Abstract

A case of the pigmented variant of the calcifying odontogenic cyst occurring in a 15-year-old West Indian girl is reported. Melanin pigment was widely distributed and appeared in greatest amount in cells exhibiting the appearance of stellate reticulum. Ultrastructural examination demonstrated large numbers of melanosomes in these cells but relatively few in epithelial ghost cells. The latter contained thick bundles of tonofilaments. Melanocytes were identified and two forms were distinguished, depending on their content of premelanosomes and fully melanized melanosomes.

摘要

报告了一例发生在一名15岁西印度女孩身上的钙化牙源性囊肿色素沉着变体病例。黑色素广泛分布，在呈现星网状外观的细胞中含量最高。超微结构检查显示这些细胞中有大量黑素小体，但在上皮幽灵细胞中相对较少。后者含有粗大的张力丝束。识别出了黑素细胞，并根据其前黑素小体和完全黑素化的黑素小体含量区分出两种形式。
