Clinical features
This section has been translated automatically.

Occurrence of dermatological symptoms usually only after clinical diagnosis. Skin symptoms are rarely observed as a primary manifestation of the disease.
  • Lymphatic leukemia (more than 90% B-cell type, approx. 10% T-cell type):
  • Myeloid leukaemia:
    • Specific skin symptoms (relatively rare): plate-like to nodular infiltration of the skin.
    • Non-specific skin lesions: paleness in secondary anaemia, bleeding in the skin and mucous membranes with a tendency to ulcerous-necrotic transformation, especially in acute myeloid leukaemia; generalised pruritus, prurigo simplex subacuta, macular, nodular, figured erythema; erythrosquamous or vesiculobullous eruptions; very rarely universal non-specific erythroderma.
  • Immature, acute leukoses (myelo- or paramyeloblastic leukemia)
    :Thrombopenic purpura, development of necroses with a tendency to disintegrate in the oral cavity, genital and anal area (by accompanying granulocytosis), candidiasisof
    the mucous membranes, gingival hyperplasia, possibly generalized lymph node enlargement.
