  1. 1.
    1872–
    In the genitive, attributive, and with of, esp. in Zenker's degeneration. Designating a type of degeneration affecting skeletal and cardiac muscle, in which fibres lose their striations and appear uniformly eosinophilic.
    Such degeneration was originally described in cases of typhoid fever, but also occurs in other infectious diseases and as a result of nutritional deficiency, toxin ingestion, etc.
    1. 1872
      Here and there some of the fibres presented the advanced condition of the waxy degeneration of Zenker.
      Transactions Clinical Soc. 1871–2 vol. 5 214
    2. 1898
      In Zenker's degeneration the muscular fibres themselves look dull and semi-opaque, and microscopically are found to have lost their striation.
      W. S. Lazarus-Barlow, Manual General Pathology xii. 521
    3. 1900
      The degeneration of the psoas muscle is quite analogous to the Zenker degeneration seen in typhoid fever.

    4. 1966
      Other findings in typhoid include..Zenker's degeneration of the abdominal muscles.

      Cases were further confirmed to suffer from AM [= atypical myopathy] on the basis of..histopathological findings showing a multifocal process compatible with Zenker's degeneration and necrosis in fibres of postural and/or respiratory muscles.

  2. 2.
    1897–
    In the genitive and attributive. Designating a type of diverticulum occurring at the junction of the pharynx and the oesophagus (pharyngo-oesophageal diverticulum).
    This type of diverticulum has also been called pulsion diverticulum, although pressure within the oesophagus is probably only one factor in its development.
    1. 1897
      Zenker's pressure diverticula arise from pressure from within, which causes a bulging outward of the œsophageal wall.
      B. T. Tilton, translation of H. Tillmanns, Text-book Surgery vol. II. 650
    2. 1932
      The symptoms of a Zenker pulsion diverticulum depend on the size of the pouch.
      Journal of American Medical Association vol. 98 965/2
    3. 1975
      A variety of neuromuscular disorders, with or without Zenker's diverticulum.

      The Zenker diverticulum typically arises from the posterior wall.
