The trachea is an unusual site for paragangliomas, only four cases having been documented previously. A fifth case is presented here, together with immunohistochemical evidence that the tumour is biologically benign.

The histological and clinical features of a primary chemodectoma arising in the orbit are described. It is suggested that the tumour may have arisen from chemoreceptor tissue in the area of the lacrimal gland.

Extra-adrenal myelolipomas are rare, generally solitary, non-functioning tumors consisting of adipose tissue and hematopoetic elements. These lesions are not known to be associated with underlying hematologic disorders or documented bone marrow abnormalities. We describe the extremely rare occurrence of multifocal, extra-adrenal myelolipomas in a 35-yr-old male. A markedly hypocellular bone mar...

Extra-adrenal myelolipoma is a rare benign tumor which can occur in the abdomen, thorax, or even in the face. We present a case of 58-year-old woman patient with thoracic myelolipoma, which has manifested as three paravertebral masses at the level of T9 and T10. The computed tomography scan showed heterogenous enhancing masses, which contained fat component. She underwent video-assisted thoraco...
