EtiopathogenesisThis section has been translated automatically.
Clonal growths of the leukopoietic, myeloid or lymphatic system.
Clinical featuresThis 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):
- Specific skin symptoms (in 10% of patients): Generalized swelling of lymph nodes and leukemic exanthema: Red to red-blue, possibly maculopapular efflorescences, flat to bulbous, coarse infiltrates, especially in the area of forehead, cheeks, nose and ears. Cutaneous tumours also occur, in some cases the tumours and infiltrates conflate to form facies leontina. Furthermore: Lymphadenosis cutis circumscripta.
- Non-specific skin symptoms (leukaemids, in 28% of patients): pruritus, prurigo, chronic urticaria, petechiae, purpura, ecchymosis, zoster generalisatus, herpes simplex.
- 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.
DiagnosisThis section has been translated automatically.
Blood count, sample excision with histology and immunohistology, chromosome analysis (in chronic lymphatic leukemia in approx. 90% Philadelphia chromosome).
TherapyThis section has been translated automatically.
Treatment of the underlying disease by haematooncologists. Treatment of skin changes depending on the clinic.
