*Slowly expanding non-neoplastic mass of horses
*Originates from submucosa of ethmoidal labyrinth
*Either from nasal or sinusal portion of ethmoid labyrinth
*Unilateral, can extend to nostrils or choanae
*Rarely elsewhere in sinuses
*Expands to nasal cavity, [[Paranasal Sinuses Hyperplastic and Neoplastic - Pathology|paranasal sinuses]], [[Nasopharynx Hyperplastic and Neoplastic - Pathology|nasopharynx]] causing destruction of tissue
*Micro - haemorrhage, calcification of connective tissue fibres
*[[Aspergillus spp.|''Aspergillus'' spp.]] may be present on the lesion
*May cause [[Respiratory System Clinical Signs - Pathology#Epistaxis|epistaxis]]
*Can recur after surgical excision
*May arise subsequently to [[Rhinitis#Chronic rhinitis|chronic inflammation]]
