This paper reports three cases of intestinal endometriosis presenting with tumor-like lesions or severe bowel stenosis, investigated through intraoperative frozen section and histopathology, with attention to coexisting female genital tract involvement. In the 41-year-old patient, a sigmoidal tumorlike lesion with pericolic lymph node involvement and suspected malignancy was shown histologically to be intestinal endometriosis involving pericolic lymph nodes, uterus, left tube, and right ovary under an adenomyosis pattern; the two other 26-year-old patients had sigmoid disease causing marked fibrosis with stenosis up to 75% and one had blood in stool. The authors emphasize a key limitation: enteric endometriosis remains difficult to diagnose and cannot be reliably excluded clinically when lymph nodes are involved. This paper is centrally about endometriosis — it details tumor-like intestinal endometriosis with lymph node involvement and discusses diagnostic differentiation from malignancy.

Schwierigkeiten ergeben sich bei der Differenzialdiagnose zu malignen Darmtumoren. Eine 41-jährige Patientin zeigte einen Gewichtsverlust von 13 kg in 4 Monaten und einen 7 × 5 × 4 cm polyzystischen Tumor im rechten Unterbauch, bildmorphologisch malignitätsverdächtig. Im intraoperativen Schnellschnitt und histologisch ergab sich eine Endometriose des resezierten Sigmas, perikolischer Lymphknoten, des Uterus, der linken Tube und des rechten Ovars unter dem Bild einer Adenomyose. Eine 26-jährige Patientin mit Douglasendometriose wies eine Mitbeteiligung des Sigmas 20 cm ab ano mit hochgradiger Stenose des Darmes auf. Eine 26-jährige Patientin zeigte eine multifokale Sigmaendometriose mit Blutabgang im Stuhl und hochgradiger Darmstenose. Die intestinale E. sollte bei Frauen in der Prämenopause in die Differenzialdiagnose von Darmtumoren mit einbezogen werden und bedarf, insbesondere bei einer Lymphknotenbeteiligung, der Abgrenzung zu malignen Tumoren. Summary Intestinal endometriosis (e.) is a rare lesion and commonly affects those parts of the bowel that lie in proximity to genital organs. Most patients are asymptomatical and the need for intestinal resection is even less uncommon. We present three cases with clear-cut symptoms, one with tumor-like lesion and the inability to exclude malignancy clinically. One 41-year-old woman presented with a tumorlike sigmoidal e. with involvement of pericolic lymph nodes and a 26-year old patient with a stenosis of the large bowel, caused by strong chronic inflammation and fibrosis of the sigmoidal endometriosis. A second 26-year-old woman had intestinal e. of the sigmoid, accompanied with marked fibrosis of the wall of the bowel, performing stenosis up to 75 %. Additionally, all patients had developed endometriosis of the female genitalia. In conclusion, enteric endometriosis continues to be difficult to diagnose and must be considered in young women with cyclic history of abdominal pain and associated tumorous intestinal lesions.
