This webinar is a brief overview of the types of dermatology cases that are appropriate for biopsy submission, and the methods for taking skin biopsies for histopathology, with specific reference to alopecia cases. A brief description on how to differentiate inflammatory and non-inflammatory causes of alopecia is given and where biopsy might fit into the work up for these different causes of alopecia. There is guidance on biopsy submission to the laboratory and a summary of information needed by pathologists to make the most of skin samples. This is followed up with a case example where biopsy was the final step of the work-up for a patient. This webinar is provided by BSAVA Education Partner IDEXX. A collection of IDEXX ‘topic of the month’ webinars is available here.
