Peritoneal washing therapy for pseudomyxoma peritonei.

Two patients with pseudomyxoma peritonei (PP) had repeated intraperitoneal washing with 5% dextrose in water. Both responded to this therapy with decrease in abdominal girth. The second patient is alive, without abdominal distention, more than 112 weeks since beginning peritoneal washing therapy (PWT) for ovarian PP. Biochemical assays of urine before and after PWT show that acid mucopolysaccharide is excreted in the urine, probably after being absorbed through the peritoneal surface. The long-term effects of this procedure on renal function are not known, but PWT appears to be reasonable and safe ambulatory therapy for PP.

Angiogenic nature of the "intravascular bronchioloalveolar tumor" of the lung: an electron microscopic study.

An intravascular bronchioloalveolar tumor of lung (IVBAT) was studied with electron microscopy. Based on ultrastructural evidence and information obtained from the literature, we propose the following: (1) IVBAT is a true pulmonary neoplasm with distinctive morphologic features; (2) it consists of cells with endothelial characteristics and is probably derived from multipotential mesenchymal reserve cells; (3) it is not related to the typical bronchioloalveolar tumor of lung; (4) a more appropriate designation for this unusual pulmonary neoplasm is "sclerosing angiogenic tumor."

Metastatic basal cell carcinoma.

The primary mode of spread of basal cell carcinoma is by direct extension. From 1894 to June 1977, 119 cases of metastatic basal cell carcinoma were reported in the world literature. We wish to report five additional cases. It is our feeling that the spread of these tumors is by the interstitial route. It is standard teaching that the interstitial embolic spread of cancer does not occur, but these five cases give strong supporting evidence to the previously reported suggestion that this route of spread may be common. The concept has considerable implications regarding treatment of most cancers.

Thyroid carcinoma. Immunology, irradiation, and lymphocytic infiltration.

Patients undergoing thyroidectomies at Evanston (III) Hospital, during a six-month period had immunological studies performed preoperatively. No differential could be found between those with carcinoma or benign pathologic findings. T- and B-cell distribution and lymphocytic response to mitogens varied widely. Quantitative immunoglobulins showed slightly increased levels of IgG in patients with carcinoma and thyroiditis in comparison with those patients with adenomas. Antithyroglobulin antibodies were negative in all patients. Pathology slides from 107 patients with thyroid carcinoma between 1972 and 1978 at Evanston Hospital were reviewed for the presence of thyroiditis, either focal or diffuse. It was found that 50% of all carcinomas had either diffuse or focal thyroiditis. Diffuse thyroiditis was more common in patients with no history of irradiation and papillary carcinoma, and in younger age groups.

Pancreatic duct arteriovenous fistula and the metastatic fat necrosis syndrome.

This report summarizes the course of a patient with asymptomatic chronic pancreatitis associated with hemorrhage into the pancreatic duct and metastatic fat necrosis. Retrograde cannulation of the pancreatic duct and superior mesenteric arteriography established the presence of a pseudocyst with a pancreatic duct-arteriovenous (DAV) fistula as the cause of the syndrome. Ligation of feeder vessels with external drainage of the cyst as the initial surgical procedure stopped the bleeding but failed to prevent recurrence of the pancreatic duct-venous fistula. A pancreaticoduodenectomy with resection of the cyst and fistula was required to arrest destruction of distant tissues. Although serum and urine amylase concentrations were markedly elevated, serum lipase levels were normal throughout the patient's course. Elevation of serum lipase does not seem to be a necessary condition for the development of the metastatic fat necrosis syndrome.

Angiosarcoma of the heart. Diagnosis by echocardiography.

Angiosarcoma of the heart is a rare tumor infrequently diagnosed ante mortem. The clinical presentation is usually that of pericarditis or congestive heart failure. This case report illustrates the contribution of echocardiography in suggesting the diagnosis.

Endodermal sinus tumor of the ovary. The orphan tumor.

The endodermal sinus tumor of the ovary is a rare and highly lethal germ cell tumor. At least 10 different names have been applied to it, and so long as its name remains unsettled the collection of information will continue to be greatly impeded. One of the patients who came under our observation died after 21 months despite surgical removal of all evident disease followed by radiation and chemotherapy; the other patient, whose tumor could be removed only partially, and who received intensive chemotherapy for 4 months but refused all treatment thereafter, is well without evidence of disease 3 years after the initial diagnosis was made. Despite the dismal outlook for patients with this tumor, a few encouraging features emphasize the need to report new cases as they appear, and to continue the search for agents that will control it.

Small bowel perforation secondary to metastatic carcinoma of the lung.

This is a report of small bowel perforation secondary to a metastasis from a primary adenocarcinoma of lung in a 62-year-old woman five months after resection of the primary tumor. She had received radiation therapy and corticosteroids after surgery. Features of this and five previously reported cases are discussed. Modern therapy may alter the course of pulmonary cancer resulting in more frequent observation of this rare complication.

Lobular carcinoma in situ of the breast.

Lobular carcinoma in situ (LCIS) of the breast is commonly identified as an incidental finding in breast biopsies performed because of either a mammographic abnormality or a palpable mass. Although long recognized as an entity, the significance and optimal treatment of LCIS remains controversial. Initially regarded as a pre-invasive form of breast cancer analogous to ductal carcinoma in situ (DCIS), LCIS was treated by mastectomy. As evidence mounted for an equal risk of invasive carcinoma in both breasts, bilateral mastectomy was advocated by some. More recent studies suggest that LCIS is a marker for increased risk rather than a true precursor of invasive carcinoma, and this allows a more conservative approach. The pathologic aspects and natural history of LCIS are discussed.

Cytologic features of well-differentiated sclerosing liposarcoma in aspirated samples.

The histologic, cytologic and ultrastructural features of two cases of a rare variant of liposarcoma, the well-differentiated sclerosing type, are presented. These tumors are characterized by lipoblasts (in different stages of development), atypical fibroblasts, multinucleated floret cells, lipocytes and delicate, dispersed collagen. The differential diagnosis includes other types of liposarcoma and three benign lipomatous lesions: the pleomorphic lipoma, the atypical lipoma and the spindle cell lipoma. The latter three neoplasms are composed of fibroblasts, lipocytes and coarse collagen and may have typical lipoblastlike or fibroblastic cells. Given the difficulty in distinguishing these lesions, both cytologically and histologically, the clinical presentation and the tumor location become essential in rendering the diagnosis of sclerosing liposarcoma.
