Colorectal carcinoma is a common malignancy in India as well as in world. Inspite of its high metastasizing ability to various organs and lymph node, orbital metastasis is exceptional. Very few cases have been reported in the world literature. We report orbital metastasis in a case of moderately differentiated rectal adenocarcinoma in a 58-year male patient from India in 2015. We want to focus ...

metastasis to the oral region is very rare and accounts for less than 1% of oral malignant tumors. breast, lung, kidney, adrenal, gastro intestinal tract and prostates are most common primary tumors from which metastasis to oral region occur frequently. metastasis from thyroid gland is extremely rare to oral region. we present an unusual case of metastatic follicular carcinoma of thyroid in max...

myxoid is a common type of liposarcoma. cardiac metastasis of sarcoma is a rare diagnosis. transthoracic echocardiography is a useful tool for beginning the diagnosis. curative resection of metastasis and then combination systemic chemotherapy for advanced disease is recommended. we report a 50 year old woman who presented with a cardiac metastasis of high grade round cell liposarcoma to right ...

meningioma is usually a benign central nervous system (cns) tumor. metastasis is rare; however if it does occur the most metastatic sites are the liver and lungs. here, two cases of cns meningioma with metastasis to cervical lymph nodes are reported. the first case, a 48 year-old man developed cervical lymph node metastasis nine years after primary tumor diagnosis. the second case, a 23 year-ol...

Vitreoretinal surgery is challenging even for expert surgeons owing to the delicate target tissues and diminutive workspace in retina. In addition improved dexterity accuracy, robot assistance allows (partial) task automation. this work, we propose a strategy automate motion of light guide with respect surgical instrument. This automation instrument's shadow always be inside microscopic view, w...

Micro ribonucleic acids (miRNAs) are a cluster of small non-coding RNA molecules predicted to regulate more than 30% of coding messenger (m)RNAs in the human genome and proven to be essential in developmental and pathological processes. The miR-182 gene was first found to be abundantly expressed in sensory organs and regulates the development of the retina and inner ear. Further studies reveale...

A 60-year-old patient with testicular seminoma was referred for F-18 FDG PET/CT Study to evaluate recurrence. In addition to hypermetabolic cervical, mediastinal and hilar lymph node tumoral metastases, segmental intense FDG uptake along the lumbar spinal cord suggestive of tumoral metastasis was noted which quite an unusual presentation is.  At the time of PET study the patient was symptomless...
