Synchronous invasive squamous cell carcinoma and clear cell adenocarcinoma of the uterine cervix: a different human papillomavirus status.

BACKGROUND

A multiple primary invasive carcinoma of the cervix is a rare condition and is seldom composed of squamous cell carcinoma and clear cell adenocarcinoma.

CASE: A 47-year-old woman presented with contact bleeding. The anterior lip of the cervix revealed a 2.0-cm protruded mass. Preoperative pathological and imaging studies demonstrated the squamous cell carcinoma of the exocervix alone. Radical hysterectomy was performed on the diagnosis of stage 1B cervical cancer. Histological examination of the specimen manifested a coexisting invasive clear cell adenocarcinoma in the endocervix. Human papillomavirus (HPV) 18 was detected in the squamous cell carcinoma; however, no HPV was detected in the clear cell adenocarcinoma.

CONCLUSION

This finding suggests that there was an obvious difference in association of HPV with the two neoplasms.
