Should I See a Plastic Surgeon or an Orthopedic Doctor for Injection Treatment of Lipoma in Wrist?

I had what was believed to be a ganglion cyst removed from my wrist and the area cleaned up arthroscopically 3 years ago, it turned out to be a lipoma instead (I'm well aware this is rare and I know for a fact it wasn't a cyst I have the pathology report), over the past year and a half the lesion has returned. In such a small space the excision left enough for it to recur, I'd like to try a noninvasive approach (the process took a year to recover from last time) but don't know who to ask.
