Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue sarcoma, with an incidence of about 0.8% to 5% per million people per year, accounting for 1% of soft tissue sarcomas. In its early stage, DFSP is typically found as a violet or pinkish macule or patch, and it can develop into a palpable mass with ulceration or bleeding. The standard treatment for DFSP is wide local excision of the tumor with a 2- to 3-cm negative margin, and radiation therapy or chemotherapy can be conducted with surgical treatment. A 35-year-old man had a palpable mass on the left side of his occipital scalp without color change, ulceration, or bleeding, which typically are present in malignancy. A magnetic resonance imaging (MRI) scan showed a 3-cm homogenous enhanced mass without adhesion between the scalp and the mass. Unexpectedly, a biopsy revealed the round mass to be DFSP. A wide excision and rotation of the scalp flap were performed. The patient recovered without any complications and received adjuvant radiotherapy at a dose of 60 Gray (Gy) for six weeks. There was no recurrence through six months of follow-up. Here we report this unique case of DFSP with atypical presentation.

Renal cell carcinoma (RCC) represents 2% to 3% of human cancers and is aggressive, with metastatic capability. The frequent metastatic sites are lung, bone, and liver. Reports of RCC metastatic to skin, and especially scalp are rare. Here we present an 83-year-old woman who was diagnosed with RCC 19 years prior and had a metastatic scalp lesion. An 83-year-old woman presented with a red-to-purple, protruding lesion at the right parietotemporal area. Twenty-three years ago, a right renal mass was incidentally discovered on ultrasound through a routine medical examination. She underwent right nephrectomy for RCC 4 years later. Five months after nephrectomy, new lung nodules were observed. Fifteen years after nephrectomy, metastatic lesions were found in the pelvic bone. She visited dermatology department for evaluation of the new scalp lesion, a year before she first visited our department. Despite chemotherapy, the mass was gradually enlarged. She consulted the plastic surgery department for management of the metastatic RCC was successfully treated with total excision including a 1-cm safety margin, local flap, and STSG coverage. Complete healing was observed, without evidence of recurrence during a 7-month followup. Metastases to the skin are rare, but must be kept in mind because of its high metastatic ability and poor prognosis.

A scalp mass surgically excised from a 4-year-old Korean boy was identified as a tick through histological observations. In sections of the mass, characteristic features of a tick, including its gross contour, cuticular structures, well developed musculature and salivary glands, and the capitulum, were discovered. In particular, the capitulum is anteriorly protruded, which strongly suggests that the specimen be a hard tick of family Ixodidae. However, the pre-sent histological features were not enough to determine the genus and species of the tick, because information on sectional morphologies of different tick species is unavailable. This is a rare case of tick infestation on the scalp diagnosed in histological sections.

Purpose: Angiosarcoma of the scalp is unusual vascular tumor originating from endothelial cell. Angiosarcoma is an aggressive tumor with high propensity for both local recurrence and distant metastasis. We report 2 cases of angiosarcoma having poor prognosis recently. Methods: Case 1 was a 67 - year - old male patient. He visited the hospital with a $3{\times}5cm$ sized discolored mass in forehead. It began at one month ago from coming to the hospital. Case 2 was a 64 - year - old male patient. He visited for our hospital to remove a $4{\times}5cm$ sized scalp mass. He had a pruritis on scalp from 9 months ago before coming to the hospital. Despite of the conservative treatments, the wound was not healed and advanced necrotic lesion with hemorrhage. Results: Case 1 diagnosed as an angiosarcoma. He underwent a radical operation 5 times. But the tumor expanded multiple area in dura & frontal area of the brain. The patient rejected the treatment any more. And he died one month later. Case 2 diagnosed as an angiosarcoma and metastased to skull in MRI. He got a radical resection including cranium. Three months later, it recurred to ipsilateral Sternocleidomastoideus muscle. He got a additional operation & started radiotherapy. And now he is receiving chemotherapy, but the recurred lesion is expanding. Conclusion: Angiosarcoma is a highly malignant tumor. Especially it arises in vascularized area, it easily metastases. So it is the best to treat angiosarcoma with surgery included wide margins. Despite of the lesion is small, we remember that angiosarcoma is a tumor that consider to metastases.

The survey was carried out with a random sample of adults living in Busan and Gyeongnam. The collected material is used by the SPSS version 12.0. The frequency, percentage, examination were applied for studying. We separated the group of safety, general management, real hair management according to characteristic about scarp and hair problems. There is highly understanding about the hair problem that if someone has really sensitive scalp or who has dandruff or who has thin hair or who has someone has hair losing problem in their family. Usually, the group has highly understanding of hair problem, they consult about their hair and scalp with expert. They have a really good attention about the mass media(TV, Internet, Newspaper, Magazine) for scalp and hair health. They reduce using hair products. They always read hair product brochure first and use it. They don't eat fast food frequently. The survey has shown high levels of article. Now the research showed us that s have a strict connection between self-recognition and scalp treatments. That means someone has understanding hair problem then start treatment first.

