Question: Who was the other finalist in the 1930 Allan Cup other than the team Roche was on? Passage:Roche was born in Prescott, Ontario, but moved to Montreal where he played junior hockey for the Montreal Victorias and other teams. He moved up to senior hockey for the Montreal Hockey Club and played for their Allan Cup-winning squad of 1930. He signed with the Maroons of the NHL, playing for the Maroons and the Windsor Bulldogs until 1933. He was released by the Maroons and signed with the Bruins in January 1933 only to be traded to the Senators one month later. In his one full season with the Senators in 1933–34 he showed a scoring touch, scoring 13 goals and 16 assists in 45 games. The next season, the Senators relocated to St. Louis to become the Eagles. Roche was traded twice in 1934–35; from St. Louis to Buffalo, then to the Red Wings. That marked his last season in the NHL, as he subsequently played for various minor-league pro teams until 1942.

Question: On what date was the person who sent an emissary rather than attend the 1931 meeting with Luciano and three others in person born? Passage:In April 1931, Salvatore Maranzano, head of the Castellammarese clan in New York City, declared himself capo di tutti capo (boss of all bosses). Lucky Luciano, who opposed Maranzano's claim to control the Luciano crime family, decided to have Maranzano murdered. On April 21, 1931, he met in Cleveland with Frank Milano, Moe Dalitz, Meyer Lansky, Santo Trafficante Sr., and an emissary sent by Al Capone. The five agreed with Luciano's plan to kill Maranzano and establish a new federation of crime families to handle disputes. After the September 10, 1931, assassination of Maranzano, the title of capo di tutti capo was retired and "The Commission" established by the American Mafia. Milano was named a member of The Commission, alongside Joseph Bonanno, Al Capone, Tommy Gagliano, Lucky Luciano, Vincent Mangano, and Joe Profaci.

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.
