FNAC (fine needle aspiration cytology) was performed as part of the triple test, and air-dried, May-Grunwald-Giemsa-stained smears interpreted by the cytopathologist on duty revealed dissociated mononuclear cells of uncertain origin (Figure 2).
Mononuclear cells positive for Melan-A, consistent with metastatic cells.
