• We present a case of multiple mucinous metaplasia and neoplasia of cervix, endometrium, fallopian tube, ovary, and mesenterium with external urethral meatus neoplasm.
• Immunohistochemistry showed almost same pattern in each neoplasms.
• PCR-direct sequencing showed no existence of both KRAS and GNAS mutations.
