Carcinoma of the Ethmoid Sinus

Thrombotic Microangiopathy Revealing Bone Metastases from an Ethmoid Sinus Carcinoma

Cancer-related thrombotic microangiopathy (TMA) is a rare entity whose clinical and biological characteristics have been described in various tumors. Here we describe the first case of cancer-related TMA revealing diffuse bone metastases from an ethmoid sinus carcinoma.

Tooth in Ethmoid Sinus: A Case Report

Ectopic eruption of teeth occurs in a variety of locations. Commonly seen in palate and maxillary sinus, they have also been reported in nasal cavity, orbit, mandibular condyle, coronoid process, and facial skin.Here, we report a rare case of recurrent sinusitis caused by ectopic tooth in right ethmoid sinus and successful endoscopic removal of it.

Fibrous dysplasia of the ethmoid sinus.

Although craniofacial bone is the second common site of fibrous dysplasia involvement, it is rarely found in the paranasal sinus. Among fibrous dysplasia of the head and neck, the maxilla and mandible are the most frequent sites to be involved. Fibrous dysplasia becomes dormant in adolescence and early adult life and is more common in female. It is one of the fibrous osseous lesions and should ...

Primary chordoma of the ethmoid sinus.

Primary chordoma of the paranasal sinuses are extremely rare tumours, with only a small number of cases verified and published in the literature. It appears that only five of these cases involved the ethmoid sinuses either as a primary or by local invasion, and of these documented cases only one other has been found to solely involve the ethmoid sinus. We present a case of primary ethmoid sinus...
