A 42 year old Hispanic American woman had two nodules on her scalp for more than ten years. The nodules slowly grew larger and lost their hair. Her father had these types of nodules as well. The size of the nodules on the scalp were (a) 1.3 × 1.5 cm and (b) 1.0 × 1.0 cm, as measured by a dermatologist in 2012. The dermatologist’s diagnosis was pilomatrixoma. The patient did not accept surgical treatment. When the patient came to the acupuncture clinic in 2016, the nodule sizes were (a) 1.5 × 2.0 cm and (b) 1.3 × 1.5 cm, as measured by the acupuncturist. Both nodules had grown bigger in four years. There were no hairs growing on the skin of both scalp nodules. The nodules were subcutaneous, semi-hard, smooth edges, non-tender, and freely movable.

The nodules were treated by acupuncture 1-2 times a month since February 15, 2016. Three to six needles were inserted into each nodule during each treatment. The needle diameter was 0.22 mm at the beginning of the treatment plan, but increased to 0.35 mm in diameter after four months of treatment. The needle length inserted into the nodules ranged from 0.5 cm to 1.2 cm.  The large nodule (a) was treated 16 times and cured on September 26, 2016 and the small nodule (b) was treated 22 times and cured on February 6, 2017. The black hairs grew back in the scalp area as the nodules reduced in size.
