Successful 5-azacytidine treatment of myeloid sarcoma and leukemia cutis associated with myelodysplastic syndrome: A case report and literature review

Rationale: Myeloid sarcoma (MS) and leukemia cutis (LC) are extramedullary tumors comprising myeloid blasts. They can occur de novo or concurrently with hematological disorders, usually acute myeloid leukemia (AML). AML chemotherapy is generally the initial therapy for MS and LC, and hematopoietic stem cell transplantation (HSCT) can be considered as additional therapy. However, treatment for older patients who are unable to continue intensive chemotherapy is not currently standardized. Patient concerns: A 71-year-old Japanese woman was diagnosed with multiple MSs associated with myelodysplastic syndrome (MDS), using bone marrow aspiration and lymph node biopsy. Diagnoses: Additionally, LC was diagnosed by skin biopsy. Extramedullary MS and LC lesions were formed by massive infiltration of myeloblastic cells. Interventions: Twenty courses of 5-azacytidine (5-Aza) were administrated as maintenance therapy after induction therapy with daunorubicin and cytarabine. Outcomes: Myeloblasts decreased in the bone marrow and the LC disappeared after induction therapy. The MSs completely disappeared, except for the palatine tonsil lesion, after 5-Aza maintenance therapy. 5-Aza treatment provided long-term partial response for more than 21 months. Lessons: 5-Aza was well tolerated and may be a good option for the treatment of MS and LC associated with MDS, especially in older patients who cannot receive HSCT.

We report a myelodysplastic syndrome (MDS) patient who presented Fusarium solani infection associated with granulocytic sarcoma as an initial presentation of acute myeloid leukemia (AML) transformation. We performed histological examination, immunohistochemistry analysis, culture of the biopsy tissue and DNA sequencing to make a conclusive diagnosis of F. solani and granulocytic sarcoma, reinforcing the necessity of performing complete evaluation of skin lesions in immunocompromised patients.

We report a case of myeloid sarcoma with megakaryoblastic differentiation in the breast of a patient with history of essential thrombocythemia. The mass was composed of undifferentiated pleomorphic malignant cells in trabecular cords and nests with many scattered giant malignant cells and brisk abnormal mitoses. On immunohistochemistry, the neoplastic cells were positive for CD61, CD31, CD34, Factor VIII and CD43 which confirmed the diagnosis. To our knowledge, this is the first report of myeloid sarcoma with megakaryoblastic morphology occurring in the breast. Here we discuss the clinicopathologic features of this rare en...

ConclusionDe novo myeloid sarcoma mostly presented isolated. Lesions were often localized at skin and lymph nodes. Genetic aberrations frequently involved coreā€binding factor rearrangements in de novo cases and a complex karyotype in secondary cases.This article is protected by copyright. All rights reserved.

Purpose of review Recurrent loss of function mutations within genes of the cohesin complex have been identified in myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). STAG2 is the most commonly mutated cohesin member in AML as well as solid tumors. STAG2 is recurrently, mutated in Ewing's Sarcoma, bladder cancer, and glioblastoma, and is one of only ten genes known to be recurrently mutated in over four distinct tissue types of human cancer Recent findings The cohesin complex, a multiprotein ring, is canonically known to align and stabilize replicated chromosomes prior to cell division. Although initially...

Conclusion Bendamustine is an effective therapy with limited long-term sequelae in patients with lymphoid malignancies. Micro-Abstract Bendamustine is an effective treatment for lymphoid malignancies and its role continues to expand. To determine the long-term sequelae associated with bendamustine, 194 patients treated with bendamustine (most commonly with rituximab) were retrospectively reviewed. The rate of secondary malignancies was minimal and no therapy-related myelodysplastic syndrome or acute myelogenous leukemia were reported. No deaths from infection were attributable to bendamustine.
