Full Thickness Excision

An intact specimen preserves the lesion together with its surrounding tissue relationships, allowing histopathological examination of the abnormal area as a whole. This helps assess tissue depth, margins, and the extent of disease rather than relying only on a small or fragmented sample. The findings can therefore provide a more complete basis for evaluating suspicious lesions or selected skin tumors.

Including the epidermis, dermis, and underlying subcutaneous tissue allows examination across the lesion’s full vertical extent. That depth is important when disease may extend beyond the visible surface. By retaining deeper tissue in the specimen, the procedure supports assessment of how far the abnormality reaches and whether the sampled tissue adequately represents its extent.

Margins show the relationship between the removed abnormal tissue and the edges of the specimen. Histopathological assessment of these edges can help evaluate whether disease extends to the boundary and contributes to judging the completeness of removal. Margin information is especially relevant when clinicians assess suspicious lesions or selected skin tumors for their extent.

The surgeon first identifies the target and makes an incision around it. The lesion is then separated from surrounding structures so that it can be removed as an intact specimen containing the relevant tissue depth. After removal, the resulting wound is assessed for repair, with direct closure, a graft, or a flap used as appropriate to the defect.

This approach may be selected when evaluating a suspicious lesion, a selected skin tumor, or another abnormality for which depth and disease extent matter. Removing tissue through the involved layers provides more information than examining only the surface. Its use therefore supports both lesion management and pathological assessment when a deeper, intact specimen is needed.

Once the lesion has been removed, the wound may be closed directly if the surrounding tissue permits. When direct closure is unsuitable, reconstruction can use a skin graft or flap. The available repair options relate to the size and resulting nature of the defect, while the excised tissue remains available for histopathological assessment.
