| Abstract

:
|
Leukemia cutis (LC) is a dermatologic manifestation of leukemia. Its clinical implications for the patient and the biological mechanism behind the manifestation of LC are unknown. The oncology community is increasingly utilizing mutations to classify a number of malignancies to prognosticate outcomes and to choose targeted therapies. A single-center, retrospective analysis of dermatopathology cases with a diagnosis of leukemia cutis was performed. Patients with genetic testing using the Columbia Combined Cancer Panel (a targeted sequencing protocol of 467 genes) or Genoptix (targeted sequencing protocol of 44 genes) were identified. The frequency of the presence of genetic mutations in LC patients was compared to AML patients from the COSMIC (Catalogue of Somatic Mutations in Cancer) database. Twenty nine cases were confirmed to have leukemia cutis, 22 of which had acute myeloid leukemia (AML). Genetic testing was available in 11 patients. Twelve different mutations were observed with particular enrichment for NPM1 and FLT3-TKD. Our original hypothesis was that patients with LC would display a distinct mutation profile. Ultimately, the distribution of mutations observed in our cohort of LC patients largely reflects the mutational profile seen in AML patients in general.
