Hypercalcemia of malignancy due to metastatic gastric adenocarcinoma is extremely rare; in fact, to the best of our knowledge, only three case reports of hypercalcemia associated with metastatic gastric adenocarcinoma have been published in the literature to date. Herein, we report a rare case involving a 61-year-old African-American female who had hypercalcemia at initial presentation and who was later diagnosed with poorly differentiated gastric adenocarcinoma with extensive liver metastases, without bone involvement. She was found to have elevated parathyroid hormone-related peptide and normal parathyroid hormone levels. Despite aggressive treatment, she died within a few months of diagnosis.

Metastatic tumors to the jaw bones are uncommon. The most common metastatic tumors to the jaw bones are the breast, lung and kidney. In the jaw bones, the common location of the lesions is the mandible, and the posterior area of the mandible is more commonly affected. The radiographic appearance is quite variable. In this report, a very rare case of metastatic gastric adenocarcinoma to the mandible is presented. The patient had undergone a gastrectomy 3 years ago.

The development of skin metastasis is usually a morbid prognostic feature although they occur infrequently. Adenocarcinomas account for up to about 70% of all metastatic skin cancer. In general, adenocarcinomas are the most difficult metastatic tumor to accurately identify the primary site because they don't have distinctive histological features. For this reason, immunohistochemistry have been used to help identify the origin of metastatic adenocarcinomas. This study performed immunohistochemical staining with metastatic adenocarcinomas of the skin using a variety of antisera to find out characteristic immunohistochemical findings of them. This study was made upon the 29 cases of metastatic adenocarcinomas of the skin, which had been confirmed histopathologically in Chonbuk National University Hospital from January, 1986 to April, 2006, Paraffin blocks were colledted and homemade tissue arrays were made. We performed immunohistochemical staning using 12 antibodies (MUC1, 2, 5AC, 6, cytokeratin (CK) 7, 20, thyroid transcription factor-1 (TTF-1), estrogen receptor (ER), progesterone receptor (PR), beta-catenin, cox-2, claudin-1). The mean age at the time of diagnosis was 60.7 years and the male to female ratio was 1.2:1.0. The most common primary site was lung, followed by stomach and colorectum. MUC1 was expressed by most colorectal, breast and lung adenocarcinoma. MUC2 was expressed infrequently. MUCSAC was expressed by most gastric and colorectal cancer MUC6 was not specific of any primary site in this series. CK7+/CK20+immunophenotype was observed in gastric, lung, colorectal adenocarcinoma. CK7+/CK20- immunophenotype was observed in breast, lung, endometrial, uterine cervical, bile duct adenocarcinoma, while CK7-/CK20+ immunophenotype was observed only in colorectal adenocarcinoma. This results show the utility of TTF-1 to confirm the pulmonary origin. On the other hand ER and PR were not useful markers to assess the origin of primary tumor in this series.

Gastric cancer is the most common cancer in Korean males and can easily spread to distant organs such as the liver, lungs, brain, or bones. However, skin metastasis, particularly of the eye, is rare. Metastatic eyelid cancer is extremely rare; metastases from internal organs have not been reported so far. We recently experienced a patient with metastatic eyelid cancer from adenocarcinoma of the stomach. A 62-year-old female was admitted with a right upper eyelid mass and foreign body sensation. She had a history of stomach cancer of 3 years. She was treated by chemotherapy and radiotherapy for pathologic fracture. After receiving supportive care for 2 years, the mass appeared on her right pupil. Punch-biopsy of the mass was performed and histological examination revealed adenocarcinoma, the same as the initial histological result. We report this case with a review of related literature.

Gastric metastasis from ovarian cancer is rarely reported worldwide. In Korea, only 2 such cases have been reported. Here we report a case of a 58-year-old woman with metastatic gastric cancer from an ovarian adenocarcinoma. Endoscopic examination showed that the cancer presented as a submucosal tumor without ulceration. A subsequent gastrectomy confirmed the diagnosis of metastatic ovarian serous adenocarcinoma.

