RESUMEN
Rhinolith is an uncommon nasal mass and a rare entity encountered in clinical practice. The typical symptoms of rhinolith are unilateral nasal obstruction, foul smelling purulent nasal discharge and epistaxis, crusting, swelling of nose or face, anosmia, epiphora and headache. In this report, we present a case of recurrent rhinolith manifesting as an incidental finding on dental radiographs. A 26-year old male patient with a history of long standing halitosis had an operation for rhinolith seven years previously. Rhinolith in the right nasal cavity was diagnosed on rigid endoscopic examination. Rhinolith was removed by using a rigid nasal endoscope under local anaesthesia. To our knowledge, recurrence of rhinolith has not been described previously in the literature.
El rinolito es una masa nasal poco común y una entidad rara en la práctica clínica. Los síntomas comunes del rinolito son: obstrucción nasal unilateral, secreción nasal purulenta y maloliente, epistaxis, encostramiento, inflamación de la nariz o la cara, anosmia, epífora, y dolor de cabeza. Este reporte presenta el caso de un rinolito recurrente, que se presentara como un hallazgo incidental en una radiografía dental. Un paciente varón de 26 años de edad, con una larga historia de consulta por halitosis con un dentista y un otorrinolaringólogo, fue operado a causa de un rinolito hace siete años. El rinolito en la cavidad nasal derecha, fue diagnosticado mediante un examen endoscópico rígido. El rinolito fue extirpado usando un una endoscopia nasal rígida, bajo anestesia local. Hasta donde sabemos, la recurrencia de rinolitos no ha sido descrita previamente en la literatura.

Epididymal lithiasis is a dysfunction characterized by formation of calcium-rich stones in the epididymal region of roosters, associated with decreased serum testosterone and loss of fertility. The segment most affected by the lithiasis is the efferent ductules, which, in birds, are responsible for reabsorption of calcium and luminal fluid. Therefore, we postulated that epididymal lithiasis could result from local impairment of calcium or fluid homeostasis, culminating in initiation of stone formation. Transepithelial calcium transport depends on vitamin D3 and vitamin D3 receptor (VDR). Based on the fact that VDR are present in efferent ductules, possible changes in the pattern of VDR in roosters affected by the epididymal lithiasis was investigated, to start to gain an understanding of the molecular mechanisms involved in the development of calcium stones. To evaluate the potential impact of androgen reduction, changes in androgen receptor (AR) were also investigated. Both VDR and AR were increased in specific segments of the epididymal region, whereas no alterations were found in the testes of affected animals. The increase in VDR was most likely due to an increase in the number of VDR-positive mononuclear leukocyte infiltrates found in the connective tissue followed by an increase in epithelial receptors. The AR were increased, however, mainly in the epididymal duct epithelium. These results suggest that the vitamin D3 and androgen responsive system may be directly/indirectly involved in the development of the disease.
