(a) Computed tomography of the head showing soft tissue lesion on scalp in the frontal region with destruction of underlying bone. (b) Cytological smear showing cells arranged in microfollicular structures and having monotonous enlarged hyperchromatic nuclei (Leishman, x100). (c) Immunocytochemistry showing positivity for Thyroglobulin (IHC, x200)

Smears showed cells arranged in a repeated microfollicular pattern having monotonous enlarged, hyperchromatic nuclei, reminiscent of follicular neoplasm of thyroid and were suspected to be metastasis from FTC [Figure 1b]. Immunocytochemistry was done and the cells showed positive staining for thyroglobulin [Figure 1c] and cytokeratin. Contrast enhanced computed tomography (CT) demonstrated a 3 x 3 cm soft tissue lesion in scalp in frontal region with destruction of underlying bone [Figure 1a].
