Acinic cell carcinoma (ACC) is an uncommon malignant tumor of the salivary glands that is difficult to diagnose. It grows slowly and shows distant metastasis rarely. We experienced a case of recurrent ACC in the parotid gland with cardiac metastasis and hypertrophic osteoarthropathy. The 29-year-old man had been suffering from severe multiple bones and joints pain for 2 months. Ten years earlier, he underwent superficial parotidectomy due to a right subauricular mass. The mass was diagnosed with ACC. After surgery, the tumor recurred twice. Then the patient was diagnosed with cardiac metastasis via positron emission tomography-computed tomography and trans-thoracic echocardiography. He also had hypertrophic osteoarthropathy with multiple bone metastasis. He was given palliative radiotherapy and conservative treatment. ACC in the parotid gland with cardiac metastasis and hypertrophic osteoarthropathy has not yet been reported in literature. From this case, it is recommended to evaluate multiple distant metastasis in the ACC of the parotid gland when joint and bone pain are present.

심장 종양은 매우 드물고 다양한 영상의학적 소견을 보이나 영상 소견만으로는 감별이 쉽지 않다. 저자들은 영상 소견으로 감별이 어려웠던 두 증례인, 드문 원발성 심장 림프종양과 전이성 심장암 증례에 대하여 보고하고자 한다.

We report a case of a 13-year-old girl with acute lymphoblastic lymphoma- leukemia, who presented with a cardiac metastasis in the right ventricle, resulting in a pulmonary embolism. At the time of her leukemia diagnosis, a cardiac mass was incidentally found. The differential diagnosis for this unusual cardiac mass included cardiac tumor, metastasis, vegetation, and thrombus. Empirical treatment was initiated, including anticoagulation and antibiotics. She underwent plasmapheresis and was administered oral prednisolone for her leukemia. Five days later, she experienced sudden hemodynamic collapse and required extracorporeal membrane oxygenation insertion and emergency surgery. These interventions proved futile, and the patient died. Pathology revealed that the cardiac mass comprised an aggregation of small, round, necrotic cells consistent with leukemia. This is the first known case of acute lymphoblastic leukemia presenting as a right ventricular mass, with consequent fatal acute pulmonary embolism. A cardiac mass in a child with acute leukemia merits investigation to rule out every possible etiology, including vegetation, thrombus, and even a mass of leukemic cells, which could result in the fatal complication of pulmonary embolism.

Objective: Arrestins act as mediators of G protein-coupled receptor (GPCR) desensitization and trafficking, also actin as a scaffold for many intracellular signaling network. The role that ${\beta}$-arrestin 1 plays in gastric cardiac adenocarcinoma (GCA) and its clinicopathologic significance are untouched. Methods: Fifty patients with gastric cardiac adenocarcinoma were retrospectively enrolled and ${\beta}$-arrestin 1 was detected using immunohistochemistry in tissue samples. Results: Nuclear expression of ${\beta}$-arrestin 1 was observed in 78% of GCA samples (39/50) and cytoplasmic expression in 70% (35/50). ${\beta}$-arrestin 1 could be found in both nucleus and cytoplasm of 54% GCA (27/50) or in either of them in 94% (47/50). ${\beta}$-arrestin 1 protein positivity in well/moderately differentiated carcinomas was significantly higher than that in poorly differentiated carcinomas (P=0.005). We found increased expression of ${\beta}$-arrestin 1 in cytoplasm was correlated with lymph nodal metastasis (P=0.002) and pathological lymph nodal staging (P=0.030). We also found ${\beta}$-arrestin 1 to be over-expressed in glandular epithelia cells of mucinous adenocarcinoma, a tumour type associated with an adverse outcome of gastric cardiac adenocarcinoma (P=0.022). Conclusion: ${\beta}$-arrestin 1 is over-expressed in the nucleus and/or cytoplasm of gastric cardiac adenocarcinoma. However, ${\beta}$-arrestin 1 has no relationship with the prognosis of gastric cardiac adenocarcinoma (P>0.05). Our data imply that ${\beta}$-arrestin 1 in cytoplasm may be involved in differentiation and metastasis of gastric cardiac adenocarcinoma.

