Female Urethral Malignant Melanoma With Vesical Invasion: A Case Report

We report a 75-year-old female with a primary urethral malignant melanoma. A mass protruding from inside the urethra was detected on physical examination. Abdominopelvic magnetic resonance imaging revealed a mass extending from the urethra with dimensions of 4 × 2 cm, and periurethral heterogenous fatty planes consistent with infiltration. The histopathologic examination was consistent with HMB45(+) malignant melanoma. We performed cystourethrectomy and bilateral inguinal and pelvic lymphadenectomy in one session. The pathology report revealed primary malignant melanoma of the urethra invading the inferior bladder wall. The patient received no adjuvant therapy because of cardiopulmonary morbidities and the presence of multiple pulmonary metastases. The patient eventually died 13 months after surgery

A Rare Renal Epithelial Tumor: Mucinous Cystadenocarcinoma Case Report and Review of the Literature

Primary renal mucinous cystadenocarcinoma is a very rare lesion of kidney which originates from the metaplasia of the renal pelvic uroepithelium. Only one case with primary mucinous cystadenocarcinoma has been reported in the English literature. We report second case of mucinous cystadenocarcinoma which was radiologically classified as type-IIF Bosniak cyst in peripheral localization. We aimed to present this extreme and unusual entity with its radiological, surgical, and pathologic aspects under the light of literature

Clinicopathological characteristics and treatment outcomes of adult patients with paratesticular rhabdomyosarcoma (PRMS): A 10-year single-centre experience

Introduction: We report our experience with 8 consecutive adults treated for paratesticular rhabdomyosarcoma (RMS) at a single institution between 2000 and 2010

The pathological upgrading after radical prostatectomy in low-risk prostate cancer patients who are eligible for active surveillance: How safe is it to depend on bioptic pathology?

Background Active surveillance (AS) is one of the treatment alternatives in low-risk prostate cancer (PCa). The pathological upgrading after radical prostatectomy (RP) were investigated in patients who were eligible for AS in the present study. Methods Between August 2006 and July 2017, 627 patients underwent RP in our institution. One hundred and thirty-six patients who were eligible for AS at the time of RP were included in this study. The previously defined AS criteria Gleason 3 + 3=6 adenocarcinoma at maximum two biopsy cores, prostate-specific antigen (PSA) < 10 ng/mL and clinical T stage <= 2a were used in the study. The demographics, clinical, and histopathological outcomes were retrospectively compared between two groups, which were divided in accordance with the upgrading status at final pathology as Group 1 (n = 67, upgrading) and Group 2 (n = 69, nonupgrading). Results Gleason upgrading (GU) was found in 67 (49.3%) patients, and 17 patients (12.5%) were upstaged to pT3a. The upgrading to Gleason 3 + 4 was reported in 38.7% of patients, however, 7.4%, and 3.7% of the patients were upgraded to Gleason 4 + 3, and Gleason 4 + 4, respectively. The 10.3% of the patients had extraprostatic involvement, and the rate (19.4% vs 1.4%, P = .002) was significantly higher in Group 1. PSA density (P = .001), tumor size (P < .001), tumor percentage (P < .001), apical involvement (P = .013), and perineural invasion (P < .001) in RP specimen were higher in Group 1. Multivariate analysis showed that perineural invasion (OR = 4.26; 95%CI: 1.76-10.33; P = .001) and pathologic T stage (OR = 5.45; 95%CI: 1.08-27.4; P = .04) were independently associated with GU. Conclusions Since 12.5% of the patients upstaged to pT3a disease, and there is a possible risk of Gleason 4 pattern, upgrading of the tumor should carefully be kept in mind before offering AS to low-risk patients with PCa

A Rare Neonatal Testicular Tumor: Juvenile Granulosa Cell Tumor of Infant Testis: A Report of 3 Cases

Juvenil granulosa, the cell tumor of testis are very rarely seen in children. Radical orchiectomy is sufficient for treatment. In this study, we presented 3 infants with juvenil granulosa cell tumor in testis

The relationship between the expression of E-cadherin and tumor recurrence and progression in high-grade stage T1 bladder urothelial carcinoma

Objective To evaluate the relationship between the expression of E-cadherin (E-CD) and tumor recurrence and progression in patients with high-grade stage T1 urothelial carcinoma of bladder
