Hard bilateral syphilitic testes with vasculitis: a case report and literature review.

BACKGROUND: We report the case of a patient with syphilitic testicular gumma and vasculitis with adrenal failure due to chronic steroid use. CASE PRESENTATION: A 63-year-old male presented with hard right eye swelling and very firm bilateral testes on palpation, which he had for 2 years. Testicular tumor markers were negative; syphilis test was positive. Radiological examination suggested aortitis and bilateral testicular malignancy. The patient received ampicillin for the infection and prednisolone for vasculitis. Left orchidectomy was performed to confirm the presence of testicular tumor; histological examinations revealed granulomatous orchitis. The prednisolone doses were adjusted because of relapses and adverse effects of steroid use. Unfortunately, the patient died in the intensive care unit because of uncontrolled blood pressure and pneumonia. CONCLUSIONS: This is a rare case of syphilis with testicular involvement and vasculitis. This report shows the importance of broadening the differential diagnoses of testicular firmness.

Neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios alone or combined with prostate-specific antigen for the diagnosis of prostate cancer and clinically significant prostate cancer.

Objective: We evaluated whether the blood parameters before prostate biopsy can diagnose prostate cancer (PCa) and clinically significant PCa (Gleason score [GS] ≥7) in our hospital. Methods: This study included patients with increased prostate-specific antigen (PSA) up to 20 ng/mL. The associations of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) alone or with PSA with PCa and clinically significant PCa were analyzed. Results: We included 365 patients, of whom 52.9% (193) had PCa including 66.8% (129) with GS of ≥7. PSA density (PSAD) and PSA had better the area under the curve (AUC) of 0.722 and 0.585, respectively with p=0.001 for detecting PCa compared with other blood parameters. PSA combined with PLR (PsPLR) and PSA with NLR (PsNLR) had better AUC of 0.608 and 0.610, respectively with p<0.05, for diagnosing GS≥7 population, compared with PSA, free/total PSA, NLR, PLR, and PsNPLR (PSA combined with NLR and PLR). NLR and PLR did not predict PCa on multivariate analysis. For GS≥7 cancer detection, in the multivariate analysis, separate models with PSA and NLR (Model 1: PsNLR+baseline parameters) or PSA and PLR (Moder 2: PsPLR+baseline parameters) were made. Baseline parameters comprised age, digital rectal exam-positive lesions, PSA density, free/total PSA, and magnetic resonance imaging. Model 2 containing PsPLR was statistically significant (odds ratio: 2.862, 95% confidence interval: 1.174-6.975, p=0.021) in finding aggressive PCa. The predictive accuracy of Model 2 was increased (AUC: 0.734, p<0.001) than that when only baseline parameters were used (AUC: 0.693, p<0.001). Conclusion: NLR or PLR, either alone or combined with PSA, did not detect PCa. However, the combined use of PSA with PLR could find the differences between clinically significant and insignificant PCa in our retrospective study limited by the small number of samples.

Surgical challenges of Castleman's disease of the pelvis.

Castleman's disease (CD) is a unique lymphoproliferative disorder. It commonly occurs in the mediastinum, neck, axilla, and abdomen, and retroperitoneal involvement is rare. Here we report a unique case of CD in the pelvis. Laparotomy was performed and surgery was complicated by adhesions and vascularity. Total surgical duration was Five hours and 45 min with 4.5 L of blood loss. Ten pints of blood was transfused. The mass was histopathologically diagnosed as hyaline-vascular CD. The patient was free of recurrence after 10 years of follow-up.

Lung adenocarcinoma diagnosed incidentally after renal biopsy for suspected right renal cancer.

We present a case of lung adenocarcinoma metastasizing to the right clear cell renal cell carcinoma diagnosed by computed tomography (CT)-guided renal biopsy and immunohistochemistry. A 72-year-old male patient had right lower abdominal pain for 3 days, followed by right loin pain for 10 days. On CT scan, renal cell cancer was suspected with multiple metastases. Renal cell cancer with metastatic lung adenocarcinoma was diagnosed on CT-guided renal biopsy with positive immunohistochemical markers. The patient, unfortunately, expired after few days of diagnosis. Tumor-to-tumor metastasis is an unusual disease, and its tumors are aggressive. A definite diagnosis of tumor-to-tumor metastasis is a clinical challenge. Immunohistochemistry helped us in the diagnosis without the primary lesion biopsy.

MRI-guided conservative management of a left segmental testicular infarction.

Segmental testicular infarction is a rare condition. Patients present with clinical features similar to torsion and testicular tumors, with most undergoing surgery. A 55-year-old male patient presented with left scrotal pain. We did a Doppler ultrasonogram and magnetic resonance imaging to diagnose his condition and rule out testicular torsion and tumor. We decided not to operate and asked the patient for follow-up. There was no pain in the left testis, and magnetic resonance imaging showed a reduction in the left testicular lesion after 4 months.

Prostate cancer detection rate and Gleason score in relation to prostate volume as assessed by magnetic resonance imaging cognitive biopsy and standard biopsy.

OBJECTIVE: This study aimed to assess the relationship of the prostate cancer and Gleason scores (GSs) or ISUP Grade system with prostate volume (PV) as assessed by magnetic resonance imaging (MRI) cognitive biopsy and standard biopsy. MATERIAL AND METHODS: Data were collected from 659 patients who underwent MRI cognitive biopsy and standard biopsy from January 2014 to January 2018. The biopsies were performed because of increased prostate-specific antigen (PSA) levels (>4 ng/mL) and/or abnormal digital rectal examination findings. Transrectal ultrasound was used to measure PV. RESULTS: Prostate cancer detection rates in patients with increased PVs of ≤40 cc and >40 cc were 68.8% and 51.6% (p<0.001), respectively. ISUP Grade group ≥2 (Gleason score ≥3+4) detection rates for increased PVs of ≤40 cc and >40 cc were 68% and 73%, and 22.3% and 37.8%, respectively, for those with ISUP Grade group ≥4 (Gleason score ≥8) (p=0.003). Among the patients with PV>40 cc, univariate logistic regression showed a significant relationship between ISUP Grade group ≥2 and PSA, free/total PSA, PSA density, and MRI (p<0.05). On multivariable logistic regression, MRI (p=0.014) and PSA (p=0.039) predicted ISUP Grade group ≥2 in patients with PV>40 cc. CONCLUSION: Although the detection rates of prostate cancer decreased as PV increased, the detection of prostate cancer aggressiveness increased as PV increased. This increase in high ISUP Grade lesions with the rise in PV is due to the use of MRI during prostate biopsy with standard biopsy.
