Alpha 1-antitrypsin and lysozyme in fibrous papules and angiofibromas.
The large stellate and polygonal cells observed in eleven fibrous papules and two angiofibromas were examined immunohistochemically for alpha 1-antitrypsin and lysozyme. The positive findings suggest that these cells are related to histiocytes rather than nevomelanocytes.
