Chemodectoma (non-chromaffin paraganglioma) of the ninth intercostal space.


In a 30-year-old man, radiography revealed a mass in relation to the ninth left intercostal space (Fig. 1). There was no radiological increase in the size of the mass one year later when operation was undertaken. At operation a sessile mass was removed from the ninth left intercostal space posteriorly, in the position usually occupied by a neurofibroma. The tumour was thought to arise from the intercostal nerve or the sympathetic chain, though there was no obvious connexion with either. Ten months after operation, the patient was well, without clinical or radiological evidence of recurrence. The specimen consists of an encapsulated oval tumour mass, without lobulation, measuring 10 mm. x 5 mm. (Fig. 2). The cut surface is light yellow and has a spongy texture. Histologically it shows the basic structure of a carotid body tumour. It consists of nests of pale " epithelioid " type cells surrounded by a vascular stroma. Many of the nuclei of the pale or " chief cells " are hyperchromatic and occasional multinucleated forms are
