Fisher et al reported an algorithm for managing a patient with a fatty neoplasm that may be an atypical lipoma. The authors are from Winship Cancer Institute and Emory University.
Patient selection: fatty neoplasm and no previous history of sarcoma
Parameters for deciding if lesion significant from current study:
(1) age in years
(2) diameter of tumor in cm
(3) early operation at the same site (previous mass at same site) = recurrent lesion
(4) location (extremity vs torso)

Additional reasons to suspect that the lesion is significant:
(1) imaging findings are suspicious for neoplasm (nodularity, sepatations, variation in fat composition)
(2) there are other reasons to suspect neoplasm
Management factors:
(1) likelihood of significant pathology
(2) comfort with performing an oncologic resection
