Large cell neuroendocrine carcinoma is a rare epithelial neuroendocrine malignancy and is preferentially located in gastrointestinal tract and pancreas. Cases of large cell neuroendocrine carcinoma have been reported in many other locations, including the thymus, gallbladder, prostate, larynx, salivary glands, nasopharynx, tonsil and mastoid. However, primary sinonasal large cell neuroendocrine carcinoma never have been reported in Korea. We experienced a case of primary large cell neuroendocrine carcinoma arising from left maxillary sinus recently. A 82-year-old male patient presented with nasal obstruction and epistaxis. The biopsy revealed large cell neuroendocrine carcinoma with poor differentiation. After a general evaluation, the patient was staged as cT3N0M0. The patient was treated by combined radiotherapy and chemotherapy. We report this rare case with literature review.

대세포 신경내분비암은 드문 질환으로, 최근에 폐의 신경내분비암의 하나로 진단 기준이 확립되었다. 심한 흡연자로 증상이 없는 74세의 남자가 우하엽의 종양을 주소로 내원하였다. 세침 생검을 통해 대세포 신경내 분비암으로 진단되었다. 우하엽 절제술과 종격동 림프절 곽청술을 시행 받았다. 저자들은 대세포 신경내분비암의 한 례를 치험하였고 문헌고찰과 함께 보고한다.

전신쇄약을 주소로 내원한 60세 남자환자가 흉부 방사선 사진상 좌폐하엽에서 폐종양이 발견되었다. 좌폐하엽절제술과 종격동 임파선 절제를 시행후 병리조직검사상 폐의 대세포 신경내분비암으로 진단되었다. 폐의 대세포 신경내분비암은 드문 질환으로 저자들은 이를 치험하였기에 보고하는 바이다.

Mixed neuroendocrine-nonneuroendocrine neoplasms (MiNENs) are a group of rare tumors previously known as mixed adenoneuroendocrine carcinomas (MANECs). The neuroendocrine component is high-grade and may consist of small-cell carcinoma or large-cell neuroendocrine carcinoma. The nonneuroendocrine component may consist of adenocarcinoma or squamous cell carcinoma. We report a unique case of a MiNEN with trilineage differentiation: large-cell neuroendocrine carcinoma, squamous cell carcinoma, and adenocarcinoma. The reported patient presented with symptoms of an upper gastrointestinal bleed and was ultimately diagnosed with a MiNEN with trilineage differentiation. This is the first report of this exceedingly rare tumor type to include next-generation sequencing of the 3 separate tumor entities. In addition, we review the current literature and discuss the role of next-generation sequencing in classifying and treating MiNEN tumors.

A 73-year-old male visited our hospital with a complaint of general weakness. He underwent pyloric preserving pancreas-toduodenectomy due to ampullary cancer three years ago. Abdominal computed tomography scan at initial visit revealed multiple hepatic masses. A PET-CT scan showed multiple FDG uptakes at whole liver. He underwent hepatic artery infusion chemotherapy (HAIC) for five cycles. During the first cycle of HAIC, he developed gastric ulcer bleeding and endoscopic hemostasis was done successfully. Esophagogastroduodenoscopy after the 5^th cycle of HAIC revealed ulcer scar at gastric angle. PET-CT scan at 12 months showed no FDG uptake at liver, but a focal FDG uptakes at stomach and peri-gastric lymph nodes were newly developed. Esophagogastroduodenoscopy revealed about 3 cm sized mass at gastric angle. He underwent surgery and pathologic examination revealed large cell neuroendocrine carcinoma. We report a case of gastric large cell neuroendocrine carcinoma with liver metastasis treated with HAIC followed by surgery.

The major categories of neuroendocrine tumors of lung are typical carcinoid, atypical carcinoid, large cell neuroendocrine carcinoma, and small cell carcinoma. The histologic classification criteria of neuroendocrine tumors are well documented in the "WHO Classification of Tumors" based on mitotic figures and necrosis. Cytologic characteristics of neuroendocrine tumors are trabecular, acinar, and solid arrangement of tumor cells and occasional rosette formation. Nuclear chromatin patterns are characteristically described as "salt and pepper chromatin pattern". Many of cytologic classifications documented in the literature are before the "WHO Classification". In this review, the cytologic features of pulmonary neuroendocrine tumors are documented according to the WHO classification, and recent concepts of neuroendocrine tumors of lung are discussed.

Metastasis of lung cancer to the skin is uncommon, presenting in 0.22% to 12% of lung cancer patients, and it is extremely rare for skin metastasis to be the first clinical manifestation of lung cancer. In the few cases where skin metastasis has been reported as the first sign of lung cancer, the patients were typically heavy smokers or had preexisting respiratory diseases and symptoms. This prompted clinicians to consider skin metastasis of a pulmonary malignancy. Large cell neuroendocrine carcinoma (LCNEC) is a rare type of lung cancer that accounts for approximately 3% of lung cancers. LCNEC mainly metastasizes to visceral organs, such as the liver, bone, and brain, and it only shows metastasis to the skin in very rare cases. Herein, we report an unusual case of a metastatic skin lesion as the first sign of primary pulmonary LCNEC, in a 63-year-old woman with no pulmonary symptoms or personal history of smoking or pulmonary disease.

A large cell neuroendocrine carcinoma (LCNEC) of the thymus is a very rare malignant tumor that has a very poor prognosis. The detailed clinical features of LCNEC are still unknown, including the long term prognoses and the definitive modalities of the treatment for LCNEC of the thymus. We are reporting 2 cases of an enlarged LCNEC of the thymus, both of which were diagnosed and treated by surgical resection followed by postoperative adjuvant chemoradiation therapy. Although recurrences and metastases of the LCNEC were noticed 1 and 4 years postoperatively for each case, aggressive surgical resection and adjuvant chemoradiation therapy may be helpful for a patient's long term survival.
