case_images: We present a case of 65-year-old male presented to the general surgery outpatient department for the evaluation of a painless, superficial nodular mass in the left axilla that had slowly grown over a period of 2 years and measured 8 cm x 6 cm [Figure 1].

case_images: The smears were hypercellular, tumor cells forming cohesive clusters, isolated scattered singly, and at places forming a vague acinar pattern against the mucoid background [Figure 2].
