Clinicopathologic Spectrum of Dermatological Diseases in Patients with Acute Myeloid Leukemia (AML): A Retrospective Study in AML Patients with Cutaneous Manifestations.

Leukemia is one of the most common hematological malignancies. Cutaneous manifestations of leukemias consist of two groups: specific and non-specific. While the drug reactions, opportunistic infections due to myelosuppression are non-specific skin findings of leukemias, leukemia cutis is a specific sign of cutaneous involvement. In this retrospective study, we included patients over the age of 18 who were diagnosed with acute myeloid leukemia (AML) and underwent histopathological examination due to dermatological complaints. A total of 21 patients were included. Histopathological examination results were consistent with myeloid sarcoma, erythema nodosum, cutaneous drug eruption, necrosis due to vascular damage, cutaneous vasculitis, graft versus host disease, Sweet syndrome and viral infection. Dermatological examination plays an important role in AML patients. Skin biopsy and immunohistochemical examination should be performed to make early diagnosis of skin metastasis of leukemias and paraneoplastic syndromes to reduce the mortality and morbidity in AML patients.
