A 51-year-old female patient in the first chronic phase of CML received an allogeneic PBSCT from a matched unrelated donor. The transplant was manipulated by CD34+ cell selection. On day +193 after transplantation the patient was readmitted to the hospital with recurrent fever of unknown origin and cough. Clinical, radiographic and sonographic evaluation revealed no characteristic findings besides a mild splenomegaly. Screening for EBV, CMV, RSV and HSV did not indicate an active infection. On day +203 the patient developed generalized seizures, respiratory failure and died within 24 h in multiorgan failure. The macroscopic postmortem was still not enlightening; the histological examination however, demonstrated diffuse organ infiltration by monoclonal lymphoblastoid cells due to EBV-LPD.

A 65-yr-old man developed increasing dyspnea and fulminant respiratory failure 48 h after introduction of hydroxyurea, oral cytarabine ocfosfate (YNK01) and interferon-alpha for treatment of Philadelphia chromosome-positive chronic myelogenous leukemia. The chest radiograph showed bilateral patchy infiltrates while computed tomography revealed multiple bullas, ground glass opacities, and patchy consolidations with possible cavitation. Bronchoscopic examination was normal and microbiological tests performed on all biologic fluids were negative. The patient did not respond to multiple antibiotic treatment and corticosteroid administration and died of progressive respiratory failure 5 d after chemotherapy introduction. The postmortem lung examination was consistent with the diagnosis of bronchiolitis obliterans organizing pneumonia (BOOP).

We report the case of a 40-year-old female patient after allogeneic bone marrow transplantation due to chronic myeloid leukaemia. One year after transplantation, the symptoms of recurrent bronchial and lung infections, inefficiently treated with antibiotics, appeared. The disease was further complicated due to hepatic insufficiency resulting from mixed infection with HBV and HCV as well as because of chronic graft-versus-host disease (GvHD). Chest computed tomography and pulmonary function tests seemed to confirm BOOP diagnosis, but despite three-time-conducted bronchoscopy, histopathological diagnosis was not obtained. When admitted to the Pulmonary Department, the patient was in serious condition caused by intensifying respiratory failure. After multidrug therapy enabling to control opportunistic infections, high doses of corticosteroids were administered intravenously resulting in partial health improvement. The patient seems to be afflicted with BOOP of mixed aetiology. Treatment efficiency may confirm the necessity of rapid BOOP diagnosis even if histopathological diagnosis is not obtainable.

Pulmonary leukostasis is a rare but serious and often fatal complication of chronic myeloid leukemia (CML) in blast crisis and acute myeloid leukemia. Treatment options are limited for these patients. Imatinib mesylate (STI-571, Gleevec, Novartis) is a potent and selective inhibitor of the BCR-abl tyrosine kinase, the molecular abnormality that causes CML. The case of a 74-year-old man with a history of CML who presented in myeloid blast crisis with pulmonary leukostasis characterized by increasing dyspnea, hypoxemia, fever, and impending respiratory failure is reported. The patient was treated with single agent imatinib mesylate (IM) with rapid decrease in his white blood cell count (WBC) and marked improvement in his respiratory status. No electrolyte abnormalities consistent with tumor lysis syndrome were observed. IM may be an effective single agent therapy for pulmonary leukostasis in patients with CML blast crisis who are at the risk for tumor lysis.

A 74-year-old woman with chronic auricular fibrillation, arterial hypertension, hypercholesterolemia, ischemic cardiopathy, and peripheral arteriopathy presented with purpuric lesions on the lower limbs (Fig. 1) and, to a lesser extent, on the anterior area of the chest. The mucous membranes were not affected. In 1989, she was diagnosed with anemia that evolved until 1998, when a bone marrow biopsy revealed a myelodysplastic syndrome unclassified in French-American-British Group (FAB). The patient has required periodic transfusions since February 1999. A skin biopsy of the purpuric lesions revealed a leukocytoclastic vasculitis; the lesions cleared with topical corticosteroid treatment. In May 1999, the patient presented with inflammatory and painful lesions localized on the vulva (Fig. 2), which had evolved over several days, without fever. No lesions were observed in other locations. A cutaneous biopsy showed an intense dermal edema and a diffuse and polymorphous dermal infiltrate involving the follicular structures. Exocytosis, spongiosis, and mucin deposits, demonstrated by Alcian blue stain, were observed in the follicular epithelium. Mature neutrophils were predominant in the dermal infiltrate, but a small number of eosinophils and immature cells were also present (Fig. 3). The myelogenous origin of the immature lining cells was further confirmed by positive staining of intracytoplasmic granules with naphthol-ASD chloroacetate sterase (Leder's stain). Vasculitis was not observed. Routine laboratory tests revealed 3030 leukocytes/mm(3) (60% neutrophils), a hemoglobin level of 8.4 g/dL, and 92,000 platelets/mm(3). Treatment with 30 mg/day of prednisone was started, and the lesions cleared slowly within 4 weeks. A new bone marrow biopsy in September 1999 showed a similar appearance to that taken in 1998. The patient died in January 2000 as a result of pneumonia with cardiac and respiratory failure. A 66-year-old man presented with a febrile syndrome that had evolved over 5 days, and painful and pruritic cutaneous lesions on the face and posterior neck (Fig. 4). Three months before, the patient was diagnosed with chronic myelogenous leukemia in acceleration phase. Examination revealed an edematous and erythematous face with pustular lesions on the surface, also involving the neck and the upper part of the back. The histopathologic examination revealed an intense edema and abscesses in the dermis. The infiltrate of these lesions was composed of mature neutrophils with the presence of abundant immature cells with a myelogenous aspect (Fig. 5). Analytical studies revealed 26,130 leukocytes/mm(3) (42% blasts). No specific treatment for Sweet's syndrome was administered and the lesions showed an improvement within 5 days. Eight days after admission, the patient died as a result of acute hemorrhage, before treatment for leukemia was initiated.

