Benchmark data set for breast cancer associated genes.

Breast cancer is one of the leading causes of death in women worldwide. The main reason could be inheritance, change in environmental conditions or the mutation in certain genes that cause cancer. These genes are not negligible, on the contrary, a wide range of genes have their involvement in the development and progression of different stages of breast cancer.

Inexplicable Co- Existence of Eccrine Spiradenoma and Lichen Planus in an old Case of Basal Cell Carcinoma.

Eccrine spiradenoma is a rare benign adnexal tumour usually seen in the head, neck or upper trunk in young adults. It is rare in the lower extremities and in the elderly. Co- existence of eccrine spiradenoma with other lesions like cylindroma, trichoepithelioma, hidradenoma and chondroid syringoma has been documented in literature.

Benign triton tumour of upper lip- a rare neoplasm at an extremely uncommon site.

Benign Triton tumours are exceedingly rare tumours occurring predominantly in young children. Fewer than 20 cases have been reported in literature. The tumours develop as masses in various large nerve trunks, the most common of them being the brachial and the sciatic.

Extra- adrenal silent retroperitoneal paraganglioma: report of a rare case.

Extra- adrenal retroperitoneal paragangliomas are extremely rare neuroendocrine neoplasms with an incidence of 2-8 per million. They arise from embryonic neural crest cells and are composed mainly of chromaffin cells located in the para- aortic sympathetic chain. They synthesize, store and secrete catecholamines because of which they may present with headache, sweating, palpitation and symptoms of hypertension.

Cystic endosalpingiosis of uterine parametrium- a scarcely encountered and sparsely documented entity.

"Endosalpingiosis" refers to the presence of fallopian tube-like epithelium outside fallopian tubes. It merits attention both by Clinicians and Pathologists since it is a benign, non- neoplastic condition which maybe easily misjudged as carcinoma mainly due to the rarity of its occurrence and lack of awareness owing to paucity of its documentation in literature. Further, salpingiosis can undergo massive cystic change thereby mimicking a tumour when it is referred to as cystic salpingiosis.
