Dermatofibroma (fibrous histiocytoma) pathology
Aneurysmal dermatofibroma. The clinical presentation of aneurysmal dermatofibroma is a rapidly growing blue-brown nodule. Periods of rapid growth are secondary to haemorrhage into the lesion. These tumours have a high recurrence rate and there is a report of aneurysmal dermatofibroma with regional lymph node involvement.

Aneurysmal Dermatofibroma After Varicose Vein Surgery
Aneurysmatic dermatofibroma represents approximately 1.7% of all types of dermatofibromas [ 1 ]. Like any dermatofibroma, this subtype may appear after local trauma. Its clinical diagnosis can be difficult due to its resemblance to malignant tumors, such as Kaposi sarcoma, angiomatoid malignant fibrous histiocytoma and melanoma [ 2 ].