Neurofibromas are benign tumors that originate from the peripheral nerves, including neurites and fibroblasts. Generally, a solitary neurofibroma is located in the skin and rarely in other places. A 72-year-old female suffered from epigastric discomfort for 2 months. Endoscopic findings showed an early gastric cancer type IIc at the antrum. Abdominal computed tomography revealed early gastric cancer with a 1.6 cm-sized metastatic node posterior to the duodenum. Laparoscopic assisted distal gastrectomy and retro-pancreatic dissection were performed uneventfully. Histological examination revealed gastric adenocarcinoma, invading the mucosa without nodal metastasis, and a neurofibroma. Herein, we present a case of a gastric cancer patient with a solitary retroperitoneal neurofibroma which mimicked a distant metastatic node.

Hepatic metastasis of early gastric cancer (EGC) following subtotal gastrectomy with lymphadenectomy is rare. We report the case of a 61-year-old male patient who was diagnosed with EGC that was initially treated using endoscopic submucosal dissection (ESD) and subsequently underwent laparoscopic subtotal gastrectomy. Histopathological examination of the patient's ESD specimen showed a moderately differentiated tubular adenocarcinoma invading the submucosa without lymphatic invasion. The deep margin of the specimen was positive for adenocarcinoma, and he subsequently underwent laparoscopic distal gastrectomy. The patient developed liver metastasis 15 months after the operation and then underwent liver resection. Histology of the resected specimen confirmed the diagnosis of two foci of metastatic adenocarcinoma originating from stomach cancer. Immunohistochemical analysis of the specimen demonstrated overexpression of human epidermal growth factor receptor 2. The patient was treated with trastuzumab in combination with chemotherapy consisting of capecitabine and cisplatin. Twenty-four months after the operation, the patient remained free of recurrence.

We report the case of a patient with gastric adenocarcinoma with multiple liver metastases. This patient showed complete remission for more than 68 months after S-1/cisplatin combination chemotherapy and radical total gastrectomy. The patient, a 63-year-old man, presented with dyspepsia and difficulty in swallowing. Endoscopic findings showed a huge ulcero-infiltrative mass at the lesser curvature of the mid-body, extending to the distal esophagus. Biopsy revealed a poorly differentiated tubular adenocarcinoma. An abdominal computed tomography scan demonstrated multiple hepatic metastases. S-1/cisplatin combination chemotherapy was initiated, and following completion of six cycles of chemotherapy, the gastric masses and hepatic metastatic lesions had disappeared on abdominal computed tomography. Radical total gastrectomy and D2 lymphadenectomy combined with splenectomy were performed. The patient underwent three cycles of S-1/cisplatin combination chemotherapy followed by tegafur-uracil therapy for 1 year. He remained in complete remission for more than 68 months after surgery.

A case of gastric adenocarcinoma signet ring cell type was described in a ten-year-old female Jindo dog having about three months history of vomiting, anorexia and weight loss. On radiology, ultrasonography and computed tomography, thickness of the gastric fundus was irregularly increased. On necropsy, the gastric fundus was markedly thickened and gastric rugae were attenuated. The cardia and distal esophagus were also thickened. On histopathology, the mucosa was obliterated by neoplastic proliferation of round to polyhedral cells. The neoplastic cells had abundant vacuolated cytoplasm containing mucin. The neoplasm was infiltrated into the submucosa and muscle layer. Metastatic focus was not observed.

Gastric metastasis from ovarian carcinoma is extremely rare and the prognosis for patients is poor. We report a case of multimodal treatment improving the survival time of a patient with gastric metastasis from ovarian cancer. A 73-year-old woman with known serous ovarian cancer was admitted to the hospital due to epigastric pain and dyspepsia. On esophagogastroduodenoscopy, a protruding mass was noted at the gastric antrum. She underwent distal gastrectomy with Billroth I anastomosis and lymph node dissection, including the para-aortic lymph nodes. The final pathology revealed gastric metastasis from ovarian serous adenocarcinoma. In this case, after cytoreductive surgery, chemotherapy was performed each time a recurrence was diagnosed, and remission was accomplished. She survived for 108 months after the first diagnosis of the metastatic tumor in the stomach. Multimodal treatment of metastatic lesions since the first diagnosis allowed the patient to survive longer than those in previous reports.
