What Is This Pimple in My Recipient Area — Infection, Lost Graft, or Something Else?

I had a transplant almost 4 weeks ago, and last night, I had a pimple start to bleed in the transplanted area, without having touched it at all. Is this a sign of an infection, lost graft, or something that just happens, thank you

It is very difficult to make such a determination without examining you. Based on my experience, this sounds like an epidermal inclusion cyst, which refers to a cyst that develops as a result of the implantation of epidermal elements (i.e., hair follicle) in the dermis. If this is the case, it is not an infection. However, another more serious process (such as folliculitis) can be the culprit. This too can develop after a hair transplant procedure and with this, patients typically require antibiotics along with possibly “opening” up the infected areas to remove underlying infected material (pus). Whatever the cause in your case, make sure to follow up with your transplant doctor.
