metriosis were found (0.15% in the enꢀre cohort and
0
.36% in the female populaꢀon of 543 paꢀents). In this
series, as 88 paꢀents did not present appendiciꢀs, the
incidence of appendiceal endometriosis among these
1
paꢀents was 2.27% .
In 2017, Dincel et al. reviewed 1970 appendec-
tomy specimens with diagnosis of acute appendiciꢀs
and found 59 cases of rare histopathological findings
(
other than appendiciꢀs). They found only one appen-
diceal endometriosis (0.05% of all the specimens and
2

.69% in the specimens with unusual findings) .
In 2014, Hakan Guven et al. reported the
analysis of 48 paꢀents undergoing right hemicolectomy
due to cecal masses mimicking acute appendiciꢀs and
found two cases of appendiceal endometriosis (4.16%).
These two paꢀents were part of 16 paꢀents in whom

malignancy was suspected .
The preoperaꢀve diagnosis of appendiceal en-
dometriosis is difficult, parꢀcularly in those paꢀents
with unclear clinical presentaꢀon. Several protocols
have been described to evaluate paꢀents with pelvic
endometriosis, as magneꢀc resonance imaging to de-

tect foci of extrapelvic bowel endometriosis . However,
the preoperaꢀve diagnosis is difficult and in most cases
the final diagnosis is made by pathological examinaꢀon
