Lymphomatoid granulomatosis, a rare condition in children, affects the lungs primarily but may have significant extrapulmonary manifestations, especially in the central nervous system. We report a case of lymphomatoid granulomatosis with onset after the completion of chemotherapy for childhood acute lymphoblastic leukemia. Two months after treatment ended, the 7-year-old girl developed
splenomegaly
, cervical adenopathy, and bilateral interstitial pulmonary infiltrates. She improved on cefotaxime but experienced a seizure 1 month later. A computed tomography scan of the head was normal, but her pulmonary infiltrates had become nodular. A computed tomography-guided biopsy of 1 of the nodules revealed cellular interstitial pneumonitis. One month later, she had persistent pulmonary infiltrates, marked
splenomegaly
, and new seizures. Magnetic resonance imaging of the head revealed cerebral nodules. Itraconazole was begun, and the pulmonary infiltrates resolved. Five months after her initial symptoms, she developed tonic pupil and a decreased level of consciousness.
Dexamethasone
was initiated. Needle biopsies of the brain were carried out, yielding the diagnosis of severe chronic inflammatory changes focally consistent with granuloma. The child redeveloped
splenomegaly
and fever, and then suffered an acute decompensation with hypoxemia, tachypnea,
splenomegaly
, and cardiac gallop. Open-lung biopsy revealed lymphomatoid granulomatosis. Lymphoma-directed therapy was initiated, and the patient had complete resolution of pulmonary and cerebral nodules 5 months later. No intrathecal chemotherapy was administered, and radiation therapy was not necessary. Neuropsychological testing obtained after completion of therapy revealed an improvement in attention, coordination, and fine motor speed over time. She is now in good health and attending school.

A 7-year-old previously healthy Czech boy was admitted due to fever, hepatosplenomegaly and pancytopenia. Aspiration of bone marrow revealed no signs of hemoblastosis (nor hemophagocytosis). He was treated with antibiotics and virostatics without effect. Progression of hepatosplenomegaly and pancytopenia induced suspicion of hemophagocytic lymphohistiocytosis (HLH). Five weeks later, bone marrow hemophagocytosis of erythrocytes, nuclear elements and platelets was detected. He was given corticoids and intravenous immunoglobulins and transferred to our haematology department. Laboratory findings of mild pancytopenia, hypofibrinogenaemia, hyperlipidaemia and elevated levels of ferritin, LDH and immunoglobulins were compatible to the diagnosis of HLH. Immunologic evaluation revealed T-lymphocyte activation. Appropriate immunosuppressive treatment with
Dexamethasone
, etoposide and Cyclosporine A was launched, followed by transient subside of fever and improvement of peripheral blood count, but not regression of hepatosplenomegaly. Four weeks later, relapse of fever and deterioration of blood count led to intensification of immunosuppression. However, no effect was evident. Moreover, hypertrophic cardiomyopathy with ventricular arrhythmia occurred. Treatment with antilymphocytic globulin for resistant course of HLH was planned. Before that, a fifth bone marrow aspiration was performed. Surprisingly, many Leishmania amastigotes were observed within marrow macrophages. Leishmania infection was confirmed by positive serology. Immunosuppressive treatment was withdrawn and changed for causal treatment with liposomal Amphotericin B. Positive clinical effect with subside of fever was evident in ten days,
splenomegaly
gradually resolved during three weeks, restoration of normal blood count lasted six weeks. No relapses of HLH nor leishmaniasis occurred. In control bone marrow aspirate performed three months later, the parasites were not detected. Ten months after the event, the patient is in complete remission of HLH with normal immunologic parameters. Most probably, he contracted visceral leishmaniasis during a visit of a Neapol area in Italy 3 months before the onset of the disease.

Here we present the case of a 57-years old patient affected by hemophagocytic lymphohistiocytosis (HLH), a rare disease characterized by an uncontrolled immune activation, resulting in clinical and biochemical manifestations of extreme inflammation. In a previous hospitalization, the patient showed fever, hepato-
splenomegaly
, pancytopenia, hyperferrtitinemia, lymphadenopathy and cholestasis. No diagnosis was done, however, he totally recovered after splenectomy. Eight months later, he relapsed, showing also hypofibrinogenemia, hypertriglyceridemia, hemophagocytic signs in bone marrow, cholestatic jaundice, high LDH and high PT-INR. Interestingly, he presented increased levels of amylase and lipase in absence of radiologic signs of pancreatitis. He was treated with
Dexamethasone
and Cyclosporine according to HLH-2004 guidelines. The clinical and biochemical manifestations disappeared in a few weeks, but he was newly hospitalized for lower limbs hypotonia caused by a hemophagocytic lesion of the cauda equina and lumbar cord. The death occurred in a few days, despite the immunosuppressive treatment.
