This retrospective study analyzed six cases of primary umbilical endometriosis treated between 2000 and 2013, focusing on clinical presentation and diagnostic accuracy. The patients, with a mean age of 39.1 years, presented with cyclically painful umbilical nodules, though two were initially misdiagnosed as umbilical hernias prior to surgical excision. While the abdominal lesions were successfully removed, subsequent gynecological evaluation revealed bilateral ovarian endometriosis in one-third of the cohort despite no prior history of pelvic disease. This paper is centrally about endometriosis — specifically the rare primary umbilical variant and its association with concurrent ovarian involvement.

Abstract

La endometriosis es la presencia de tejido endometrial extrauterino. Su localización habitual es intrapélvica, pero también puede aparecer en otras localizaciones. La endometriosis de pared abdominal es rara, y puede ser primaria o, más frecuentemente, secundaria a la cirugía (sobre todo ginecológica u obstétrica). La forma primaria más frecuente es la umbilical, con una incidencia estimada del 0.5-1 % en las pacientes con ectopia endometrial. Realizamos un estudio observacional, descriptivo y retrospectivo de 6 pacientes intervenidas por endometriosis umbilical primaria entre 2000 y 2013 en nuestro servicio. En todas las pacientes se recogieron variables clínicas (edad, antecedentes de cirugía o endometriosis conocida, clínica, método diagnóstico, tratamiento) y de seguimiento. La edad media fue de 39.1 años. Ninguna de las pacientes presentaba historia previa de endometriosis pélvica. El tamaño medio de las lesiones fue de 2.75 cm. La presentación clínica fue un nódulo umbilical doloroso de forma cíclica en todas las pacientes, asociado a sangrado en la mitad de los casos. El diagnóstico preoperatorio correcto se realizó en 4 pacientes, en tanto que las otras 2 se intervinieron con diagnóstico de hernia umbilical. El tratamiento consistió en la exéresis de la lesión. Todas las pacientes fueron remitidas posteriormente a ginecología, donde se demostró la presencia de endometriosis ovárica bilateral en 2 casos. La endometriosis umbilical es una patología poco frecuente en el campo de la cirugía general. Debe incluirse en el diagnóstico diferencial en mujeres con patología umbilical. El tratamiento de elección es la exéresis con márgenes adecuados. Endometriosis is the presence of extrauterine endometrial tissue. The usual location for endometriosis is intrapelvic, but it may also appear in other areas. Abdominal wall localization is quite rare and, although it may appear in a primary form, its more usual presentation is usually secondary to gynaecological or obstetric intervention and, in such cases, over abdominal scars. The umbilicus is the most common site for primary endometriosis and represents 0.5-1 % of all cases of ectopic endometrial tissue. The present observational, descriptive and retrospective study was performed between 2000 and 2013 in 6 cases of primary umbilical endometriosis diagnosed in our service. Age, surgical or endometriosis history, symptomatology, preoperative diagnosis, treatment and evolution were analyzed. Mean age of the patients was 39.1 years. None of the patients had a history of pelvic endometriosis. Lesions averaged 2.75 cm in diameter. The clinical presentation was an umbilical nodule with cyclical pain (100 %) and bleeding (50 %). The correct preoperative diagnosis was made in four patients. In the remaining patients 2 umbilical hernias were diagnosed. Treatment was wide surgical excision. All patients were subsequently referred to the gynecology service for follow-up, where ovarian bilateral endometriosis was found in 2 patients. Endometriosis is an uncommon condition in the field of general surgery. It should be included in the differential diagnosis of women presenting with an umbilical swelling. Treatment consists of surgical excision.

Abstract

Introduction: Endometriosis is the presence of extrauterine endometrial tissue. The usual location for endometriosis is intrapelvic, but it may also appear in other areas. Abdominal wall localization is quite rare and, although it may appear in a primary form, its more usual presentation is usually secondary to gynaecological or obstetric intervention and, in such cases, over abdominal scars. The umbilicus is the most common site for primary endometriosis and represents 0.5-1 % of all cases of ectopic endometrial tissue.

Material and methods

The present observational, descriptive and retrospective study was performed between 2000 and 2013 in 6 cases of primary umbilical endometriosis diagnosed in our service. Age, surgical or endometriosis history, symptomatology, preoperative diagnosis, treatment and evolution were analyzed.

Results

Mean age of the patients was 39.1 years. None of the patients had a history of pelvic endometriosis. Lesions averaged 2.75 cm in diameter. The clinical presentation was an umbilical nodule with cyclical pain (100 %) and bleeding (50 %). The correct preoperative diagnosis was made in four patients. In the remaining patients 2 umbilical hernias were diagnosed. Treatment was wide surgical excision. All patients were subsequently referred to the gynecology service for follow-up, where ovarian bilateral endometriosis was found in 2 patients.

Conclusion

Endometriosis is an uncommon condition in the field of general surgery. It should be included in the differential diagnosis of women presenting with an umbilical swelling. Treatment consists of surgical excision
