There is a huge variety of soft tissue tumours. By combination of different kinds of tissues development of rare tumours is possible. Mesenchymal tumours consisting of lipoid, chondroid and myxoid tissue – chondromyxolipoma – are rarely described in literature.
We want to report on a case of an not yet described paraphayngeal chondromyxolipoma. In a 66-year-old woman without any symptoms a parapharyngeal tumour caudal of the base of the skull was detected by MRI scan. Clinically, a circumscribed, yellow swelling in front of the right auditive tube with intact mucosa was found. CT scan showed a circumscribed lesion of 2 x 3 x 3,5 cm in diameter in the right pterygopalatine fossa without signs of invasion. Density was similar to fat tissue. The tumour was supposed to be benign with fluid-like inner structures.
As the patient was free of symptoms and because of the difficult anatomic position a transcervical approach was chosen. Histology proved a benign mesenchymal mixed tumour formed of chondroid, myxoid and lipoid parts – a chondromyxolipoma.
Retrospectively, in this case a conservative resection of this not yet described tumour was possible despite difficult anatomic conditions and the dignity of the tumour could be defined.
