Male and female patients must use an effective contraceptive method during the study and for a minimum of 6 months after study treatment.\n* Capable of understanding the investigational nature, potential risks and benefits of the study, and able to provide valid informed consent.\n* Participants must have adequate marrow functions as defined below, except those with involvement of hematopoietic system for whom these criteria can be waived:\n\n * Absolute neutrophil count ≥ 750 cells/µL\n * Platelets ≥75,000/µL\n* Participants must have adequate organ functions as defined below:\n\n * Total bilirubin ≤ 2.5x institutional upper limit of normal\n * AST (SGOT)/ALT (SGPT) \\< 2.5 X institutional upper limit of normal unless it is related to involvement by LCH\n * Adequate renal function defined as:\n * Pediatric Population (patients \\< 18 years): Creatinine within normal limits or calculated creatinine clearance greater than or equal to 90 ml/min/1.73 m2 as calculated by the Schwartz formula for estimated glomerular filtration rate (GFR) where GFR (ml/min/1.73 m2) = k x Height (cm)/serum creatinine (mg/dl). k is a proportionality constant which varies with age and is a function of urinary creatinine excretion per unit of body size; 0.45 up to 12 months of age; 0.55 children and adolescent girls; and 0.70 adolescent boys.\n * Adult Population (patients \\>= 18 years): Serum creatinine less than or equal to 1.0 mg/dL; if serum creatinine \\>1.0 mg/dL, then the estimated glomerular filtration rate (GFR) must be \\>60 mL/min/1.73 m2 as calculated by the Modification of Diet in Renal Disease equation where Predicted GFR (ml/min/1.73 m2) = 186 x (Serum Creatinine)-1.154 x (age in years)-0.203 x (0.742 if patient is female) x (1.212 if patient is black), where serum creatinine is measured in mg/dL.\n * Alkaline phosphatase ≤ 2.5 x institutional upper limit of normal\n\nExclusion Criteria:\n\n* Participants who have had chemotherapy or radiotherapy within 2 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 2 weeks earlier. Corticosteroid treatment is allowed.\n* Participants may not be receiving any other investigational agents targeting Histiocytosis.\n* Clofarabine is excreted primarily by the kidneys.

Because there is an unknown but potential risk of adverse events in nursing infants secondary to treatment of the mother with clofarabine, breastfeeding should be discontinued if the mother is treated with clofarabine. These potential risks may also apply to other agents used in this study.\n* Individuals with a history of a different malignancy are ineligible except for the following circumstances. Individuals with a history of other malignancies are eligible if they have been disease-free for at least 5 years and are deemed by the investigator to be at low risk for recurrence of that malignancy. Individuals with the following cancers are eligible if diagnosed and treated within the past 5 years: cervical cancer in situ, and basal cell or squamous cell carcinoma of the skin.\n* Patients with a history of prior hematopoietic stem cell transplantation (HSCT), elevated conjugated serum bilirubin at study entry, uncontrolled systemic fungal, bacterial, or other infection, a history of hepatitis B or C infection or a history of cirrhosis.\n* Individuals who are known to be HIV-positive on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with clofarabine. In addition, these individuals are at increased risk of lethal infections when treated with marrow-suppressive therapy.
