case_images: Examination of the nose revealed a firm and lobulated mass located in the lateral part of the right ala nasi, of approximately 2 cm x 1 cm in size, covered by an adherent and thinned skin, extending into the nasal vestibule (Figure 1).

case_images: Anterior rhinoscopy found a whitish nonobstructive mass, not bleeding on touch, covered by a normal vestibular skin (Figure 2).

case_images: fig3-1179550619886561
case_images: The tumor was carefully dissected without damaging the capsule, but due to its adherence to the ala nasi skin, it was necessary to remove the tumor along with the covering skin (Figure 3).
case_images: Histopathologic photomicrograph showing epithelial and myoepithlial cells in
  myxoid stromal component (H&E; x200). Blue arrow indicates fibrous
  capsule; red arrow, mesenchymatous component; yellow arrow, epithelial and
  myoepithelial component.

case_images: fig4-1179550619886561
case_images: On histologic examination, the tumor was composed of a mixture of calcified ductal and tubular formations and spindle myoepithelial cells into chondromyxoid stroma (Figure 4).
case_images: Immunohistochemistry photomicrograph revealing myoepithelial cells with
  positive cytokeratin 7 expression (red arrow) (H&E; x400).
