title: Specific cutaneous lesions of the scalp in myelodysplastic syndrome with deletion of 20q.
abstract: We reported a specific skin lesion on the scalp in a patient with myelodysplastic syndrome (MDS), treated as refractory anemia with excess of blasts (RAEB). Histologically, a specimen from a nodule of the scalp consisted of a diffuse infiltration of atypical cells in the dermis and subcutaneous tissue. The patient died of acute leukemia 3 months later. Chromosomal examination of bone marrow cells revealed deletion of 20q and 21 trisomy. The specific cutaneous lesions in this patient were associated with acute transformation. The deletion of 20q and specific cutaneous lesions are regarded as signs of poor prognosis.
