TLDR Follicular dystrophy in immunocompromised patients may be linked to medication or viral factors and can improve with treatment changes.
Two case reports from 2004 described similar conditions in immunocompromised patients, characterized by follicular papules, loss of eyebrows and eyelashes, and distinctive histological features. One case involved a kidney transplant patient with "cyclosporine-induced follicular dystrophy," which improved after discontinuing cyclosporine. The other case, termed "viral-associated trichodysplasia," involved viral-like particles and showed some improvement with topical cidofovir. Both cases shared histological findings, suggesting a potential unification under a single entity in future studies.
