Background. Vulva lactating adenoma is rare and may be misdiagnosed as adenocarcinoma in frozen section and aspiration cytology if breast tissue is not anticipated. Objective. To raise the awareness of lactating vulva ectopic breast lesion among clinicians and pathologists. Case Report. We present a case of vulva fibroadenoma associated with lactating adenoma in a 26-year-old Nigerian female. Conclusion. The rarity of vulva ectopic breast tissue can present a diagnostic challenge for both the clinician and the anatomical pathologist. Once excisional biopsy is done and the lesion confirmed histologically, the anxious patient can be reassured.
Background. Management of breast lumps can be challenging in resource poor settings. Fine-needle aspiration cytology (FNAC) especially when used with cell block can help improve affordability for the patients. Objective. To determine the diagnostic accuracy of FNAC of palpable breast lesions within a 5-year period. Methods. The findings obtained from FNAC of palpable breast lumps seen at the FNAC clinic of our department from January 2007 to December 2011 were retrieved and correlated with findings on histology of excisional biopsies. Results. A total of 1790 patients had FNAC of breast lumps during the 5-year period; 436 of them subsequently had biopsies. Our results compare favourably with the measures of test performance of the UK NHS Breast Screening Programme shown in brackets: absolute sensitivity 95.4% (>70%), complete sensitivity 99.2% (>90%), full specificity 88.9% (>65%), positive predictive value 99.6% (>99%), false-negative rate 0.8% (<4%), false-positive rate 0.4% (<0.5%), inadequate rate 3.2% (<15%), and suspicious rate 10.2% (<15%). Conclusion. Breast FNACs compare very well with histology of excisional biopsies and in experienced hands are extremely useful in the management of breast lumps. Further studies assessing the diagnostic accuracy of FNAC and cell blocks in our setting are recommended.
Background: Although fine needle aspiration cytology (FNAC) is highly accurate for detecting breast malignancies, concerns remain among cytopathologists about falsepositive and false-negative diagnoses. Cell block (CB) preparations have been advocated by some cytopathologists as one of the methods to improve and consolidate the diagnostic accuracy of FNAC. The aim of this study was to determine the diagnostic utility of CB in FNAC of palpable breast lesions among female patients. Methods: Following FNA, CBs were prepared using 10% neutral-buffered formalin from the residual breast aspirates of 100 consecutive female patients attending the FNAC clinic. The slides of the conventional smears, CB and excisional biopsies were examined, and results were analysed using the SPSS. Results: Of the 100 patients that had FNAC, 44 (44%) had excisional biopsy performed. An additional 13% diagnostic yield for malignancy was obtained with the use of CB preparations. CB reduced equivocal diagnoses by 25%, corresponding with 90.9% improvement on definitive diagnoses. Conclusion: In our setting, the addition of CB to smear remarkably improved the diagnostic utility of breast FNAC by minimising atypical and suspicious for malignancy diagnostic categories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
