Fig. 1From: Comparison of clinical behavior between mucinous ovarian carcinoma with infiltrative and expansile invasion and high-grade serous ovarian carcinoma: a retrospective analysisRepresentative images of mucinous carcinoma (MC) with infiltrative invasion and MC with expansile invasion. AÂ MC with infiltrative invasion was characterized by obvious evidence of destructive stromal invasion. (x40) (B) Stromal invasion consisted of malignant glands, cell nests, and a desmoplastic stromal reaction (x200). CÂ MC with expansile invasion was marked glandular crowding, creating a labyrinthine appearance with little intervening normal ovarian stroma (x40). DÂ Back to back malignant glands were seen in MC with expansile invasion (x200). EÂ HGSC was characterized by solid, papillary, labyrinthine with slit-like spaces, glandular, or cribriform architecture (x40). FÂ Large and markedly atypical nuclei, with high mitotic activity including atypical mitoses, were seen (x200)Back to article page
