Preoperative cytological diagnosis of malignant mesothelioma of tunica vaginalis

Diagn Cytopathol. 2015 Oct;43(10):850-4. doi: 10.1002/dc.23325. Epub 2015 Jul 30.


Malignant mesothelioma of tunica vaginalis testis is a rare aggressive neoplasm with ∼200 cases reported so far. A correct preoperative diagnosis of this rare tumor is difficult. Fine-needle aspiration cytology (FNAC) is a rapid and inexpensive diagnostic tool that may prove helpful in such cases. Very few cases have been diagnosed on cytology so far, and the descriptions of the cytological features have rarely been described in the literature. In this report we present the cytological features of malignant mesothelioma of tunica vaginalis testis which was diagnosed by FNAC and subsequently confirmed by histopatholoy and immunohistochemical (IHC) studies.

Keywords: FNAC; Tunica vaginalis; malignant mesothelioma.
