| |
| − |
| |
| − | ====Gross====
| |
| − |
| |
| − | * Encysted larvae appear as pinhead grey to red mucosal nodules.
| |
| − | * Mass emergence results in:
| |
| − | ** Mucosal erosions.
| |
| − | * Ulcers.
| |
| − | * Fibrinous exudates.
| |
| − | * Haemorrhage.
| |
| − |
| |
| − | ====Histopathology====
| |
| − |
| |
| − | * Larvae in deep mucosa/sumucosa surrounded by fibrous capsule and mixed inflammatory cells.
| |
| − | * Intense eosinophil, neutrophil and macrophage infiltration when larvae emerge
| |
| − | ** May also be oedema and, if severe, mucosal ulceration.
