We report 3 cases of unusual cutis marmorata telangiectatica congenita (CMTC). The ages of the first two cases of CMTC were premature babies, born at intrauterine pregnancy of 31 weeks and 34 weeks. the other patient was a 45-year old female. Compared to the age of other cases reported in the literature our patients ages are unusual. It is not surprising that the first two cases of premature babies had typical signs because CMTC is a congenital disorder, usually seen at birth, but the fact that the skin lesion of CMTC appeared already in the early third trimester may provide some clues to the pathogenesis of CMTC. The third case seems to be very rare because most reported cases show that the skin lesion usually disappear gradually over a period of months to years. The site and size of the lesion in the last case was told to have been fixed for 45 years without any change.