Extramedullary myeloid tumors (myeloid sarcomas) are rare neoplasms that are composed of myeloid precursors. They usually arise concurrently with a diagnosis of acute myeloid leukemia, chronic myeloid leukemia, or other myeloproliferative disorders. They may also indicate relapsing disease in a patient with a prior history of leukemia or myeloproliferative disorder. We present our findings of a 63-year-old female diagnosed with extramedullary myeloid tumor first presenting in the gallbladder. She subsequently developed respiratory failure; pre- and postmortem bone marrow studies were negative for leukemia by morphology, flow cytometry, and karyotypic analysis. However, the myeloid neoplasm was disseminated throughout most of her remaining organs. Immunohistochemical stains of the cells indicated a neoplasm of myelomonocytic derivation (CD4, CD43, CD45, CD68, myeloperoxidase, and lysozyme positive). To our knowledge, this is the first report of an extramedullary myeloid neoplasm of the gallbladder with disseminated disease without involvement of the bone marrow.

Scedosporium prolificans is an emerging fungus that causes rapid progressive and disseminated infections in immunodepressed patients. We present a case of a 34-year-old woman with chronic myelogenous leukemia who received a bone marrow transplantation and suffered a sudden respiratory failure in +67 day. Chest radiographies showed growing bilateral patchy condensations. Computed Tomography depicted bilateral nodular condensation of alveolar space. S. prolificans was detected from sputum, but the patient died 72 h later. Imaging findings of lung scedosporiosis are nonspecific, but CT may provide a prompter diagnosis and allow to add newer antifungal treatments. This report presents the first imaging report of lung scedosporiosis.

We reported 5 patients who developed air-leak syndrome (ALS) including pneumothorax, pneumomediastinum and subcutaneous emphysema after allogeneic stem cell transplantation (SCT). The underlying diseases were AML (n=2), ALL (n=1), MDS (n=1), and CML (n=1). All patients received allogeneic SCT from related donors including 2 donors with HLA mismatch. Total body irradiation was performed as a conditioning regimen in all patients. Late-onset noninfectious pulmonary complications (LONIPC) were detected in all patients before the development of ALS. The interval from diagnosis of LONIPC to onset of ALS was 10-360 days (median, 20 days). Four of 5 patients were treated with corticosteroid for chronic graft-versus-host disease and/or LONIPC. To date, three patients have died of respiratory failure. The others are currently alive and one of these surviving patients is receiving home oxygen treatment. Physicians should be aware of this rare complication following LONIPC, because treatment of ALS is difficult in some patients.

Antineoplasic agent-induced pulmonary toxicity is an important cause of respiratory failure. These novel antineoplastic agents include imatinib mesylate, a protein tyrosine kinase inhibitor that is encoded by the Bcr-Abl gen created by the Philadelphia chromosome abnormality in chronic myeloid leukemia. Pulmonary toxicity of imatinib is directly related to the dose used. The more severe pulmonary manifestations include pleural effusion by water retention and interstitial pneumonitis. We report the first case published in Mexico ofimatinib-induced pulmonary toxicity and its management in the intensive care unit of the Medica Sur Clinic Foundation.

Pulmonary alveolar proteinosis (PAP) is a rare respiratory disease the character of which is accumulation of protein consisting of surfactant in alveolar spaces. PAP sometimes complicates with hematological malignancies, especially myeloid leukemia. As one of the cause of PAP, impairment of alveolar macrophage is considered. We experienced a case of PAP with chronic myeloid leukemia (CML). 41 years old woman having CML for nine years developed PAP, and was treated by bronchoalveolar lavage and imatinib. She died of respiratory failure in the end, but BAL fluid had been becoming gradually crystalline after induction of imatinib. We consider that we should try to treat to improve respiratory status not only PAP but also hematological disease.
