Intraperitoneal metastatic hepatocellular carcinoma (HCC) is uncommon. Although rare, it can spontaneously rupture and cause hemoperitoneum similar to primary HCC in the liver. We present a case of intraperitoneal metastatic HCC that had spontaneously ruptured and appeared as an irregularly margined hemorrhagic mass with T1 high and T2 dark signal intensities on magnetic resonance imaging. Ruptured HCC is a life-threatening emergency with high mortality rate. Spontaneously ruptured intraperitoneal metastatic HCC should be considered if a patient with a history of HCC presents with acute abdomen, although rare.

Oral metastatic tumors are uncommon and account for about 1% of malignant oral neoplasm. The metastatic lesions are common in breast, lung, kidney and thyroid cancer. About 20% of oral mucosal metastasis is founded before detection of primary lesions. Usually, the metastatic lesions of the oral cavity are involved in the jaw bone, especially mandible more than the oral soft tissues. We report a case diagnosed as the stomach cancer with mandible metastatic lesion looking like TMJ abscess.

Pancreatic cancer treatment has advanced. In particular, effective chemotherapy regimen development has fundamentally altered the therapeutic concept and strategy for pancreatic cancer treatment. Consequently, the prognosis of patients with pancreatic cancer has gradually improved. Conversion surgery for locally advanced pancreatic cancer may offer long-term survival or even a full recovery in some individuals. In contrast, metastatic pancreatic cancer has long been considered a surgical contraindication because aggressive surgical resection of the metastatic lesions does not prolong patient survival. Unexpectedly positive benefits of anticancer therapy in recent clinical experience were observed even with metastatic pancreatic cancer. To date, little evidence presented the success of surgical resection for metastatic pancreatic cancer treatment in such rare cases. However, hope and concern are growing that surgical intervention, even in patients with metastatic cancer, may result in favorable outcomes. Several studies suggested different surgical intervention effects depending on metastasis sites and patterns. Thus, this review summarizes the current status of surgery in the multidisciplinary treatment of oligometastatic pancreatic cancer and discusses future perspectives.

Metastases to the jawbones are found predominantly in the mandible and are rare in relation to the overall spectrum of oral malignancy. Analysis of the literature shows that the most frequent primary sites are the breast, lung, kidney, thyroid, and prostate. Adenocarcinoma of the mandible, whether primary or metastatic, are usually difficult to diagnose clinically. We report a case illustrating the clinical, radiographic, and histologic findings of a metastatic lung adenocarcinoma of the anterior mandible in a 58-year-old male.

Treatment of metastatic carcinoma of the oral cavity can be a challenge due to its rarity. The current case report details metastatic carcinoma of the mandible originating from follicular thyroid carcinoma, which is the second most prevalent tumor of the thyroid. As the mandibular lesion developed, the primary thyroid lesion of thyroid. Here, we report a case of metastatic carcinoma of the mandible in a 67-year-old female that was treated with partial mandibulectomy and fibular free flap.

경화성 혈관종으로 흔히 부르는 폐세포종(pneumocytoma)은 간혹 다발성으로 발생한 예가 보고되나 림 프절로 전이된 예는 문헌상 세계적으로 1예만이 보고되었다. 연세의대 흉부외과에서는 29세의 남자에서 우연히 발견된 우측 폐문부 폐종괴를 수술전 폐암(선암) 진 단하에 우상엽폐절제술 및 림프절박리술을 시행한 결과, 조직병리검사상 림프절 전이를 동반한 폐세포종 을 경험하였다. 폐세포종은 양성 종양으로 알려져 있으나 매우 드문 경우에서 전이할 수 있음을 보였다.

A sex cord tumor with annnular tubules is a relatively rare ovarian neoplasm. The cytologic findings from a fine needle aspiration biopsy of neck metastasis of a sex cord tumor with annnular tubules are described. The origin of the neck metastasis was the right ovary, and the tumor was diagnosed six years ago. The cytologic findings were characterized by tumor cells arranged in solid or follicular patterns. The tumor cells formed rosette-like or complex tubular structures with central rounded or coalesced hyaline materials. It was difficult to distinguish this tumor cytologically from granulosa cell tumor, thyroid follicular neoplasm, Sertoli-Leydig cell tumor, and Brenner tumor, but complex tubular structures were helpful in discriminating between these tumors.

A six year old female Shih Tzu was euthanized after having about 2 months history of weakness and convulsion with hypoglycemia. On ultrasonography, several masses in variable sizes were noted in the liver and fine needle aspiration cytology revealed probable neoplasm of pancreatic origin. On necropsy, numerous round firm tan nodules with central depression were noted in the liver and heart. Mesenteric lymph node was enlarged and fused with presumable pancreatic tissue. Based on the histopathology and immunohistochemistry, the tumor was confirmed as malignant metastatic insulinoma.

Background: To investigate factors associated with overall survival in patients with newly diagnosed metastatic nasopharyngeal carcinoma. Materials and Methods: Two hundred and two consecutive patients with pathologically confirmed nasopharyngeal carcinoma with distant metastasis at diagnosis seen between December 2007 and May 2011 were reviewed. Patient, tumor and treatment factors were analyzed for their significance regarding overall survival. Results: The median follow-up time was 22 months. At the time of this report, 116 patients had died. For 112 patients, cause of death was nasopharyngeal carcinoma. The 1, 2, 3, and 4-year overall survival rates were 75.6%, 50.2%, 39.2%, and 28.2%, respectively. Cox regression multivariate analysis showed that T-stage (p=0.045), N-stage (p=0.014), metastasis number (p<0.001) and radiotherapy for nasopharynx and neck (p<0.001) were significant factors for overall survival. Conclusions: Early T-stage and N-stage, solitary metastasis in a single organ were good prognostic factors for patients with newly diagnosed metastatic nasopharyngeal carcinoma. Radiotherapy should be strongly recommended in systemic treatment.

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.
