Abstract:
We report two familial cases of reticulate acropigmentation of kitamura in 20-year-old male and 29-year-old female patients in which reticualte, brownish, slightly depressed pigmentation developed on acral parts of extremities and subsequently extended proximally. Characteristic pits and breaks on palms and soles were noted. Histologic findings revealed epidermal atrophy and enlongation of rete ridges with large amounts of melanin. Electron microscopic findings showed increased melanogenesis in melanocytes and numerous melanosomes and melanosome complex in keratinocytes.
