Solitary fibrous tumour of the laterocervical spaces.

Solitary fibrous tumours are rare mesenchymal neoplasms usually arising in the pleura. Extra-pleural locations are uncommon although some cases of head and neck involvement have been reported in the recent literature. In such cases, nose, paranasal cavities and parapharyngeal spaces are the most frequently affected sites. The Authors present a case of a solitary fibrous tumour involving the laterocervical spaces. The histological diagnosis of solitary fibrous tumours gives rise to significant problems since parameters for determining their aggressiveness are still controversial. Immunohistochemical techniques are considered to provide a decisive identification. Follow-up plays a crucial role, as recurrences can occur even after several years. Usually, complete surgical excision is adequate whilst curative and radiochemotherapy may be indicated if complete resection of the tumour mass is impossible.
