Malignant hemangioendothelioma, localised to the skeleton of the lower limbs, to the exclusion of any other bony or visceral involvement, complicated by hemolytic anemia and spontaneous fractures, edl to death in spite of bilateral amputation, less than one year after its chance discovery. The multifocal character of the bony lesions, which is common, may suggest either rapidly developing metastases, or multicentric development of the tumour. The clinical, radiological and laboratory signs--pure osteolysis of large size without condensation nor periostosis, are not specific. Pathological examination permits recognition of the vascular origin of the tumour but does not always permit one to recognize its malignant nature. Treatment, which is mainly surgical, is often ineffective.

The hemophagocytosis or the process of ingestion of blood cells by phagocytes and macrophages of the mononuclear phagocytic system (MFS), is a phenomenon that rarely could be observed in the morphological examination of the bone marrow aspirate. Occasionally it is present in certain pathologic conditions such as, malignant histiocitosis, autimmune hemolytic anemia, or some chronic inflammatory diseases. The capacity of ingestion is not an exlusive property of the phagocytes and macrophages of the MFS, so that different neoplastic cells can show it too. This study analyzes the presence of hemophagocytosis by neoplastic cells in a total of 552 bone marrow aspirates corresponding to a series of 130 patients with acute leukemia and 422 patients with diverse solid tumors. In the group of patients with acute leukemia, hemophagocytosis by blastic cells was observed in five cases with acute monocytic leukemia. In the other group with solid tumors, hemophagocytosis was present in three patients with oat-cell lung carcinomas and diffuse bone marrow metastases. The interest of the evaluation of hemophagocytosis by neoplastic cells in the morphological examination of the bone marrow is stressed, as well as it possible value in the cytological diagnosis of acute monocytic leukemia. However, in these circumstances a sdiffuse metastases by solid tumors should be always discarded, since their cytomorphological characteristics are in most cases superimposed to those of the leukemic bone marrow infiltrate.

Presentation of a case of disseminated intravascular coagulation with micro-angiopathic hemolytic anemia, associated with a micro-carcinoma of the prostate. In the absence of other etiology it is postulated that the carcinoma was responsible for the hematological disturbance in spite of its small size andlack of either metastases or mucin secretion. The unusual discovery in this disease of bony necroses of the vertebrae, which are attributed to ischemia following micro-thromboses, is also discussed.

In view of the possible role of platelets and coagulation mechanisms in the growth and dissemination of solid tumors, a number of hematological parameters were followed during development of an experimental syngeneic tumor in mice, Lewis lung carcinoma. This tumor, when transplanted i.m. in C57BL/6 mice, grows locally and spontaneously metastasizes to the lungs. The transplanted animals survive for about 4 weeks. Metastases are visible from the third week. A slight but constant increase in plasma fibrinogen level and marked thrombocytopenia were first observed during the second week after tumor implantation. No other significant changes in coagulation and fibrinolysis parameters were detected. Moreover, the animals developed marked hemolytic anemia, possibly microangiopathic in origin. 125I-labelled fibrinogen survival was decreased by about 20% during the second week after tumor implantation and was not further reduced later. Fibrinogen turnover was progressively accelerated, being more than doubled by the end of the third week. Labeled fibrinogen accumulated in the primary tumor and in the lungs (its rate of disappearance from the tumor was much slower than that from lungs or blood). 51Cr-labeled platelet survival did not change throughout the observation period, whereas platelet turnover was markedly reduced from the end of the second week, suggesting defective platelet production. 51Cr-labeled RBC survival was drastically reduced to about 30% of the controls starting from the second week. The occurence of low-grade, localized intravascular coagulation could be suggested on the basis of these data. Moreover, when Lewis lung carcinoma cells were abruptly injected i.v. through the tall vein, more impressive signs of intravascular coagulation could be seen. Indeed, there was a rapid decrease in the number of platelets, a reduction in fibrinogen, and an increase in fibrin-fibrinogen degradation products. The effects of i.v. injection of Lewis lung carcinoma cells indicate a relevant interference of cancer cells with the hematostatic system. In contrast, the tenuous evidence fo coagulation disorders in animals receiving injections of tumor cells i.m. seems to indicate a limited effect on hemostasis of the same cells during i.m. tumor growth.

