Introduction.
Pinworms are one of the factors which can cause the signs of acute appendicitis. However, they occupy appendix vermiformis only in the 1,3% of the all cases of oxyuriasis.

Aim.
The aim of our study was estimation of the frequency of pinworms’ occurrence in the appendix' lumen within the last five decades and evaluation of it's role in the frequency of performed appendectomy due to acute appendicitis.

Material and methods.
The study was conducted retrospectively on 504 pathologic diagnosis of the resected appendices due to acute appendicitis performed in the years 1965-68, 1972-75, 1985-88, 1995-98, 2004-07 (female: 277 , male: 207 , average age: 34,8 years) in the Surgery Department of Międzyleski Specialist Hospital in Warsaw.
The frequency of the pinworms' occurrence in the appendix' lumen, the character of inflammation, the predispositions of sex and age was estimated. The frequency was compared with the estimated frequency of acute appendicitis in Mazowsze Province based on statistics for particular decades provided by Państwowy Zakład Higieny and Central Office of Statistics.

Results.
The pinworms' occurrence in the appendix' lumen was observed three times more seldom in male than in female (1,5% vs. 4,7%); youngsters predominantly (average age 19,1 years). The inflammation of the appendix settled by pinworms was most often chronic (75%), rarely chronic exacerbated (19%) and occasionally it was acute phlegmonous appendicitis (6%). The frequency of the pinworms' occurance in the appendix within successive decades was following:
• 9% in the '60s.
• 5% in the '70s.
• 1% in the '80s.
• 1% in the '90s.
• 0% in the years 2004-07
The frequency of acute appendicitis in Mazowsze Province, based on statistics provided by Państwowy Zakład Higieny and Central Office of Statistics, was 0,088% in the ‘70s and 0,083% in 2005.

Conclusions.
• Pinworms were noticed most often in patient operated in the 60’s and the ‘70s.
• It is highly probable that pinworms that settled the appendix caused the signs of acute appendicitis.
• Oxyuriasis is nowadays uncommon disease, though 40 years ago every ten percent of appendectomies could be performed due to this parasitosis.
• Despite the decrease of pinworms' prevalence in appendix, current frequency of performed appendectomies is similar to that in the 70's.
