Marking margins of tumorectomies and excisional biopsies to facilitate histological assessment of excision completeness.
Assessment of tumor margins for completeness of excision is important for local control of neoplastic masses, particularly those that are potentially curable with surgery. Of the margin-marking techniques available, India inking seems to be the most practical way for veterinary clinicians to help pathologists accurately distinguish between surgical margins and margins created during sample processing. India inking prevents misinterpretation of contaminated processing margins as inadequate surgical excisions; however, a strongly definitive decision that an excision is complete cannot be made with any margin-marking technique because it is impossible to examine the entire surface of every margin.
