Solitary fibrous tumor (SFT) of the prostate is a very rare tumor. We report a case of 65-year-old man with SFT of the prostate which was initially misdiagnosed as prostate cancer. Finally, we performed total prostatectomy and the tumor was histologically diagnosed as SFT of the prostate. The patient's clinical course has progressed favorably with no obvious recurrence 18 months postoperatively.

Introduction. The three types of priapism are stuttering, arterial (high-flow, nonischemic), and venoocclusive (low-flow, ischemic). These are usually distinct entities and rarely occur in the same patient. T-shunts and other distal shunts are frequently combined with tunneling, but a seldom recognized potential complication is conversion to a high-flow state. Case Presentation. We describe 2 cases of men who presented with low-flow priapism episodes that were treated using T-shunts with tunneling that resulted with both men having recurrent erections shortly after surgery that were found to be consistent with high-flow states...

A 48-year-old man admitted to the urology outpatient clinic with major symptoms of right-side pain and intermittent lower urinary tract symptoms (LUTSs) such as low urine flow rate, dysuria, and frequency. Uroflowmetry showed low urine flow, and laboratory tests revealed no pathology. Ultrasound (US) showed a 7 cm calcific mass above the bladder and a kidney cyst with a diameter of 5.3 cm in the upper pole of the right kidney. Enhanced computed tomography confirmed the US findings. Laparoscopic transperitoneal renal cyst decortication was performed...

An 84-year-old woman was referred to our department due to gross hematuria. Enhanced computed tomography revealed early enhancement of the right renal vein and multiple tortuous vessels around the right renal hilus, part of which had invaded into the renal parenchyma and renal calix. We diagnosed her with arteriovenous malformations (AVMs) and performed transcatheter arterial embolization (TAE). Angiography showed extensive and complex AVMs located in the central and peripheral areas of her kidney. After TAE, the hematuria resolved and she became hemodynamically stable...

Background. Intravesicular Bacillus Calmette-Guérin (BCG) is an effective adjunctive therapy for superficial bladder cancer that has been shown to delay recurrence and progression of disease. Serious side effects are relatively rare but are difficult to diagnosis and commonly overlooked. Case Presentation. We report the case of a patient who was found to have mycotic aortic aneurysms secondary to treatment with BCG after a prolonged course with multiple intervening hospitalizations. Conclusion. Through this report, we discuss our present understanding of BCG infection following treatment and review the literature regarding this particular rare manifestation...

Background. Prostate cancer is the most common cancer diagnosed in men. As new focal therapies become more popular in treatment of prostate cancer, failure cases requiring salvage therapy with either surgical or other techniques are being reported. Objective. To report the options in treatment of prostate cancer after recurrence or failure of the primary treatment modality. Methods. We report a salvage robotic assisted laparoscopic radical prostatectomy (RALP) for prostate cancer recurrence following high intensity focused ultrasound treatment (HIFU) in the United States...

Presacral myelolipomas are rare, benign, asymptomatic tumors composed of mature adipose tissue and hematopoietic elements, but fewer than 50 cases have been reported in the literature. They are usually discovered incidentally during imaging studies and are often misdiagnosed as liposarcoma, which have a malignant nature, because the imaging findings of myelolipoma can be similar to those of liposarcoma. It is challenging to distinguish presacral myelolipomas from other presacral fat-containing tumors without performing a histological examination...

We present an uncommon case of mucinous adenocarcinoma of the bladder (MAB) with signet-ring cells extensively infiltrating prostate gland and pelvic/retroperitoneal lymph node stations and not responsive to usual systemic chemotherapy regimens. This case highlights the important features of MAB including the pattern of tumor spread, the tendency for initial misdiagnosis, and the importance of immunohistochemical study in order to define its primary origin from the bladder and choose the most appropriate treatment since the beginning...

The incidence of Multilocular cystic renal cell carcinoma (MCRCC) in literature is very low and confounding MCRCC with cystic nephroma (CN) is even more unusual. The aim of this report is to present a case of MCRCC and emphasize the importance of the preoperative radiologic evaluation and immunohistochemical staining confirmation to obtain an accurate diagnosis. A 73-year-old woman presented with a history of 4-month right flank pain. CT showed a Bosniak type III renal mass. After laparoscopic partial nephrectomy the initial report was cystic nephroma...

Introduction. Angiomyolipomas are the most common benign tumor of the kidney, associated with Tuberous Sclerosis in 20% of cases and arising sporadically in 80% of cases. Renal angiomyolipomas are neoplasms of mesenchymal origin with varying proportions of vasculature, smooth muscle spindle cells, and adipocytes, making management of such neoplasms a challenging endeavor. Possible management options include partial or radical nephrectomy and segmental renal artery embolization. Case Presentation. A 61-year-old woman admitted for a large retroperitoneal hemorrhage was discovered to have a giant, sporadic, 3818...

