Plexiform fibrohistiocytic tumour is a low‐grade malignant mesenchymal neoplasm of myofibroblastic origin with the capacity for biphasic differentiation toward a fibroblastic or histiocyte‐like morphology. We report a case of this rare tumour presenting as a tender subcutaneous nodule on the scalp of a 58‐year‐old man. Histopathological examination revealed multinodular biphasic proliferation of fibroblast‐like and histiocyte‐like cells with a few osteoclast‐like giant cells. This case is notable for the rare myxoid changes, which may reflect a different behaviour of this tumour when occurring in older people.