Background: Malignant primary cardiac tumors are extremely rare, but have a poor prognosis. This study evaluated the surgical outcomes of patients with this disease. Methods: Forty patients who underwent surgery for malignant primary cardiac tumors between January 1998 and December 2018 were enrolled. Participants were divided into 3 groups based on resection margins (R0, 14 patients; R1, 11 patients; and R2, 11 patients) and their surgical outcomes were compared. Heart transplantation was performed in 4 patients with unresectable tumors. Results: Early mortality was reported in 2 cases (5%) due to postoperative bleeding and cerebral hemorrhage secondary to brain metastasis. The 1- and 2-year survival rates were 67.5% and 42.5%, respectively. The median survival time of the patients was 20.3 months (range, 9.2-37.6 months). The median survival time was 48.7, 20.3, and 4.8 months in patients with R0, R1, and R2 resections, respectively (p=0.023). Tumor recurrence occurred in 21 patients (61.7%), including 4 cases of local recurrence and 17 cases of distant metastasis. In patients who underwent heart transplantation, the median survival time was 29.5 months, with 3 cases of distant metastasis. Conclusion: Although surgery for malignant primary cardiac tumors has a poor prognosis, complete resection of the tumor may improve surgical outcomes.

심장점액종은 심장의 가장 흔한 양성 종양이다. 하지만 국소전이와 원격전이의 증례들이 낮은 빈도로 보고되어 있다. 뇌경색을 주소로 내원한 49세 여자 환자의 심장초음파에서 심장 점액종이 발견되었으며 수술로 절제 1년 후에 구음장애가 발생하여 촬영한 자기공명영상에서 여러개의 조영증강이 되는 출혈성뇌전이 병변들이 관찰되었다. 방사선치료 후 추적 자기공명영상에서 병변의 크기들이 작아지는 것을 확인할 수 있었다. 양성 종양이지만 심장 점액종은 드물게 지연되어 전이를 보일 수 있다. 저자들은 심장 점액종을 수술로 완전히 절제 후 지연되어 나타난 뇌전이를 경험하여 증례 및 문헌고찰을 하는 바이다.

평활근육종은 평활근육세포에서 기원하는 연부조직 육종이다. 평활근육종은 자궁에 흔하게 발생하지만 후복막강, 복강 그리고 혈관조직에도 발생할 수 있다. 자궁 또는 혈관에서 기원하는 평활근육종이 심장에 전이된 증례는 많이 보고되었으나, 내장 외 연부조직에서 생긴 평활근육종은 매우 드물게 발생하며 심장으로의 전이는 더욱 드문 것으로 알려져 있다. 이에 좌측 측복부에서 우심실로 전이된 평활근육종의 심초음파 소견과 조영증강 컴퓨터단층촬영소견을 경험하여 보고하고자 한다.

원발성 심장종양은 희귀성 때문에 병리학자, 심장내과의, 심장외과의에게 흥미로운 질환이다. 저자들은 수술치험한 세계적으로 희귀한 원발성 심장 연골육종을 보고하는 바이다. 환자는 37세의 여자환자로 본원에서 좌심방종양진단하에 1993년 6월 3일 입원하여 개심술하에서 완전 종양절제를 받은 바 있다. 그러나 조직소견상 연골육종이 진단되어 수술후 보조요법으로 방사선조사와 화학요법을 받은후 추적관찰하던 중 1995년 5월까지 종양 재발소견은 없었다. 그러나 환자는 두통과 전신성 경련으로 본원 신경외과에 입원하여 검사상 대뇌 전두엽부위에 단일 전이성 종괴가 발견되어 개두술하 종양절제가 가능하였으며, 조직 검사상 심장종양과 일치를 보였다. 환자는 건강한 상태로 퇴원하였다.

An intramedullary spinal cord metastasis (ISCM) rarely develops in systemic cancer but is indicative of a poor prognosis. A 56-year-old man was admitted due to weakness of the lower extremities. He had received radiotherapy 3 months prior for a brain metastasis that had developed 1 year after achieving a complete response from chemotherapy for extended stage small cell lung cancer. Although the brain lesion had improved partially, ISCM from the cervical to lumbar-sacral spinal cords, which was accompanied by a leptomeningeal dissemination, was diagnosed based on magnetic resonance imaging of the spine and cerebrospinal fluid cytology. Finally, he died of sudden cardiac arrest during treatment. This is the first case of ISCM involving the whole spinal segments. Physicians should be aware of the subsequent development of ISCM in lung cancer patients with a previously known brain metastasis who present with new neurological symptoms.

Although neoplastic involvement of the pericardium is frequently present postmortem, cardiac manifestations before death are uncommon, and cardiac tamponade as the initial presentation of cancer is rare. We are presenting a metastatic pericardial tumor with cardiac tamponade of unknown primary neoplasm. The patient brought to hospital in a state of unconscious. The chest x-ray film showed cardiomegaly with a globular heart shape and right pleural effusion. We underwent an anterior thoracotomy and pericardial window was created. The histopathologic finding of pericardium, pleural and pericardial effusion show a metastatic adenocarcinoma. The patient subsequently received adjuvent radiotherapy and chemotherapy, but he expired on the postoperative 132 day.
