Pilomatricoma masquerading as metastatic squamous cell carcinoma
نویسندگان
چکیده
We present a case of a 58-year-old woman with a posterior neck mass who underwent fine-needle aspiration of the lesion, with initial cytopathologic evaluation being consistent with metastatic squamous cell carcinoma. However, following excisional biopsy of the tumor, histopathologic evaluation revealed a pilomatricoma. Appreciation of the difficulty in cytologic classification of this benign tumor and its propensity for confusion with more aggressive tumors may help prevent unintended and unnecessary invasive procedures as a result of erroneous diagnoses.
