Peritoneal keratin globules in uterine adenosquamous carcinoma

We have described a previously unreported lesion--peritoneal keratin globules in uterine adenosquamous carcinoma. We postulate that the keratin globules are derived from sloughed uterine adenosquamous carcinoma which gains access to the peritoneum through retrograde dissemination via the fallopian tubes, and we suggest that the finding of these globules does not alter the prognosis and staging of the primary carcinoma.
