A case of ovarian clear cell adenofibroma of borderline malignancy in a 59-year-old woman is presented with histochemical and electron microscopic observation. The tumor was histologically composed of tubular component lined in part with flat or cuboidal clear as well as hobnail cells with mild cytologic atypia and abundant stromal component containing foci of calcification. The epithelial cells had diastase-digestive PAS-positive material in the cytoplasm, and occasionally the luminal surface and intraluminal substance were stained with mucicarmine. Some of the epithelial cells showed positive lipid staining with Sudan III stain. On ultrastructural study, the tumor featured a moderate number of small mitochondria, poorly developed rough endoplasmic reticulum (rER), short microvilli, intercellular tight junction and desmosome and small amount of glycogen granules. The patient is alive and well with no evidence of recurrence six and half years after the operation.
