A clinicopathological analysis of cervical carcinoma with basaloid features / 实用医学杂志

ABSTRACT

Objective To investigate the clinical and pathological features of adenoid basal cell carcinoma(ABC),adenoid cystic carcinoma(ACC),and basaloid squamous cell carcinoma(BSCC)with basaloid charac-teristics and improve the diagnostic and differential diagnostic ability of clinicians and pathologists for these lesions.Methods A retrospective study was conducted on the clinical and pathological data of 4 cases of ABC,1 case of ACC,and 3 cases of BSCC diagnosed and treated at Shenzhen Maternal and Child Health Hospital,Southern Medical University from April 2018 to December 2022.Pathological slides were reviewed and relevant literature was analyzed and summarized.Results All three types of tumors were common in postmenopausal women and were associated with high-risk HPV infection.ABC was a low-grade cancer and patients were often clinically asymp-tomatic.It was usually detected incidentally during cervical screening due to cytological abnormalities,or after cervical cone biopsy or hysterectomy for HSIL.It presented as superficial cervical infiltration and clinical staging was often early.ACC and BSCC were intermediate to high-grade cancers and they often presented with postmenopausal vaginal bleeding.A visible mass was observed on the cervix.The clinical staging was intermediate to advanced.The three types of lesions could coexist.Careful observation of the morphological characteristics and immunohistochemical staining could help with differential diagnosis.None of the 8 patients experienced recurrence or metastasis during follow-up.Conclusion Cervical ABC,ACC and BSCC are rare and they originate from reserve cells.They share the similarities in clinical and pathological morphology,but differ in treatment and prognosis.So,accurate differen-tiation among them has important clinical significance.
