title: Oncocytic adenocarcinoma of the ovary.
abstract: A rare case of ovarian adenocarcinoma with extensive oncocytic differentiation is presented. Light and electron microscopy examination and a specific stain for mitochondria (chromotrope-alcian blue) confirmed the diagnosis. The tumour cells revealed abundant granular and eosinophilic cytoplasm containing a large number of mitochondria. The tumour had a malignant infiltrative pattern and cellular atypia.
