An unusual cause of abdominal pain in a male patient: endometriosis
Open accessAbstract
A rare case of abdominal pain secondary to endometriosis in a 52-year-old man with cirrhosis is presented. The patient had a repair of recurrent inguinal hernia 7 months prior to presentation. An exploratory laparotomy revealed a 4.5 cm × 2.5 cm cystic mass attached to the urinary bladder and the inguinal area. The mass pathology showed a cystic lumen of diameter of 1.5 cm filled with old blood and surrounded by thick muscular mass. Microscopically, the lesion consisted of thick smooth muscle fibers that concentrically surround a central lumen that is bordered by endometrium such as glands and stroma. Immunostains were positive for estrogen receptors and progesterone receptors in the glandular component and for CD10 in the stroma, which is consistent with endometriosis.

The retrograde menstruation and implantation theory does not explain all clinical observations, such as extragenital endometriosis, endometriosis in women without endometrium and in men, or the clonal aspect.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