A 76-year-old man with spontaneous rupture of a hemangiosarcoma of the spleen, together with a review of 49 previously reported patients with splenic hemangiosarcoma are presented. Twenty-three were women and 27 were men. All but 3 were adults. Fiften were 50-59 years of age. The symptomatology was nonspecific. Three patients developed microangiopathic hemolytic anemia. Spontaneous rupture occurred in 17 cases (34%). Metastases occurred in 42 cases; they were primarily hematogenous and most often in the liver. Lymph node involvement, however, was present in 13 cases. The prognosis of untreated splenic hemangiosarcoma is poor. Three of 25 patients survived a year or more after the initial onset of symptoms. Splenectomy before rupture is advisable, since 5 of 19 patients survived at least 1-5 years. It is suggested that hemangiosarcoma be considered in patients with: 1) splenomegaly without evidence of malignant lymphoma or leukemia, 2) splenomegaly with microangiopathic hemolytic anemia, and 3) unexplained intraperitoneal hemorrhage.

A woman with a history of drug allergy, renal impairment and carcinoma of the breast with pulmonary micrometastases developed haemolytic anaemia and Stevens-Johnson syndrome following the use of mefenamic acid, paracetamol (acetaminophen) and furosemide (frusemide). In addition there was severe cholestatic hepatitis in the absence of clinical evidence of sepsis, biliary obstruction or recurrent metastases. The rash resolved on steroid therapy but the patient eventually died from both renal and liver failure. Acute tubular necrosis with a background of chronic tubulointerstitial nephritis was also found at autopsy. Although in the presence of multiple drug therapy the causative agent cannot be identified with absolute certainty, the association of these severe idiosyncratic hepatic and dermatological reactions with haemolytic anaemia strongly suggests mefenamic acid as the most likely culprit.

To evaluate the influence of [2-(3-carboxy-1-probylthio)-4-methyl-1,3-thiazole]acetic acid (tiprotimod, HBW 538) on the host defense mechanisms, a number of experimental studies in different animal models were performed. The prophylactic treatment of NMRI mice with tiprotimod significantly prolonged the mean survival time of the animals after intravenous infection with Candida albicans 200/175 and increased the resistance to the fungal infection to 180% in comparison to controls. In vitro the drug showed no direct fungistatic or fungicidal activity. In an experimental model of persistent systemic candidiasis Balb/c mice infected intravenously with Candida albicans were treated with the immunomodulator tiprotimod after the fungal colonization of kidney was manifested (3 days post infection). The treatment of the mice after the infection resulted in a reduction of the infectious load and the abscess formation in kidney as well as in a decrease of numbers of yeasts in the urine. In the syngeneic B16 melanoma tumor model tiprotimod significantly prolonged the medium survival time and reduced the number of visuable metastases in the lungs even when applied after resection of the primary tumor graft. Tiprotimod also beneficially influenced the course of the disease in two murine graft-vs-host models (hemolytic anemia and immune complex glomerulonephritis) which lead to a B cell mediated autoimmune disease with fatal outcome. The application of the drug in the induction phase mitigated the development of the diseases and prevented animals from dying.(ABSTRACT TRUNCATED AT 250 WORDS)

This report describes cardiac angiosarcoma in a 62-year-old man. The patient presented with metastatic pulmonary and extradural spinal cord tumors of unknown origin. During the course, he developed hypoxemia, gastrointestinal bleeding, thrombocytopenia, and microangiopathic hemolytic anemia. Anticancer therapy could not be initiated because of his poor general condition, and he died. Autopsy revealed angiosarcoma in the right atrium. Metastases were found in the lungs, liver, adrenals, gingiva and vertebrae. The various hematologic abnormalities were probably the result of aberrant hemodynamics caused by the presence of a large amount of neoplastic vascular tissue.

Twelve autopsy cases of carcinomatosis of the bone marrow were examined clinicopathologically. Among them, 7 were gastric adenocarcinoma, and the other 5 were a rectal carcinoid and carcinomas of the lung, prostate, maxilla and kidney, respectively. The gastric cancers were almost all poorly differentiated adenocarcinoma with mucin production and presented poorer prognoses than the other cancers. Leukoerythroblastic anemia, microangiopathic hemolytic anemia and DIC were found more frequently in the gastric cancers than in the others. It is concluded that the evolution of these critical hematologic disorders may be dependent on differences of histologic type, original focus and cancer-host interactions as well as wide-spread skeletal metastases of cancer cells.

A case of paraneoplastic DIC syndrome (asymptomatic carcinoma of the gastric fundus with multiple metastases) is described. Initially, differential diagnosis hesitated before thrombotic thrombocytopenic purpura (Moschowitz' syndrome), given the presence of grave microangiopathic haemolytic anaemia as a major symptom. The main characteristics of Moschowitz' syndrome and the most frequent causes of DIC are described in the discussion.
