Based on the published literature of the past 10 years, this is a review concerning the topic of HIV-spectrum pathology and suicidality from a markedly suicidological point of view. HIV infection is considered as a possible suicide risk factor among several other ones involved. We distinguish between research on complete suicide, attempted suicide, DSH, and suicidal thoughts. We have analytically examined the overlapping of the complex area of HIV-infectious pathology and of the heterogenous area of suicide behaviour: a unifying picture may be achieved by introducing the concept of 'mosaicism'.
