    ABSTRACT: Hemoglobin (Hb) variants may be associated with low oxygen saturation and exacerbated episodes of anemia from common stressors such as viral infections. These attributes frequently cause increased clinical concern and unnecessary and expensive testing if not considered early in the evaluation of the patient. Some clinically significant Hb variants result in a normal Hb electrophoresis result, which can be method-dependent. Herein we describe a patient with low oxygen saturation and a history of hemolytic anemia who was subsequently found to carry a novel, unstable β-globin variant that we have named Hb Allentown [β137(H15)Val→Trp (GTG>TGG) HBB: c.412_413delinsTG, p.Val138Trp] for the place of identification of the variant. Hb Allentown is formed by a rare double nucleotide substitution within the same codon. Additionally, positive identification of rare Hb variants characterized by a single method is discouraged, as the Hb variant was misclassified as Hb S-South End or β6(A3)Glu→Val;β132(H10)Lys→Asn (HBB: c.[20A > T;399A > C]) by the initial laboratory.

    ABSTRACT: Cutaneous Ewing sarcoma is a rare variant that has been poorly characterized and has no standard therapy. We report 2 patients with cutaneous Ewing sarcoma and review 76 other cases reported in the literature for demographics, presentation, treatment, and outcome. Only 2 patients presented with metastatic disease, and only 8 patients developed metastatic disease. Ninety-one percent of all patients are alive despite wide variations in treatment regimens. On the basis of this summary, treatment consisting of local control with surgery and/or radiation and abbreviated chemotherapy is proposed as a treatment option for this less aggressive Ewing sarcoma.
