Bullous Pilomatrixoma: Without a Shadow of Doubt – Role of ROSE and Cytology

The article discusses a case of bullous pilomatrixoma, a rare benign skin tumor, in a 20-year-old female. The tumor, located on the right suprascapular region, was diagnosed using fine needle aspiration cytopathology (FNAC) and rapid on-site evaluation (ROSE). The cytological analysis revealed basaloid cells, ghost cells, and calcification, confirming the diagnosis. The study highlights the diagnostic challenges of pilomatrixoma and the utility of FNAC with ROSE in providing a definitive diagnosis. The patient underwent successful surgical excision, and the histopathology confirmed the initial diagnosis. The article emphasizes the importance of accurate sampling and cytological evaluation in diagnosing pilomatrixoma.
