[Large mucocele of the appendix imitating an ovarian cyst].

Mukokela appendix--described by Rokitansky in 1842 for the first time--appears in 0,2% of appendectomy at Bulovka-Hospital Prague. Great mukokela appendix (12,5 x 5,5 cm), which resembled ovarial cyst on the right hand side, had been found for the first time in 20 years. The patient was a 63 old woman; she was cured in 9 days after appendectomy. The authors describe etiology, clinic and the case itself.
