General and Systemic Histopathology, C601&C602
    Slide 19: Acute Erosive Esophagitis  
    Your slide shows almost a complete cross section of the esophagus.  Note there are several areas of mucosal ulceration and some relatively large, thin walled vessels are present in the lamina propria.

    See this slide with the virtual microscope.

    If you simply look at the slide on a white background, you can see the area of erosion quite nicely. Note the areas of healing and repair at the margins of the ulcer. Some acute inflammatory cells are seen in the base of the lesion, and many very dilated vessels are present in this area as well. These large superficial vessels are not part of the healing process, and represent part of another pathologic process in this person. What condition could lead to these dilated vessels? Where would you expect to find others?
