TMZ: One of the doctors featured on the reality show "Dr. 90210" is being sued by a former patient who claims some very "personal" body parts were damaged during a procedure at the doc's Laser Vaginal Rejuvenation Institute of Los Angeles.

According to a lawsuit filed today in L.A. County Superior Court, Dr. David Matlock is being accused of causing Patricia D'Edgido to suffer "extreme and severe permanent personal injuries" after a 2007 surgery "on her buttocks and other areas of her body, including her arms and vaginal area."

Among the allegations in the lawsuit, Patricia accuses the doc and the institute he founded of "the use of an improper surgical technique, the artless execution of surgical technique, including the manner in which defendants performed such surgery ... failure to perform the correct surgical technique."

Now Patricia is looking to snatch more than $25k for her troubles.

Calls to Dr. Matlock's peeps have not yet been returned.
