We report on five cases of skin metastasis according to the breast cancer (BC) subtype. Two cases of HER2 positive BC showed only skin metastasis after immediate postoperative period and rapid clinical response to targeted therapy. Another two cases of triple negative BC showed thyroid and lung metastasis in addition to skin metastasis, and their response of cytotoxic chemotherapy was not definite. The other hormone positive BC showed skin metastasis only, with a longer, slower, less progressive pattern than other subtypes. Most cases of skin metastasis were detected at terminal stage of malignancy and were considered to have a limited survival period. However, some BC patients can survive longer if the targeted agents are effective. Therefore, physicians should provide detailed follow up of BC after curative treatment and understand the metastatic pattern of BC according to the subtype.

Scleroderma is a chronic disease of unknown etiology, it is the sclerosis of the skin characterized by the appearance of circumscribed or diffuse, hard, smooth and ivory-colored areas that are immobile and give the appearance of hidebound skin. Progressed scleroderma can lead to develop various tumors by affecting organs. It is rarely reported that the tumor itself or systemic chemotherapy could be one of the causes of scleroderma. Up to now, the pathogenesis about scleroderma occurring from cancer itself or anticancer drugs are uncertain.

Drug-induced anaphylaxis is a big pitfall in patients receiving antineoplastic chemotherapy. We report a case of lung cancer patient who experienced two near-fatal anaphylactic reactions that resulted from paclitaxel and multivitamin, seperately. Recurrent severe reactions to different agents led to further investigation to which material the patient was hypersensitive. The skin prick test revealed sensitization to cremophor, which is a commonly used emulsifying agent. This case emphasizes the importance of correctly identifying the culprit drug of anaphylaxis to avoid potentially fatal reaction.

Depth of prostate volume from the skin can vary due to intra-fractional and inter-fractional movements, which may result in dose reduction to the target volume. Therefore we evaluated the feasibility of automated depth determination-based adaptive proton therapy to minimize the effect of inter-fractional movements of the prostate. Based on the center of mass method, using three fiducial gold markers in the prostate target volume, we determined the differences between the planning and treatment stages in prostate target location. Thirty-eight images from 10 patients were used to assess the automated depth determination method, which was also compared with manually determined depth values. The mean differences in prostate target location for the left to right (LR) and superior to inferior (SI) directions were 0.9 mm and 2.3 mm, respectively, while the maximum discrepancies in location in individual patients were 3.3 mm and 7.2 mm, respectively. In the bilateral beam configuration, the difference in the LR direction represents the target depth changes from 0.7 mm to 3.3 mm in this study. We found that 42.1%, 26.3% and 2.6% of thirty-eight inspections showed greater than 1 mm, 2 mm and 3 mm depth differences, respectively, between the planning and treatment stages. Adaptive planning based on automated depth determination may be a solution for inter-fractional movements of the prostate in proton therapy since small depth changes of the target can significantly reduce target dose during proton treatment of prostate cancer patients.

Blue rubber bleb nevus syndrome is a rare disorder that is characterized by multiple recurrent vascular malformations, such as hemangioma, and these primarily involve the skin and the gastrointestinal tract. It may also involve the brain, liver, lungs, and skeletal muscles. A 14-year-old female visited our hospital with a chief complaint of dizziness; upon examination, we found multiple recurrent hemangiomas on the skin and gastrointestinal tract. We were able to diagnose her as suffering from blue rubber bleb nevus syndrome and we treated her with methylprednisolone (2 mg/kg/day for 1 month and 1 mg/kg/day for additional 3 months). We report on this case along with a review of the literature.

BACKGROUND: Oral of topical psoralen photochemotherapy is the most popular arid efficacious treatment, available for repigmentation of vitiliginous patches. However this therapy is often used for prolonged periods and various types of pigmentary changes can be observed and sometimes, may be carcinogenic. The safety of PUVA therapy has been an issue of debate. OBJECTIVE: The purpose of the study was to describe in more detail the complications of PUVA treatment and to investigate a possible relation with multiple factors. PATIENTS AND METHOD: We studied 137 vitiligo patients who received PUVA therapy(using oral 8-MOP) for more than six months in our department between March 1990 and June 1996. RESULT: The results are summarized as follows 1. Among 137 cases of vitiligo, the numbers of male and female patients were 40(29.2%) and 97(70.8%) respectively. The mean age at the start of PUVA was 39 years and the mean duration of treatment was 31 months. There were no patients with skin type I and II. Forty cases had skin type III, 68 skin type IV, 29 skin type V. 2. Acute side effects were nausea(35.8%), pruritus(32:8% ), erythema(30.7%), headache(21.2 %), dizziness(18.8%), burning sensation(16.8%), fatigue(8.8%) and the Koebner phenomenon(1.5 %). These are all reversible and disappear on discontinuation of treatment. 3. PUVA-induced pigmentary changes were PUVA lentigines(39 cases;26.3%), hypopigmented confetti macules(36 cased;26.3%), mottling(31 cases,22.6%), nail pigmentation(8 cases,5.8%) and PUVA keratosis(7cases;5.1%) 4. The mean cumulative UVA dose was 1833J/cm and the mean number of treatments was 171. In the high-dose group and the patients who had the most number of treatments, we observed an increased number of patients with PUVA lentigiens and mottling. However, no relationship was observed between the development of PUVA-induced pigmentary changes and sex or age at the start, of PUVA or in relation to skin type. 5. We did not see any patients with melanoma, nonmelanoma skin cancer or systemic cancer. CONCLUSION: Long term exposure to PUVA significantly increases chronic clinical side effects of PUVA. Therefore carefuI clinical follow-up of patients who receive long term PUVA therapy in necessary. This risk shoud be considered in selection of treatment.

A 3-year-old boy presented with bluish patch and scattered blue spots on the left side of his face. After several sessions of laser treatment, the azury patch in the periorbital area became even darker. Histopathology showed many bipolar, pigment-laden dendritic cells scattered in the papillary and upper reticular dermis. Immunohistochemically, these cells were positive for S100, SOX-10, melan-A, P16, and HMB-45. The positive rate of Ki-67 was less than 5%. Finally, the lesion was diagnosed with nevus of Ota concurrent with common blue nevus. Therefore, for cases of the nevus of Ota with poor response to laser treatment, the possible coexisting diseases should be suspected.
