title: [Report on a methemoglobin-associated fatality].
abstract: An autoerotic fatality due to mechanical compression of the neck by a sophisticated construction used for breath control games is reported. The presence of signs of methemoglobinemia as well as an empty "poppers" flask found beside the passed indicated the use of volatile nitrites to enhance sexual pleasure. It was assumed that vasodilatation had caused a sudden unconsciousness with consecutive hanging.
