• mesenchymal
  • Mesenchymal neoplasms of the gallbladder are rare and in particular leiomyomas of the gallbladder have been rarely reported, all of them in patients with immune system disorders. (wikipedia.org)
  • A lineage relationship to other cell types has been proposed, including smooth muscle cells, neural cells, NG2 glia, muscle fibers, adipocytes, as well as fibroblasts and other mesenchymal stem cells, however whether these cells differentiate into each other is an outstanding question in the field. (wikipedia.org)
  • extraocular muscles
  • Visual impairment happens when the optic nerve is compressed or the extraocular muscles are surrounded. (wikipedia.org)
  • They include inflammation of the extraocular muscles (myositis) with tendinous involvement, orbital fat stranding, lacrimal gland inflammation and enlargement (dacryoadenitis), involvement of the optic sheath complex, uvea, and sclera, a focal intraorbital mass or even diffuse orbital involvement. (wikipedia.org)
  • lymphoma
  • For lymphoid neoplasms, e.g. lymphoma and leukemia, clonality is proven by the amplification of a single rearrangement of their immunoglobulin gene (for B cell lesions) or T cell receptor gene (for T cell lesions). (wikipedia.org)
  • vascular
  • Iridectomy - Removal of the affected piece of the iris Choroidectomy - Removal of the choroid layer (the vascular tissue sandwiched between the sclera and the retina) Iridocyclectomy - Removal of the iris plus the ciliary body muscle. (wikipedia.org)
  • genetic
  • Lung cancers are now considered a large and extremely heterogeneous family of neoplasms that feature widely varying genetic, biological, and clinical characteristics. (wikipedia.org)
  • occur
  • Even if the hypertrophy is bilateral, asymmetry of the face may still occur due to unequal enlargement of the muscles. (wikipedia.org)
  • neck
  • Muscles of the head and neck. (wikipedia.org)
  • Although it is mostly in the neck and can be grouped with the neck muscles by location, it can be considered a muscle of facial expression due to its common innervation. (wikipedia.org)
  • Masticatory muscles Facial nerve Facial Action Coding System Modiolus Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, page 89 Kyung Won, PhD. Chung (2005). (wikipedia.org)
  • Signs
  • However, no other signs are present except those involved in changes in occlusion intraorally such as pain, and the enlargement corresponds with the outline of the muscle. (wikipedia.org)
  • Mandibular
  • Along with the other three muscles of mastication (temporalis, medial pterygoid, and lateral pterygoid), the masseter is innervated by the anterior division of the mandibular division (V3) of the trigeminal nerve. (wikipedia.org)
  • In contrast, the nearby masticatory muscles are innervated by the mandibular nerve, a branch of the trigeminal nerve (cranial nerve V). The facial muscles are derived from the second branchial/pharyngeal arch. (wikipedia.org)
  • tissue
  • Additional symptoms included muscle atrophy in the legs and hands, deafness, cataracts, and a tissue mass covering the roof of his mouth. (wikipedia.org)
  • facial
  • The patient was a mentally retarded 43-year-old woman who had hearing impairment, distorted facial features, muscle atrophy, cataracts, and ossification of cartilage. (wikipedia.org)
  • The facial muscles are subcutaneous (just under the skin) muscles that control facial expression. (wikipedia.org)
  • The facial muscles are innervated by facial nerve (cranial nerve VII), with each nerve serving one side of the face. (wikipedia.org)
  • The stylohyoid muscle, stapedius and posterior belly of the digastric muscle are also innervated by the facial nerve, but are not considered muscles of facial expression. (wikipedia.org)
  • An inability to form facial expressions on one side of the face may be the first sign of damage to the nerve of these muscles. (wikipedia.org)
  • Damage to the facial nerve results in facial paralysis of the muscles of facial expression on the involved side. (wikipedia.org)
  • orbital
  • It can range from a diffuse inflammatory process to a more localized inflammation of muscle, lacrimal gland or orbital fat. (wikipedia.org)
  • Its former name, orbital pseudotumor, is derived due to resemblance to a neoplasm. (wikipedia.org)
  • cells
  • The first pericyte subtype (Type-1) can differentiate into fat cells while the other (Type-2) into muscle cells. (wikipedia.org)
  • patient
  • Place the fingers of each hand over the muscle and ask the patient to clench his or her teeth several times. (wikipedia.org)
  • described an adult male mentally retarded patient who had calcified pinnae and a neoplasm of the palate. (wikipedia.org)
