  • Abstract
  • Look Inside

 A rhinolith in the right inferior nasal meatus of a 23-year-old female with recurrent nose bleeding in the left nose was reported. The rhinolith, extracted with a forceps, was bended oval in shape, 1.05 g in weight, and 19.4, 13.4 and 8.0 mm in length. The covex surface exposed in the nasal cavity was gray-green and the rugged surface adjacent to the nasal meatus was gray-hrnown.

 The specimen was investigated by means of decalcified sections, contact-microradiography, scanning electron microscopy and x-ray micro-analysis. The rhinolith possessed the porous core based on a globular mass of cotton fibers where Ca, P, Mg, Na and S were detected. The main constituent crystals were haxahedaral forms, probably, Mg-whitolckite. The outer layer, partially laminate structures, was formed by the both extra-or intermi crobial calcified deposits which contained higher concentrations of Ca and P. It seemed that the main constituent crystals were hydroxyapatite. The outer surfaces with thin organic layers were amorphous.

 On the above mentioned observations the origin of this rhinolith was discussed.
