[Q]: Question: Which part of the body can lymph nodes be found in? Passage:Diagnosis of MCC begins with a clinical examination of the skin and lymph nodes. Following, definitive diagnosis of Merkel cell carcinoma (MCC) requires examination of biopsy tissue to identify its histopathologic features. An ideal biopsy specimen is either a punch biopsy or a full-thickness incisional biopsy of the skin including full-thickness dermis and subcutaneous fat. On light microscopy, MCC shows basaloid tumor nests with neuroendocrine features ("salt and pepper" chromatin, scarce cytoplasm, and brisk mitotic activity). In addition to standard examination under light microscopy, immunohistochemistry (IHC) is also generally required to differentiate MCC from other morphologically similar tumors such as small cell lung cancer, the small cell variant of melanoma, various cutaneous leukemic/lymphoid neoplasms, and Ewing's sarcoma. Similarly, most experts recommend longitudinal imaging of the chest, typically a CT scan, to rule out that the possibility that the skin lesion is a skin metastasis of an underlying small cell carcinoma of the lung. Once an MCC diagnosis is made, a sentinel lymph node biopsy is recommended as a part of the staging work-up needed to determine prognosis and subsequent treatment options.

[Q]: Question: How old was Frank Bush the year he was fired? Passage:The Texans responded to the 2010 poor defensive showing by firing defensive coordinator Frank Bush, secondary coach David Gibbs, linebackers coach Johnny Holland, and assistant linebackers coach Robert Saleh. Kubiak, a ball boy for beloved former Houston Oilers head coach O.A. "Bum" Phillips in the 1970s, hired long-time friend, and Bum's son, Wade Phillips to take over as the Texans' new defensive coordinator on January 5, 2011. Phillips became available after being fired as head coach of the Dallas Cowboys halfway through the 2010 season. Phillips was allowed to bring in his own assistant coaches. The Texans signed two high-profile free agent defensive backs, Johnathan Joseph and Danieal Manning, and used their first five draft picks, including two in the second round of the 2011 NFL Draft, on more defensive players.
