Armillifer armillatus parasite imaging in case of human infection mimicking strangulated umbilical hernia, France, 2026. A) Perioperative macroscopic photograph of the umbilical subcutaneous cyst and parasite. B) Gross appearance of the extracted nymph indicating its cylindrical shape and cuticular annulations. Scale bar = 1 cm. C) Microscopic view of the body wall showing cuticular openings. Scale bar = 50 μm. D) Thoracoabdominal computed tomography showing a 15-mm subcutaneous cyst (arrow) with surrounding fat stranding and no visible C-shaped calcifications.
