Eccrine porocarcinoma is a rare malignant tumor arising from the intraepidermal ductal portion of the eccrine sweat gland. It develops either spontaneously or from a long standing benign eccrine poroma. This entity usually affects older people and is commonly located on the lower extremities, the trunk, and the head. We report a case of eccrine porocarcinoma on the left cheek in an 85-year-old male. In our case, the tumor was treated with wide excision and postoperative adjuvant radiation therapy. The patient recovered well without local recurrence and distant metastasis during the 14-month follow-up period. Wide excision and postoperative adjuvant radiation therapy can be considered as a safe and effective treatment option in treating patients with eccrine porocarcinoma.

C-X-C motif chemokine receptor 4 (CXCR4) plays a key role in various physiological functions, such as immune processes and disease development, and can influence angiogenesis, proliferation, and distant metastasis in tumors. Recently, several radioligands, including peptides, small molecules, and nanoclusters, have been developed to target CXCR4 for diagnostic purposes, thereby providing new diagnostic strategies based on CXCR4. Herein, we focus on the recent research progress of CXCR4-targeting radioligands for tumor diagnosis. We discuss their application in the diagnosis of hematological tumors, such as lymphomas, multiple myelomas, chronic lymphocytic leukemias, and myeloproliferative tumors, as well as nonhematological tumors, including tumors of the esophagus, breast, and central nervous system. Additionally, we explored the theranostic applications of CXCR4-targeting radioligands in tumors. Targeting CXCR4 using nuclear medicine shows promise as a method for tumor diagnosis, and further research is warranted to enhance its clinical applicability.

Purpose: Stereotactic radiosurgery (SRS) has been introduced for small-sized single and oligo-metastases in the brain. The aim of this study is to assess treatment outcome, efficacy, and prognostic variables associated with survival and intracranial recurrence. Materials and Methods: This study retrospectively reviewed 123 targets in 64 patients with non-small cell lung cancer (NSCLC) treated with SRS between January 2006 and December 2012. Treatment responses were evaluated using magnetic resonance imaging. Overall survival (OS) and intracranial progression-free survival (IPFS) were determined. Results: The median follow-up was 13.9 months. The median OS and IPFS were 14.1 and 8.9 months, respectively. Fifty-seven patients died during the follow-up period. The 5-year local control rate was achieved in 85% of 108 evaluated targets. The 1- and 2-year OS rates were 55% and 28%, respectively. On univariate analysis, primary disease control (p < 0.001), the Eastern Cooperative Oncology Group (ECOG) performance status (0-1 vs. 2; p = 0.002), recursive partitioning analysis class (1 vs. 2; p = 0.001), and age (<65 vs. ${\geq}65$ years; p = 0.036) were significant predictive factors for OS. Primary disease control (p = 0.041) and ECOG status (p = 0.017) were the significant prognostic factors for IPFS. Four patients experienced radiation necrosis. Conclusion: SRS is a safe and effective local treatment for brain metastases in patients with NSCLC. Uncontrolled primary lung disease and ECOG status were significant predictors of OS and intracranial failure. SRS might be a tailored treatment option along with careful follow-up of the intracranial and primary lung disease status.

배경: 이 연구는 비소세포암 환자에서 종격동 임파선 전이 여부를 정확히 예측하기 위해서 PET/CT에서 종격동 임파선과 폐종괴의 FDG 섭취비와 폐종괴의 Glut-1 발현 정도를 이용하여 분석 하고자 하였다. 대상 및 방법: PET/CT에서 폐종괴와 종격동 임파선에서 측정할 수 있는 정도의 FDG섭취가 있는 환자를 대상으로 하였다. FDG 섭취비는 종격동 임파선의 섭취를 폐종괴의 섭취로 나누어 구하였다. 폐종괴의 Glut-1 발현은 발현 면적으로 나타내었다. 결과: 폐종괴와 종격동 임파선의 mSUV값은 악성군에서 각각 $7.4{\pm}2.2$와 $4.2{\pm}2.2$, 양성군에서 각각 $7.6{\pm}3.7$와 $2.8{\pm}6.9$였다. FDG의 섭취비는 악성군과 양성군에서 각각 $0.58{\pm}0.23$과 $0.45{\pm}0.20$ (p<0.05)였다. FDG 섭취비와 Glut-1 발현 정도를 결합한 모델 중에서 {p/(1-p)}=ratio+glut+ratio${\times}$glut의 식으로 표시된 모델이 FDG 섭취비만을 이용한 모델 보다 정확히 종격동 임파선의 악성 정도를 예측할 수 있었다. 결론: 염증성 폐질환의 병력이 있는 일부 폐암 환자에서 Glut-1 발현 정도를 고려한 FDG 섭취비를 분석한 모델은 종격동 임파선의 악성 정도를 정확히 진단할 수 있다.

