosed and successfully treated by surgery from 1987 to 2003, were studied retrospectively.

RESULTSTypical pathological features were observed in all the patients. Thirteen cases were followed up for 0. 5 approximately 13 years, of whom 1 case relapsed within 3 years, 2 died of metastasis after 2 years, and 3 died of cardiovascular diseases, with no recurrence in the others.

CONCLUSIONEarly biopsy and extensive excision of the scrotal lesion is the first choice of treatment for Paget's disease, with good operative effect and satisfactory prognosis. A 2nd operation could be considered for patients of local relapse.

OBJECTIVETo explore the clinical manifestation, management, recurrence factors and prognosis of scrotal Paget's disease.

METHODSWe retrospectively analyzed the clinical and pathological data of 23 cases of scrotal Paget's disease diagnosed and treated in our hospital from 1996 to 2008.

RESULTSThe disease was confined to one side of the scrotum in 15, and involved the whole scrotum and penis in 8 of the cases. Three patients showed enlarged inguinal lymph nodes in the same side, and 2 in both sides. All the cases were confirmed by biopsy and treated by surgery. Post-operative follow-up was conducted for 2-68 months, which revealed 5 cases of local recurrence and 1 case of death for systemic metastasis.

CONCLUSIONBiopsy is proved to be important for the early diagnosis of scrotal Paget's disease, and extended excision of local lesion is a preferred management.

Objective: To investigate the clinicopathological characteristics, diagnosis, and treatment of primary seminal vesicle adenocarcinoma (SVAC). METHODS: We analyzed the clinical data and clinicopathological characteristics of 4 cases of primary SVAC treated in the Department of Urology of the Second Hospital of Tianjin Medical University and reviewed relevant literature. RESULTS: All the 4 patients were treated by open radical resection of the seminal vesicle and prostate and pathologically diagnosed with SVAC. Preoperative prostatic biopsy had shown 1 of the cases to be negative, while preoperative CT and transrectal ultrasound had revealed a huge pelvic cystic neoplasm in another patient. Immunohistochemistry manifested that the 4 cases were all negative for prostate-specific antigen (PSA), prostatic acid phosphatase (PAP), and cytokeratin 20 (CK20), but positive for cancer antigen 125 (CA125) and CK7. All the patients recovered smoothly after surgery and experienced no recurrence or metastasis during 154, 41, 20, and 12 months of follow-up. CONCLUSIONS Primary seminal vesicle carcinoma is extremely rare and presents in an advanced stage. Immunohistochemistry plays a valuable role in its differential diagnosis. Various combinations of radical surgery, radiotherapy, androgen-deprivation therapy, and chemotherapy are recommended for the treatment of the disease.

OBJECTIVETo study the clinicopathologic features and histogenesis of calcifying fibrous tumor (CFT).

METHODSThe clinical manifestations, histopathologic characteristics and immunophenotype were analyzed in 11 cases of CFT.

RESULTSThe male-to-female ratio was 5:6, with a mean age of 38 years and age range of 25 to 52 years. The sites of involvement included abdominopelvic cavity (n=6), soft tissue (n=4) and scrotum (n=1). Most patients presented with a gradually enlarging and painless mass. Nearly half of the cases were associated with other diseases or history of inflammation, trauma or surgical intervention. One third of the tumors represented incidental findings and showed no recurrence after resection. Imaging revealed a solitary solid soft tissue mass or multiple nodules with clear borders and associated high-density calcifications. Macroscopically, the tumors were well-circumscribed but non-encapsulated. They ranged from 0.5 to 20.0 cm in diameter and were tan-greyish, round to oval, lobulated or irregular and solid with rubbery consistency. The cut surface was whitish to tan-yellowish, gritty and showed scattered spotty yellowish discoloration corresponding to the foci of dystrophic calcifications. Histologically, CFT was composed of hyalinized fibrous tissue and thickened vessel walls with interspersed bland spindly fibroblastic cells, scattered psammomatous calcifications, dystrophic calcification and lymphoplasmacytic infiltration. In addition, focal cloak-like polymorph infiltration at the tumor periphery and entrapment of adipocytes and nerves were demonstrated in some cases. Foci resembling solitary fibrous tumor, fibromatosis, keloid or inflammatory myofibroblastic tumor were observed. Immunohistochemical study showed that the tumor cells were diffusely positive for vimentin and focally positive for CD34, factor VIII-related antigen and beta-catenin. The admixed plasma cells were notably IgG positive, with more than 50% being IgG4 positive.

CONCLUSIONSCFT has characteristic histopathologic manifestations and shows morphologic and immunohistochemical overlaps with known IgG4-related sclerosing diseases. It is possible that CFT may represent another example of IgG4-related diseases. It often runs a benign clinical course, with rare recurrence after surgical resection. Previous inflammation and trauma may be the precipitating factors of CFT.
