Renal artery stenosis in renal transplantation presentation and management.

A review of the angioplasty records between 1990 and 1995 at the King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia revealed ten cases of transplant renal artery stenosis (RAS). The diagnosis in these cases was confirmed by renal angiography and all were treated by angioplasty. All study patients presented with uncontrolled hypertension in spite of multiple medications; eight had renal functional impairment and two patients had recurrent unexplained pulmonary edema in addition.

Primary pancreatic non-Hodgkin's lymphoma in a renal transplant recipient.

Primary pancreatic non-Hodgkin's lymphoma (NHL) is rare and accounts for less than 1% of all lymphomas. The development of NHL following transplant is well recognized. However, there are no previous reports on localized lymphomatous pancreatic involvement in a transplant patient.

Primary pancreatic non-Hodgkin's lymphomas.

Primary pancreatic lymphomas are rare. We reviewed our experience at King Faisal Specialist Hospital and Research Center; the hospital tumor registry identified five patients with primary pancreatic lymphoma among the 1,212 adult non-Hodgkin's (NHL) cases referred to this institute during 1987-1994. The histology was diffuse large cell in all cases.

Chromophobe cell carcinoma of the kidney. A clinicopathologic study of 21 cases.

The clinicopathologic features in a series of 21 chromophobe cell carcinomas are reviewed. Patients' ages ranged from 30 to 83 years (mean, 53 years), and the number of men and women was roughly equal. Major presenting complaints included hematuria, flank pain, and flank mass.

Fine needle aspiration biopsy of hydatid cysts.

Fine needle aspiration biopsy (FNAB) was performed in 31 patients with hydatid disease by 15 operators in 41 biopsy events during the period 1983-93. The FNABs were unintentionally done without prior clinical suspicion of hydatid cysts (HCs) in 18 patients and intentionally (with prior clinical suspicion of HC) in 13 patients for pathologic confirmation required for specific therapy. The FNABs were performed with the guidance of fluoroscopy (n = 7), CT (n = 14) or ultrasonography (n = 10).

Urethral hemangioma managed with sclerotherapy. Case report.

A 15-year-old boy presented with bleeding per urethram due to extensive urethral hemangioma. Endoscopic sclerotherapy resulted in control of bleeding, resolution of the hemangioma and no stricture formation.

Liver VIPoma: report of two cases and literature review.

Two cases of neuroendocrine tumor in the liver, positive for VIP, without evidence of a primary tumor outside the liver is presented. One patient had a VIPoma syndrome with diarrhea, hypokalemia, and hypercalcemia, all symptoms were reversible after treatment consisting of somatostatin analogue and arterial liver embolization followed by liver resection. The other patient showed no endocrine symptoms.

Ossifying parosteal lipoma with exuberant cortical reaction. A case report.

Lipomas lying close to bone are called parosteal lipomas. They usually cause some bone reaction. We are reporting a dramatic example of this rare condition and have discussed the differential diagnosis and management.

Xanthogranulomatous pyelonephritis: King Faisal Specialist Hospital experience.

Clinicopathologic features in a series of 11 cases of xanthogranulomatous pyelonephritis are reviewed. There were seven males and four females ranging in age from 6-56 years with an average age of 34 years. The disease was unilateral in ten cases and bilateral in one.

Angiographic embolization for control of pelvic genital tract hemorrhage. Report of 14 cases.

Fourteen patients with intractable bleeding of obstetric or gynecological origin underwent transcatheter angiographic arterial embolization. Three patients had postpartum hemorrhage associated with dilutional coagulopathy, anticoagulant therapy and placental leukemic metastases, or placenta percreta. One patient had locally advanced gestational trophoblastic tumor, one had uterine sarcoma and 8 had advanced cervical malignancy.

Mediastinal hydatid disease: report of three cases.

We report three patients who had mediastinal echinococcosis and then review the literature. The first patient had a primary anterior mediastinal echinococcal cyst, the second a mediastinal hydatid cyst, secondarily involving the mediastinum and mimicking Hodgkin's disease, and the third had a primary cardiac and pericardial hydatid cyst. In two patients computed tomography (CT) was helpful in making a preoperative diagnosis before any complication could arise.