Two cases of inflammatory myofibroblastic tumor (IMT) of the bladder are reported here. Both patients were male and presented with macroscopic hematuria; in the first case terminal hematuria was associated with irritative voiding symptoms. The second case was a smoker with hematuria unresponsive to medical treatment and anemia. Clinical presentation, pathological features, treatment, and prognosis are discussed. Due to rarity of this pathological condition, there are no guidelines concerning treatment and follow-up...

Condyloma acuminata in the external genitalia (genital warts) is a sexually transmitted disease that is often caused by human papillomavirus (HPV). We report a case of giant genital condyloma acuminata in a 35-year-old male patient with HIV comorbidity treated by wide surgical excision. Excision defect was covered with split thickness skin graft (STSG) and double keystone flaps. There was no complication after surgery. Ten months following surgery, there was no new condyloma lesion and the patient had normal voiding and erectile functions...

Context. An inguinoscrotal swelling occurring during an acute pancreatitis is very rare. Case Report. We report a case of right inguinoscrotal swelling appearing in connection with an interstitial edematous acute pancreatitis. We have noticed a spontaneous complete reduction of the right inguinoscrotal swelling after 10 days. Conclusion. The management of a scrotal swelling should be the least invasive possible method but also the most complete possible method to avoid unnecessary interventions. The exclusion of a pathology that could affect the vital prognosis of the testis remains the absolute priority...

A mid-aged male presented with progressive lower urinary tract symptoms (LUTS) for years. Huge prostate with low serum prostate-specific antigen (PSA) level was detected. The specimen from transurethral resection revealed surprising pathology finding as malignant peripheral nerve sheath tumor (MPNST). Considering its huge size (more than 300 gm) and location, we prescribed neoadjuvant chemotherapy firstly. The tumor became regressive and then radical surgical resection was achieved. Adjuvant multimodality treatment including concurrent chemoradiotherapy (CCRT) and target therapy was given...

Although midurethral mesh tape slings are considered the standard of care in the treatment of female stress urinary incontinence (SUI), complications such as pain, dyspareunia, or erosion are known to occur in addition to persistent incontinence. The management of these types of mesh sling complications can be very complex, especially when the pain is not just isolated to the vagina but extends into other areas, such as the abdomen which requires a much more extensive dissection. Additionally, if a mesh sling needs to be removed, the patient will most likely have a return of her SUI that often necessitates subsequent treatment...

Malignant Peripheral Nerve Sheath Tumors (MPNSTs) of the prostate are extremely rare. A very unusual case of simultaneous adenocarcinoma and MPNST of the prostate is reported. A 60-year-old Caucasian male presented for annual urologic examination. Digital rectal examination revealed a painless, toughish, and asymmetrically enlarged prostate. Serum prostate-specific antigen was 1 ng/mL. Radiologic examinations demonstrated a large mass, which was arising from the left peripheral lobe of the prostate. The patient underwent transrectal ultrasound-guided biopsy of the prostate which revealed a smooth muscle tumor of uncertain malignant potential...

Acute gastroenteritis with viral infection in infants causes severe diarrhea and often results in acute renal failure due to severe dehydration. However, a viral infection, particularly rotavirus, rarely induces postrenal failure due to bilateral stones in infants. Herein, we report three cases of postrenal failure in infants due to bilateral ureteral stones induced by acute gastroenteritis with rotavirus. Following immediately nephrostomy, chemical dissolution therapy succeeded to treat postrenal failure. Immediate nephrostomy for the release of upper urinary tract obstruction combined with urinary alkalization as a chemical dissolution therapy should be considered in such cases...

We report a 32-year-old female case of a right adrenal gland mass detected on CT scan at medical checkup. CT and MRI showed a mass of 5.1 cm made of fat and calcification in the right adrenal gland, leading to the clinical diagnosis of adrenal myelolipoma. Because of its relatively large size and the patient's desire, the patient underwent gasless single-port retroperitoneoscopic adrenalectomy using the RoboSurgeon system. Histopathological examination revealed that the cystic tumor is composed of keratinized epidermis, mature fat, nerve, cartilage, bone, and sebaceous glands compressing the normal adrenal gland, leading to the diagnosis of retroperitoneal mature cystic teratoma...

Advances in the treatment of melanoma are resulting in patients living for extended periods after being diagnosed with metastatic disease. Metastases to the ureter are rare, but they have been described in the literature on a number of occasions. In this case report, we describe a patient with established metastatic melanoma who, whilst taking and responding to immunomodulatory therapy, was found to have an obstructive mass in the middle of his left ureter. Rather than performing either a nephroureterectomy or partial resection of the ureter, we opted to perform an endoscopic resection of the melanoma...
