Abstract Chordoma is an uncommon tumor initially believed to be benign due to the rarity of its metastasis. Cytological, morphological, and immunohistochemical features of chordoma, relating to its origin from notochordal remnants, allows for its accurate diagnosis. A 75‐year‐old man with a known history of tuberculosis (TB) presented with shortness of breath and a dry cough. A chest X‐ray demonstrated a diffuse, infiltrative miliary pattern in both lungs. Bronchial washings submitted for culture and cytological examination did not identify any tuberculous bacilli. Fine needle aspiration cytology (FNAC) showed focal areas of myxoid regions with small, round, uniform mononuclear cells. There was a documented past history of chordoma arising from the L2 vertebrae. Because of the rarity of this lesion in the lung and the limited diagnostic material available with a clinical history of TB and lumbar chordoma, the pathological report rendered on the FNAC was “atypical cells suspicious for metastatic chordoma.” A wedge biopsy of the lung confirmed the presence of metastatic pulmonary chordoma. Despite palliative treatment, he died within a year. Although the metastatic potential of chordomas has been recognized and documented, to the best of our knowledge, metastasis of chordoma to the lung diagnosed by FNAC with cytohistological correlation has not been previously reported in the English literature.
