Tsanka cells

Tzang cells are special cells of the epidermis (outer layer of skin) that are one of the most characteristic features of various skin diseases. They have a characteristic appearance that includes a grainy and flaky layer of skin, as well as the presence of white or yellow blisters.

Most often, these cells are found in dermatological diseases such as psoriasis (irritated skin), atopic dermatitis (erythematous-flaky skin) and pityriasis versicolor (blistering lesions with a white discharge).

Because of its high specificity, visual identification of Tzang cells can be a fairly simple diagnostic test for various skin diseases. Diagnosis is carried out with the naked eye, but despite this simplicity, its accuracy reaches almost 10% in patients suffering from psriasis and almost 30% in atopic dermatitis. In this case, a positive Tzang cell test is especially useful in confirming the diagnosis and determining the severity of the disease.

Signs of Tzang cells in different skin diseases may vary depending on the etiology of the pathogenesis. For example, in pityriasis versicolor, the cells may be multiple, large blisters containing yellow or green exudate. With various types of psoriasis, subepidermal infiltrates are formed, and the so-called “psoriatic papule” is formed. Atopic dermatitis is characterized by flat, scaly features and thickening of the skin, with small papules and vesicles on the surface.

Traditionally, treatment for Tzang cells has included the use of topical and systemic corticosteroids, which can reduce the intensity of the skin reaction and reduce the number of cells. In addition, prolonged exposure to ultraviolet rays and skin stressors should be avoided to prevent symptoms from worsening.

In general, knowledge of Tzang cells has a special
