The arteriographic findings in two cases of hemangiosarcoma of the spleen with liver metastases are described. These are the second and third reported cases of angiographically demonstrated malignant splenic tumors of vascular origin. Despite the absence of tumor vessels, there were multiple vascular takes in the arterial through the venous phase, mimicking benign cavernous hemangioma. Multiple metastases in the liver were the only clue to malignancy. Arteriography combined with liver-spleen scintigraphy not only provides information which is valuable in the preoperative diagnosis but also aids in management of the patient.

A series of 26 cases of hemangioma of the skull and review the literature are reported. The frontal localization was most frequent, contrary to the data of the literature suggesting the predominance of the parietal localization. The reported predominance of females has not been confirmed. In the present series the relation of males to females was 17:9. The radiological findings and treatment of hemangiomas are discussed. Direct puncture and injection of contrast medium is the best method for the visualization of the tumor. Treatment should be surgical consisting of total extirpation of the tumor with a margin of the healthy tissues. Direct extirpation is indicated only when soft-tissues are involved and there is no bone lesion. The en-bloque method is the technique of choice.

In a boxer dog aged 12 years who had deceased from circulatory insufficiency due to purulent endomyocarditis, there occurred a Leydig cell adenoma of the testis and multiple cutaneous naevi (haemangioma, pigmented naevus and various cutanous organ naevi). The findings have been discussed with reference to the race disposal to neoplastic growth.

Congenital subglottic hemangioma causes life-threatening airway obstruction during the first few months of life. The mortality rate of recognized and untreated cases justifies active treatment, and although radiation therapy is currently most favored, it carries a risk of inducing malignant change in the thyroid gland later in life. A series of 11 patients with laryngeal hemangiomata is reported, conventional radiotherapy was utilized in the first seven patients, and placement of a radioactive gold grain directly into the lesion was used in the last four patients. This technique offers maximal tumor dose with minimal thyroid gland irradiation compared to treatment by conventional radiotherapy, and its successful use in these four patients is reported as worthy of further trial.

Spontaneous regression of sinus pericranii has not been reported in the literatures. The aurthors presented a very rare case of sinus pericranii, which was diagnosed as early as nine days after birth and completely disappeared in seven years. The patient was a nine-day-old boy from normal delivery in full term, who had a soft tumor simulating cephalhematoma in the right parietal region. The overlying scalp looked like a hemangioma bitemporally connecting with strikingly dilated scalp veins. Soft X-ray examination of the skull revealed a homogenous mass and a small bone defect beneath the mass. Venous blood was punctured from the tumor. By means of direct injection of contrast media into the tumor, the superior sagittal sinus as well as many extracranial varicositous veins were shown. No intracranial vascular anomaly. In a year the tumor spontaneously declined and in the following seven years it disappeared completely. Pathogenesis of this lesion was discussed with special reference to cephalhematoma and a possibility of spontaneous regression of sinus pericranii was stressed.

From 1971 to 1976 surgery was done on 11 patients with benign tumors of the liver in the Surgical Department of the University of Mainz. Histological examinations revealed focal nodular hyperplasia in 5 cases, liver cell adenoma in 2 cases, caverneous hemangioma in 2 cases, cystic liver disease in 1 case, and an idiopatic peritoneal liver cyst in 1 case. Benign tumors of the liver are rare. Clinical symptoms in these cases are inconspicuous. In 5 patients the diagnosis was made coincidentally. Preoperative diagnosis depends mainly on angiography. Since an exact histological diagnosis cannot be made otherwise, surgery is imperative. Big tumors leading to displacement of intestinal or biliary organs ought to be removed in toto; this allows complete histological work up and exclusion of malignancy, and it does prevent recurrence of the tumor as well. In 8 of 11 patients tumors localized peripherally in the liver could be removed surgically without complications.

A painful intracortical and subperiosteal lesion of the fibula with a 14 year follow-up is reported to regress to a painfree state. Infection is favored in the differential diagnosis. Biopsy with histological and radiographical correlation are essential for exclusion of: osteoid osteoma, osteoblastoma, periostitis, glomus tumor, eosinophilic granuloma, enostosis, hemangioma of bone, giant cell tumor, simple cyst, aneurysmal bone cyst, non-ossifying fibroma, polyostotic fibrous dysplasia, hyperparathyroidism, Paget's disease, localized area of avascular necrosis, stress fracture and even metastatic disease.

In order to estimate end effects of chronic prolonged gammairradiation of dogs, an exposure of 80 animals to irradiation was terminated and they were followed up closely. Out of 80 animals 30 dogs (1st series) were irradiated for 3 years and 50 dogs (II series) for 6 years. The dogs were exposed to irradiation at doses of 21 to 190 rad per year. Out of the total number of animals 22 dogs died. Post-mortem examinations showed neoformations in 13 animals (7 malignant and 12 benign neoformations). The highest number of tumors developed in dogs of the II series (10 out of 11) one-two years after irradiation (6 malignant tumors--malignant pheochromocytoma of adrenals; malignant adenoma of the hypophysis: polymorphocellular sarcoma of the liver; leucomyosarcoma of the uterus; bladder cancer; breast cancer; and 10 benign tumors--pancreatic adenoma; liver angioma; 2 papillary adenomas of the prostate; 3 renal adenomas; lipoma; polyps of the gall-bladder). Animals of the 1st series displayed 3 neoformations (1 malignant tumor--bladder tumor and 2 benign tumorsliver hepatoma and spleen angioma) 4--5 years after irradiation.

Tumors involving the base of the skull are often occult and may become quite large before detection is possible. Symptomology varies depending upon the nature of the tumor and its placement. These neoplasms have frequently been considered inoperable simply because of their location, but in recent years microsurgical technique and high speed air drills have allowed the modern temporal bone surgeon to gain improved access to the skull base. A wide variety of surgical approaches to tumors in this area have been described in the past 20 years: translabyrinthine, middle fossa, transcochlear, retrolabyrinthine, retrosigmoid, transpalatal-transclival, and through the jugular bulb. The purpose of this paper is to review the indications, complications, and results of each of these procedures in relation to specific tumors involving the skull base. Case reports illustrate the diagnosis and surgical management of a variety of unusual neoplasms, including an extradural meningioma of the temporal bone and clivus, a low grade squamous cell carcinoma on the tegmen in a radical cavity, a large primary cholesteatoma, an osteoblastoma of the temporal and occipital bones, an XIth nerve neuroma in the jugular bulb area, and an osseous hemangioma involving the facial nerve at the geniculate ganglion.

The cavernous hemangioma of the liver is frequently seen as small tumor without any symptoms, but only rarely its diameter is more than 4 cm (161 cases in world literature). We can report on an additional patient. The peculiarities in this case were the tumor size, the presence of numerous phleboliths and the contrasting of the tumor taking place mainly from the venous part of the vascular bed of the liver. The main indication for a surgical intervention is the danger of rupture, but disturbances of the coagulation as well as intestinal suppression symptoms have also to be taken into consideration. The intraoperative tactics ought to be a standardised resection of the liver. The cavernous hemangioma must be differentiated from the hemangioendothelium: this usually occurs in children, causes cardiac failure due to a. v. shunts, and responds to conservative therapy (corticosteroids, radio-therapy).
