Clinical InformationClinical

  • Ganglioneuroma

    a benign neoplasm that usually arises from the sympathetic trunk in the mediastinum. histologic features include spindle cell proliferation (resembling a neurofibroma) and the presence of large ganglion cells. the tumor may present clinically with horner syndrome or diarrhea due to ectopic production of vasoactive intestinal peptide. (from devita et al., cancer: principles and practice of oncology, 5th ed, p966)

  • Horner Syndrome

    a syndrome associated with defective sympathetic innervation to one side of the face, including the eye. clinical features include miosis; mild blepharoptosis; and hemifacial anhidrosis (decreased sweating)(see hypohidrosis). lesions of the brain stem; cervical spinal cord; first thoracic nerve root; apex of the lung; carotid artery; cavernous sinus; and apex of the orbit may cause this condition. (from miller et al., clinical neuro-ophthalmology, 4th ed, pp500-11)

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
