Papillary squamous cell carcinoma of the uterine cervix: diagnostic pitfalls.
A case of papillary squamous cell carcinoma (PSCC) of the uterine cervix is reported. The patient was a 73-year-old Japanese woman with acute renal failure and bilateral hydronephrosis. A cauliflower-like mass was found in the uterine cervix. A uterine cervical biopsy specimen revealed PSCC in situ, while clinically it was an invasive carcinoma. Uterine cervical biopsy was performed a second time to confirm its stromal invasion. However, only small fragments were obtained because of heavy bleeding from the tumor and they showed PSCC in situ again. Following this, computed tomography of the pelvis revealed a 5 cm mass in the uterine cervix, invading the vagina and urinary bladder. Though deep-wedge biopsy, loop electrosurgical excision, or cone biopsy is recommended to evaluate PSCC, it may be impossible to perform any of these procedures because of bleeding such as that seen in our case. In these circumstances, good communication between pathologists and clinicians is important since lack of communication may cause PSCC to be microscopically misinterpreted as in situ carcinoma rather than invasive carcinoma.
