A 64-year-old woman presented with retroperitoneal lymphoma metastatic to the left ureter. Lymphoma was not diagnosed and her clinical course was not fully explained until after surgery. The lack of superficial lymphoma delayed diagnosis and therefore prevented effective treatment. Her situation became unmanageable when it was complicated by bacteremia (E coli) and fungemia (Candida albicans).

A 65-year-old woman had pancytopenia, splenomegaly, and an inaspirable bone marrow. Diagnostic evaluation demonstrated that she had both leukemic reticuloendotheliosis (LRE), or hairy cell leukemia, and an additional lympho-reticular neoplasm, most likely a "histiocytic" lymphoma. The diagnosis of LRE was based on the histopathology of spleen tissue and of a bone marrow biopsy specimen. The diagnosis of diffuse "histiocytic" lymphoma was based on the histopathology of a splenic hilar and a mesenteric lymph node, tumor nodules in the kidney and spleen, and tissue from a mass obstructing a ureter. This is the first well-documented association of a second lympho-reticular neoplasm with LRE. Even relatively gently treatment of the "histiocytic" lymphoma resulted in fatal pancytopenia, illustrating the restricitons on therapy imposed by the marrow impairment due to the LRE.

Four patients with renal lymphoma were evaluated by computed tomography and presented the following different manifestations: (a) multiple large and small nodules infiltrating each kidney; (b) a single large renal mass extending into the perirenal space; (c) diffuse infiltration of both kidneys; and (d) lesion of the renal hilus encasing the renal pelvis and proximal ureter of one kidney. Computed tomography is a sensitive, noninvasive imaging modality that should be performed early in the course of disease in patients with known or suspected lymphoma.

Metastasis to the ureter may evolve by direct or indirect extension and invasion from the most common malignant tumors, such as breast, colon and lymphoma. A case of an unusual extension of metastatic infiltration to the ureter, kidney and other intra-abdominal and retroperitoneal structures is reported. Such a case has not been presented roentgenographically in the urologic or radiologic literature.

Among the causes of constricted ureter is benign or malignant encasement. The diagnosis of ureteric encasement is frequently overlooked, even by well informed clinicians and radiologists. The most common benign cause is retroperitoneal fibrosis and the most frequent malignant causes are extension from an adjacent primary tumour, true metastases to the ureter and lymphoma. Lack of recognition of the process may lead to mistaken diagnosis of an inflammatory stricture or infiltrating transitional cell tumour, with resultant inappropriate management. A sign which appears to be almost specific for encasement, the bullet and bodkin configuration, is described here. Newer imaging modalities such as computed tomography and ultrasound, while helpful, are probably less sensitive and less specific than the retrograde ureterogram because a detectable mass is not always present.

An immunohistochemical study of a rare initial manifestation of non-Hodgkin's lymphoma (NHL) in the ovaries is presented. There have been very few reports to date on immunohistochemical studies of lymphoma involving the ovaries. A 53-year-old woman suffering from lower abdominal pain and abnormal genital bleeding was diagnosed as having a tumor in her left ovary by ultrasonic echograms and CT scanning. The patient underwent a simple total hysterectomy and bilateral salpingo-oophorectomies. The tumor, measuring 14 x 10 x 10 cm, was located in the left ovary and extended to the major omentum, mesocolon and left ureter. The histology of the tumor was that of NHL showing diffuse proliferation of small cleaved cells. Immunohistochemical studies of the ovarian tumor showed that the tumor cells were of a B-cell lymphoma nature with LCA+, MB-1+, lambda+, keratin-, IgG-, IgM-, IgA-, kappa-, and MT-1-. Although the main lesion involved the ovary, the case could not be identified definitely as primary lymphoma of the ovary.

A 45-year-old man was admitted to hospital on November 26, 1985 with the chief complaint of left hypochondrial pain. Excretory and retrograde pyelography revealed left hydronephrosis due to extrinsic obstruction of ureter. Computerized tomography and angiography revealed that a tumor of the small intestine was the cause of ureteral obstruction. In addition to the presence of a tumor, a fistula in the small intestine was disclosed on the upper gastrointestinal series. During the operation, a large mass which involved several organs was identified without mobility. The sophisticated operation was composed of wide resection of small intestine including the tumor, left hemicolectomy, left nephroureterectomy, splenectomy, partial pancreatectomy, duodeno-ileostomy and transverse sigmoidostomy was done on December 19, 1985. Pathological diagnosis was malignant lymphoma, diffuse small cell type infiltrating ureter, kidney and perirenal connective tissue. Because of poor postoperative course systemic chemotherapy was not performed and he died of disseminated intravascular coagulation on April 2, 1986.

This is a survey of 234 pediatric patients in whom staging laparotomy/splenectomy was carried out (1975 to 1981) in the course of the Intergroup Hodgkin's Disease in Childhood Study (IHDCS). Relapse has occurred in 44 of these patients, and 12 have died, 7 secondary to extension of lymphoma, 2 with herpes or pneumocystis infections, 2 with leukemia, and 1 from an unrelated accident. During the period of surveillance (mean 5.5 yr), five episodes of bacterial sepsis (positive blood cultures) have occurred, including two due to Streptococcus pneumoniae; and three, to Hemophilus influenzae. The former occurred in the small group of patients in this series who had not received the prescribed pneumococcal vaccination. No fatalities were associated with these septic episodes. Intestinal obstruction secondary to adhesions (benign) occurred in eight patients and was managed without intestinal resection or mortality. One patient required operative release of an obstructed ureter following laparotomy, and one, oophorectomy for an infarcted (transposed) ovary.

One hundred twenty-six patients with the diagnosis of lymphoma underwent staging with both lymphangiography and computed tomography (CT) of the abdomen and pelvis. These patients were retrospectively studied to determine the optimal imaging modality for follow-up. Six hundred seventy-four CT scans were correlated with 138 lymphangiograms and 840 follow-up KUB (kidney, ureter, bladder) radiographs. In 21 patients there was evidence of relapse, and in 105 the disease had regressed or remained stable. In all patients with evidence of progression or regression on the CT scan, there was a concomitant change in opacified lymph nodes on the KUB radiographs. It is recommended that the initial staging of lymphoma be done with lymphangiography and CT. If the findings of both are positive, then follow-up should consist of only KUB radiography. If progression is detected, restaging with CT may also be performed. This approach will not only reduce the radiation dose but will also save time and money and enable a more efficient use of radiologic equipment.

After vascular graft surgery within the pelvic area, urological complications occur in about ten percent of the patients. Overlooking 310 cases, four patients suffered from ureteral lesions and 21 patients had ureteral obstructions. Possible causes for ureteral obstructions are positioning of the ureter between vessel and prosthesis, hematoma, lymphoma, anastomotic aneurysm, prosthesis infection, Morbus Ormond as well as trophical lesions of the ureter wall. Use of ureteral splint could prevent surgical intervention in many cases. Application of prophylactic pre-operative splinting is recommended in case of large aneurysm, previously injured kidney and single kidney.
