Dear Editor, A 27-year-old woman was referred to our clinic for the consultation of multiple halo nevi. She had been diagnosed with Turner syndrome with a karyotype of 46,X,i(X)(q10) when she was 9 years old. She received growth hormone treatment from 9 to 16 years of age and progesterone and estradiol patches since 15 years of age. Three months before she visited our clinic, she noticed a white macule around a pigment spot that had existed since her childhood on her right forearm. The white macule gradually enlarged, after which she noticed that white macules had appeared around other pigmented spots distributed throughout the body. When she visited our clinic, we observed 11 halo nevi: one on the left lower jaw, one on the left neck, one on the upper back, one on the right forearm, one on the right upper arm, one on the right knee, three on the left thigh and two on the left lower leg (Fig. 1a-e).
