Abstract
A 28‐year‐old Caucasian woman presented with a nodule in the umbilicus at week 12 of pregnancy. She had a 2‐year history of intermittent pain and bleeding from the umbilicus. The lesion also bled during pregnancy. Examination revealed a tender, reddish‐brown polypoid nodule, 1 × 1 cm in diameter, in the umbilicus (Fig. 1). Medical and surgical history revealed nothing of note. Histological examination of a haematoxylin and eosin‐stained biopsy specimen showed a mass of polygonal cells with abundant cytoplasm rich in eosinophils and spaces lined with flat and, in places, simple cuboid epithelial cells in the dermis (Fig. 2).
