Abstract: Indeterminate dendritic cell tumor (IDCT) is an extremely uncommon histiocytic and dendritic neoplasms subtype that presents as single or multiple papules. There is currently no standard method for diagnosis and treatment, and the selection of therapeutic approaches is mainly based on successful examples of folk medicine. We describe a case of a pathology diagnosed indeterminate dendritic cell tumor, which shows the presence of CD1a, S100, and CD68, but lack langerin. She was treated with multi-chemotherapy regimens used to treat lymphoma and gained good results short term but was easy to recur. In addition, we reviewed the literature on the effectiveness and safety of chemotherapy in IDCT patients.
