Lower Gastrointestinal Bleeding Because of Kasabach-Merritt Syndrome Showing an Impressive Response to Sirolimus.

Kasabach-Merritt syndrome is a rare but life-threatening disease in which a rapidly growing vascular tumor induces localized intravascular coagulation, causing thrombocytopenia, microangiopathic hemolytic anemia, and consumption coagulopathy. It presents mainly in infants and young children. We present an adult with recurrent and severe lower gastrointestinal bleeding due to Kasabach-Merritt syndrome, treated successfully with sirolimus after multiple other failed interventions.

Epigenetic therapy of lymphoma using histone deacetylase inhibitors.

In this study, we reviewed epigenetic therapy of lymphomas using histone deacetylase inhibitors (HDACi), a promising new class of antineoplastic agents. Epigenetic therapy, a new therapeutic concept, consists of the use of HDACi and or DNA methyltransferase inhibitors (DNMTi). We conducted a comprehensive review of the literature for antitumour activity of HDACi and its mechanism of action.

Acquired acute myelogenous leukemia after therapy for acute promyelocytic leukemia with t(15;17): a case report and review of the literature.

Therapy-related myelodysplastic syndrome (t-MDS) and therapy-related acute myelogenous leukemia (t-AML) in patients with acute promyelocytic leukemia (APL) are rare events. The cumulative exposure to chemotherapy with alkylating agents and topoisomerase II inhibitors is associated with t-AML that may develop any time after the completion of the treatment. We report the case of an acquired AML who previously received therapy for APL, after two years of being diagnosed.

Aleukemic leukemia cutis preceding acute monocytic leukemia: a case report.

Aleukemic leukemia cutis is an extremely rare clinical presentation in patients who eventually develop acute leukemia, usually of monocytic lineage. This condition is associated with a very poor prognosis and is often difficult to diagnose. We report a case of a 33 years old female with leukemia cutis preceding the onset of acute monocytic leukemia by four months.
