Oncocytic carcinoma of the nasal cavity with widespread lymph node metastases.

The first case of oncocytic carcinoma which arose from the inferior turbinate of the nasal cavity with orbital invasion through the nasolacrimal canal and widespread lymph node metastases in the neck and face is reported here. The tumor metastasized rapidly, spread widely to the whole neck and face, and produced tumor emboli in the lymphatics and extranodal extension by rupture of the lymph node capsule in the absence of clinically palpable regional lymph node enlargement. We think the oncocytic carcinoma of the nasal cavity may be a high-grade malignancy tumor.

Solitary fibrous tumor arising in the sphenoethmoidal recess: a case report and review of the literature.

Recently, solitary fibrous tumors (SFTs) have been reported in the head and neck area, such as the nasal cavity, thyroid, salivary gland, etc. We present a rare case of SFT which arose from the sphenoethmoidal recess of the nasal cavity, penetrating into the sphenoid sinus, and which showed different intensities on magnetic resonance imaging (MRI) according to the occupied locations. T2 weighted magnetic resonance (MR) images showed low intensity in the nasal cavity, and iso-intensity in the sphenoid sinus.
