Hydronéphrose géante sur urétérocèle compliquée de lithiase urétérale

L'hydronéphrose géante est définie comme une importante dilatation des cavités pyélo-calicielles occupant une grande partie de la cavité abdominale, ou une dilatation contenant plus d'un litre d'urine débordant la ligne médiane. Elle est dûe le plus souvent à un syndrome de la jonction pyélo-urétérale. L'obstruction par urétérocèle compliquée de lithiase est une cause très rare. Nous rapportons le cas d'un patient de 45 ans, ayant comme antécédent des douleurs lombaires droites non explorées, qui a consulté pour une masse abdominale évoluant depuis quelques années associée à une constipation intermittente. L'examen clinique a objectivé une distension abdominale asymétrique avec une matité débordant la ligne médiane. L'échographie a montré une formation liquidienne multi-cloisonnée occupant toute la région abdomino-pelvienne droite et refoulant les structures digestives. L'uroscanner a dévoilé une énorme dilatation urétéro-pyélo-calicielle droite (pyelon mesurant 15,2cm) laminant complètement le parenchyme rénal avec absence d'excrétion du produit de contraste, en amont d'une urétérocèle compliquée d'un calcul de 2cm. Une néphro-urétérectomie a été réalisée par laparotomie et les suites post opératoires ont été simples

Primary Malignant Melanoma of the Urinary Bladder

Introduction. Primary melanoma of the urinary bladder is very rare. As far as we know, 19 cases have been reported worldwide, usually as case reports. Case Presentation. We present a 71-year-old male patient presented with a 2-month history of hematuria. Ultrasonography revealed a 5-cm-size mass located in the bladder trigone. A transurethral resection of the bladder tumor (TURBT) revealed a malignant melanoma. Evaluation for metastatic disease was negative. The patient deceased five months later before radical treatment could be performed. Conclusion. This is one more reported case of primary melanoma of the urinary bladder. The previously reported cases of bladder melanoma are reviewed. Therapy and prognosis are discussed

Spectacularly Successful Microsurgical Penile Replantation in an Assaulted Patient: One Case Report

Penile amputation is a rare condition for which immediate surgical replantation is warranted. We present herein one case of a 27-year-old male who presented to the Emergency Department after his wife cut his penis. The penis was replanted microsurgically. The deep dorsal penile veins and superficial veins were anastomosed. Although we could not reanastomose the arteries, wound healing occurred without any problem one week postoperatively and the patient regained erectile function 4 weeks after surgery. At 1-year follow-up examinations he reported on restored erectile function and a normal urinary function

Conservative Management of a Congenital Seminal Vesicle Cyst Associated with Ipsilateral Renal Agenesis Revealed by Cystitis: One Case Report

Seminal vesicle cyst is an extremely rare disease. Its association with ipsilateral renal agenesis is even more exceptional. We present herein one case of a 16-year-old male who presented with a four-month history of lower urinary tract symptoms (LUTSs) and micturition pain. The digital rectal examination revealed a small mass arising from the prostate. The urine culture showed that E. coli is sensitive to all antibiotics tested. Transrectal ultrasound (TRUS) revealed a cystic mass in the outer prostate. Seminal vesicle cyst and left renal agenesis were confirmed by magnetic resonance imaging (MRI). Maximum flow (Qmax) at uroflow was greater than 15 mL/sec. We therefore decided to manage this disease conservatively with alpha blockers and antibiotics. After 6-month' followup the patient did not report any complain and the uroflow test was similar to a normal urination. From one case report and literature review, the authors suggest a diagnostic and therapeutic strategy for the management of this rare condition

Isolated localization of Rosai Dorfman disease as renal mass: a case report and review of literature

We report a rare case of an elderly woman presented with right renal mass with invasion of renal vein and several small lymphadenopathy in the hilar area .the diagnosis of kidney cancer is suspected and the patient underwent open radical nephrectomy, surrenalectomy and lymphadenectomy dissection. The pathologic examinations find a rosai dorfman disease. This unusual benign entity is uncommon in the kidney, but in medical imaging, it may simulate an infiltrative renal neoplasm, especially a lymphoma or leukemia or even renal cell carcinoma. A comprehensive literature review was undertaken to summarize the clinical and pathologic features of this disorder.Pan African Medical Journal 2016; 2

Anaplasic lymphoma kinase positive inflammatory myofibroblastic tumour with renal pelvic calculus: a case report

Inflammatory myofibroblastic tumour is a distinctive mesenchymal neoplasm, composed of a variable admixture of myofibroblastic spindle-shaped and inflammatory cells which were originally described in the lung, as a nonneoplastic lesion and designated as an inflammatory pseudotumour. The lack of certainty of the IMTs pathogenesis is reflected in the large number of terms which have been attributed to this lesion. Recent genetic and molecular studies of IMTs have showed chromosomal abnormalities of 2p23 resulting in a rearrangement of the anaplasic lymphoma kinase gene and have also provided evidence for a monoclonal, noeplastic origin for IMT.Occurrence of IMT in the kidney is very rare, and to our knowledge, only 30 such cases have been described in the literature.This report describes an original case of an ALK positive IMT of the kidney associated with renal pelvic calculus which we believe has never been reported. The differential diagnosis of IMTs will also be discussed

Epididymal Leiomyosarcoma: One Case Report

Epididymal leiomyosarcoma is very uncommon. Only 16 cases have been reported in the literature. There has never been a reported case of a patient with an African origin with this tumor. We report the medical history of a 70-year-old man who presented an enormous mass located in his epididymis. A tricut biopsy was performed which allowed histological confirmation of epididymal leiomyosarcoma after which the patient underwent excision of the mass. The patient died after the first round of chemotherapy

Pheochromocytoma of the urinary bladder: a case report

Urinary bladder pheochromocytoma is rare. From a case report of unsuspected pheochromocytoma and literature review, the authors develop a diagnostic and therapeutic algorithm for the management of this ectopic pheochromocytoma localization

Para testicular rhabdomyosarcoma in adults: three case reports and review of literature

Paratesticular embryonal rhabdomyosarcoma (RMS) is a rare tumor arising from the mesenchymal tissues of the spermatic cord, epididymis, testis and testicular tunics. We report three cases of adult paratesticular RMS, two embryonic and one pleomorphic rhabdomyosarcoma. All the patients underwent diagnostic orchidectomy. The work up investigations revealed lung metastases. Chemotherapy with Ifosfamide and Doxorubicin was used in two cases, whereas Vincristin- Actinomycin D and Cyclophosphamide was received in one case. An objective partial response was reported in 2 cases, with complete response in one case. Paratesticular RMS is a rare and aggressive tumor. Because of the absence of protocols designed specifically for adult patients, it is necessary to follow therapeutic guidelines in pediatric protocols

Renal hilar pheochromocytoma: a case report

Paraganglioma is a rare tumor arising from undifferentiated cells of the primitive neural crest. These tumors are most commonly found in the adrenal gland, other localisations are also possible. A 58-year-old woman who presented with history of left lumbar pain, headache, hypertension, palpitation and sweating was found to have a secreting left renal hilar pheochromocytoma. Radical excision of the tumor was therefore undertaken and her hypertension was controlled. From the case report and literature review, the authors suggest a diagnostic and therapeutic strategy for the management of ectopic localization of pheochromocytoma
