The lesion was a shiny reddish-brown nodule, measuring 3cmx3cm, painful to the touch and that alternated in size since its onset (Figure 1).
Umbilical endometriosis. Dermoscopic aspect by epiluminescence microscopy. 10x magnification. Number 1: a regular pigmented network is noticed in its central area. Number 2: an amorphous brown area with white scar tissue in the center, caused by a biopsy procedure. Number 3: a homogeneous reddish pigmentation is regularly distributed

It showed homogeneous reddish localized pigmentation, with no differentiated structures. In addition, an amorphous brown area was present, where normal skin network was more evident in some parts (Figure 2).
Umbilical endometriosis. Histopathological aspect. Stained by Hematoxylin and Eosin (HE). On left lower portion, epidermis with discrete acanthosis. In the dermis, a myxoid stroma aspect with fibroblastic proliferation, evidenced by the spinde-shaped cells. On the upper right portion, glandular type cells, characteristic of endometriosis

The biopsy revealed fibroblastic proliferation in the dermis and endometrial glandular tissue, of the decapitation secretion type (Figures 3 and 4).
Umbilical endometriosis. Histopathological aspect, stained by Hematoxylin and Eosin (HE). The upper right portion of the first histopathological picture shows a higher approach to the decapitation secretion of the glandular cells. These features belong to the secretory phase of the glandular epithelium
