A 65-year-old male patient presented multiple cutaneous nodules on trunk and an erythematous inflammatory lesion resembling erysipelas on left side of neck. Result of skin biopsies disclosed groups of metastatic adenocarcinoma cells in the dermis, subcutaneous tissue, and lumina of the lymphatic vessels. Histopathologic examination of the stomach, along with the gastroscope, established that the cutaneous metastasis was of stomach origin.

Gastric cancer with liver metastasis (GCLM) is the leading cause of death in patients with advanced gastric cancer. Multiple metastasis was common in GCLM and usually complicated with lesions outside the liver, especially peritoneal metastasis. Most of liver metastasis lesions could not be resected radically. Currently, main treatments for GCLM included radical operation, palliative resection of gastric cancer, ablation of metastatic lesions, intervention and systemic chemotherapy. Based on the current progress in the treatment for GCLM and our clinical experience, the general status of patients, the type of gastric cancer and the degree of liver metastasis should be analyzed, and a cooperative multidisciplinary team (MDT) should be applied to conduct and to choose active and suitable comprehensive treatment for GCLM patients based on individualized therapy principle.

Blood-borne metastatic involvement of the stomach by cancer is a rare entity. According to the number of reports in the literature, the most common tumors that spread to the stomach through the blood stream are malignant melanoma, breast carcinoma and lung carcinoma. Recently, two cases of metastatic involvement of the stomach secondary to lung carcinoma were diagnosed by gastroscopy. The first patient was a 66-year-old man who had primary lung carcinoma with multiple bone and subcutaneous metastases. Gastroscopy showed multiple submucosal tumors with central umbilications in the fundus and in the upper body of the stomach. Pathologic examination revealed massive submucosal infiltration and conical shaped and scanty deep mucosal infiltration of undifferentiated small cell carcinoma suggestive of metastatic involvement. The second patient was a 68-year-old man who had primary lung carcinoma with brain metastasis. Gastroscopy showed a large fungating mass in the greater curvature side of the stomach. Pathologic examination revealed poorly differentiated squamous cell carcinoma. We report the two cases of metastatic gastric cancer from lung carcinoma with the literature review.

The most common metastatic sites of gastric cancer are liver, lung, bone and adrenal gland. However, skin metastases from gastric cancer are relatively rare. We herein report a case of advanced gastric cancer with perianal skin metastasis in a 70-year-old male. On admission, patient presented with epigastric pain. Endoscopy and abdominal CT scan demonstrated the stage IV gastric cancer. He had one painless nodule on perianal skin area, biopsy of that lesion showed a feature of poorly differentiated adenocarcinoma clinically from the stomach. We suspected that the perianal lesion was originated from gastric cancer.

OBJECTIVETo investigate the clinicopathologic characteristics and differential diagnosis of the metastases to the breast from non-mammary malignancies.

METHODSTwenty-eight cases were collected from 2004 to 2012;microscopic pathologic examinations and immunohistochemistry (EnVision method) were performed.

RESULTS(1) All except one patients were female, ranging from 16 to 77 years old (average 45.8 years). Twenty-six (92.9%) patients initially presented with the primary site lesions; while the other two (7.1%) patients initially presented with breast lesions. The mean interval from primary diagnosis to detection of metastatic breast lesions was 32 months (0-228 months). Fifteen patients (53.6%) had other metastases detected simultaneously or preceded the breast lesions. (2) Macroscopically, all the tumors were relatively circumscribed, with a mean diameter of 4.0 cm (0.6-12.0 cm). The histological types of the corresponding primary tumors were as follows: eight (28.6%) cases from lung adenocarcinoma, five (17.8%) from high-grade ovarian serous carcinoma, three (10.7%) from gastric adenocarcinoma, two (7.1%) from rectal adenocarcinoma, one (3.6%) from pancreatic neuroendocrine carcinoma, one (3.6%) from prostatic carcinoma, four (14.3%) from melanoma, and four (14.3%) from mesenchymal malignant tumors (three rhabdomyosarcomas and one epithelioid malignant peripheral nerve sheath tumor, MPNST). (3) Histologically, the metastatic tumors showed the morphologic characteristics of the primary tumors. Lymph-vascular invasion was observed in 19 cases. Immunohistochemical features of metastatic tumors were consistent with the primary tumors. Molecular markers for breast such as GCDFP15 and mammaglobin were negative. Metastatic tumors from lung adenocarcinoma expressed TTF-1 (8/8). Ovarian serous carcinoma metastases were positive for PAX8 (5/5) and WT1 (4/5). Gastric adenocarcinoma metastases were positive for CDX2 (3/3) and villin (1/3). Rectal adenocarcinoma metastases were positive for CDX2 (2/2). Pancreatic neuroendocrine tumor metastasis was positive for Syn and CgA (both 1/1). Prostate carcinoma metastasis was positive for AR, PSA and P504S (all 1/1). Melanoma metastases were positive for HMB45 (2/3) and S-100 protein (3/3). Rhabdomyosarcoma metastases were positive for vimentin, desmin and myoD1 (all 3/3). MPNST metastasis was positive for S-100 protein (1/1). (4) Follow-up data was available in 17 patients, with median follow-up time 54 months. The median survival from diagnosis to breast metastasis was 24 months.Seven of 17 patients died.

CONCLUSIONSMetastases to the breast from non-mammary malignancies are rare and show pathologic features of primary tumors. It is usually presumed to be a primary breast carcinoma. Histopathologic features and clinical history in conjunction with the immunohistochemical results should be considered in differentiating a secondary mass from a primary breast carcinoma.

Gastric metastasis of lung carcinoma is a rare entity which is detected mostly at autopsy. Patients diagnosed as having those on lifetime are extremely rare. In addition to our case, 54 cases of lung carcinoma metastasis to the gastro-intestinal tract have been reported in the literature since 1961. We report a case of gastric metastasis originated from small cell lung carcinoma. The patient was a 87-year-old man. He refused lung biopsy and further treatment and died 2 months after the diagnosis. This is the case of gastric metastsis originated from lung carcinoma, which was confirmed by immunohistochemical staining.

Metastatic tumors to the nasal cavity and paranasal sinuses are far less common than primary cancer in this location. The digestive system malignant tumor metastasis to the nose is rarer. The clinical presentation of metastases is similar to that of primary tumors and common symptoms include recurrent epistaxis, nasal obstruction and facial pain. Metastases to the nose and paranasal sinuses usually respond poorly to treatment and have a poor prognosis.

OBJECTIVETo assess the long- term efficacy of surgical treatment of hepatic metastases from gastric adenocarcinoma.

METHODSClinical data of 938 cases with primary gastric cancer from January 1993 to October 2001 were analyzed retrospectively. Thirty- two cases received resection of hepatic metastases from gastric adenocarcinoma.

RESULTSMetachronous hepatic metastasis occurred in 24 cases(2.6% ),and 14 cases(58.3% ) underwent resection of hepatic metastases, while synchronous hepatic metastasis occurred in 90 cases(9.6% ) and 18 cases(20% ) underwent resection of hepatic metastases. The 1- 3- 5- year survival rates of hepatic resection for metachronous hepatic metastases were 73% 37% 25% respectively; while for synchronous hepatic metastases 68% 24% and 17% respectively. There were no significant differences between the two groups (P> 0.05).

CONCLUSIONSynchronous and metachronous hepatic metastases from gastric cancer should be treated by surgical resection to confirm a better prognosis.
