Soon after the case of the fake doctor Oneal Ron Morris was busted, a series of cases involving doctors apparently practicing illegal cosmetic plastic surgeries have come to light.

The latest is that of a woman doctor, who injected a 22-year-old man's penis with silicone during a so-called pumping party, killing him. The police arrested her on Friday, the Daily Mail reported.

A pumping party is an illegal, growing underground movement, a gathering where transgender individuals inject silicone into their bodies to create curves, breasts, hips, etc. These parties are sometimes attended by non-transgender individuals too, who are looking for a low-cost solution to the desired cosmetic procedures. These procedures are performed by non-professionals in unsanitary conditions (www.urbandictionary.com).

This incident took place on May 5 this year when the victim, Justin Street, visited Kasia Rivera, 34, at her home in New Jersey for a penis enhancement procedure, say the prosecutors.

The day after the pumping party, Street suffered a clot to the lungs and died. According to doctors, the death occurred due to silicone embolism, and Rivera has been charged with manslaughter.

Rivera has also been charged with illegal practice of medicine and was arrested on Friday. She is being held on a $75,000 bail.

Using silicone injections to enlarge body parts has become common practice of late. Since the procedure is expensive, a lot of people go for cheaper options and, consequently, fall into the trap of unlicensed practitioners.

While side effects of silicone are rare, if it happens to leak into the blood stream, it can cause fatal clots in the heart, brain or lungs. It can also migrate through tissues, causing disfiguring lumps, says the report.

A fake surgeon was arrested for carrying out a DIY surgery on at least five people in Florida, last month. Oneal Ron Morris, 30, allegedly injected her patients with deadly toxins including cement, mineral oil and tyre sealants, before sealing the wounds with superglue.

Last week, Lauretta Cheek, 42, was arrested for allegedly injecting dangerous solutions into the buttocks of an exotic dancer from Charlotte, who wanted them bigger.
