The paraneoplastic leukemoid reaction is a rare haematological paraneoplastic syndrome, which is typically seen with solid tumours and squamous cell carcinomas. As an indication of bone marrow infiltration and malignancy involvement, it indicates a poor outcome and a grave prognosis. We report a woman in her 50s, who presented with an ulcer over the right forearm. Biopsy revealed squamous cell carcinoma. The patient underwent radiological investigations, which showed the presence of metastatic squamous cell carcinoma. Incidentally, the patient was found to have leucocytosis, which was attributed to a paraneoplastic leukemoid reaction, after ruling out all other causes of leukemoid reaction. Due to metastatic disease, the patient was planned for palliative radiotherapy and the best supportive care.
