case_images: A 73-year old male patient presented with an asymptomatic erythematous nodule (0.8 x 0.6 x 0.5 cm in size) in the right inframandibular region for about a year (Figure 1).
case_images: A) nodules of varying sizes with large amounts of mucin and
  stellate cells (Hematoxylin & eosin x20); B) detail of
  stellate cells (Hematoxylin & eosin x200)

case_images: After surgical excision with 3-mm margins, pathological studies showed multiple nodules of varying sizes, containing abundant mucin and sparse stellate cells in the dermis, consistent with myxoid neurothekeoma (Figure 2).
case_images: Immunohistochemistry: A) positivity for vimentin (Hematoxylin
  & eosin x200); B) positivity for CD-68 (Hematoxylin &
  eosin x40); C) negativity for S-100 in tumor cells and
  positivity in the nerve (Hematoxylin & eosin x100); D)
  negativity for EMA (Hematoxylin & eosin x20)
