Late recurrence from a renal cell carcinoma: solitary right maxilar mass 17 years after surgery.

Objectives: To report a new case of late renal cell carcinoma recurrence.

Methods: Renal cell carcinoma represents approximately 3% of all adult malignancies. The most frequent metastatic sites are lung (76%), regional lymph nodes (66%), bone (42%), and liver (41%), and it is the third most common infraclavicular neoplasm to metastasize to head and neck.

Pancreatic and psoas abscesses as a late complication of intravesical administration of bacillus Calmette-Guerin for bladder cancer: a case report and review of the literature.

Introduction: Bacillus Calmette-Guerin (BCG) is a live attenuated strain of Mycobacterium bovis that has been used to treat urothelial carcinoma since 1976, and has been reported to eradicate disease in more than 70% of patients with in situ and stage I disease. To the best of our knowledge, we report the first case of disseminated bacillus Calmette-Guerin infection causing multiple abscesses affecting the pancreatic head and right psoas muscle, diagnosed 5 years after intravesical treatment with bacillus Calmette-Guerin therapy for bladder cancer.

Case Presentation: An 83-year-old Caucasian man was hospitalized with a 2-month history of back pain, anorexia, generalized weakness and a 47-pound weight loss.

[Tolerability and complications of ultrasound guided prostate biopsies with intrarectal lidocaine gel].

Objectives: The objective of our study was to evaluate patient tolerance to transrectal ultrasound guided prostate biopsy using anesthesia with 2 grams of intrarectal lidocaine gel, and to evaluate the complications of the test.

Methods: 148 prostate biopsies with intrarectal lidocaine were performed over a four month period. The same intrarectal ultrasound transducer and needle mechanism were employed for all patients.

[Intravesical therapy: Influence on superficial bladder cancer progression].

Objectives: To review the influence of various intravesical treatments on superficial bladder cancer progression.

Methods: We retrospectively reviewed 473 superficial bladder neoplasias. Based on diagnosis and transurethral resection of bladder tumor (TUR BT), and depending on pathology, we proposed different treatment and follow-up schemes, with BCG in 139 cases and intravesical chemotherapy, mainly Mytomicin C, in 80.

[Giant intertesticular epidermoid cyst].

Objective: To report a rare case of a giant epidermoid cyst in an intertesticular localization, analyzing its histological and pathologic features, and to perform a bibliographic review.

Methods/results: We report the case of a 49-year-old male consulting for a slowly growing intra-scrotal mass of five years of evolution causing discomfort because of its size. After excision the pathology report showed the presence of a keratoid epidermoid cyst very big in size.

[Solitary pararenal fibrous tumor].

Objectives: To report a rare clinical case of solitary pararenal fibrous tumor, analyzing its pathological characteristics and prognosis by a bibliographic review.

Methods/results: We present the case of a 36-year-old male consulting for right flank colic pain, which was diagnosed of a solid mass in the lower pole of the right kidney and underwent right radical nephrectomy. Pathological study of the surgical specimen showed the presence of a solitary pararenal fibrous tumor.

[Neurosyphilis and bladder dysfunction].

Objectives: Syphilis is a systemic disease the course of which follows successive clinical stages. Central nervous system and spinal cord involvement on late phases may lead to bladder dysfunction. We report one case of neurosyphilis with associated bladder hyperreflexia.
