RESUMEN
Objectives. To investigate hemangiomas in the differential diagnosis of the nasal cavity neoplasms, even though it is an extremely rare mesenchymal tumor of the nasal cavity, and the world literature was reviewed. Case Report. A 57-year-old woman applied to our department with a 5-year history of left-sided nasal obstruction without history of epistaxis, nasal packaging, or facial trauma. Anterior rhinoscopic examination revealed a mass originating from inferior turbinate that completely obstructs the left nasal cavity. Paranasal computed tomography (CT) showed that the bony mass originated from the anterior part of the left inferior turbinate. Surrounding tissues were normal, and there was not any erosion or destruction. Mass was excised by the endoscopic approach. Histological diagnosis was reported as osseous cavernous hemangioma. Conclusion. Hemangiomas are a rare cause of intranasal masses. Its unusual site and masked presentation makes the differential diagnosis difficult. When a bony hard, well-shaped mass was seen in the nasal cavity, the possibility of intraosseous hemangioma must be remembered.
RESUMEN
It is widely accepted that tumoral invasion of the pre-epiglottic space (PES) has a significant prognostic importance in supraglottic laryngeal carcinomas. The lymphatics of the supraglottic larynx drain to cervical lymph nodes via the PES. Since the supraglottic larynx is an embryological unit that contains the PES, malignant lesions of this region must be resected with en bloc surgery, including the PES. Tumors with PES invasion are already considered to be T3 in TNM staging. The purpose of this study was to review the clinical experience we have had with these tumors at Ankara University. The study comprised 150 patients with squamous cell carcinomas of the supraglottic larynx treated with either partial or total laryngectomies. Findings suggested that PES invasion occurred at early stages of supraglottic tumor progression. Suprahyoid epiglottic lesions behaved less aggressively than tumors originating from other supraglottic subsites and did not invade the PES until advanced stages. PES invasion was not considered to be a significant prognostic factor because the majority of the supraglottic lesions studied demonstrated PES invasion regardless of cervical lymph node metastases. Analysis of oncological and functional results revealed that en bloc resection of the supraglottis with the PES was facilitated by preservation of the hyoid bone.

Toxoplasmosis is a protozoan infection manifested by systemic findings as well as generalized or localized lymphadenopathy. Although lympadenitis is the most common clinical form, involvement of the intraglandular nodes within the parotid gland found is a rare occurrence during the course of the disease. This unusual form may mimic a parotid mass, and can cause difficulties in differential diagnosis. In this article, a case of intraglandular parotid lymphadenitis which developed due to toxoplasmosis is presented, and the relevant literature is reviewed.
