Cardiac Fibromas are primary cardiac tumours more common in children than in adults. Surgical intervention is often not required except in the case of limited cardiac output or significant arrhythmia burden. We present a symptomatic 3-month-old infant who had successful surgical intervention for a giant right ventricle fibroma found on prenatal imaging.

Primary cardiac tumors are rare in infancy and childhood. We describe the features of large intramural ventricular cardiac fibromas discovered in two children. In the first, a left ventricular apical tumor was discovered by means of echocardiography and left ventriculography in a symptomless 8-year-old boy. The intramural fibroma was successfully resected. In the other case, an 8-month-old female infant with severe congestive heart failure, sudden ventricular tachycardia and fibrillation occurred during left ventriculography. At necropsy a tumor was seen bulging in the anterior wall of the left ventricle and in the ventricular septum. Histology showed the tumor to be a fibroma.

A rare case of ossifying fibroma of the temporal bone is presented. Fibro-osseous lesions are benign neoplasms but may show an aggressive behaviour when invading important anatomical structures. The lack of experience in the treatment of those tumours is reflected in the small relative literature. The purpose of this paper is to contribute to the few cases already reported.

Solitary fibrous tumour is a particular kind of mesenchymal tumour, classically arising in the pleura. We report the first case arising in the larynx, associated with a metastasizing adenocarcinoma. The diagnosis is mainly histopathological, especially when strong immunoreactivity for the CD34 antibody is present.

Infantile fibromatosis, one of the fibrous tumours of infancy and childhood, is a fibroproliferative lesion characterized by aggressive local invasion without any tendency to metastasize, the absence of cytological evidence of malignancy and a high rate of local recurrence when incompletely excised. We report a case of infantile (desmoid-type) fibomatosis in a seven-year-old girl arising from the deep lobe of the parotid gland that was treated by complete surgical excision with preservation of the facial nerve. The clinical features, pathology and treatment are briefly discussed.

The cemento-ossifying fibroma (COF) is a mesodermal, non-odontogenic tumour of ectopic multipotential periodontal membrane blast cells. It is aggressive, locally destructive, and has a high recurrence rate. A case report of COF of the petromastoid region is presented. This location has not been described until now. Trauma may act as a trigger to sudden growth of the atopic periodontal tissue. Due to the aggressive behaviour of this tumour and its frequent recurrence radical surgery is needed.
