A pathologist has come under fire for posting hundreds of gruesome photographs from autopsies online, including pictures of dead fetuses.

Angemi posted this picture of a mangled leg with the caption: 'Everyday is Halloween in Pathology!!!!!!'

Nearly half a million people follow Nicole Angemi's Instagram, which features images of mangled bodies and horrific injuries. Most of the shocking photos were taken by Angemi without permission of the deceased relatives, infuriating people online.

The graphic pictures - many too grisly to be published here - include an adult man having his face slowly torn off during an autopsy, a man who has been fatally stabbed in the head and several miscarried and aborted babies.

Angemi, who works in a hospital in New Jersey, claims she posts the pictures online to educate people, but some people see it as exploiting the dead. See the very graphic pictures after the cut.
