A 37-year old woman had received multiple radiation treatments between the ages of 6 months and 15 years for an extensive cavernous hemangioma of the left side of the face. At the age of 27 years, a biopsy specimen from a lesion of the left buccal commissure disclosed squamous cell carcinoma arising in chronic radiodermatitis. Multiple cutaneous lesions were excised surgically, and extensive skin grafting of the left side of the face was performed. At the age of 35, she developed a tumor of the left upper and lower eyelids that extended into the orbit, which proved to be a sebaceous gland carcinoma. Following left orbital exenteration, the tumor promptly recurred in the socket. The patient died with widespread metastatic lesions nine months after exenteration. This case, which, to our knowledge, represents the fourth example of postradiation sebaceous gland carcinoma of the eyelids, differs from the previously reported cases in that the radiation therapy had been given for a benign cutaneous condition.

Testicular tumors in infants and children are rare and most of them are malignant. Embryonal carcinoma is the most common childhood neoplasm, while seminoma is predominantly found in adults. Hemangioma of the testis is an extremely rare tumor, only 2 cases having been reported in infants.

Symptoms of inspiratory stridor, dyspnoa and cyanosis appeared in a four month old boy. After the direct laryngoscopy and biopsy a hemangioma simples of the larynx was diagnosed. The tumor itself was successfully treated by cryosurgery. The advantages of this therapy were pointed out and the cryosurgery can be recommended in cases of larynxangioma.

A case of splenectomy with thrombocytopenia but without hypersplenism is described. The etiology, proven by splenectomy, was a splenic angioma. The isotopic examinations necessary to localize the site of a vascular tumor and the relations between thrombocytopenia and hemangioma are discussed.

Experience with Radio Isotope Myelography is reported here. 169Yb-DTPA as a tracer was intrathecally injected at lumbar region in twenty three patients with various spinal cord lesions. The first scanning is perfomed after comfirming by gamma-camera that the tracer reaches to the lesion, the second and the third scannings are done according to the ascending rate of the tracer. (I) Normal scintimyelogram (A) In normal case, the shape of the Radio Isotope Myelogram well corresponds the shape of anatomical subarachnoid space. (B) In normal adult cases, the tracer comes up to the cisterna magna in 20-25 minutes after the lumbar injection. Therefore, the scintimyelographic diagnosis should be made not only by the shape but also by the ascending rapidity of the tracer. (II) Abnormal scintimyelogram Abnormal scintimyelograms could be summarized as following three categories. (A) "Delay": It means delay of the ascending of the tracer. Besides, "Transient delay" found in a case of Arnord-Chiari's malformation was proposed. (B) "Partial block": It meas a defect at the level of the lesion. This "Partial block" were observed in cases of spinal cord angioma, cervical spondylosis and spinal cord tumor etc. (C) "Complete block": It means the stagnation of the tracer below the lesion. To sum up, Rario Isotope Myelography, especially in partial block, can more easily and more sensitively represent the maximum extent of the spinal cord lesion than other myelographic study or angiographic one. On the other hand, we can not qualitatively diagnose about the lesions by its indistinct border.

Nine cases have been presented in detail to illustrate some of the varied causes of sudden neurological deficit in childhood: arteriovenous malformation, cryptic hamartoma, berry aneurysm, mycotic aneurysm, intraspinal arteriovenous malformation, brain tumor, migraine, arteritis, and multiple sclerosis. The Boston Children's Hospital experience with aneurysms and intracranial arteriovenous malformation has been summarized. It is noteworthy that a cutaneous hemangioma overlay one cranial and one intraspinal arteriovenous malformation. One small but deep cerebral arteriovenous malformation apparently destroyed itself after its second hemorrhage. Not only have multiple sclerosis and a brain tumor mimicked a vascular lesion, but a series of vascular accidents was misdiagnosed first as multiple sclerosis then as a thalamic tumor. The many possible causes of childhood strokes has been thoroughly cataloged in the Report of the Joint Committee for Stroke Facilities in 1973 (11). Children may be more susceptible to strokes because of congenital abnormalities such as congenital heart disease, hemophilia, and sickle cell anemia, or by diseases which more commonly occur in this age group, such as leukemia. The likelihood of brain abscess in cyanotic congenital heart disease is stressed. Arteriographic studies in our series have been safe; however, there have been reports of probable worsening of symptoms in children with multiple cerebral occlusive lesions in the presence of homocystinuria.

When first seen in May, 1974, this 7-week-old child presented a rapidly enlarging hemangioma involving her face, scalp, oral mucous membranes and pharynx. Because of the development of stridor and complete closure of the eyelids of one eye by the hemangioma, the child was placed on systemic corticosteroid therapy. This was continued for a three-month period at which point it was discontinued. There was unquestionalbe shrinkage of the tumor during therapy. The stridor disappeared and the eyelids opened within a few days. Within six days of discontinuation of the corticosteroids, there was sudden enlargement of the lesion and reappearance of stridor which again subsided after a six-week course of systemic corticosteroids. Currently, the child is still under observation. It is anticipated that further spontaneous resolution will take place but that she will require plastic surgery for some of the residual deformities. The questions of ocular involvement, cardiac enlargement, occlusion of the pharyngeal airway, and arteriovenous anastamoses were raised in this child. Newer treatments including embolization treatments and cryotherapy were considered for this child but were not pursued since the growth of the hemangioma came to a virtual standstill and the child is otherwise thriving.

The data on 15 patients with hemangioma of the synovial sheath of the knee joint are reported. It is the author's opinion that surgical removal of the tumor is the most radical method of treatment for hemangiomas. Among 15 patients such procedure was accomplished in 6, in the remainder biopsy or partial removal of the tumor followed by radiotherapy were performed. Late results were followed up in 9 patients.

A newborn infant with a large hepatic hemangioma developed congestive heart failure, consumption coagulopathy, microangiopathic hemolytic anemia, and obstructive jaundice. The patient was mildly heparinized (250 units per kg and day) and underwent successful resection of the tumor without lobectomy at the age of 3 days. Blood volume increased from 93.9 ml/kg at the age of 5 h to 124.2 ml/kg prior to surgery. Red-cell mass simultaneously decreased from 53.8 to 39.4 ml/kg. The increase of blood volume is explained by congestive heart failure, the decrease of red-cell mass by intravascular coagulation within the tumor resulting in formation of thrombi and microangiopathic hemolytic anemia. A review of the literature on infants with symptoms caused by an intrahepatic hemangioma during the first month of life confirms that surgical intervention is the treatment of choice for infants with giant solitary hemangioma of the liver.

A 2 month-old infant was admitted because of respiratory distress and thoracic assymetry. X-ray films revealed a distension of the left lung. A pneumo-angiography showed a cardiac silhouette displaced to the right and a normal vascular tree of the left lung. The rapid impairement of the clinical picture led to an exploratory thoracotomy. A tumor at the level of the left hyparterial bronchus was found. The histologic characteristics of the tumor were those of a hemangioma. Within the spectrum of broncheal tumors, hemangioma belong to benign mesenchymatous tumors and have a good prognosis providing that their removal is complete.
