RESUMEN
Malignant fibrosis histiocytoma (MFH) is one of the most common soft tissue sarcomas of adult life. The most common sites of origin are the proximal extremities, particularly the thigh and buttock. The tumors are multilobular fleshy masses, often apparently circumscribed on gross examination. We report a case of a MFH of the head in a 57-year-old woman. Our case is clinically unusual in that the tumor rapidly grew up to 15 cm in a very short time.

Nodular fasciitis represents reactive myofibroblastic proliferative lesions in the subcutaneous tissue, skeletal muscles, and fascia. Uncommon clinical and pathological variants of nodular fasciitis, such as intravascular, cranial, ossifying, and proliferative fasciitis, have been described. Six cases documenting a dermal location of nodular fasciitis have been reported in the English literature. Some authors have described that the histopathological features of intradermal nodular fasciitis are virtually identical to those of postoperative/posttraumatic spindle cell nodule of the skin. We herein report a 41-year-old Korean woman presenting with a 0.5 cm facial papule in which nodular fasciitis occurred in the dermis.
