The lesions were asymptomatic and neither bleeding nor painful. Her medical and surgical histories were unremarkable. HistologyHistopathological examination revealed a dermal proliferation of irregular glandular structures, surrounded by fibromyxoid and highly vascularized and edematous stroma with extravasated erythrocytes and a moderate infl ammatory

“Umbilical mass”: a case of primary umbilical endometriosis and literature review

“…The differential diagnosis of PUE includes benign and malignant conditions. Differential diagnoses of a recent onset umbilical nodule in a fertile woman includes benign disease such as purulent granulomas, umbilical polyps, dermatofibromas, neurofibromas, and keloid [10,16]. More importantly, keloid is clinically very similar to umbilical endometriosis.…”

Sister Mary Joseph nodule is a metastatic umbilical lesion present in 1-3% of patients with intra-abdominal or pelvic neoplasms.…”
