Incidental discovery of a case of renal tuberculoma after intravesical BCG treatment.

Intravesical BCG treatment used in the management of NMIBC, usually presents as side effects: pollakiuria, hematuria, fever. Rarer complications may occur, affecting all organs of the urinary tract. Renal tuberculoma, a rare complication of intravesical BCG treatment, may be asymptomatic. It will be necessary to think about it, in front of the appearance of a tumoral lesion of renal localization post intravesical BCG treatment.

Paediatric cystolitholapaxy using mini PCNL-kit through the Mitrofanoff stoma.

Bladder stones are a common complication after augmentation cystoplasty and urinary diversion. However, the treatment of recurrent cystolithiasis in neuropathic children remains a real challenge for urologists and open procedures may be associated with significant morbidity. Currently, mini-invasive management options are available in the therapeutic armamentarium. Herein, we reported a case of Mitrofanoff cystolitholapaxy using a mini PCNL-kit, in a 14-year-old patient with the history of neurogenic bladder due to myelomeningocele managed by bladder augmentation. This technique has been previously described but we have added a unique modification using Nelaton catheter for carefully dilating the Mitrofanoff stoma before inserting an Amplatz sheeth and we report tips and tricks to guarantee a stone free status with one single procedure. Using high energy Holmium laser, this approach is safe and effective even with large stone burden.

Prostatic rhabdomyosarcoma revealed by acute urinary retention.

Rhabdomyosarcoma of the urinary tract is very rare among young adult and the survival has improved significantly. The challenge of such location is to ensure better functional outcomes like continence and sexuality without compromising the overall survival. Throughout this case, we bring new insights into the conservative management of prostatic sarcoma and we focus on the role of radio-chemotherapy for local disease control.

A case report of prostate cancer presenting as a symptomatic pelvic mass mimicking lymphoma.

INTRODUCTION: Metastatic prostate cancer is a relatively common condition in elderly men. The aim of this paper is to report a rare case of metastatic prostate cancer presenting as a large pelvic mass mimicking lymphoma and to discuss its management. PRESENTATION OF CASE: An 85-year-old patient was complaining of lower urinary tract symptoms, and significant pelvic swelling. On physical examination, a 15-cm pelvic mass and lumpy prostate were found. Laboratory investigations revealed elevated PSA levels (PSA=300g/mL). CT scan showed a large lobulated necrotic pelvic mass and multiple swollen lymphnodes. The diagnosis of an atypical pelvic lymphoma associated with a metastatic prostate cancer was first evoked. An ultrasonography-guided biopsy of the mass was carried. The immunohistochemical study confirmed prostate adenocarcinoma. A bilateral orchiectomy was performed. A follow up of 3 months showed a decrease of PSA without shrinkage of the mass. DISCUSSION: A metastatic prostate cancer presenting as a compressive pelvic mass mimicking other diagnosis such as lymphomas, is a rare circumstance of discovery. In our case, atypical pelvic lymphoma was evoked based on the association of multiple retroperitoneal enlarged lymphnodes. Histological findings of the biopsy rectified the diagnosis and confirmed prostate adenocarcinoma. The main treatment for such metastatic prostate cancers remains hormone therapy. Some authors reported external beam radiotherapy in order to reduce prostate volume. CONCLUSION: Prostate cancer should be considered in the assessment of large pelvic masses. Digital rectal examination and testing PSA levels can lead to the diagnosis. After histological confirmation, the androgen deprivation is the main treatment.

Giant recurrent liposarcoma of the retroperitoneum - A surgical challenge: A case report.

INTRODUCTION: Sarcomas are a rare entity with heterogeneous clinical behavior. We herein present the case of a giant retroperitoneal dedifferentiated liposarcoma and aim to remind the clinical, histological, and therapeutic features of this rare tumor. PRESENTATION OF CASE: An 80-year-old patient was complaining of significant abdominoscrotal swelling. On physical examination, a 25-cm swelling extending from the right iliac fossa to scrotums, was observed. CT scan revealed a retroperitoneal fatty mass with necrotic areas. Ultrasonography-guided biopsy was carried. Pathological report demonstrated a dedifferentiated sarcoma. An en bloc resection of the tumor was performed through a right iliac incision extended to the scrotum. After one year of follow up, the patient had a 30-cm local recurrence. After complete resection, the patient died two days after the procedure due to neurological distress. DISCUSSION: 'Giant' liposarcomas over 20kg are extremely rare. CT-Scan and MRI are very useful for defining their size and limits. The resection of a retroperitoneal sarcoma of remarkable size is a challenge for the surgeon owing to the anatomical site that makes it hard to obtain safe margin and to the adherences with the contiguous organs. Dedifferentiated histologic subtypes and negative surgical margins are associated with poor prognosis. This explains the high rate of local recurrence after surgical excision. CONCLUSION: In rare cases, retroperitoneal dedifferentiated liposarcomas can extend through the inguinal canal to the scrotum. Surgical resection obtaining negative margins, remains the curative treatment that reduces the risk of recurrence. Careful follow-up to detect early recurrence is essential for optimal care.

A Rare Scrotal Tumor: Epididymal Cavernous Hemangioma.

INTRODUCTION: Paratesticular tumors are rarely observed among scrotal neoplasm. Various types of benign lesions are described. Cavernous hemangioma belongs to uncommon epididymal benign tumors. Clinical and sonographic features are not conclusive and diagnosis requires histological confirmation. CASE PRESENTATION: Authors report a case of an epididymal hemangioma in a 56-year-old patient, consulting for a painful scrotal swelling. As malignancy was suspected, he underwent inguinal orchiectomy. Histological examination confirmed the diagnosis of cavernous epididymal hemangioma. Clinical and therapeutic aspects of this rare entity are discussed. CONCLUSION: Epididymis is an infrequent location of cavernous hemangioma. Diagnosis is rarely made preoperatively as symptoms and radiological aspects are not specific. Conservative surgery must be attempted once feasible for aesthetic and functional purposes.
