Endometriosis is defined as the presence of endometrial tissue outside of the uterine cavity, commonly occurring in women of reproductive age. The condition usually affects the adnexa (ovaries, Fallopian tubes, and associated ligaments and connective tissue) but can also be seen in extrapelvic structures.
Cutaneous endometriosis is an uncommon subtype that accounts for 1% of endometriosis cases and occurs when endometrial tissue is found on the surface of the skin. It is divided into primary and secondary cutaneous endometriosis. The that may lead to seeding of endometrial tissue on the skin. In the case of our patient, it appears that her laparoscopic procedure 2 years ago was the cause of endometrial seeding in the umbilicus.
Clinically, the condition may present with a palpable mass, cyclic pain, and bloody discharge from the affected area. Due to the rarity of cutaneous endometriosis, it may be hard to distinguish from other diagnoses such as keloids, dermatofibromas, hernias, or cutaneous metastasis of cancers (Sister Mary Joseph nodules).
The definitive diagnosis can be made by biopsy and histopathological assessment showing a mixture of endometrial glands and stromal tissue. Imaging studies such as computed tomography (CT) scan and magnetic resonance imaging (MRI) are helpful in excluding more common diagnoses such as hernia or cutaneous metastasis. In this patient, the mass was surgically excised. Histopathological assessment established the diagnosis of cutaneous endometriosis.
Treatment options include surgical excision and medical therapy. Medical therapy entails the use of hormonal agents such as gonadotropin-releasing hormone agonists, danazol (a pituitary gonadotropin inhibitor), and oral contraceptives, which reduce the cyclical proliferation of endothelial tissue. These agents can be used preoperatively to reduce the size of the cutaneous mass before surgical excision, or as an alternative treatment for patients who wish to avoid surgery. The rate of recurrence is observed to be higher with medical therapy rather than surgical treatment.
