UNLABELLED Breast cancer, in India, is the second commonest cancer in females. Receptor status with ER/PR/Her 2 is now routinely done in patients with invasive carcinoma. The tumour suppressor gene, p53, is also present in most breast cancers. Proteins produced by a mutated p53 gene, accumulate in the nucleus of tumour cells and are detected by(More)
BACKGROUND Meningiomas are common slow-growing primary central nervous system tumors that arise from the meningothelial cells of the arachnoid and spinal cord. Human epidermal growth factor receptor 2 (HER2) or HER2/neu (also known as c-erbB2) is a 185-kD transmembrane glycoprotein with tyrosine kinase activity expressed in meningiomas and various other(More)
BACKGROUND Incidence of multiple primary cancers though uncommon, is being frequently reported now-a-days owing to better diagnostic techniques, the prolonged life span and the increased incidence of long-term survival of cancer patients. MATERIALS AND METHODS This is a retrospective study. Cases of multiple malignancies diagnosed histopathologically were(More)
BACKGROUND Solid pseudopapillary tumor of the pancreas (SPT) is a rare tumor of low malignant potential, mostly described in young women. MATERIALS AND METHODS In this retrospective study from January 2000 - December 2010, there were 50 pancreatic tumors. In this period, four SPTs were encountered, which were analyzed with respect to clinical, imaging,(More)
Melanoacanthoma is a rare lesion. Melanoacanthoma of external ear is still rarer. We present two cases of melanoacanthoma of external ear in adults which presented as pigmented growths and clinically were suspected as malignant lesions. Histopathology was diagnostic as it demonstrated the characteristic elevated lesion with abundant melanin pigment. No(More)
BACKGROUND Secondary central nervous system (CNS) tumors are common in Western countries, but in Indian literature, scant data are available. With the advent of newer imaging techniques, the confirmatory histopathological diagnosis has become comparatively easier. Hereby, we have analyzed our data from a single tertiary care center in south India. (More)
Wilms' tumor (nephroblastoma) is extremely rare in adults, skeletal metastasis being still rarer. The clinical course of adult Wilms' tumor is very aggressive. The present case is a rare blastemal predominant adult Wilms' tumor presenting with skeletal metastasis. We report a case of 19-year-old female presented with severe low backache and colicky left(More)
The myxoid variant of chondrosarcoma is usually seen in soft tissues where it is known as chordoid sarcoma or parachordoma. Rarely, it involves bone and when it does, cranial bones are the preferred location. This tumor is frequently amalgamated with the chondroid variant of chordoma, especially when the lesion occurs in the sphenoid bone/spheno-occipital(More)
We present a rare case of epithelioid hemangioendothelioma (EHE) in the nasal cavity of a 40-year-old Indian male who presented with history of intermittent epistaxis. The lesion was tested for a panel of immunohistochemical markers like vimentin, CD31, CD34, Factor VIII, vascular endothelial growth factor (VEGF) and Ki67. Immunohistochemically, the(More)
