title: Cytodiagnosis of pilomatrixoma from an uncommon site with unusual presentation.
abstract: Pilomatrixoma or pilomatricoma is an uncommon benign tumor of hair matrix origin, which most commonly occurs in the head and neck region and upper extremities. In this study, we report a case of pilomatrixoma of a 35-year-old female presenting with left-leg swelling with surface ulceration, clinically thought to be malignant. Fine-needle aspiration cytology (FNAC) of the lesion showed clusters of basaloid cells with round to ovoid nuclei, nucleated squamous cells, and anucleated squames and clusters of shadow cells. Acytological diagnosis of pilomatrixoma was made. Subsequent surgical excision and histopathological examination confirmed the diagnosis. This case highlights a rare site of presentation and the role of FNAC in preoperative diagnosis of this benign tumor for proper management.
