is there a clinical name for someone that enjoys burning themselves with lighters or cigarettes?

Self-injury is a symptom of many different disorders.

Borderline Personality Disorder is one such diagnosis which often features the symptom of self-injurious behavior.

A pyromaniac or something like that is someone who's fascinated with started fires for no reason (other than being disturbed).

Don't know if there's a clinical name for burning oneself.

If someone's really hurting themselves, I'd think that they're dealing more with Bipolar disorder... but not everyone can be categorized easily.
