Tzanck cell definition of Tzanck cell by Medical dictionar

  1. The diagnostic cell (×400) is the multinucleated giant cell, an epithelial cell containing numerous nuclei, nuclear molding (clustered nuclei fitted to each other's shapes), and viral inclusions.
  2. The multinucleated cells are the diagnostic features of the historic Tzank test, a Giemsa stained smear of vesicle contents In the past, the laboratory diagnosis of herpes infection was confirmed by growth in tissue culture, electron microscopy, immunofluorescence of viral specific protein or viral DNA hybridization Varicella zoster
  3. A typical Tzanck cell [Figure - 1] is a large round keratinocyte with a hypertrophic nucleus, hazy or absent nucleoli, and abundant basophilic cytoplasm. The basophilic staining is deeper peripherally on the cell membrane (mourning edged cells) due to the cytoplasm′s tendency to get condensed at the periphery, leading to a perinuclear halo
  4. The Tzanck smear is most commonly used to diagnose cutaneous herpetic infections, but it leads to many false-positive and -negative results. This study aimed at establishing a method detecting much larger multinucleated giant cells using the Tzanck smear because these cells characterize the viral cytopathic effect in skin infections
  5. The characteristic finding of herpetic infection in the Tzanck smear test is acantholytic cells with multinuclear giant cells 2. Another disease that is related to these cells is pemphigus

A typical Tzanck cell is a large, rounded keratinocyte with a hypertrophic nucleus, hazy or absent nucleoli and abundant basophilic cytoplasm, which is deeper peripherally on the cell membrane due to cytoplasmic condensation at the periphery, leading to a perinuclear halo The finalized model was evaluated using a prospective validation dataset of 359 Tzanck smear images collected from 15 patients during January 2020. It is designed to recognize six cell types (acantholytic cells, eosinophils, hypha, multinucleated giant cells, normal keratinocytes and tadpole cells) Giemsa staining for the Tzanck test is time-consuming and laborious.

A Tzanck cell is a large round keratinocyte with a hypertrophic nucleus, hazy or absent nucleoli, and abundant basophilic cytoplasm.
