Respiratory epithelial adenomatoid (READ) hamartoma is a recently described entity characterized by abnormal glandular formations arising from the epithelium of the nasal cavity. The etiology of the lesion is unclear and may be secondary to either sinonasal inflammation or developmental error. We present a case of a 54-year-old man with a unilateral nasal mass found to be consistent with READ h...

BACKGROUND Nasal polyps are benign lesions originating from the nasal mucosa or paranasal sinuses. The most important etiological factor seems to be increased hydration of epithelium and hyperplasia of the extracellular matrix, which may involve hyaluronan, a high molecular mass extracellular glycosaminoglycan. Degradation of hyaluronan proceeds through the action of specific hyaluronidases. ...

Background: Rhinosporidiosis is a rare chronic granulomatous disease characterized by polypous lesion of the mucous membrane caused by rhinosporidium seeberi which predominantly affects the mucous membrane of the Naso-pharynx, conjuctiva and palate. Rhinosporidiosis can be easily misdiagnosed as a neoplastic disease, and hence, it is necessary to educate the public and medical community about t...

Here, we report an extremely rare case of acquired nasolacrimal duct obstruction caused by oncocytic carcinoma. A 64-year-old man presented to the hospital complaining of epiphora and left-side nasal obstruction. Ophthalmic and otolaryngology examination revealed a left lacrimal duct obstruction caused by a mass in the left nasal cavity and lacrimal drainage system. The mass was removed and con...

INTRODUCTION Nasal polyps are benign prolapsed mucosal lesions which commonly arise from the paranasal sinuses and lateral walls of the nose especially the contact areas of osteomeatal complex. Though nasal polyps arising from the nasal septum have been reported, those arising from its anterior part are extremely rare and present a diagnostic dilemma. Aetiology is multifactorial and is mainly a...

Rhinoliths are uncommon clinical entities reported in clinical practice as unusual cause of unilateral nasal obstruction and foul smell nasal discharge. Rhinolith is calcified material found in the nasal cavity incidentally or due to patient complaint. It should be suspected when patient presents with nasal symptoms and found to have stony mass showed radiologically. We reported a 28-year-old S...

We report the case of a 58-year-old Tunisian man who presented with a 2 months' history of left nasal obstruction and one episode of epistaxis. Nasal endoscopy revealed a polypoid mass of the left nasal septum. Magnetic resonance imaging showed a left nasal cavity tumor with erosion of the orbit. Diagnosis of nasal cavity lymphoepithelial carcinoma EBV positive was performed on biopsy. The pati...

Various types of diseases can involve the nasal vestibule. Diagnosis and treatment of a nasal vestibular mass is often challenging due to the anatomical features of the nasal vestibule. Here, we present four cases with nasal vestibular masses. Two cases were diagnosed as squamous papillomas. The others were a trichofolliculoma and pseudoepitheliomatous hyperplasia with hyperkeratosis. Our aim w...

Nasal polyp is a benign lesion that arises from the mucosa of the nasal sinuses or from the mucosa of the nasal cavity as a macroscopic edematous mass. The exact etiology is still unknown and controversial, but it is assumed that main causes are inflammatory conditions and allergy. It is more common in allergic patients with asthma. Interleukin-5 has found to be significantly raised in nasal po...
