ABSTRACT
Unilateral simian crease (USC) is a single transverse crease that extends from across the palm of one of the hands. The presence of a single transverse palmar crease or the simian crease (SC) can be seen in normal individuals. The significance of USC lies in the fact that it can also be associated with abnormal medical conditions. Literature review indicates that there is strong coincidence with the presence of a SC and presence of genetic or chromosomal abnormalities in these subset of patients. USC is seen in 10% of the population. In this case report, a three year old child was detected to have a SC, especially an USC in one of his palms.
ABSTRACT
Keratosis punctata of the palmar creases (KPPC) is rare skin condition characterized by punctiform hyperkeratotic pits confined to the palmar and digital creases. Although this condition has been regarded as a variant of classical punctate keratoses, there are some differences between classical punctate keratosis and KPPC. We herein report a case of KPPC in a 22-year-old man who had numerous, tiny, hyperkeratotic pits limited to the palmar creases of both hands with typical histologic findings.
