Purpose: Dermatofibroma is a lesion several millimeters to several centimeters in size, arising from dermis or subcutaneous tissue, mostly at extremities of a middle aged female. It is a benign fibrous tumor that to our knowledge metastasis have not been reported and may recur only locally. Here we report a rare case of 36-year-old female with dermatofibroma arising from back and metastasized to both lungs. Methods: We performed an en-block elliptical mass excision for skin lesion and metastatectomy for multiple nodules of both lungs. Results: Histologically, the tumors of both lungs and skin lesion showed dilated cystic airspaces which were lined by respiratory epithelium with underlying layers of tumor cells. The tumor cells were composed of plump to spindled fibrohistiocytic cells arranged in storiform growth pattern. There were no cellular pleomorphism, atypical mitosis, and necrosis. These are the specific features of a dermatofibroma and we could examined the histologic findings of skin and lungs identical. Thus, this indicates that dermatofibroma of back was metastasized to both lungs. Conclusion: We report this case to notice that dermatofibroma is a benign tumor but it rarely metastasizes.

Purpose: Dermatofibroma is a common benign dermal tumor characterized by a proliferation of fibroblast-like spindle cells. It is commonly localized on the skin of extremities and presents as a slow growing solitary nodule. To our knowledge, the occurrence of dermatofibroma in the oral cavity is rare. Herein, we report a rare case of dermatofibroma on the lower lip. Methods: A 60-year-old woman presented with a slow growing mass that measured $1{\times}0.8cm$ in diameter on the lower lip. The mass was surgically excised with clear margins. Results: Histologically, the mass was characterized by a nodular tumor composed of collagen bundles, fibroblasts, and histiocytes, which were findings consistent with dermatofibroma. The postoperative course was uneventful without any complications. Conclusion: When evaluating nodular tumors of the oral area, dermatofibroma should be considered in the differential diagnosis.

Dermatofibromas most commonly occur on limbs and rarely occur on the face. Dermatofibroma occurring on the face is associated with unusual clinicopathologic features and a more aggressive clinical course in comparison to typical cases. Additionally, the most common subtype found in previous studies was benign fibrous histiocytoma, with the keloid type being very rare (about 1% of reported cases). The aim of this study was to present our experience with a keloidal dermatofibroma of the face, which is usually missed clinically, and to discuss the treatment of a keloidal dermatofibroma in this location.

The incidence of chest wall tumor is rare than those of other portions of the body. The chest wall tumors need special attention about their diagnosis and management than other tumors. From March, 1985 to September, 1994, 33 patients with chest wall tumor underwent surgical treatment, and those were consisted of 28 benign tumors and 5 malignant tumors arising from soft tissue, rib and sternum.Benign tumors were included 11 lipoma, 4 cysticercosis, 2 chondroma and 1 each of fibroma, dermatofibroma, osteochondroma, fibrous dysplasia and hemangioma,and 6 other cases. Malignant chest wall tumors were included 2 metastatic carcinoma,1 each of giant cell tumor, chondrosarcoma and epithelioid sarcoma.Sex ratio of male to female was 1.5:1, and the range of age was 16 to 72 years,and the mean age was about 40 years. Clinical manifestations of chest wall tumor were palpable mass[55% , pain[21% ,tender mass[9% , growing mass[9% and asymptomatic[9% .The all cases were treated surgically, the results were as follows:Local excision 16 cases, wide resection 12 cases, wide resection with chemotherapy 3 cases, each one case of wide resection with radiotherapy and wide resection with chest wall reconstruction.

Objectives：DFSP(Dermatofibrosarcoma protuberans) is an uncommon, slowly growing, locally invasive malignant tumor that usually presents as a painless, often long-standing mass arising in the dermis of skin. It occurs most frequently on the trunk and proximal parts of the limbs, less commonly in the head and neck region and has a frequent tendency to recur after surgical excision. Clinically, the initial appearance of the tumor similar to that of benign tumor such as keloid and dermatofibroma. Therefore, accurate clinical diagnosis and adequate surgical excision are important. Materials and Methods：We experienced 6 patients of DFSP in head and neck during the recent 6 years, 5 male and 1 female patients. The age of the patients ranged from 31 to 66. As reconstructive methods, the authors used cervicofacial flap, trapezius musculocutaneous flap, TRAM flap, anterolateral thigh free flap and skin graft. Results：The patients were followed up after operation from 24 to 79 months and all remained free of disease except one case, who occurred at forehead area. Conclusion：We present the experience of 6 cases of DFSP occurred in head and neck. We obtained satisfactory results with appropriate diagnosis and treatment which wide excision with surgical margins 3-5cm. We also present an operative plan of this locally aggressive and highly recurrent tumor.
