Background: In Mexico, cervical carcinoma is the second leading cause of cancer death in women, which can be prevented if it is detected promptly with cervicovaginal cytology, however, this can be unsatisfactory even with neoplasia, so it is important to follow up to avoid underdiagnosing and delay treatment. In this hospital, this has not been previously studied. Objective: The objective of the study was to know the prevalence of lesions identified by cytology, colposcopy, biopsy, or hysterectomy, within 3 years after an unsatisfactory cytology. Materials and methods: Was reviewed the information about 156 cases of unsatisfactory cytologies during 2013 and 2014 that were followed up within next 3 years, at the General Hospital of Mexico "Dr. Eduardo Liceaga". Results: A total of 156 cases with follow-up were categorized the 1 st year in 119 (76.3%) negative, 27 (17.4%) positive, 1 (0.6%) atypical squamous cells cannot exclude a high-grade lesion, and 9 (5.8%) inadequate; the 2 nd year: 31 (79.5%) negative, 6 (15.5%) positive, and 2 (5.1%) unsatisfactory; the 3 rd year: 12 (92.3%) negative and 1 (7.7%) carcinoma. According to the method by which the definitive diagnosis was made at follow-up, negative results were obtained by cytology 85 (54.5%), colposcopy with cytology 6 (3.8%), colposcopy with biopsy 20 (12.8%), and hysterectomy 8 (5.1%); positive results were obtained by cytology 7 (4.4%), colposcopy with cytology 8 (5.0%), electrosurgical loop 4 (2.4%), colposcopy with biopsy 8 (5.0%), and hysterectomy 1 (0.6%). Conclusions: Unsatisfactory cervicovaginal cytology is associated with the presence of preneoplastic and neoplastic lesions during their follow-up 3 years after this result.

Background: Several diseases can produce enlargement of salivary glands and the fine-needle aspiration biopsy (FNAB) helps establishing a diagnosis. Methods: A retrospective study was conducted, in which the interpretation of 383 of salivary gland FNAB studies was evaluated, with the histopathological findings of the follow-up biopsies performed from 2009 to 2016, at Hospital General de México "Dr. Eduardo Liceaga. " The presence or absence of malignant neoplasm in the surgical specimens (gold standard) was considered as a positivity parameter. Results: To detect malignancy, a sensitivity ratio of 62.5%, specificity of 98%, positive predictive value of 90.9%, and negative predictive value of 90.1% were obtained with diagnostic accuracy of 90.2% of the salivary gland FNAB. Adenoid cystic carcinoma was the most frequent cytological interpretation of a specific malignant neoplasm and pleomorphic adenoma of a benign neoplasm. Conclusions: Salivary gland FNAB provides accurate and useful information about the type of pathology, which allows for better management of patients. Our results are similar to the parameters established in literature.
