Background: The growth factors derived from platelets contained in platelet-rich plasma comprise a series of molecules that favor the production of collagen with the proliferation of fibroblasts and new blood vessels. These substances exert their effect on the cells, acting in all the stages of cicatrization, especially in hemostasis and early fibroplasia.
Methods: Thirty-five patients (70 feet) were selected, operated on both sides for ingrown hallux nails, and subjected to two different experimental conditions in a crossover clinical trial with positive control of treatment. Two main variables were analyzed: on one side, the bleeding, according to three preestablished categories, and on the other, the mean time of cicatrization in days.
Results: Significant differences (P < .001) were found between the two groups for bleeding. We observed that cicatrization time did not differ significantly between the two treatments.
Conclusion: The use of platelet gel for the treatment of onychocryptosis by single nonincisional matricectomy can guarantee good hemostasis, with a significant reduction in bleeding, but does not produce a clinically significant reduction in cicatrization time.

Myxoinflammatory fibroblastic sarcoma of the soft tissues is a rare low-grade tumor of uncertain origin that most often occurs on the extremities of adults. The tumor predominantly involves the subcutaneous tissues of the hands and feet. Despite being a rare neoplasm, owing to its varied histologic appearance, myxoinflammatory fibroblastic sarcoma should be differentiated from various benign and malignant soft-tissue lesions. Myxoinflammatory fibroblastic sarcoma has been well described in pathology journals but not in the surgical literature. We report a case of myxoinflammatory fibroblastic sarcoma in a 19-year-old man with a plantar ulcer lesion in his left foot. To our knowledge, this is the first reported case in the literature involving the epidermis. (J Am Podiatr Med Assoc 100(6): 497–501, 2010)
