This article describes the light and electron microscopic studies from a macule and the surrounding lightly hyperpigmented skin of a patient with the Cronkhite‐Canada syndrome. Increased numbers of melanin granules in keratinocytes, increased numbers of melanosomes in melanocytes, and areas with increased numbers of melanocytes were found in the macular lesion. Skin from both the macule and surrounding area were also characterized by compact hyperkeratosis as well as perivascular inflammation and exocytosis not previously reported in these patients.
