- Most bone tumors present as well-defined osteolytic lesions, sometimes referred to as 'bubbly lesions'.
-It is important to have a good differential diagnostic approach to these lesions.
-You can use the table above, but another way to look at the differential diagnosis of well defined osteolytic bone lesions is to use the mnemonic Fegnomashic, which is popularized by Clyde Helms (1).
-Some prefer to use the mnemonic Fogmachines, which is formed by the same letters, but is a real word.
