Abstract
The structure of the cilia present in dermal melanocytes of 14 patient s with naevus of Ota was examined by electron microscopy. Cilia and ba sal bodies were found in 10 and 9 lesions, and in 39 and 18 dermal mel anocytes, respectively. In each case, 1-12 cells with a single cilium or multiple cilia were observed. In a total of 3 dermal melanocytes fr om 2 cases, two cilia per cell were observed. The cilia contained 7, 6 , 5 and 4 pairs of doublet microtubules in the periphery and no centra l microtubule. Another pattern with several pairs of doublet microtubu les in the periphery and one or two centrally located doublet microtub ules were also observed. The latter were not bona fide central microtu bules but one and two doublers, which seemed to be displaced to the ce ntre from the periphery of the cilium.
