Pseudolymphomatous Folliculitis & Focal Dystropic Calcification

Dear Docs,
I would like to know how to treat the title mentioned case. It was on the left cheek for a month. At the beginning the dermatologist diagnosed it was a sebaceous cyst, then steroid was injected onto the swelling area & took Zinnat 500mg 2 times daily for 1 week but it doesnt have any improvement and the cyst kept enlarge day by day. Finally, the case was transferred to plastic surgery. A cyst was took out 10 days ago by plastic surgery doc. Refer to the patho report it was psedolymphomatous folliculitis and focal dystrophic calcification. 14 stitches was removed today but feels very itchy and swelling on the affected area. Doc said that may be need steroid treatment (inj & oral)after one or two weeks if there is no any improvement. I need a second opinions from the docs and I dont know what the next I should do. Thank you very much for your opinions.
