Lamellar corpuscles, or Pacinian corpuscles, are one of the four major types of mechanoreceptor.They are nerve endings in the skin responsible for sensitivity to vibration and pressure. More particularly, they are primarily located just beneath the epidermis within the dermal papillae. The rate at which they are lost correlates well with the age-related loss in touch sensitivity for small probes. Pacinian corpuscles Meissner's corpuscles Merkel cells proprioceptors . They have been described nearly exclusively in peripheral nerve sheath tumors, namely diffuse neurofibromas, and schwannomas but also in cellular nevi.
