Rhinosporidiosis of the parotid duct.

Yadav SK, Shrestha S - Case Rep Dent (2014)

Bottom Line: The common sites of involvement are the nose and nasopharynx followed by ocular tissue.The case presented here is of 18-year-old male from the nonendemic zone of Nepal with a proliferative mass in the parotid duct.Thus clinicians should be flexible in the differential diagnosis of proliferative growth in the parotid duct, even in those cases which are from nonendemic areas.

ABSTRACT
Rhinosporidiosis is a benign chronic granulomatous infection caused by Rhinosporidiosis seeberi (R. seeberi). Rhinosporidiosis is endemic in South Asia, notably in Southern India and Sri Lanka. The common sites of involvement are the nose and nasopharynx followed by ocular tissue. Rhinosporidiosis is also known to involve many rare sites and may become disseminated to ocular in generalized form. Rhinosporidiosis of parotid duct is extremely rare. The case presented here is of 18-year-old male from the nonendemic zone of Nepal with a proliferative mass in the parotid duct. Although rhinosporidiosis was not taken into consideration in the clinical differential diagnosis, eventual histopathological diagnosis confirmed rhinosporidiosis. Thus clinicians should be flexible in the differential diagnosis of proliferative growth in the parotid duct, even in those cases which are from nonendemic areas.

Mentions: The excised specimen was submitted for histopathologic examination. The hematoxylin-eosin-stained sections showed thin fibrocollagenous cystic wall lined by columnar to cuboidal to flattened cells. One of the parts of the specimen showed the presence of numerous, nonvital sporangia of R. seeberi (Figure 8). Histopathological examination confirmed the diagnosis of rhinosporidiosis of Stensen's duct with secondary infection and dilatation of the duct.
