Decidualized umbilical endometriosis

Abstract

A case of umbilical endometriosis is presented to highlight the challenges in its diagnosis. The etiology, clinical findings, histologic evaluation, prognosis and treatment options are discussed. While cyclic symptomatology may lend evidence to the diagnosis of umbilical endometriosis, history and clinical findings are often equivocal. Decidualization of umbilical endometriosis can be initially confused with a malignant process on histologic evaluation. The potential for malignant degeneration appears low. Surgical intervention is the treatment of choice.

Morphological variations of scar-related and spontaneous endometriosis of the skin and superficial soft tissue: A study of 71 cases with emphasis on atypical features and types of müllerian differentiations

“…[25][26][27][28] Its incidence in the Steck and Helwig series 2 was 9 of 82, while we have observed only one case among our 71 patients. Decidualized endometrium is due to the influence of ovarian and placental hormones, principally progesterone; thus it is commonly encountered in histologic specimens obtained during pregnancy or progestin therapy.…”

Cutaneous Inguinal Scar Endosalpingiosis and Endometriosis

“…15,39,50,51,59 There are also rare cases with decidual changes in epithelium and stroma. 5,11,16,40,46,50,59 Different types of metaplasia have also been reported. Tubal metaplasia is the most frequent change, and it has been presented with continuous cylindrical epithelium with cilia and peg cells.…”

“…It is usually present in patients with spontaneous rather than the scar endometriosis. 16,18,25,31,37,38,45,52 In the previously reported cases, the maximum diameter of the lesion with endometriosis ranged from less than 1 cm 4,9,13,21,35,52,54,56,57 to 9 cm 57 (average diameter was 2 cm), and in cases of endosalpingiosis, it spanned from 5 mm 61 to 2.7 cm. 1 In our case, the fragment in which endometriosis and endosalpingiosis were simultaneously found was 4 cm in its maximum diameter.…”

Umbilical laparoscopic scar endometriosis

“…However, umbilical endometriosis has low malignant potential. [4] Histopathology showed epidermis overlying the dermis containing endometrial glands, surrounded by edematous endometrial stroma with intravasated RBCs, congested blood vessels, lymphoplasmocytic infiltrate, and hemosiderin-laden hemorrhages confirming the diagnosis of scar endometriosis [Figure 4]. …”
