Diagnosis of autoerythrocyte sensitization syndrome in the emergency department.

Autoerythrocyte sensitization syndrome is characterized by sudden and spontaneous painful bruising and swelling occurring in young female patients with psychiatric disorders. This syndrome may present with such severe swelling of involved areas that aspiration or excision may be needed to relieve pressure. The presentation of this condition in the emergency department must be differentiated from more common coagulopathies.

Malignant hemangioendothelioma (angiosarcoma) of the salivary gland: an ultrastructural study.

A case of malignant hemangioendothelioma (angiosarcoma) of the submaxillary salivary gland is reported and its microscopic and ultrastructural features are described and compared to previous reports of angiosarcoma arising in other locations. These tumors may often contain areas of solid sheets of cells without vascular characteristics and may be confused with poorly differentiated carcinoma or other sarcomas. The ultrastructural features of angiosarcoma are compared to other poorly differentiated tumors.
