Purpose: Adjuvant treatment for craniopharyngioma after surgery is controversial. Adjuvant external beam radiation therapy (EBRT) can increase the risk of long-term sequelae. Stereotactic radiosurgery (SRS) is used to reduce treatment-related toxicity.In this study, we compared the treatment outcomes and toxicities of adjuvant therapies for craniopharyngioma. Materials and Methods: We analyzed patients who underwent craniopharyngioma tumor removal between 2000 and 2017. Of the 153 patients, 27 and 20 received adjuvant fractionated EBRT and SRS, respectively. We compared the local control (LC), progression-free survival (PFS), and overall survival between groups that received adjuvant fractionated EBRT, SRS, and surveillance. Results: The median follow-up period was 77.7 months. For SRS and surveillance, the 10-year LC was 57.2% and 57.4%, respectively. No local progression was observed after adjuvant fractionated EBRT. One patient in the adjuvant fractionated EBRT group died owing to glioma 94 months after receiving radiotherapy (10-year PFS: 80%). The 10-year PFS was 43.6% and 50.7% in the SRS and surveillance groups, respectively. The treatment outcomes significantly differed according to adjuvant treatment in nongross total resection (GTR) patients. Additional treatment-related toxicity was comparable in the adjuvant fractionated EBRT and other groups. Conclusion Adjuvant fractionated EBRT could be effective in controlling local failure, especially in patients with non-GTR, while maintaining acceptable treatment-related toxicity.

Background and Objectives: A comprehensive survey of congenital heart disease (CHD) prevalence has not yet been conducted in South Korea. This study aimed to investigate the prevalence of CHDs in Korean children and lay the foundation for national CHD epidemiology. Methods: Target patients were infantile crucial CHDs, which include critical CHDs (requiring urgent procedures after birth with common hypoxemic defects) and diverse categorical defects excluding simple shunt defects. Data were obtained from the National Health Insurance Service over a 5-year period (2014–2018). Birth prevalence (new cases per 1,000 live births) of CHDs in Korea was analyzed and compared with that of other countries. Results: The birth prevalences of right heart obstructive defects (pulmonary valve stenosis and pulmonary atresia), conus anomalies (tetralogy of Fallot and double outlet right ventricle), and total anomalous pulmonary venous return showed significant increases in the East Asian group (P<0.001), whereas those of left heart obstructive defects (coarctation of aorta, aortic stenosis, and hypoplastic left heart syndrome), truncus anomalies (D-transposition of great artery and persistent truncus arteriosus), atrioventricular septal defect, and hypoplastic right heart syndrome were significantly decreased in the East Asian group (P<0.001). Conclusions The overall birth prevalence of crucial CHDs in Korea was similar to that of critical CHDs in previous studies from other countries. Some subtypes of right heart obstructive defects, left heart obstructive defects, and conotruncal anomalies showed significant differences between East Asian and Western populations. This study contributes to a foundation for national CHD epidemiology in Korean children.

The incidence of anaplastic large cell lymphoma is 0.25 cases per 100,000 people. It usually causes lymphadenopathy and B symptoms; however, diverse cutaneous manifestations can also be observed. We report a rare case of anaplastic large cell lymphoma of the scalp, which presented similarly to a ruptured epidermal cyst. A 77-year-old woman visited the outpatient clinic complaining of scalp masses that had appeared 2 months before. One week before her visit, she had undergone incision and drainage at a local clinic but showed no improvement. Before surgery, facial magnetic resonance imaging revealed two suspicious ruptured cystic masses. Surgical excision was performed with a 1-cm free margin from the soft mass. Histopathology confirmed anaplastic lymphoma kinase-negative anaplastic large cell lymphoma. After wide excision and skin grafting for wound reconstruction, followed by consultation with a hemato-oncologist and radiation oncologist, chemotherapy was planned to prevent recurrence. Differentiating anaplastic lymphoma kinase-negative anaplastic large cell lymphoma of the scalp from a ruptured epidermal cyst-like mass proved challenging. We recommend considering the possibility of anaplastic large cell lymphoma if an epidermal cyst-like mass does not respond to antibiotics or conventional dressing, as illustrated by our rare case.
