Background: Endometriosis is the presence of endometrial tissue outside the uterine cavity. The lesions are typically found in the pelvic cavity but can occur in other extrapelvic areas. Umbilical endometriosis, also known as Villar's node, is a rare disease comprising 0.5-1% of all extrapelvic disease. It commonly presents with cyclical pain and bleeding from an umbilical nodule. Case series: We present a retrospective case series of five African patients with umbilical endometriosis diagnosed and treated between July 2015 and February 2019 at a tertiary health facility. The patients were aged between 31 and 47 years, and all presented with an umbilical swelling and pain. They had lesions with diameters ranging from 1.6 cm to 4 cm. The duration of symptoms ranged between 3 and 60 months. Their diagnoses were made on the basis of clinical presentation followed by surgical excision. In all the cases, diagnosis was confirmed by histopathology with no malignancy detected. Conclusion: Umbilical endometriosis is a rare condition that should be considered as a differential diagnosis in women with umbilical lesions. Diagnosis is mostly clinical; most patients present with umbilical swelling, cyclical pain, and bleeding or discharge. Imaging has a limited role. Surgical excision is the treatment of choice with low risk of malignancy or recurrence.
Background The presence of the levonorgestrel-releasing intrauterine system embedded within an ectopic pregnancy is a rare occurrence. Tubal migration of an intrauterine device is not well understood and has not been extensively studied in literature. Case presentation A 34-year-old African woman, para 1, gravida 2, presented with symptoms of ruptured ectopic pregnancy. She underwent a laparoscopy where a ruptured left ectopic pregnancy was found with a levonorgestrel-releasing intrauterine system inserted 2 years prior embedded within the tube. A left salpingectomy was performed with removal of the levonorgestrel-releasing intrauterine system. The patient recovered well and proceeded to have an intrauterine pregnancy 3 months later. Conclusion Migration of the levonorgestrel-releasing intrauterine system into the fallopian tube is a rare occurrence that is not well understood. In the case presented, levonorgestrel-releasing intrauterine system was found embedded within the fimbrial end of the left fallopian tube, which had a ruptured ectopic pregnancy. Surgical treatment with laparoscopy is recommended for intraabdominal intrauterine device to prevent complications.
