case_images: Physical examination revealed that a black linear lesion of 4 cm in length was inside the skin on the right mandibular angle, associated with edematous erythema around (Figure 1a). By pulling the outside part with a needle, the distal end of the black line was easily taken out without association of bleeding; however, the proximal part was still in the skin (Figure 1b). Then the black thread was forcibly extracted from the skin with forceps (Figure 1c) that was demonstrated a hair under microscope.
