A doctor made an unnecessary internal examination of a female patient's private parts without the presence of a nurse and secretly photographed them, a court heard yesterday. The woman was so embarrassed during the examination by dermatologist Christopher Tong Yung-man, 31, that she covered her eyes with her hands, Sha Tin Court was told. Tong denied indecently assaulting the 32-year-old woman, who had gone to him because of a rash around her groin on July 13, 2008. Prosecutor Keith Hotten said the vaginal examination was unnecessary and unwarranted for the victim's condition. Hotten said the case came to light after police acted on a complaint and searched GHC Medical in Tai Wai Road, Tai Wai, where Tong worked, and his home. On his computer they found 16 obscene photos, including four showing the genitals of the woman whom police identified by matching the date the photos were taken with patients' records. Hotten said the woman had gone to Tong's clinic for a consultation because of red lumps on her groin that gave her a prickly pain. Tong first asked her to pull her trousers down to her knees for an examination with her underwear on but then later said he wanted to look at her private parts, he said. The woman told the court she had at first pretended to not hear what Tong said but gave in after the doctor's repeated requests. 'He asked me whether I felt any pain ... three to five times. I said I didn't,' she said. 'I covered my eyes with my hands because I felt embarrassed. I dared not look at him,' the woman said. She said she had been puzzled, confused and embarrassed, adding that she had not asked any questions or resisted because it had not occurred to her. The doctor told her that her condition was infectious and asked her to abstain from sex. She said she was not aware that Tong had taken photos of her private parts, and agreed that he had not expressly asked her prior consent. Gerard McCoy SC, representing Tong, said it was not in dispute that the photos were of the victim. McCoy suggested that Tong had told the victim he had to examine her private parts because they were infected but the victim said she could not recall such words. The victim consulted two female doctors, one before Tong and one after, neither of whom asked her to remove her underwear or inspected her private parts. Dr Kitty Wong Kwok, who inspected the victim three days before Tong, said it was normal practice that a doctor would examine a patient's private parts in the presence of a nurse at her clinic, Lek Yuen Health Centre in Ma On Shan. 'It protects the clinic ... because things could happen,' she said. Dr Cindy Hau Sin-ying, whom the victim consulted on July 27, said diagnosis could be done by inspection of the affected area alone. The case continues before Deputy Magistrate Poon Chin-chiu today.