Objective : The object of this study is to present the treatment experience of the 6cases of scalp arteriovenous malformations[AVMs] focus on treatment strategy. Methods : Six patients with scalp AVM were treated during past 12years. We analysis the clinical characteristics of the lesions, treatment methods and management outcomes. Results : The lesions were located on temporal in 2patients, parietal in 2patients, frontal and occipital area in each one. Four of six patients had a trauma history on scalp. The presenting symptoms were progressive enlarged pulsating mass with or without bruit. Four of the six lesions had the large fistula in the lesion. Two patients were treated with surgical resection alone, three patients with proximal feeding artery balloon[s] occlusion followed by surgical resection, and one patient with coil embolization through trans-venous route alone. We obtained good results in all patients. Conclusion : Most of scalp AVM can be completely cured by Judicious selection and a combination of treatment modalities, i.e., surgery only, or embolization only, or embolization plus surgical therapy. Although embolization became a primary therapy for this sort of scalp AVM recently, the selection of treatment modality should be chose based on the size, angioarchitecture, and clinical presentations of the lesion.

Adenoid cystic carcinoma(ACC) is the second most common malignant neoplasm in the salivary gland. In spite of ACC shows slowly growing nature, it is sometimes highly detrimental that it readily invades adjacent tissues and metastasize to distant organs at the early stage of disease. Hence, treatment outcome may be misfortunate due to wide regional infiltration, pathognomonic perineural spread and the tendency of hematogenous metastasis. We present a unusal case of ACC of the scalp in which the patient initially presented with bumpy mass of the scalp who had been diagnosed as the primarily developed ACC of the right hard palate that extended to infratemporal fossa, nasal cavity, and paranasal sinuses and had been treated by total excision and post-operative chemotherapy and radiation therapy for 10 years ago. Although this lesion occured at the scalp, which is a frequent site of primary dermatologic ACC, its histomorphology was the same with that of previous tumor. Complete clinical examination showed no recurrence sign at the primary site and suggested the scalp as a sole treatment failure site. Accordingly, it would be reasonable to consider the present case as either a scalp metastasis or a second primary lesion of salivary gland ACC.

A human case of tick bite on the scalp was found at a local hospital on June, 1984. The patient, 63-year old female, was attacked by a tick while working in a farm forest which located in the suburbs of Seoul. The clinical complaint was a (worm) mass on the scalp which she thought as a tumor. On admission the patient complained of facial edema and general malaise. After removal of the mass (tick), small bleeding and discoloration were observed around the biting site. The tick was morphologically examined and identified as Ixodes nipponensis. This is the 4th human case of tick bite reported in the literature of Korea.

Meningothelial hamartoma is a benign tumor composed of ectopic meningothelial elements in the dermis and subcutaneous tissue. It mainly occurs in the scalp; however, the incidence is extremely low. The origin of meningothelial hamartoma has not been elucidated; nevertheless, it has been theorized that it derives from ectopic meningothelial rests displaced during embryologic development. It can be diagnosed histologically as proliferation of connective tissue elements and cells arranged in solid nests, resembling vascular tumors. On immunohistochemistry, it stains positively for epithelial membrane antigen and vimentin. At least 17 cases have been reported, verifying the rarity of the lesion. We present the case of a 16-year-old male patient with a soft scalp mass which was thought to be a lipoma, but turned out to be a meningothelial hamartoma on histology.

Purpose: Epidermal nevi are hamartomas of the skin with multiple clinical variants. Normally, epidermal nevi present at an early age, are found on the head and neck area, and have a female predominance. Only very rarely do epidermal nevi have an adult onset. Most lesions are small and giant Epidermal nevi (> 5 cm at its greatest diameter) are quite rare. Huge verrucous plaque was observed on the scalp of a 70-year-old man. He had been reclusive for a long time, and this problem might have played a crucial role in the development of the giant epidermal nevi. Methods: A punch biopsy and MRI imaging were performed. The huge mass was resected. A local flap and split thickness skin graft was used for reconstruction. Results: The histology examination revealed the characteristic findings of epidermal nevus. Postoperatively, the patient did not suffer from complications or recurrence. Conclusion: A rare case of a huge epidermal nevus on the scalp of an elderly man was treated with a surgical excision. This is the oldest patient reported with an adult onset epidermal nevus in Korea.
