piecemeal excision
Pronunciation: PEES-meal ek-SIZH-un
Removal of a tumor in multiple fragments rather than as a single intact specimen, generally avoided in oncologic surgery.
Full Definition
Piecemeal excision refers to the surgical removal of a tumor or lesion in multiple separate pieces rather than as an intact specimen. This approach is generally discouraged in oncologic surgery because it compromises histopathologic evaluation, makes margin assessment impossible, and may increase the risk of tumor spillage and local recurrence. However, piecemeal excision may be unavoidable in certain anatomically constrained locations or when tumor size prohibits en bloc removal. When performed, meticulous documentation of the excision pattern and specimen orientation is essential.
Usage
Usage note: Generally indicates suboptimal oncologic technique; should be justified when documented.
