We present a case of a 55-year-old woman who complained of chest pain at rest. A mass was detected adjacent to her left atrium. The mass was completely excised, and a pathologic examination revealed it to be a schwannoma. Schwannomas are tumors that originate in the nerve sheath and are rarely detected in the heart. Here, we describe a rare case of primary schwannoma of the left atrium.

Sebaceous carcinoma is a malignant neoplasm that usually arises in the sebaceous glands of the eyelids. Its pathogenesis is unknown; however, irradiation history, immunosuppression, and use of diuretics are known risk factors. The mainstay of treatment for sebaceous carcinoma of the eyelid is wide surgical resection with a safety margin of 5 to 6 mm, which often results in full-thickness defects. The reconstruction of a full-thickness defect of the eyelid should be approached using a three-lamella method: a mucosal component replacing the conjunctiva, a cartilage component for the tarsal plate, and a flap or skin graft for the skin of the eyelid. In this case, a full-thickness defect of the upper eyelid was reconstructed after tumor removal using a combination of a nasal septum chondromucosal composite graft and a forehead transposition flap, also known as a "Fricke flap." The flap was designed to include a line of the eyebrow on the lower margin of the flap to replace the eyelash removed during tumor excision. The wound healed completely, without any early or late complications, and the outcome was satisfactory.

Chondrosarcoma is a rare entity of malignant tumor which arises from cartilaginous tissue, and the literatures on this disease are scarce. The first-line of treatment for cardiac chondrosarcoma is surgery. Due to early local recurrence and distant metastasis, the prognosis is poor even after complete surgical excision. We present a case of chondrosarcoma in the left atrium causing functional mitral stenosis which required urgent surgical intervention, and the successful treatment outcome.

신경초종은 슈반세포에서 기원하는 양성 종양이며 말초신경집에서 생기는 가장 흔한 종양이다. 신경초종은 신체 어디에서나 발견될 수 있으나, 보통 머리와 목, 그리고 사지의 굽힘 면에서 흔하게 보일 수 있는 종양이다. 췌장은 신경초종이 드물게 생기는 위치이며 적은 수의 증례가 보고되었다. 보고된 신경초종 증례의 약 3분의 2 정도에서 낭성변화를 동반한다. 따라서 적절한 진단과 치료를 위해서는 췌장에서 발견되는 낭성변화를 동반한 고형 종양의 경우 신경초종이 감별진단에 포함되어야 한다. 이에 저자들은 병리학적으로 진단된 낭성변화를 동반한 췌장의 신경초종을 문헌고찰과 함께 보고하고자 한다.

유두상 섬유탄력종은 양성 심장 종양 중 두번째로 많이 발생하며, 주로 대동맥 판막이나 승모판막에 발생한다. 그러나, 폐동맥 판막에서 발생한 경우는 아주 드물게 보고되고 있다. 이에 저자들은 심부전증 환자에서 판막 치환술로 치료된 폐동맥 판막의 유두상 섬유탄력종을 드문 증례로 보고하는 바이다.

An ectopic thyroid is caused by abnormalities in migration of the thyroid during development and rarely occurs in the thoracic cavity or the abdominal cavity. We report the case of a 64-year-old female who had abnormal findings from a thyroid hormone test during follow-up after thyroid cancer surgery. Based on the radioisotope diagnostic test, an ectopic thyroid inside the thoracic cavity was suspected. Through surgical treatment, the patient was diagnosed with ectopic intrapulmonary thyroid. Ectopic intrapulmonary thyroid is reported to be very rare and the case is described along with a literature review.

Malignant peripheral nerve sheath tumors are rare sarcomas of the heart. Herein, we report the case of a 24-year-old man who complained of dyspnea, cough, and upper left back pain. He was found to have multiple primary heart tumors obstructing the right superior pulmonary vein in the left atrium, which were diagnosed as malignant peripheral nerve sheath tumors. The patient underwent successful resection of the tumors and immunohistochemistry was utilized for diagnosis.

Pancreatic cancer is a highly fatal malignancy with a 5-year survival rate of < 10%. Endoscopic ultrasound (EUS) is a useful noninvasive tool for differential diagnosis of pancreatic malignancy and treatment decision-making. However, the performance of EUS is suboptimal, and its accuracy for differentiating pancreatic malignancy has increased interest in the application of artificial intelligence (AI). Recent studies have reported that EUS-based AI models can facilitate early and more accurate diagnosis than other preexisting methods. This article provides a review of the literature on EUS-based AI studies of pancreatic malignancies.

Background: Free-flap reconstruction for recurrent head and neck cancer may be challenging depending on the previous treatments, those are, chemotherapy, radiotherapy, and surgery, including neck dissection or free tissue transfer. Specifically, the previous treatment could compromise the neck vessels, thereby making free-flap reconstruction more difficult. This study aimed to investigate the correlation between previous treatments and vascular compromise of the free flap. Methods: In this retrospective study, 124 free-flap reconstructions in 116 patients for recurrent head and neck cancer between 1993 and 2017 were investigated. The demographic characteristics, previous treatments, flap choices, infections, recipient vessels, and vascular crises were evaluated. Results: Of the 124 reconstruction cases, 10 had vascular crises. There were six revisions, totaling six flap failures. The success rate of free-flap reconstruction for recurrent cancer was 95.2%, which significantly differed from that for primary cancer (98.8%, p= 0.006). Moreover, in the recurrent cancer group, no correlation was found between previous treatments and vascular crises (p> 0.05). Increased rates of contralateral or uncommon anastomoses were found following neck dissection (p< 0.05). Conclusion: Previous neck dissection or radiotherapy could lead to scarring and tissue damage, which could in turn make microvascular reconstruction more challenging; however, the effect was not definite in this study. Approximately 60% of patients with previous neck dissection had compromised ipsilateral recipient vessels, which resulted in contralateral or uncommon anastomoses. In this study, free-flap reconstruction seems to be quite safe and preferable in patients with recurrent head and neck cancer based on the overall survival rate.
