“…In another patient with MTOE in the abdominal wall, the SUVmax on 18 F-FDG PET/MRI was 9.61 in the abdominal wall and 4.25 in metastatic retroperitoneal and inguinal lymph nodes. 32 In the case reported by Yoshida et al, 31 18 F-FDG was taken up by MTOE in the groin, as well as by ipsilateral metastatic pelvic lymph nodes in a postmenopausal patient, but the 18 F-FDG uptake values were not provided.…”

Introduction: Endometriosis is a common gynecologic condition that may be visualized on 18 F-FDG PET/CT and mimic lesions of malignancy. We analyzed the interference of known or suspected endometriosis in reporting 18 F-FDG PET/CT performed in another indication. Results: The PET/CT images of 18 women with known (n = 15) or suspected (n = 3) endometriosis were analyzed. Based on clinical follow-up and results of other imaging, biopsy, and/or postsurgical histology, the presence of lesions of endometriosis at the time of 18 F-FDG PET/CT was confirmed in 13 of 18 patients (72%). The per-patient positivity rate of 18 F-FDG PET/CT was 8/18 (44%; 95% confidence interval, 22%-69%). The patient-based detection rate of 18 F-FDG PET/CT in patients with confirmed lesions of endometriosis was 8/13 (62%; confidence interval, 32%-86%). On per-lesion/site basis, 18 F-FDG PET/CT detected 11 of 20 sites (55%) of endometriosis. The SUVmax of these lesions/sites ranged between 1.8 and 5.3 (median, 3.8). In 9 of 18 patients (50%), a total of 13 non-endometriosis-related lesions/sites were detected by 18 F-FDG PET/CT; their SUVmax ranged between 2.7 and 23 (median, 9.4). Conclusion:The interference of known or suspected endometriosis in reporting 18 F-FDG PET/CT performed in another indication was limited but possible and should be kept in mind, even in postmenopausal women, as the oldest patient with 18 F-FDG-positive endometriosis was aged 63 years. The lesions of endometriosis showed inconstant 18 F-FDG uptake with overlap of SUVmax with low-grade malignancies. In our series, the greatest SUVmax value of lesion of endometriosis was 5.3, somewhat higher than the threshold of 4 previously proposed for identification of malignant transformation of endometriosis.

“…TC și IRM de rutină nu sunt sensibile în detectarea malignizării, la moment nu există un marker clinic specific pentru determinarea transformării maligne a EO [57]. Pozitronul 18F-fluorodeoxiglucoză tomografie cu emisie/tomografie computerizată (18F-FDG PET/ TC) s-a dovedit a fi o modalitate de imagistică sensibilă și bine stabilită pentru detectare, stadializare, restadializare și evaluarea răspunsului terapeutic al tumorilor maligne [57]. Tomografie simultană cu emisie de pozitroni 18F-FDG/ imagistică prin rezonanța magnetică (PET/IMR) are potențialul de a reprezenta un rol important în identificarea malignizării și evaluarea stadializării clinice, deoarece IRM are un contrast mai mare al țesuturilor moi și fără expunere majore la radiații ionizante în comparație cu TC [57].…”

“…Incidența transformării maligne a endometriozei cutanate raportată în literatura de specialitate constituie 0.3%-1% cazuri [32,53,55]. Transformarea malignă în regiunea cicatricei postoperatorii a peretelui abdominal, este o evoluție extrem de rară, cu mai puțin de 30 de cazuri raportate în literatura de specialitate la nivel mondial [53,55,57]. Structura morfologică a acestor cazuri a fost: carcinom endometrioid (70%), sarcom (25%) și carcinom cu celule clare (5%) [54].…”

“…Structura morfologică a acestor cazuri a fost: carcinom endometrioid (70%), sarcom (25%) și carcinom cu celule clare (5%) [54]. Cu toate că EO este o patologie benignă, există riscul minimal al malignizării, care trebuie de luat în considerație pentru sporirea vigilenței de diagnostic timpuriu al acestei patologii [51,[53][54][55]57].…”

Umbilical endometriosis. Umbilical endometriosis (UE) is attributed to the rare forms of extragenital endometriosis presented in the literature through unique clinical trials or limited series. UE is a very rare condition with an estimated prevalence of <1% of all ectopic endometriosis. The first description of a primary umbilical endometrioma is credited to Villar in 1886, hence the term Villar’s nodule. UE is even more difficult to diagnose due to the extreme lack of clarity in clinical signs. Given the location of the given pathology, a differential diagnosis with other umbilical surgical diseases is necessary. A review of the literature of the last 10 years was generated based on PubMed and Google Scholar research, selecting some specific keywords. Several lesions can occur in the umbilical region, and endometriosis has to be ruled out even in patients without any surgery in their medical history. Surgery is the gold standard treatment for this condition. Considering the multitude of pathologies of the umbilical region that may look similar to EO, this condition must be considered in the differential diagnosis. Radical surgical excision is the preferred treatment aimed at preventing recurrence and reducing the risk of malignant transformation.
