Myeloid leukemia cutis (LC) is the cutaneous involvement by neoplastic leukocytes of the myeloid series. Myeloid LC may occur de novo or concurrently with acute myeloid leukemias, chronic myeloid leukemias, other myeloproliferative disorders or myelodysplastic syndromes. We describe an unusual case of cytophagic S-100 protein immunoreactive leukemia cutis presenting in an 87-year-old woman with...

TECHNOLOGY In this paper, we report a manufacturable InP DHBT technology, suitable for medium scale mixed-signal and monolithic microwave integrated circuits. The MBE grown InP-based DHBTs with an emitter area of 1 × 4 μm exhibited peak cutoff frequencies (fT and fMAX) > 300 GHz, and a breakdown voltage (BVCEo) of ~ 5 V. The InP DHBT layer structures were grown on 3” semiinsulating InP substrat...
