Blocks for Histology

The histology should represent the deepest extent of the tumour, the relationship to the cutaneous, mucosal and deep soft tissue margins and changes in adjacent vermilion border mucosa and skin (Figure 13.5).

• at least one block of tumour per centimetre of maximum dimension.

• if lateral shave excisions of vermilion border are present, take one block from the cutaneous to mucosal aspects at the junction with the wedge and one transverse block of the lateral limit of each shave. If greater than 2 cm in length, take one additional block for every centimetre.

• cutaneous, mucosal and deep surgical margins.

• samples of other lesions not already represented, e.g., mucosal white areas or ulcers.
