ABSTRACT
A dog bite is the most common trauma among animal bites, and it has varying severity, from simple skin lacerations to defects in whole tissue layers. Considering the aesthetic and functional importance of the nose, an appropriate reconstruction should be conducted for large and full-thickness tissue defects. Although this is quite common, literature detailing surgical reconstruction is lacking, especially in domestic journals. A 45-year-old male patient visited an outpatient clinic due to nasal trauma caused by a dog bite. The patient’s nose showed whole-layer tissue defects, with necrotic tissues at the periphery. Nasal reconstruction surgery was conducted using a forehead flap and ear cartilage composite graft. Pedicle division was conducted three weeks after primary surgery. The functional and aesthetic outcomes of the surgery were satisfactory. Our experience demonstrates that the forehead flap is a useful option for reconstructing a nose badly injured by a dog bite.
ABSTRACT
Background and Objectives@#Scalp angiosarcoma is a rare but aggressive vascular malignancy. It is often found in the advanced state and tends to cause distant metastasis at an early stage. There is no consensus on a treatment modality, although wide excision followed by adjuvant therapy is currently used. The purpose of this study was to analyze the treatment results and disease progress pattern of scalp angiosarcoma in a single institution.Subjects and Method We enrolled patients who diagnosed with scalp angiosarcoma at Asan Medical Center from March 2011 to September 2019. Disease course and prognostic factors were analyzed by estimating overall survival rate and disease free survival. @*Results@#A total 12 patients were enrolled in this study. The median overall survival was 16.0 months. The 3-year-survival rate was 10.6%, and the median disease free survival was 5.0 months. On the average, it took 11.4 months till death after recurrence. @*Conclusion@#Although wide surgical excision and multiple adjuvant therapies are employed, scalp angiosarcoma showed frequent recurrences and metastasis which led to poor outcomes. Further investigations for scalp angiosarcoma are necessary to improve treatment outcomes.
