===Tumour in tip - flipped block=== | |||

Lesion, Right Lower Eyelid, Excision: | |||
- BASAL CELL CARCINOMA (BCC), favour positive margin, see comment. | |||
Comment: | |||
BCC was found in block 1 (one of the tips) on the initial cut. | |||
In block 1, BCC is present but distant from the inked margin in the plane | |||
of section. The margin is not completely in the plane of section; thus, | |||
trimming of a negative margin cannot be entirely excluded. As BCC is seen | |||
on both sides of the block, a positive margin is favoured. | |||
