Abstract:
Dermatofibrosarcoma protuberans is a rare mesenchymal tumor; it is locally aggressive and presents high rates of local recurrence. It may present as a nodular or plaque vegetating lesion. It mainly affects the trunk and proximal limbs, being rare in the distal extremities. Biopsy and immunohistochemistry help confirm the diagnosis. The authors report a case of dermatofibrosarcoma protuberans with plantar region involvement, a rare presentation. To the best of the authors' knowledge, only 11 cases of involvement of the feet were described in the international literature.

01:11Papillary 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.
