Palpable testicular masses in men aged 20 to 50 years usually represent testicular germ cell tumors. Diagnostic work-up involves ultrasound examination as well as serum tumor markers alpha fetoprotein, beta-human chorionic gonadotropin and lactate dehydrogenase, and particularly the novel marker M371. Orchidectomy is mandatory for germ cell tumors. We report the rare case of testicular involvement by tertiary syphilis mimicking testicular neoplasms with testis-sparing management. A 46-year-old Caucasian male presented with a painless firm mass in the right testicle and multiple cutaneous plaques at the skin of the scrotum, penis and right forearm. Testicular serum tumor markers were negative. Syphilis Rapid Plasma Reagin test and Treponema pallidum immunoglobulin antibodies tests were positive. Radiological examination revealed bilateral testicular lesions as well as bipulmonal pleural-based opacities. Conservative management was attempted and treatment with ceftriaxone (2 g/day) intravenously for 14 days was administered. The testicular findings improved rapidly and significantly during antibiotic treatment. Radiological follow-up examinations after two weeks and two months showed further regression of the testicular and pulmonary lesions. This case represents an extremely rare testicular manifestation of tertiary syphilis. Due to rising syphilis incidence in Europe, tertiary syphilis with formation of gumma should be a differential diagnosis of testicular tumor. Thus, syphilis-specific treatment is safe and orchidectomy can be avoided.

Introduction and Objectives: Knowledge about the significance of sarcopenia (muscle loss) in prostate cancer (PCa) patients is limited. The aim of this study was to determine the influence of skeletal muscle index (SMI) on early functional and pathological outcome in patients undergoing radical prostatectomy (RP).Materials and Methods: One hundred randomly chosen patients who received RP between November 2016 and April 2017 at Martini-Klinik (Hamburg, Germany) were retrospectively assessed. SMI (skeletal muscle mass cross-sectional area at L3/m2) was measured by preoperative staging computed tomography scans at L3 level. Cox regression analysis was applied to determine the impact of SMI on post-operative outcome. Follow-up was 12 months. Continence was defined as no more than one safety pad per day.Results: Mean age of the cohort was 63.6 years. Mean SMI was 54.06 cm2/m2 (range, 40.65–74.58 cm2/m2). Of the patients, 41.4% had pT2, 28.7% had pT3a, and 29.9% had pT3b or pT4 PCa. SMI revealed to be without significant correlation on tumor stage. Follow-up data of 55 patients were available for early functional outcome analysis. SMI showed no significant influence on erectile function in multivariable Cox regression analysis. In multivariable Cox regression analysis, SMI turned out to have no influence on continence rates 6 weeks after surgery.Conclusion: The present study shows that patients undergoing RP have a wide range of SMI. Unlike in other urological malignancies, there was no significant impact of SMI on early functional outcome and pathological outcome. A larger cohort is needed to confirm these results.

Large-cell calcifying Sertoli cell tumor (LCCST) is a rare, testicular sex cord, gonadal stromal tumor that belongs to the histological subgroup of Sertoli cell tumors. LCCSTs may involve malignant potential. However, metastasis is a rare phenomenon. We describe a case of benign late-onset LCCST with testis-sparing surgery. Modern imaging techniques were useful for considering organ-sparing surgery. The ultrasound of a 37-year-old man disclosed a sharp demarcated and strong hyper-echoic lesion sized 1.5 cm, with broad dorsal acoustic shadowing. Testicular tumor markers, including lactate dehydrogenase (LDH), alpha-fetoprotein (AFP), and Beta-human chorionic gonadotropin (ß-HCG) did not reveal any pathological finding. Contrast-enhanced MRI of the pelvis showed a ring-shaped tumor with a strong contrast medium enhancement. Sections of the tumor showed a hard mass with a white calcified ring. A frozen section examination of the testicular tumor did not indicate malignancy. Histologic examination revealed a prominent and noticeable calcification of approximately 3 mm thickness. Tumor cells presented in the form of solid nests, tubules, and cords. Our present case differs from previously reported LCCST cases because the tumor was unilateral, smaller in size, and presented in an older patient.