Ovarian cancer is common malignant disease with high mortality in the female. However, lymph node metastasis in the head and neck of ovarian cancer is very rare than in para-aortic, pelvic lymph node. A 49-year-old female patient came to our clinic with a left neck mass. After total thyroidectomy and left selective neck dissection for the cervical neck level II, III, IV, V, VI for ovarian cancer and thyroid cancer, she had already undergone chemotherapy (Paclitaxel+Carboplatin) 18 month ago. CT scan showed only lymph node enlargement in left neck level II. Positron emission tomography-computed tomography (PET-CT) revealed a hypermetabolic lesion in same area but no other hypermetabolic lesion, especially in the pelvic and abdominal cavity. Fine needle aspiration cytology revealed metastatic carcinoma. The serum level of CA-125 was elevated to 43.8U/mL, whereas other tumor markers (CA 19-9, CEA) were in the normal range. She underwent a revision of selective neck lymph node dissection for the cervical neck levels I, II, and III, and on the review of surgical pathology, metastatic carcinoma was suspected. Thus, we performed immunohistochemical staining for the tissue; as a result, it was finally diagnosed as metastatic ovarian cancer (positive for CK7, ER and PR, and negative for CK20). Adjuvant chemotherapy (Paclitaxel+Carboplatin) was planned on the tumor board, and the patient successfully received chemotherapy.

Malignant fibrous histiocytoma(MFH) is a deep-seated pleomorphic sarcoma, which occurs principally as a mass of the extremities, abdominal cavity, or retroperitoneum in adults. However, it only rarely occurs in the chest wall. An 85-year-old man had undeergone excision of a small mass on the right posterior chest wall under local anesthesia 14 months age. However, the lesion did not heal and the mass recurred. He was referred to our hospital after the mass had grown to a size of 10.5$\times$8$\times$4cm with a 3$\times$3cm skin defect. Intraoperative frozen biopsy revealed MFH. An en-bloc wide resection and thin-thickness skin graft from his thigh were performed. Although distant metastasis to the lund developed 14 months later and the patient died 2 months later, there was no local recurrence. Thin-thickness skin graft is a simple method for a wide range skin defect, especially in the old age. He recovered in good condition without any physical disabilities.

배경: 최근 항암화학요법의 발달에도 불구하고 전이성폐암에 대한 예후는 불량하다. 이에비해 전이성폐암에 대한 외과적 요법후 좋은 결과를 보이는 보고가 증가하고 있다. 그래서 전이성 폐암에 대한 치료에 도움이 되고자 본원의 경우를 관찰하였다. 대상 및 방법: 1983년부터 1997년까지 수술적 치료를 했던 17례를 분석하였고 Kaplan-Meier 방법으로 5년생존률을 구하였다. 결과: 평균연령은 42.8세였고 남녀비는 10:7이었다. 수술은 단일폐엽절제술이 8례, 전폐적출술이 3례, 부분절제술이 1례, 쌍폐엽절제술이 1례, 폐엽절제술 및 부분절제가 3례있었다. 술후 5명이 사망하였고 이중 재발로 인한 것은 3례였다. 나머지 12례의 환자들중 3명은 재발하여 현재 외래추적관찰중이며 9명은 재발없이 건강한 상태로 외래추적 관찰중에 있다. 술후 평균 생존기간은 40.5개월이었다. Kaplan-Meier 방법으로 구한 5년생존율은 60.4%였다. 결론: 앞으로 더많은 경험이 필요하지만 전이성폐암에 대해서 더 적극적인 수술적치료를 하는 것이 필요하다고 생각한다.

Objectives: Leiomyosarcoma is a malignant neoplasm that affects smooth muscle tissue and it is very rare in the field of oral and maxillofcial surgery. The purpose of this study was to obtain information on diagnosis of and treatment methods for leiomyosarcoma by retrospectively reviewing of the cases. Patients and Methods: The study included nine patients who were diagnosed with leiomyosarcoma in the Department of Oral and Maxillofacial Surgery at Seoul National University Dental Hospital. The subjects were analyzed with respect to sex, age, clinical features, primary site of disease, treatment method, recurrence, and metastasis. Results: Particular clinical features included pain, edema, mouth-opening limitations, dysesthesia, and enlarged lymph nodes. All cases except one were surgically treated, and recurrence was found in two cases. Four of nine patients were followed up without recurrence and one patient underwent additional surgery due to recurrence. Conclusion: In our case series, notable symptoms included pain, edema, mouth-opening limitations, and dysesthesia; however, it was difficult to label these as specific symptoms of leiomyosarcoma. Considering the aggressive characteristics of the disease and poor prognosis, surgical treatment is necessary with careful consideration of postoperative radiotherapy and chemotherapy.
