Serpiginous gangrene of the skin in a mental patient

In 1897, I had to observe a case of serpiginous gangrene of the skin in a mentally ill patient in the House of Appreciation of the mentally ill Emperor Alexander III. This case, it seems to me, is of sufficient interest both in the meaning of the vastness of the defeat and the nature of the course, as well as in the meaning of ethology, which is why I consider it unnecessary to describe it.
