Which term refers to obsessive self-interest?

The term that best describes obsessive self-interest is egomania. This term emphasizes an intense preoccupation with oneself, often coupled with a lack of regard for others. Individuals exhibiting egomania are typically excessively focused on their own needs, desires, and experiences, leading to behavior that can be seen as self-centered or inflated in regard to their own importance. This level of self-obsession can manifest in various ways, including vanity, an excessive need for admiration, and an unwillingness to consider others' perspectives or feelings.

While egoism and selfishness relate to self-interest, they do not necessarily capture the obsessive and extreme nature of egomania. Narcissism also speaks to a self-focused mindset but is often used within clinical contexts to describe a personality disorder with specific diagnostic criteria. Egomania, however, directly conveys the idea of an obsession with oneself in everyday language.
