Leukemia Cutis Presenting as a Morbilliform Eruption: A Case Report and Literature Review.

Leukemia cutis (LC) is a broad term that describes the infiltration of neoplastic leukocytes into the skin. Classically, LC is characterized by erythematous papules and nodules. However, LC can have a widely variable presentation. Therefore, it is crucial to maintain a high index of suspicion for LC through a complete clinical assessment, histopathology, and immunohistochemistry to distinguish this entity from other clinical mimickers. Herein, we report a case of biopsy-proven LC presenting as a morbilliform eruption that was initially suspected to be a drug eruption in a child with acute monocytic leukemia.
