Abstract
BACKGROUND
Anaplastic carcinoma mural nodules in ovarian mucinous tumors are very rare. This study aimed to report the morphological characteristics, molecular detection results, clinical treatment and prognosis of three ovarian mucinous tumors with mural nodules of anaplastic carcinoma.
CASE SUMMARY
The pathomorphological features, molecular detection results, clinical treatment and prognosis of anaplastic carcinoma mural nodules were described in three cases. In case 1, sarcoma-like mural nodules (SLMNs) coexisted with anaplastic carcinoma mural nodules. No mutation was found in mucinous tumors. KRAS mutation was found in anaplastic carcinoma nodules and heterotypic cells were found in SLMNs. In case 2, KRAS mutation occurred in the mucinous epithelium and BRAF mutation occurred in mural nodules. In case 3, both mural nodules and mucinous tumors had the same KRAS mutation and a morphological transition between them was observed. All three patients died within 2 years, whether receiving chemotherapy or not.
CONCLUSION
Anaplastic carcinoma mural nodules may develop from dedifferentiation of mucinous tumors or are unrelated to mucinous tumors.
Core Tip: Anaplastic carcinoma mural nodules in ovarian mucinous tumors are rare. The pathomorphological features, molecular detection results, clinical treatment and prognosis of anaplastic carcinoma mural nodules were described in three cases. After limited molecular detection, it is inferred that the mural nodules of anaplastic carcinoma may arise from (1) dedifferentiation of mucinous tumors or (2) a tumor unrelated to mucinous tumors and the KRAS signal pathway may be involved in the formation of this tumor and is unrelated to mucinous tumors. The KRAS signal pathway may be involved in the formation of mural nodules of anaplastic carcinoma. The mural nodules of anaplastic carcinoma may promote the progression of borderline mucinous ovarian tumors.
