A case of retroperitoneal fibrosis with ureter compression is reported. Clinical picture and course were determined by the presence of an additional tumor (astrospongoblastoma) of the pons. Extraretroperitoneal tissue changes found at post mortem examination were shown histologically to be foreign tissues of the same type deposited in the retroperitoneal space (disseminated xanthofibrogranuloma). Possible connections between the disseminated xanthofibrogranuloma, the pontine tumor and an albinism also present and multiple nevocytic nevi of the skin are discussed.

A case report of a fibrous histiocytoma of the bladder that presented as total, gross, painless hematuria with compression of the intramural ureter is described. Important pathologic aspects are presented and histiocytic tumors are discussed briefly. Any histiocytic tumor not related to a disease of lipid metabolism is rare and we have found no previous report of a fibrous histiocytoma of the bladder.

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.

Carcinoma metastatic to the ureter is uncommon, only 160 patients having been reported upon to date. During a ten year period, 82 patients with ureteral obstruction, secondary to metastatic disease, were seen at the UCLA Hospital. A critical analysis of the records of these patients revealed important clinical and diagnostic criteria to aid in the evaluation and treatment of extrinsic ureteral obstruction. Tumors of the cervix, prostate, breast and colon-rectum were the most common primary lesions to metastasize to the ureter. Subtle changes in urinary symptoms or in laboratory values should alert the physician to the possibility of ureteral involvement. Early detection of metastatic ureteral obstruction prior to the ravages of uremia may allow time for more aggressive use of adjuvant therapeutic modalities that would, at a later stage of the disease, be ineffectual or contraindicated.

A retrospective analysis of 27 cases of primary carcinoma of the ureter is presented. The ages of the patients ranged from forty-two to eighty-three years, with the highest incidence between the fifth and seventh decades. Males were more frequently affected than females, and the tumors were usually found in the lower third of the ureter. Hematuria and flank pain were the presenting symptoms in the majority of cases. Poorly differentiated invasive tumors had poor prognosis when compared to well-differentiated noninvasive lesions. Total nephroureterectomy with excision of bladder cuff is the preferred treatment for ureteral carcinoma in view of the high rate of ipsilateral tumor recurrence.

A comparison of the prognosis between 2 series of patients with urothelial renal pelvic tumors is presented. One series comprising 70 patients was operated with intrafascial nephrectomy with extirpation of varying length of the ureter. The other series comprising 38 patients was operated with transabdominal perifascial nephrectomy with homolateral adrenalectomy, total ureterectomy and in 28 patients retroperitoneal lymphadenectomy. The 5-year survival was 51% in the patients operated with intrafascial nephrectomy and 84% in the patients operated with perifascial nephrectomy. The difference in prognosis is statistically significant (p less than or equal to 0.01) and cannot be explained by differences in extent of tumor infiltration, tumor grade or tumor size. The main difference in prognosis between the two series was in patients with high stage tumors (Grabstald stage 3 and 4). The 5-year survival was 74% in patients with stage 3 and 4 tumors in the patients operated with perifascial nephrectomy compared with 37% in the patients operated with intrafascial nephrectomy. Since it is not possible with absolute certainty to determine tumor stage before the operation, an aggressive attitude against urothelial renal pelvic tumors is recommended. Thus the patients should undergo transabdominal perifascial nephroureterectomy including a cuff of the bladder wall and homolateral adrenalectomy. In patient with bilateral tumors, renal insufficiency of tumor in a single kidney parenchyma saving partial resection must be performed.

Two cases of papillary carcinoma of the bladder are presented in which the ureter could not be demonstrated by standard radiographic techniques. Computed tomography (CT) allowed identification of the tumor filled ureter. Intraureteral papillary tumor has a radiographic density (CT number) above that of water but less than that of the enveloping ureter.

A case is reported, the 33rd to be published in the literature, of malignant retroperitoneal xanthogranuloma. The tumor involved 2 cm of the right ureter at the junction between the middle and upper thirds. The middle third of the ureter was removed and ureteral continuity established by end to end ureteral anastomosis. The patient died fourteen months later probably from metastases, though the presence of these was not confirmed.

Carcinoma metastatic to the ureter, representing hematogenous or lymphatic spread from a distant primary neoplasm, was diagnosed in 39 patients. Although the lesions are uncommon and usually represent late manifestations of malignant disease, earlier recognition and relief of urinary tract obstruction may allow for improvement in symptoms and survival.

We report on 3 patients who presented with an acute onset of abdominal pain, a palpable abdominal mass and a rapid decrease in hemoglobin. In 2 patients a spontaneously ruptured hypernephroma was found and the other patient had a squamous cell carcinoma of the ureter with bleeding into the tumor. Although in all 3 cases the tumors were at an advanced stage of development, the patients had been entirely free of urological symptoms until shortly before hospitalization. The importance of considering the possibility of spontaneous rupture of such a tumor in the evaluation of cases of an acute abdomen is stressed.
