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: When was the team founded that paid 1,000 pounds to sign Charles in 1935? Passage:Prior to taking up speedway, Charles worked as a baker and grocer, and performed in music halls with a piano accordion. In 1929 Charles rode for Burnley, in 1930 for Manchester White City and then for Leeds Lions and Belle Vue in 1931 but was badly injured and lost his form, and so retired from the sport. In 1933, the Belle Vue Aces tempted him out of retirement, and looked to have regained his former form when he won the Wembley championship that year, also breaking the track record. In 1934 Charles' father died, so he returned to the family business. In 1935 Wembley Lions paid £1,000 to sign Charles, where he became the club's top scorer and was selected to ride for England against Australia. He went on to win the Star Riders' Championship despite only initially taking part in the competition as a replacement for Ginger Lees. In 1936 he topped the club's scoring again, was top scorer for the England Test team, and qualified for World Championship final, tying for fourth place with Cordy Milne, and broke the track record during the meeting. He qualified again for the 1937 final. At the end of the 1938 season he decided to retire to concentrate on his long-term hobby of gliding.

Q: Question: How old was Charlemagne's son when he destroyed the Ring of the Avars? Passage:Since about 560, the Avars had ruled over large parts of the Pannonian Basin and Carantania southeast of Francia, though in the last decades, the Avar Khaganate had to deal with Bulgarian and Croat incursions. To secure the frontier of his empire and the traffic on the trade routes to the east, Charlemagne allied with Khan Krum of Bulgaria and the Croatian duke Vojnomir, and from 791 launched several campaigns against the Avars, where he, according to the Vita Karoli Magni, encountered only modest opposition. In 796 Carolingian forces under Charlemagne's son Pepin of Italy destroyed the main Avar fortress called the Ring of the Avars and made the Khagan a Frankish vassal, while the remaining Avars retreated behind the Tisza River. The victory is perpetuated by the poem De Pippini regis Victoria Avarica.
