[Bellini duct carcinoma: a new case study and literature review]. / Carcinome du tube collecteur de Bellini: une nouvelle observation avec revue de la littérature.

Bellini duct carcinoma is a very rare type of renal cell carcinoma (RCC), accounting for less than 1%. It arises from the distal nephron, more specifically from the collecting duct. Its morphological features are extremely variable, making its diagnosis difficult. We report the case of a 62-year old patient admitted with a painless progressive left flank swelling. CT scan showed a huge mass occupying the upper portion of the left kidney. The patient underwent radical nephrectomy. Anatomopathological examination showed collecting duct carcinoma of the kidney. Patient's evolution was exceptionally favorable: no recurrence, no locoregional metastasis and no distant metastasis.

Large prostatic stones with staghorn renal calculus in a 61-year-old man: an unusual presentation of uncommon disease.

Prostatic parenchymal calculi are common in ageing men who are evaluated for benign prostatic hyperplasia or prostate cancer. Giant prostatic calculi are very rare, usually associated with local predisposing factors for urinary stasis and infections, and traditionally managed by open surgery. We present the first case of its kind to be associated with a concurrent staghorn nephrolithiasis, and removed successfully by endoscopic approach using an access sheath through the urethra.

Upper urinary tract lipoma: A case report.

Upper urinary tract (UUT) benign tumours are rare. We present a case of UUT lipoma in a 41-year-old man with left flank pain. A computed tomographic urography scan revealed an irregular thickening of the left renal collecting system wall extending from the upper calices to the renal pelvis. The diagnosis of UUT was made and the patient underwent a nephroureterectomy with bladder cuff excision, as standard treatment. However, macroscopic and histological examination revealed a lipomatous tumour with no sign of malignancy. To our knowledge this is the first reported case of its kind of a UUT managed first with a minimally invasive approach.

Paratesticular adenofibroma.

Paratesticular adenofibroma is an uncommon benign tumour. Although it has previously been reported in the female reproductive organs, to our knowledge only three cases have previously been reported in the male genital organs. Herein we describe an adenofibroma that developed in the tunica vaginalis and rete testis. We discuss its histogenesis and conservative treatment.

Multiple myeloma presenting as bilateral renal complex stones.

Hypercalcaemia is a frequent complication of multiple myeloma. A mild degree of nephrocalcinosis has been noted in occasional patients and renal calculi are also sometimes present. We report herein a case of multiple myeloma that was revealed by the presence of bilateral calcium renal staghorn calculi. Medical treatment of myeloma, surgical management of this complex lithiasis and the course of multiple myeloma are discussed.
