We report a case of sinolith in the left ethmoid sinus of a 61-year-old man. The patient complained of nasal obstruction. Computed tomography revealed a small, calcified mass associated with a nasal polyp in the left ethmoid sinus. The antrolith and polyp were removed via endoscopic sinus surgery. Histopathological analysis of the antrolith revealed it

Carcinoma of the ethmoid sinus
American Journal of Otolaryngology, 1986Cancer of the ethmoid sinus is a rare tumor in the head and neck, accounting for less than 1 per cent of all such malignancies.

International Journal of Pediatric Otorhinolaryngology, 1985
A 15-year-old female was evaluated for pain in the region of the right medial canthus and increasing exophthalmos. She had been diagnosed as having pseudo-tumor of the right orbit when she was 8 years old. The diagnosis was sustained until a second ophthalmologist requested a CT scan which demonstrated a mucocele of the right ethmoid sinus.

Osteogenic sarcoma of the ethmoid sinus
The Journal of Laryngology & Otology, 1988AbstractA case of osteogenic sarcoma of the ethmoid sinus is reported in a 45 year old man. The tumour extended superiorly through the frontal sinus and involved the medial wall of the left orbit causing diplopia. Treatment comprised partial excision followed by radiotherapy and chemotherapy with symptomatic improvement, although 13 months later the ...

Neuroendocrine carcinoma of the ethmoid sinus
European Archives of Oto-Rhino-Laryngology, 1994The paranasal sinuses are a rare site for neuroendocrine carcinoma (NEC). In contrast to the other regions, NEC of the sinuses has been reported to be recurrent and locally destructive. We report a case of NEC of the ethmoid sinuses. The patient was a 16-year-old Indian boy and was treated with radiation therapy to 6500 rad.

Fibrous Dysplasia of The Ethmoid Sinus
Otolaryngology–Head and Neck Surgery, 1980Fibrous dysplasia of bones comprising the paranasal sinuses is well recognized. Depending on the anatomic areas of the skull involved by this neoplasm, a combined approach for surgical removal may be necessitated. A case of a patient with fibrous dysplasia of the ethmoid sinus, possibly the first reported case of such change in the ethmoid bone itself,

Cementifying fibroma of the ethmoidal sinus
The Journal of Laryngology & Otology, 1984An interesting case of cementifying fibroma of the ethmoidal sinus is presented. This benign tumour, in this unusual site, tends to behave in an aggressive manner and radical surgery is necessary. Recurrence is frequent.
