RT Journal Article SR Electronic T1 Leukemoid reaction: a rare paraneoplastic event in a case of advanced penile cancer and its management JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e230826 DO 10.1136/bcr-2019-230826 VO 12 IS 8 A1 Amit Kumar Mishra A1 Ketan Mehra A1 Ramanitharan Manikandan A1 Lalgudi Narayanan Dorairajan YR 2019 UL http://casereports.bmj.com/content/12/8/e230826.abstract AB Leukemoid reaction is a paraneoplastic phenomenon associated predominantly with solid tumours. Malignancies presenting with leukemoid reaction have a grave prognosis. It is defined as persistent neutrophil count greater than 50×103 cells/µL. We report a case of leukemoid reaction in a patient with metastatic penile cancer. A 60-year-old man with partial penectomy status for squamous cell carcinoma of penis on neoadjuvant chemotherapy, presented with left fungating inguinal lymphadenopathy and total leucocyte count 96×103 cells/µL and hypercalcaemia. Leucocytealkaline phosphatase (LAP) score was excessively elevated. The patient underwent left ilioinguinal block dissection along with vastus lateralis flap for defect reconstruction. Postoperatively, the neutrophil counts and serum calcium level normalised. The patient improved clinically and was discharged.
