Renal Endometriosis Mimicking Cystic Renal Tumor: Case Report and Literature Review

Background: Endometriosis mainly affects female pelvic tissues and organs, and the presence of endometriosis in the kidney is extremely rare.

Case Presentation: We report a case of a 48-year-old woman who presented with intermittent hematuria. She was found to have a cystic mass on renal ultrasonography, and contrast-enhanced computed tomography (CT) showed slight enhancement of the cystic wall and septa. These findings were indicative of cystic renal tumor. The patient subsequently underwent partial right nephrectomy. Histopathology revealed endometriosis of the right renal parenchyma. The patient recovered well and had no evidence of a recurrent renal mass at the 3 months' follow up.

Conclusion: The possibility of renal endometriosis should be considered in a female patient with a cystic renal mass and clinical symptoms related to the menstrual cycle.

New findings in non-invasive imaging of cutaneous endometriosis: Dermoscopy, high-frequency ultrasound and reflectance confocal microscopy

BACKGROUND

Cutaneous endometriosis (CE) is rare and its dermoscopic features were reported only in 3 patients. The aim of this study was to examine a case of pigmented CE with multiple non-invasive imaging techniques, to compare the obtained images with histopathology and to define their utility in an early diagnosis of the disease.

CASE REPORT

We performed dermoscopy, high-frequency ultrasound (HFUS), in vivo and ex vivo reflectance confocal microscopy (RCM) of a pigmented CE arising on the caesarean scar of a phototype IV patient, along with histologic studies. Dermoscopy showed a greyish background and a brownish pigmentation. HFUS shows well-demarcated anechoic areas corresponding to ectopic endometrial tissue at histopathologic examination. RCM and OCT only showed the alterations of the epidermis.

CONCLUSION

High-frequency ultrasound could represent a very useful tool for an early diagnosis of CE and its usefulness could be tested in patients with unusual cyclical pain, even before skin lesion appearance. RCM allowed the visualization of skin surface modification due to underlying endometriosic tissue. Dermoscopy showed a new aspect that was probably related to the mix of blood extravasation (ie, greyish background) and epidermal pigmentation (ie, brown pigmentation).

An extremely rare case of gastric subepithelial tumor: gastric endometriosis

Endometriosis is a disease characterized by the presence of endometrial tissue outside of the uterine cavity. It is common in women of childbearing age, and is most frequently located in the pelvic cavity. Approximately 10% of endometriosis cases occur outside of the pelvic cavity in locations such as the intestines, genitourinary system, kidneys, lungs, and skin. However, there have been few reports of endometriosis in the stomach. Here, we report a rare case of endometriosis that presented as a subepithelial stomach tumor.

Surgical excision of umbilical endometriotic lesions with laparoscopic pelvic observation is the way to treat umbilical endometriosis

Primary umbilical endometriosis is extremely rare, although cases secondary to previous surgery have occasionally been reported. Here, we report three cases of umbilical endometriosis: two cases with previous cesarean section and one case of primary umbilical endometriosis. The treatment of choice for umbilical endometriosis is the excision of the lesions, and we believe laparoscopic pelvic observation is a beneficial addition, as 13%-15% of umbilical endometriosis cases are accompanied by pelvic endometriosis.
