RESUMO
Angiosarcoma is a rare tumour, particularly angiosarcoma in the colon. We report such a case, and demonstrate the need to use other methods to supplement the ordinary morphological examination of the tumour in order to verify the correct diagnosis. This is important, in order to plan the correct treatment and follow-up of the patient.

A case of mastocytosis of the bone associated with urticaria pigmentosa was first suspected of being a generalized metastatic malignancy, for the radiographic manifestations were not connected by us with the patient's skin disease. The histologic diagnosis of systemic mastocytosis was also missed primarily, because mast cells are not visualized in the conventional hematoxylin and eosin staining of the histologic sections. Special stainings revealed mastocytosis. Irregular remodeling of the bone was also seen, which was consistent with the radiographically irregular bone structure.
