To clarify the nature of the intracytoplasmic globules seen in the endothelial cells of the cutaneous angiomas of the Crow‐Fukase syndrome, we performed light and electron microscopic as well as immunohistochemical studies. The proliferating plump endothelial cells of the angioma located in the mid‐dermal portion contained numerous globules. IgG, A, M, and kappa and lambda light chain globulins were present in the endothelial cells containing these globules. Electron microscopy revealed osmiophilic fine fibrillar structures and amorphous substance in the globules. Thiéry staining for detection of vicinal‐glycol radicals of carbohydrate demonstrated the deposition of fine silver particles as a reaction product. We consider that the intracytoplasmic globules are phagolysosomes containing glycoprotein.
