Precursor B‐cell lymphoblastic lymphoma (B‐LBL) is a rare neoplasm composed of immature lymphocytes that demonstrate lymphoblastic morphology and express precursor and B‐cell marker. It usually affects people of younger age group and causes multiple nodules on the head and neck area. The neoplasm is rare in old age. We report a case of B‐LBL occurring in a 65‐year‐old man. He presented with multiple skin nodules on the scalp, the neck and the arm for 2 months. Histopathologic examination demonstrated diffuse dermal and subcutaneous monotonous infiltrates of medium‐sized lymphoid cells with starry‐sky pattern. Immunohistochemical study showed that the lymphoid cells of infiltrate showed precursor B‐cell type. The patient has received combination chemotherapy three times and is being followed‐up at the outpatient clinic.
