Cervical cancers are the third most common cancers of the female genital tract. Most of these neoplasms are human papillomavirus (HPV)-related squamous cell carcinomas and adenocarcinomas, but in addition a wide range of uncommon and rare tumors may occur. These may present particular diagnostic challenges resulting from their rarity and the differential diagnoses which may arise at this site. Neuroendocrine carcinomas (NEC) are not uncommonly encountered in routine practice. They are etiologically related to HPV and may be associated with squamous and adenocarcinoma or their precursors. Diagnosis of NEC is important as it has a poorer outcome and is treated aggressively with non-surgical modalities. Mixed tumors include the common cervical polyps and the rarer adenosarcomas. The latter has a potential for recurrence and sarcomatous overgrowth. Of the cervical sarcomas, embryonal rhabdomyosarcoma is the commonest at this site and has distinctive appearance and clinical profile. In general, accurate diagnosis of these entities is important in determining optimal patient management since some tumors may be associated with tumor syndromes and extracervical disease.

摘要

Cervical cancers are the third most common cancers of the female genital tract. Most of these neoplasms are human papillomavirus (HPV)-related squamous cell carcinomas and adenocarcinomas, but in addition a wide range of uncommon and rare tumors may occur. These may present particular diagnostic challenges resulting from their rarity and the differential diagnoses which may arise at this site. Neuroendocrine carcinomas (NEC) are not uncommonly encountered in routine practice. They are etiologically related to HPV and may be associated with squamous and adenocarcinoma or their precursors. Diagnosis of NEC is important as it has a poorer outcome and is treated aggressively with non-surgical modalities. Mixed tumors include the common cervical polyps and the rarer adenosarcomas. The latter has a potential for recurrence and sarcomatous overgrowth. Of the cervical sarcomas, embryonal rhabdomyosarcoma is the commonest at this site and has distinctive appearance and clinical profile. In general, accurate diagnosis of these entities is important in determining optimal patient management since some tumors may be associated with tumor syndromes and extracervical disease.
