Solitary fibrous tumours are uncommon spindle cell neoplasms generally associated with serosal surfaces, especially the pleura (‘localized fibrous mesothelioma’). Recently, these tumours have been documented in extraserosal sites. We report two solitary fibrous tumours, including one occurring in the paediatric age group, arising in two previously unreported locations, parapharyngeal space and epiglottis. These cases expand the range of sites where this tumour may originate and confirm the tendency of extrapleural cases to involve the upper respiratory tract and adjacent structures.

Hibernoma is a benign tumour, arising from vestigial remnants of brown adipose cells, which have persisted from embryonic life. Although it is a well recognized entity, it is an extremely rare tumour. Recent reports estimate 81 cases in the world literature, only seven being in the neck. To our knowledge, it has never been reported in the parotid region. We report such a case and discuss the historical background of a hibernoma, along with its pathological and clinical behaviour.
