A man needed seven stitches after being slashing in the face and neck at a Manhattan subway stop, cops said Thursday.

The 39-year-old was attacked inside the Fort Washington Avenue and West 181 Street subway station in Inwood on Nov. 21 just before 4 p.m. when an argument turned physical, cops said.

The unknown attacker slashed the man and ran off, according to police.

EMS rushed the 39-year-old to St. Barnabas Hospital, where he was stitched up and is in stable condition, police said.

It was unclear what sparked the dispute.

Police released an image of the suspect Thursday.
