Abstract:
Epithelioid hemangioendotheliomas (EHEs) are known to have a variable malignant potential. EHEs are rarely seen in the hand and there is no consensus about their management. The options include excision, excision followed by adjuvant radiotherapy and amputation. In this paper, we report a case of EHE of a finger that was treated by excision. Although the tumor had ill-defined borders and there was histological evidence of tumor extension to all resection margins, no local recurrence or metastasis were noted during the 3 years of followup. The literature is reviewed and an argument is made that EHEs of the hand may have a more benign behavior compared with EHEs of the lower limbs and viscera.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

The papillary layer is made of loose, areolar connective tissue, which means the collagen...
