Liomyomas of the nasal cavity and paranasal sinuses are rare. They make up less than 1% of all leiomyomas in the human body. This is due to the paucity of smooth muscle in the nose. They are classified in three groups: leiomyoma, angiomyoma and epithelioid leiomyoma. Only 15 cases of vascular leiomyomas have been found in the literature. The treatment of choice is surgical excision. Hereby we present a new case and review the literature.
Non-Hodgkin S lymph oma of the sinonasal tract is an uncommon lesion, representing 1.5 to 15% of all lymphomas. Mos t cases ofprimary non-Hodgkin 's lymphoma of the sinonasa l tract occur in the maxillary sinus, ethmoid sinus, and nasal cavity; its occ urrence in the fro ntal sinus is extremely rare. We report a case of primary type B non-Hodgkin 's lymphoma of the frontal sinus in a 43-y ear-old man. The patient complained of f rontal headaches that had not improved with analgesic drugs, and he presented with afrontal bulge that involved the left upp er eyelid; the bulge had p rogressively enlarged over a 3-month period. A biopsy ofthe mass identified the typ e B non-Hodgkin 's lymphoma. Immunohistochemical study not only confi rmed the histologic type ofthe tumor; it also provided some important information about the primary tumor site. Advances in immun ohisto chemistry have shown that type B non-Hodgkin 's lymphoma is more common in North American and European patients, whereas subtype T is more comm on in Asians and in some Latin Americans. The treatment of this condition is still controversi al, but the combination ofradiotherapy and chemotherapy has yie lded the best resul ts in all stages of the disease.
In our experience, endoscopic decompression of the lamina papyracea shows complete recovery of extrinsic ocular motility in these patients and should be combined with intravenous antibiotic therapy.
Ringer's lactate at the concentration of 6.0mg/g was superior to that at 4.5mg/g for parameters comfort and stinging sensation. No statistical difference was observed between the two products regarding nasal humidification.
