A user's guide to veterinary surgical pathology laboratories. Or, why do I still get a diagnosis of chronic dermatitis even when I take a perfect biopsy?
During the past decade, clinicians have come to rely more heavily on veterinary surgical pathology services to provide assistance in the diagnosis of inflammatory and neoplastic skin disease. To obtain maximum results from each skin biopsy, it is important that clinicians have a good understanding of the factors that can affect histologic evaluation after the biopsy specimen has been removed from the patient. This article discusses the role proper tissue fixation, trimming, and grooming can play in obtaining an accurate histologic evaluation. The importance of understanding the limits of dermatopathology in establishing a definitive diagnosis of many inflammatory and neoplastic skin diseases is emphasized.
