Dermatofibroma, Aneurysmal Type (Aneurysmal Benign Fibrous Histiocytoma) pathology dermpath

A complete organized library of all my videos, digital slides, pics, & sample pathology reports is available here: kikoxp.com/pos... (dermpath) & kikoxp.com/pos... (bone/soft tissue sarcoma pathology).
Dermatofibromas may show abundant hemorrhage and hemosiderin deposition. These aneurysmal dermatofibromas are often large and deep, which may cause both the dermatologist and the pathologist to be overly worried. This video explains more.
Topics covered:
CD34 staining pattern in DF: 12:42
Increased S100+ dendritic cells in DF: 15:54

Important note: ANEURYSMAL dermatofibroma (aka benign fibrous histiocytoma) is totally UNrelated to ANGIOMATOID fibrous histiocytoma, which is a rare soft tissue tumor of intermediate malignant potential that arises in children. See my video for more info: kikoxp.com/pos...

Nice case thanks for sharing. Perhaps in the future you could do a follow up video with a few more cases of Aneurysmal Dermatofibroma to show the range of features?
