Unusual patterns of presentation of acute leukemia are discussed, with an emphasis on the diagnostic and therapeutic challenges that they pose. Clinical syndromes reviewed include the leukostasis syndrome, disseminated intravascular coagulation, granulocytic sarcoma, central nervous system leukemia, leukemia cutis, Sweet's syndrome, pyoderma gangrenosum, and acute leukemia diagnosed during pregnancy. Each of these uncommon presentations of acute leukemia has a unique impact on patient management.

A case of Sweet syndrome (SS) associated with acute megakaryoblastic leukemia (AMKL) is reported. A 66-year-old male was admitted to Ashikaga Red Cross Hospital because of skin eruption and sore throat. His eruption was tender and erythema-like nature. He developed a spiking fever after admission. CBC revealed pancytopenia, and a bone marrow specimen showed increased megakaryoblasts and fibrosis. These blasts were shown to be CD41-positive by flow cytometric analysis. A diagnosis of AMKL was then made. Skin biopsy revealed infiltration of neutrophils without vasculitis, compatible with SS. Oral administration of prednisolone was begun which improved his skin lesions considerably. He was then treated with low dose Ara-C, which was however ineffective. The blasts increased in the peripheral blood and he died on the 72nd hospital day. There are 37 reported cases of SS associated with acute nonlymphocytic leukemia, and this is the first case report of SS associated with AMKL.

We report a 58-year-old patient with acute myeloid leukaemia who developed an oedematous erythema resembling Sweet's syndrome, accompanied by atypical erythema nodosum and bullous pyoderma gangrenosum. Examination of skin biopsies showed dense infiltration with mature neutrophils, although there was peripheral blood leucocytopenia. The oedematous erythema worsened after he was treated with granulocyte-colony-stimulating factor (G-CSF), which was given for his leucocytopenia. We suggest that when a neutrophilic dermatosis complicates leukaemia, alternatives to G-CSF should be considered for the treatment of leucocytopenia. Corticosteroids were very effective in controlling the skin lesions in our patient.

Induction therapy of promyelocytic leukemia with all-trans retinoic acid is a standard therapy despite significant side-effects. The most important, the "retinoic acid syndrome", consists of a hyperinflammatory reaction with capillary leakage (edema, pleural, and pericardial effusion), infiltration of myeloid cells into internal organs and systemic signs of inflammation. We describe here two cases of another hyperinflammatory reaction during all-trans retinoic acid therapy, the Sweet's syndrome, consisting of infiltrates of the skin and internal organs by neutrophilic granulocytes. Fever, painful erythematous cutaneous plaques, prominent musculoskeletal involvement (myositis, fasciitis), a sterile pulmonary infiltration and intercurrent proteinuria characterized the clinical course of all-trans retinoic acid-associated Sweet's syndrome. Treatment with glucocorticoids led to resolution of the syndrome within 48 h. Three other cases of all-trans retinoic acid-associated Sweet's syndrome without involvement of internal organs, prominent on our cases, were published previously. Recognition of ATRA-associated Sweet's syndrome is of practical importance.

Neutrophilic dermatosis (Sweet syndrome) is a rare condition characterized by painful indurated cutaneous plaques infiltrated with mature neutrophils and may be accompanied by fever, granulocytosis, arthritis, and conjunctivitis. It is associated with various malignant and preneoplastic states, the most common being leukemia and myeloproliferative disorders. Its association with solid tumors is infrequent. The case described here represents, to our knowledge, the first report of Sweet syndrome in a patient with osteogenic sarcoma, a primary tumor of bone arising from mesenchymal cells.

Several adverse effects have been reported to occur after clinical application of all-trans retinoic acid (RA) in acute promyelocytic leukemia (APL). Except for severe side effects including retinoic acid syndrome, the mechanism of action of RA on adverse effects remains unclear. Here we describe some rare adverse effects and their management. We reviewed the English literature, and we added our cases of endocrine and metabolic adverse effects, such as hypercalcemia, male infertility, bone marrow necrosis, fibrosis and acute pancreatitis. We also described our cases of thromboembolic events, RA-dependent growth of pathologic cells including Sweet's syndrome, erythema nodosum, hyperhistaminemia, granulomatous proliferation, and mild cases of pulmonary complications. In addition, we reviewed the efficacy of RA administration for other types of leukemia or myelodysplastic syndrome. RA and chemotherapeutic agents might induce complete remission, but we obtained a response in only one case of M2 in the third relapse. During RA administration the patient should be monitored for these adverse effects, and early diagnosis and appropriate treatment are important.

Seven patients with Sweet's Syndrome (SS) accompanying leukaemia are presented. Six had acute myeloid leukaemia and one chronic myeloid leukaemia. SS developed during G-CSF therapy in two patients and following long periods of chemotherapy-associated neutropenia in two. This finding may suggest a possible role of G-CSF in the pathogenesis of SS. SS was diagnosed during the first presentation of three patients with leukaemia. Skin lesions on the lower extremities in two patients, widespread distribution in one, a local infiltration at the inguinal region and pleural effusion in one were interesting findings in our patients which are not usual for classical SS.

Sweet's syndrome, or acute febrile neutrophilic dermatosis, is a condition characterized by the sudden onset of fever, leukocytosis, and tender,erythematous, well-demarcated papules and plaques which show dense neutrophilic infiltrates on histologic examination. Although it ma occur in the absence of other known disease, Sweet's syndrome is often associated with hematologic disease (including leukemia), and immunologic disease (rheumatoid arthritis, inflammatory bowel disease). Treatment with systemic corticosteroids is usually successful. skin, Sweet syndrome, neutrophilic dermatosis, corticosteroids,

2-Chlorodeoxyadenosine (2-CdA) is associated with prolonged suppression of CD4 lymphocytes. Cases of tuberculosis or mycobacterium avium intracellulare complex (MAC) infection complicating 2-CdA administration have not been reported despite the low CD4 counts. We report a patient with Hairy Cell Leukaemia (HCL) who developed MAC infection one month following 2-CdA treatment. This patient had been previously treated with prednisone for Sweets Syndrome. It would appear that the combination of 2-CdA and prednisone predisposes patients to MAC infection, and if possible this combination of treatment should be avoided.

Sweet's syndrome is associated with haematological malignancy, particularly acute myelogenous leukaemia, but there are few reports of its association with polycythaemia rubra vera. We describe an 85-year-old man with polycythaemia rubra vera who developed Sweet's syndrome and review the literature of this association.
