We have observed two cases of staphylococcal myositis in patients with acute lymphocytic leukemia which are distinguished from previously reported cases by a history of cutaneous vasculitis overlying the area of subsequent infection.

Erythematous macules, nonpalpable and palpable purpura, and flaccid pustules developed in a 59-year-old man with acute lymphocytic leukemia 8 days after reinduction chemotherapy with cytosine arabinoside and daunorubicin. Tissue and blood cultures grew Fusarium proliferatum, and a skin biopsy specimen revealed fungal vasculitis. Anemia and muscle weakness accompanied the disseminated infection, for which the patient received granulocyte transfusions and amphotericin B, ketoconazole, rifampin, and griseofulvin. Skin lesions and fungemia resolved with recovery of the bone marrow, and 51 days after the completion of his chemotherapy he returned home. If promptly recognized and aggressively treated, disseminated fusariosis is responsive to therapy. Infection with Fusarium species should be suspected in profoundly neutropenic patients in whom disseminated palpable purpura and myositis develop concomitantly.

A 14-year-old child with acute lymphoblastic leukemia who had completed induction chemotherapy presented with fever and diffuse musculoskeletal pains which was thought to be a constellation of myositis, arthralgias and arthritis. Investigations revealed initially showed normal peripheral blood counts but had pancytopenia and pre-terminally blasts were seen in the peripheral blood smear. He had bone marrow necrosis. Disseminated intravascular coagulation was suspected with a positive fungal serology. At autopsy, he had evidence of disease relapsed in lymph nodes, liver, spleen, testes and kidneys. There was extensive pseudomembranous colitis and appendicitis with changes of toxic megacolon.

The relationship between primary hematologic disease and rheumatologic manifestations is well known, especially acute lymphocytic leukemia, lymphomas, plasma cell dyscrasias and myelodysplastic syndrome (MDS). Currently, more has been described about autoimmune manifestations in chronic myelomonocytic leukemia (CMML). Many different clinical scenarios may lead a patient with MDS/CMML initially to seek a rheumatological unit. Autoimmune features such as polymyalgia rheumatic symptoms, myositis, neutrophilic dermatosis, cutaneous vasculitis and positive antinuclear antibodies (ANA) are some examples of clinical presentation of MDS/CMML. Moreover, peripheral cytopenias are a common initial presentation both for systemic lupus erythematous (SLE) and MDS/CMML. The aim of this study was to describe a case of an elderly woman with thrombocytopenia and positivity of antibodies to anti-extractable nuclear antigens (anti-ENA) as initial manifestation of CMML mimicking SLE, and to present some clues that encourage the clinician to perform a bone marrow study in such a clinical scenario.
