Signet Ring Cell Carcinoma of the Vater's Ampulla: A Very Rare Malignancy.

Most tumors affecting Vater's ampulla are adenocarcinomas, and other histological variants are less frequent. Signet ring cell carcinoma is more commonly found in the stomach than at other sites of the digestive system. Signet ring cell carcinoma of the Vater's ampulla is extremely rare, and only 15 cases have previously been described in the literature.

[Eosinophilic angiocentric fibrosis: a form of IgG4-related systemic disease?].

Eosinophilic angiocentric fibrosis is a rare fibro-inflammatory disorder of unknown etiology with only 40 cases reported in the literature. It primarily affects the sinonasal tract and more rarely the orbit, the larynx and the gums. This benign disorder is characterized by a slowly progressive process mimicking a tumor, with frequent recurrences after surgical excision and cortico-therapy.

Solitary granular cell tumor of cecum: a case report.

Granular cell tumor (GCT) was first described by Abrikossof in 1926. This tumor is a benign neoplasm of unclear histogenesis that is generally believed to be of nerve sheath origin. GCT is not common and most often affects the tongue, skin, and soft tissue, although it may occur anywhere in the body.

Low-grade fibromyxoid sarcoma arising in the big toe.

Low-grade fibromyxoid sarcoma (LGFMS) is a rare neoplasm commonly affecting young adults and typically arising in the somatic soft tissue of the proximal extremities. Its occurrence within the big toe is exceedingly rare. A 43-year-old man had surgery on a mass located in the big toe, which was first noted 6 months previously.

Primary malignant melanoma of prostate.

Primary genitourinary melanoma accounts for less than one per cent of all cases of melanoma. Most cases attributed to the prostate actually originate from the prostatic urethra. Due to its infrequency, primary malignant melanoma of the genitourinary tract presents a difficult diagnostic and management challenge.

Primary leiomyosarcoma of the male urethra: a case report.

Background: Cancers of the male urethra constitute less than 1% of all malignant urological tumours, and the occurrence of sarcomas in the urethra is even less frequent. To our knowledge, only one case has been previously described in the English literature.

Case Presentation: We report the clinical features, histology, imaging and treatment of urethral leiomyosarcoma in a male patient.

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.

Intracystic papillary carcinoma associated with ductal carcinoma in situ in a male breast: a case report.

Introduction: Intracystic papillary carcinoma represents a small distinctive subgroup of noninvasive breast cancer, accounts for <0.5% of breast malignancies and is extremely rare in men, it was originally reported as a localized non-invasive carcinoma, but is usually associated with ductal carcinoma in situ around the main tumor or invasive carcinoma.

Case Presentation: We report a case of 50-year-old man with intracystic papillary carcinoma in man with ductal carcinoma in situ who underwent a tumorectomy following by a radical Patey intervention (Halsted).

[Congenital male urethral diverticulum].

The male urethral diverticulum is a rare affection. The authors report one case of congenital urethral diverticulum. The diagnosis was approved by clinical examination and urethrocystography.

[Renoduodenal fistula. A case report].

The fistula between kidney and duodenum is rare. It occurs mostly in case of pyonephrotic kidney. The authors report one case of renoduodenal fistula, discovered peroperatively in 41 years old man who underwent a subcapsular nephrectomy for right pyonephrosis upon pelvic lithiasis.

[Retroperitoneal fibrosis with pelvic extension: a case report].

The retroperitoneal fibrosis is a rare pathology, whose physiopathologic mechanism is poorly known. It characterizes by the training of a benign fibrous prevertebral plate. This plate is in rule limited between the renal pedicle in high and the promontory anointed down.

[Percutaneous nephrostomy in emergencies. Report of 42 cases].

Purpose: Through this work we are going to demonstrate the interest and the contribution of the percutaneous nephrostomy in obstructive anuria and in pyonephrosis.

Patients And Methods: It is a retrospective study concerning 42 cases. The average age of the patients is 50 years (19-80 years).

[Renal leiomyoma. Case report].

The authors report a case of renal leiomyoma observed in a 56-year-old man. This cyst presented in the from of loin pain. Computed tomography revealed a homogeneous renal tumor.
