Explain why Munchausen's syndrome is considered a variant of pseudologia fantastica rather than a wholly separate diagnosis.

Munchausen's syndrome shares the core features of pseudologia fantastica: fluent, elaborate, and apparently genuinely absorbed fabrication, occurring without underlying organic brain disease, with an eventual admission of the truth when confronted with clear, incontrovertible evidence. What sets it apart is not a different underlying process but a narrower, specific target for the fabrication — illness and repeated engagement with medical services, rather than false claims more broadly. Recognising it as a variant rather than a separate category matters clinically, since it links the presentation to the same underlying pattern of fluent, absorbed fabrication seen in pseudologia fantastica more generally, while still flagging the distinct forensic and healthcare-resource implications of a presentation built specifically around fabricated illness — including, in its proxy form, direct harm to another person rather than self-directed fabrication.
