We have observed CA in gastrointestinal leiomyomas (GILM) and hypothesised that they differ from intracytoplasmic hyaline globules (HG) of GILM.

CA stained intensely with periodic acid Schiff after diastase predigestion (PASD), Alcian blue and ubiquitin, and faintly in peripheral zones for desmin and smooth muscle actin. Ultrastructurally, CA consisted of an electron-dense outer layer and a fibrillar core with scattered particle matter. HG were present in all leiomyomas, but showed variable staining for PASD, negative staining for Alcian blue and ubiquitin, and positive staining for smooth muscle markers.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>CA are a distinctive histological feature of approximately one third of GILM with different composition to HG.
