A Rare Case of Rapid Lymphadenopathy Progression in Hodgkin's Lymphoma: A Case Report.

Hodgkin's lymphoma is a B-cell neoplasm that typically manifests with gradual lymphadenopathy progression over weeks to months. However, we present an exceptional case of Hodgkin's lymphoma marked by an unusually rapid development of lymphadenopathy within an hour. A 30-year-old male presented with a left neck swelling that occurred within an hour and then remained stable in size for three days, prompting an investigation revealing widespread lymphadenopathy consistent with Hodgkin's lymphoma. This case outlines the importance of recognizing and investigating unusual presentations of Hodgkin's lymphoma promptly, emphasizing the necessity for expedited diagnosis and intervention.

Refractory pancytopenia upon initiation of asciminib in tyrosine kinase inhibitor-resistant chronic myeloid leukemia.

Asciminib, a "Specifically Targeting the ABL Myristoyl Pocket" inhibitor, is a new drug in the treatment of tyrosine kinase inhibitor (TKI)-resistant chronic myeloid leukemia (CML). Hemocytopenias associated with asciminib are common adverse events documented by clinical trials. We report a case of precipitous-onset pancytopenia with the initiation of asciminib treatment in a patient with TKI-resistant CML. This case had a confounding array of laboratory findings that evidenced a drug-induced hemophagocytic component. We hope that our case stimulates further reporting of similar cases to enhance the understanding of the pathophysiology underlying asciminib-induced hemocytopenias.

The Tale of a Rubbery White Clot: Poorly Differentiated Spindle Cell Sarcoma Presenting As Superior Vena Cava Syndrome.

Sarcoma is an uncommon neoplasm of mesenchymal origin (1). The presentation is usually vague. It may present as a mass in the thigh or retroperitoneum, with resultant pain or paresthesia of the affected area. The diagnosis is very challenging due to its indistinct presentation. The prognosis remains poor due to delays in diagnosis and few available therapeutic options. We herein report the first case of superior vena cava (SVC) syndrome caused by spindle cell sarcoma.

Treatment of acute myelogenous leukemia with outpatient azacitidine.

BACKGROUND: Patients older than 55 years of age with acute myelogenous leukemia (AML) are less likely to achieve complete remission and more likely to experience toxicity with conventional induction chemotherapy than younger patients. Azacitidine administered in the outpatient setting is well tolerated and can induce complete hematological remission in patients with myelodysplastic syndromes (MDS). At higher doses, azacitidine has activity in AML. METHODS: Twenty patients were retrospectively identified who had been treated with azacitidine with bone marrow blast counts between 21 and 38%. Patients with blast counts up to 29% were initially treated as MDS, but by WHO now meet criteria for AML. Patients with blast counts over 29% were treated with azacitidine after being deemed poor candidates for induction chemotherapy. Azacitidine 75 mg/m2/day was administered subcutaneously for 7 days every 4 weeks, which was defined as 1 cycle. RESULTS: The overall response rate was 60% (12/20): complete response (CR; n = 4; 20%); partial response (PR; n = 5; 25%); hematologic improvement (HI; n = 3; 15%). The median survival of responders was 15+ months compared with 2.5 months for nonresponders (P = .009). During therapy, responders had an Eastern Cooperative Oncology Group (ECOG) performance status of 1 or 0. The most common toxic event was infection (n = 8). Four patients were hospitalized during the first cycle of treatment. CONCLUSIONS: Azacitidine administered in the outpatient setting can induce remission in AML. The therapy is well tolerated and might be an alternative for patients unlikely to tolerate standard induction chemotherapy.
