In the 2nd PDF, if you check ( table-1 data for group-1) there are 2 patients with penile pmma injections ; they have mentioned both of these patients developed penile skin necrosis - Fournier\'s syndrome (Fournier\'s gangrene) . So what is Fournier\'s syndrome ??
It is a rare severe infection of the genitalia --> severe pain --> redness --> necrosis of the tissues --> Gangrene (penis,scrotum, perineum and abdominal wall) within hours --> high mortality rate.
It is a severe bacterial infection spreads quickly from the urinary tract or the perianal, abdominal, or retroperitoneal areas, often following trauma even a minor trauma e.g. foreskin abrasion , insect bites , circumcision , burns or even masturbation .The gangrene is due to thrombosis of small blood vessels below the skin.
So it is a severe infection adjacent to a portal of entry is the inciting event in the development of necrotizing infection --> Fournier\'s gangrene .
This necrotizing infection (Fournier\'s syndrome) can happen not only in men but also in women and children .

- Foreskin abrasion :-

- In children e.g. :- post circumcision, diaper rash and hot water burn :-

- Here are the list of the etiology of this Fournier\'s gangrene in men, women and children :-

So IMO these 2 pictures in the 2nd PDF are due to severe infection and not due to pmma emboli which can also happen (as they have mentioned Fournier\'s syndrome in table 1 in their article trauma to the skin --> severe bacterial infection --> thrombosis of small blood vessels under the skin --> necrotizing fasciitis --> necrosis of the skin and underneath tissues --> gangrene .
