It was first described by Hattori in 2005 and named as Hattori cyst. Histopathologically, diagnosis is based on the presence of ciliated epithelium with mullerian differentiation. Typically, the cyst epithelium is positive with ER, PR, PAX8 and WT-1, and the stroma constituting the cyst wall is positive with αα-smooth muscle actin (αα SMA).

Case: Herein, we presented a 42-year-old female patient with paravertebral cystic lesion who was diagnosed as Hattori Cyst due to the mullerian origin of epithelium which was positive with ER, PR and WT-1.

Conclusion: The case is presented because of being a rare entity that should be kept in mind in the differential diagnosis of other mediastinal cysts. Anahtar Kelimeler : Hattori, Mediastinal cyst, Mullerian differentiation
