Follicular thyroid cancer(FTC) accounts for about 10-15% of thyroid cancer. Distant metastasis is common, usually to lung, bone and brain. 71-years-old man visited neurosurgery outpatient department. He complained of recent 6kg weight loss, left upper extremity pain with weakness and back pain. The radiologic findings showed multiple bone metastasis including thoracic spine and left scapular resulting from FTC. There was a probable brain metastatic lesion on right temporal fossa. The core biopsy of thyroid and thoracic spine(T11) confirmed metastatic follicular carcinoma. Radioactive iodine therapy and radiotherapy was done following total thyroidectomy. We report a unique case of multiple bone metastasis from follicular carcinoma of thyroid with literature review.

Isolated metastasis in the extraocular muscle (EOM) is uncommon, while metastases in bilateral multiple EOMs is even rarer. Rhabdomyosarcoma (RMS) is a rare soft-tissue malignancy that usually occurs in the pediatric population and is one of the primary malignancies of isolated EOM metastasis. Here, we present a case of sinonasal RMS metastasis to multiple bilateral EOMs along with a brief review of 10 previously reported cases of RMS metastasis in EOMs.

A 67-year-old male was admitted due to abdominal pain. Abdominal CT scan performed in a local clinic showed about 2 cm sized pancreatic tail mass with extensive liver and multiple regional lymph node metastasis. Histology of liver biopsy revealed poorly differentiated adenocarcinoma. He underwent chemotherapy with gemcitabine and erlotinib for 5 cycles followed by 8 cycles of second line chemotherapy with 5-fluorouracil and cisplatin. At 12 months after diagnosis, follow-up abdominal CT scan revealed marked reduction of tumor mass in the liver and pancreas with small residual tumor. After one month of last chemotherapy, he complained radiating pain along left leg. Blood chemistry revealed isolated elevation of alkaline phosphatase (ALP) and multiple bone metastasis were demonstrated in bone scan. Palliative radiation therapy to pelvic bone was performed for the relief of bone pain. The prognosis of advanced pancreatic cancer is extremely poor. We report late occurrence of multiple bone metastasis in a patient with well controlled advanced pancreatic cancer with chemotherapy.

Metastasizing mixed tumors [MMT] of salivary glands are inexplicably metastasize maintaining benign histology. There is no pathologic and flow cytometric analysis criteria to predict the metastasis. MMT is known to metastasize by local implantation, vascular and lymphatic embolization after multiple surgery to local recurrences of primary tumor. However, multiple metastasis including cranium and spine occurred even without surgery to the primary tumor in this case. No pathological evidence of malignancy could be found in both primary and metastatic tumor. MMT is considered as an low grade malignancy based on clinical behavior rather than histologic evidence, such as low mortality rate, long delay of metastasis after primary lesion. Cranial metastasis is also extremely rare and only two cases have been reported. We report this unusual case with a literature review.

Multiple bone metastases are common manifestation of many malignant tumors such as lung cancer, breast cancer, prostate cancer and renal cell carcinoma. Bone metastasis is secondary cancer in the bone, and it can lead to bone pain, fracture, and instability of the weight bearing bones, all of which may profoundly reduce physical activity and life quality. Treatment for bone metastasis is determined by multiple factors including pathology, performance status, involved site, and neurologic status. Treatment strategies for bone metastasis are analgesics, surgery, chemotherapy and radiotherapy. External beam radiotherapy has traditionally been an effective palliative treatment for localized painful bone metastasis. However, in some cases such as multiple bone metastases, especially osteoblastic bone metastasis originated from breast or prostate cancer, the radiopharmaceutical therapy using $^{89}Sr$, $^{186}Re$, $^{188}Re$, $^{153}Sm$ and $^{117m}Sn$ are also useful treatment option because of administrative simplicity (injection), few side effects, low risk of radiation exposure and high response rate. This article offers a concise explanation of the radiopharmaceutical therapy for multiple bone metastases.

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.

An unusual case of primary leiomyosarcoma at the left lower posterior chest wall with metastasis to the right lung parenchyme is presented. The patient was a 43-year-old man who was asymptomatic but a slow growing hard mass was noted at the left lower posterior chest wall. The chest computed tomography showed a tumor at the left lower posterior chest wall with multiple metastasis to the right lung. The left lower posterior chest wall mass was examined by percutaneous needle aspiration and it was revealed as rhabdomyosarcoma histologically. En bloc resection to the left lower posterior chest wall tumor and metastasectomy to the multiple nodules in the right lung were done and pathological examination finally revealed primary leiomyosarcoma at the left lower posterior chest wall with multiple metastasis to the right lung. Chemotherapy was scheduled as adjunctive measure.

Background: This systematic analysis was conducted to investigate pathological diagnosis of vertebral tumor metastasis with unknown primaries. Methods: Clinical studies conducted to pathologically investigate vertebral tumor metastasis were identified using a predefined search strategy. Pooled diagnosis (PD) of each pathological confirmation was calculated. Results: For vertebral tumor metastasis, 5 clinical studies which included 762 patients were considered eligible for inclusion. Systematic analysis suggested that, for all patients with vertebral tumor metastasis, dominant PD was pathologically confirmed with lung cancer in 21.7% (165/762), with breast cancer in 26.6% (203/762) and with prostate cancer in 19.2% (146/762). Other diagnosis that could be confirmed included lymphoma, multiple myeloma, renal cancer, for example, in this cohort of patients. Conclusions: This systemic analysis suggested that breast, lung and prostate lesions could be the most common pathological types of cancer for vertebral tumor metastasis formunknown primaries, and other common diagnoses could include lymphoma, multiple myeloma, renal cancer.

Intravenous leiomyomatosis is a rare disease entity of benign smooth muscle invading into the lumen of veins. We describe a case of intravenous leiomyomatosis originating from the uterus, growing in the inferior vena cava, and extending into the right ventricle association with multiple pulmonary metastasis. A 53-year-old woman with chest discomfort and several times attacks of syncope was treated at our hospital. The tumor was successfully removed with moderate hypothermic cardiopulmonary bypass after total hysterectomy with a bilateral salphingo-oophorectomy, and multiple pulmonary metastasis under simultaneous sternotomy and laparotomy was confirmed.

Rhabdomyosarcoma (RMS) is an aggressive and fast-growing malignant tumor. RMS predominantly arises in the head and neck of infancy and children. Metastasis is usually via the blood vessel. We report a case of a recurred RMS of the tongue base with the metastasis to multiple lymph nodes in a 37-year-old female. On the follow-up examination using advanced imaging modalities after surgical treatment of RMS, the lymph nodes should be carefully evaluated like in other malignancies, such as a carcinoma, showing frequent lymph node metastasis.
