Popis: Hair distribution on the dorsum of phalanges of the hand was studied on 302 Chinese subjects (134 males and 168 females) randomly selected from the residents of Kota Bharu, Malaysia. Proximal phalangeal hair was seen on the dorsum of both hands in 99.3% of male subjects but in only 85.1% of female subjects. Chinese females showed a significantly lower (p < 0.05) incidence of proximal phalangeal hair on the hands than Chinese males. Comparison with other racial groups showed that Chinese females had significantly less (p < 0.05) hair on the proximal phalanges of the hands than Malay and African (Nigerian) females. The least common digital combination of proximal phalangeal hair in female subjects was the presence of proximal phalangeal hair only on the fourth digit (ring finger) and was noted in 0.6% of subjects. This has not been reported before. The frequency of middle phalangeal hair (MPH) distribution in Chinese falls between that in Malays and in Japanese which is probably explained by the fact that all these three racial groups originate from Asia. A study of digital combination of MPH in Chinese showed that the most common and the least common combinations in the Chinese differ considerably from those in other races. A total of 16 patterns of hair distribution was noted on the dorsum of the phalanges of the hands in Chinese subjects. Our study showed that though Chinese females had less digital hair on the hands than Chinese males, they showed a much larger variety of patterns of digital hair distribution than males.
