Supergiant infrared stars with OH maser emissions, like NML Cyg, VY CMa, and VX Sgr, are discussed assuming a model consisting of a star with a photospheric temperature of about 2000 K and a radius of R ∼ 2 × 1014 cm surrounded by a gas and dust shell. A possible similarity with OH Miras is mentioned.
