Using our state-of-the-art microwave processing system, our histology department can provide same day results for most fixed tissue specimens.
In general terms, equine lesions are best sampled, if possible and appropriate, by total removal and submission for histopathological processing and examination. If total removal is not possible, samples of representative size and location should be collected by wedge resection. Fine needle aspirates should only be collected if it is not possible to collect larger samples.
Removed lesions or biopsies should be placed immediately into an adequate volume (10 x sample volume) of 10% formol saline. Reproductive tissues are best fixed in Bouin’s fluid because of their higher water content. Large lesions should be sectioned before submersion to allow adequate penetration of fixative. Sectioning should be performed with a thought to how the sample will need to be trimmed and orientated for histopathological processing to allow the pathologist to make a complete and meaningful appraisal.
We recommend that organ and tissue samples are taken from adjacent, grossly normal sites as well as from lesional sites. Notes of your own post-mortem examination findings should be sent to aid histopathological interpretations.
Samples should be carefully packed for transport to avoid leakages and breakages.
