In an ultrastructural study of 3 biopsies taken from the floor of the mouth of 2 patients suffering from sublingual keratosis, it was found that some of the mast cells appearing within the epithelium and connective tissue contained melanin granules which were found to be positive with Masson Fontana stain for melanin. These cells showed all the characteristic features of mast cells and not macrophages. The present results suggest that mast cells have phagocytosed melanin granules and therefore support those views suggesting that mast cells are capable of phagocytosis. They also suggest that not all the cells containing melanin granules and appearing in the lamina propria are the conventional melanophages but some of these may be mast cells.
在对2例患有舌下角化病患者口腔底部进行的3次活检的超微结构研究中，发现上皮和结缔组织内出现的一些肥大细胞含有黑色素颗粒，经Masson Fontana黑色素染色呈阳性。这些细胞表现出肥大细胞的所有特征，而非巨噬细胞。目前的结果表明肥大细胞吞噬了黑色素颗粒，因此支持了肥大细胞具有吞噬能力的观点。这些结果还表明，并非所有固有层中含有黑色素颗粒的细胞都是传统的噬黑素细胞，其中一些可能是肥大细胞。
