- 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, nasopharynx causing destruction of tissue
- Micro - haemorrhage, calcification of connective tissue fibres
- Aspergillus spp. may be present on the lesion
- May cause epistaxis
- Can recur after surgical excision
- May arise subsequently to chronic inflammation
