2022年4月11日 · Aneurysmal and hemosiderotic variants are both characterized by numerous multinucleate cells and prominent hemosiderin deposition due to red blood cell extravasation; distinction between these two is the pseudovascular spaces with blood in aneurysmal type (Histopathology 1995;26:323)

2017年7月16日 · Hemosiderotic or aneurysmal dermatofibroma usually manifests with a multi-component or atypical dermoscopic pattern with central bluish/reddish homogenous areas in combination with white structures, peripheral delicate pigment network, and vascular structures.

2023年10月28日 · Aneurysmal dermatofibroma (ADF) and hemosiderotic dermatofibroma (HDF) are rare variants of dermatofibroma (DF) characterized by distinct histologic features. While HDF is traditionally considered a precursor to ADF, supporting evidence is limited, and the etiology remains unclear.

2024年11月20日 · Aneurysmal dermatofibroma. Aneurysmal dermatofibroma contains blood-filled spaces and deposits of hemosiderin, a substance that forms when blood breaks down. These features can make the lesion look like a vascular tumour, which is a …

Aneurysmal dermatofibroma is an uncommon, benign variant of dermatofibroma due to the slow extravasation of blood. Clinically, it is difficult to differentiate from other vascular occurring lesions like verrucous hemangioma and
