From a child:
|
Composite scan view of this symmetrical lesion. Arrows point to peripheral lymphocyte aggregates. |
|
Low power view of the top of this dome shaped lesion. |
|
High power view of above. The pink blobs in the junctional area are Kamino bodies. |
|
High power view of reticular dermis. Arrow points to a poorly-defined fascicle composed of spindle cells. Lymphocytes are found diffusely in the dermis. |
