Gross appearance and histology of the resected section. (a) The cut surface showing a large cystic lesion with a thickened wall and a hematoma. Boxed areas correspond to the areas shown in b and c. (b) On histology, the large cystic lesion was occupied by a hematoma and not lined with epithelial cells (hematoxylin and eosin stain). (c) Small multilocular lesions around the large cystic lesion were lined with epithelial cells (hematoxylin and eosin stain). (d) Magnified view of the image in c. These epithelial cells contained abundant eosinophilic cytoplasm and round nuclei, presenting as papillary growths without ovarian-like stroma (hematoxylin and eosin stain).
