Abstract
A 31-year-old man with posterior neck mass visited a hospital. The mass recurred four times on the same location during the past 6 years. Needle biopsy diagnosis was suspicious for benign stromal tumor. Tumor excision was performed 3 months after the biopsy. The tumor size was 8.3 × 4.5 cm and was located at subcutaneous tissue. Histologically, main tumor cells showed comma-shaped nuclei, which are same as neurofibroma. Immunohistochemically, tumor cells were positive for vimentin, CD34, but were negative for S-100. Fluorescence in situ hybridization analysis disclosed a split signal of PDGFB gene. Reverse transcriptase-polymerase chain reaction clarified COL1A1 exon 47/PDGFB exon 2 chimeric gene. Final diagnosis was dermatofibrosarcoma protuberans (DFSP) with neurofibromatous change. DFSP with neurofibromatous change is rare and could be misdiagnosed as benign tumor, especially in a biopsy specimen. Molecular diagnosis is a promising aid in a challenging case and in biopsy specimens.

Abstract
PURPOSE Dermatofibrosarcoma protuberans (DFSP) carries a translocation resulting in the collagen type I alpha 1 (COL1A1)-platelet-derived growth factor beta (PDGFB) fusion gene, which is responsible for PDGFB activation. The purpose of this study is to evaluate the clinicopathological, genetic, and therapeutic features of DFSP in Korean patients. MATERIALS AND METHODS Clinicopathological features of 37 patients with DFSP were reviewed. Multiplex reverse transcriptase-polymerase chain reaction (PCR) was carried out in 16 patients using formalin-fixed, paraffin-embedded tissues and specific primers for COL1A1 and PDGFB. RESULTS The mean age of 37 patients was 37.4 years old. The most common tumor location was the trunk. All patients were treated primarily with surgery: 34 (91.7%) cases with Mohs micrographic surgery (MMS) and 3 (8.3%) cases with wide local excision. The median follow-up time was 33.7 months. Two patients, one in each treatment group, demonstrated local recurrence during the follow-up period. The COL1A1-PDGFB fusion gene was expressed in 14 (87.5%) cases, demonstrated by reverse transcriptase PCR analysis. No association was found among the different COL1A1-PDGFB fusion transcripts, the various histological subtypes and clinical features. CONCLUSION Our results support the effectiveness of MMS in treating DFSP. The COL1A1-PDGFB fusion transcript was observed in 87.5% of patients. Therefore, COL1A1-PDGFB is a useful and accurate tool in diagnosing DFSP in Koreans.

Abstract
Approximately one third of soft tissue tumors are characterized by chromosomal aberrations, in particular, translocations and amplifications, which appear to be highly specific. The identification of fusion transcripts not only supports the diagnosis, but provides the basis for the development of novel therapeutic strategies aimed at blocking the aberrant activity of chimeric proteins. Molecular biology, and in particular, cytogenetic and qualitative and quantitative polymerase chain reaction technologies, allow with high efficiency and specificity, the determination of specific fusion transcripts resulting from chromosomal translocations, as well as the analysis of gene amplifications. In this review, various molecular techniques that allow the identification of translocations and consequent fusion transcripts generated are discussed in the broad spectrum of soft tissue tumors.

miR-205 down-regulation promotes proliferation of dermatofibrosarcoma protuberans tumor cells by regulating LRP-1 and ERK phosphorylation. Arch Dermatol Res 2014; 306:367-74.

Abstract
Dermatofibrosarcoma protuberans (DFSP) is an intermediate malignancy of the skin. Although COL1A1/PDGFB fusion gene was identified in the tumor cells recently, not all of the cases were positive for the fusion gene, and further researches are still needed to clarify the pathogenesis of DFSP. In this study, we investigated the role of microRNAs in the tumor. microRNA PCR array showed several microRNAs increased or decreased in DFSP in vivo compared with dermatofibroma (DF) and normal skin. Among them, the expression of miR-205 was down-regulated in DFSP compared with DF and normal skin. In situ hybridization showed that miR-205 expression was evident in dermal fibroblasts of normal skin although hardly detected in tumor cells of DF or DFSP. miR-205 inhibitor increased cell proliferation and the luciferase activity of 3'UTR of low-density lipoprotein receptor-related protein-1 (LRP-1) in cultured normal dermal fibroblasts. Immunohistochemistry showed the expression of LRP-1 was increased in DFSP tissue. Knockdown of LRP-1 suppressed cell growth and down-regulated extracellular signal-regulated kinase (ERK) phosphorylation without affecting MEK phosphorylation in cultured DFSP cells. Taken together, LRP-1 overexpression caused by the miR-205 down-regulation may play a role in the abnormal proliferation of DFSP cells via directly regulating ERK phosphorylation.
