Leiomyosarcoma is an uncommon tumor which arises from various sites including uterus, stomach, retroperitoneum, superficial soft tissues, bladder, kidney, and lung. Primary hepatic leiomyosarcoma is a very rare tumor and fewer than 70 cases of primary hepatic leiomyosarcoma have been reported since the first publication in Japan. And there was only one case report of cutaneous metastasis from hepatic leiomyosarcoma. We recently experienced a case of primary hepatic leiomyosarcoma presenting as subcutaneous palpable mass. Herein we report this case with a review of literatures.

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.

Cutaneous metastases from pancreatic adenocarcinomas are rare lesions. The most common site of cutaneous metastasis is the umbilicus, and this is also known as the 'Sister Mary Joseph' nodule. A 68-year-old Korean male, who was previously healthy and asymptomatic, was seen in the dermatology department for two subcutaneous nodules that he had on his right forearm and his back. Histological examination of the right foreman nodule revealed metastatic adenocarcinoma. Immunohistochemical staining for cytokeratin (CK) 7 and CK 19 were positive, and this strongly suggested the pancreatic duct as being the primary source of the cancer. The abdominal computed tomography findings were compatible with pancreatic cancer. Clinicians should be aware that metastatic cutaneous lesions could be the initial presenting sign for pancreatic cancer. The immunohistochemical staining for CK 7 and 19 may also be helpful in the diagnosis of metastatic pancreatic adenocarcinoma.

Common metastaic sites of hepatocellular carcinoma include lung, peritoneum, adrenal gland and bone, but rarely, skin can be metastatic sites. Although hepatocellular carcinoma is the third commonest malignancy in Korea, cutaneous metastasis from hepatocellular carcinoma was rarely reported. Cutaneous metastasis from malignant neoplasm of the internal organ occur at the variable stage and the growth pattern of cutaneous lesions is nonspecific and various, so the differential diagnosis of skin lesions must be considered to other malignant condition. We report a case of cutaneous metastasis from recurrent hepatocellular carcinoma that was confirmed by skin biopsy with immunohistochemical stain.

The cutaneous metastasis of a visceral malignancy to the umbilicus is known as "Sister Mary Joseph's nodule (SMJN)". It is considered to be a predictor of poor prognosis because it mostly occurs in advanced, metastasizing cancer. However, it is a very rare condition as an initial presenting sign of primary cancer. We recently encountered a 48-year-old man presented with an umbilical lump. The lesion was a firm, ill-delineated, painful nodule with regular surface in the umbilicus. Abdominal computed tomography showed a 2.2 cm sized, ill-defined, delayed enhancing mass at the periumbilical area accounting for umbilical nodule. Diffuse irregular thickening of peritoneum and diffuse wall thickening of stomach implied the diagnosis of gastric cancer. Esophagogastroduodenoscopy revealed diffuse nodular infiltrative lesion from cardia through body of the stomach, compatible with Bormann type 4 advanced gastric cancer. Later, histopathologic confirmation showed a presence of signet ring cell adenocarcinoma from biopsy specimens. We experiened a case presenting with an umbilical metastasis as the first sign of gastric adenocarcinoma. It is thought that direct extension of tumor through the peritoneum might be the route for umbilical metastasis. Careful examination of all umbilical lesions must be needed for the early diagnosis of internal malignancy.

Cutaneous metastases rarely develop in patients with internal malignancy. Cholangiocarcinoma, a malignant cancer of the bile duct, is a relatively rare adenocarcinoma and has a poor prognosis. Few reports have mentioned cutaneous metastases of cholangiocarcinoma, and the most of them were due to direct tumor seeding by percutaneous procedures. Herein, we report a case of cholangiocarcinoma with distant cutaneous metastases in a 60-year-old man.
