In situ i-ALCLs have an indolent clinical course and generally remain free of disease after implant removal. However, infiltrative i-ALCLs could have a more aggressive clinical course that might require additional therapy to implant removal.

Optimal surgery should be performed, but pneumonectomy should be avoided whenever possible. Adjuvant treatment is suggested to provide an added survival advantage.
