Introduction:
Endosalpingiosis is a rare condition and its pathogenesis and clinical significance are not fully understood. The unfamiliar presentation of this disease can misguide health care professionals. The reports available on this matter describe it as a disease of older age. In the majority of the cases it is an incidental finding in those with other concurrent gynecologic conditions.
Presentation of case:
Here we report the case of a 14-year-old female who presented with abdominal pain and no specific past medical history. Imaging and physical examination were highly suggestive of appendicitis. With the initial diagnosis of acute abdomen, she underwent surgery. During the surgery gastrointestinal tract organs were found to be normal and in gynecological examination, the ovaries were normal, however the fallopian tube revealed a twisted paratubal cyst which was removed and sent to the laboratory for further investigation. On the basis of the cellular pathology, tubal like epithelium in the cyst was found and patient diagnosed with endosalpingiosis.
Discussion:
We suggest that in our case, the lesion possibly originated from the metaplasia of coelomic membrane into tubal cells. There are studies suggesting that co-occuring diseases should be considered when the diagnosis of endosalpingiosis is established and further studies are needed in regard to this matter.
Conclusion:
Endosalpingiosis, although being a rare condition, should be included in our differential diagnosis since co-existing comorbidities are a possibility in patients with endosalpingiosis and can be of great importance.
