Marking sutures to orientate specimens of basal cell carcinoma: do they really make a difference?

Traditionally, marking sutures have been used to orientate specimens of non-melanomatous skin cancers, and they provide an identifiable point as a reference for monitoring and further treatment. For histopathological purposes, the orientated specimen is marked with different inks, which enables measurement to the nearest lateral and deep margins, and if invaded, guides further excision. We retrospectively analysed 688 specimens of basal cell carcinoma (BCC) from the head and neck from two separate years: 2010 and 2012.
