Abstract

The immunohistochemical detection of different isoforms of actin provides useful data in the histopathological diagnosis of human tumours. The marked resistance of this protein to fixation and embedding procedures makes it a practical alternative to the ultrastructural search of microfilaments in routine tissue sections. Staining with monoclonal antibodies against alpha smooth muscle actin is helpful in the diagnosis of benign and malignant smooth muscle tumours and allows the differentiation of various types of spindle cell sarcomas. These antibodies are also useful in tracing the myoepithelial cells in normal and various pathological conditions of the breast and salivary glands. Skeletal muscle actin is a reliable marker in the diagnosis of rhabdomyosarcomas. Its use should be combined and complemented with other markers (i.e. desmin; foetal, slow and fast myosins; myoglobin) to monitor the degree of rhabdomyoblastic differentiation of the neoplastic cells in single cases, a parameter of potential prognostic value.
