Ossified cephalhematoma is a rare clinical entity and a pathological curiosity. Even though cephalhematoma is frequently encountered, ossified cephalhematoma is seen only sporadically and is restricted to only few case reports in the literature. Its pathogenesis is unclear, and the clinical course is different in neonates and juveniles.

AbstractLipomata are the most common benign tumour of the head and neck. They may undergo a variety of changes, one of which is ossification which, although rarely seen, has a characteristic radiographic appearance. We present a case of a retropharyngeal lipoma which demonstrates ossification and discuss the features which differentiate this from an ...

Calcification of pituitary adenomas as a histopathologic finding is reported in up to 25% of all degenerated adenomas. On the other hand, ossification of these adenomas is an extremely rare finding, with only one reported case, a prolactinoma. Here, we report a case of somatotropinoma in a 42-year-old acromegalic female.

A case of bronchial adenoma is reported which presented radiologically as an extensively calcified hilar mass on a routine chest radiograph of a patient undergoing surgery for varicose veins. This is of interest because, although bronchial adenomas may present in this way (Zellos, 1962; Baldwin and Grimes, 1967), calcification is not regarded as one of
