Question: At what age was the Countess von Gelichen's brother when he inherited his cousin's Marquesstate of Hertford in 1870? Passage:When the Countess von Gleichen's brother, Francis, inherited his cousin's Marquessate of Hertford in 1870, the Queen granted her the rank and style of the daughter of a marquess by Royal Warrant of Precedence, entitling her to prefix Lady to her name. However, she continued to use her comital title until 15 December 1885, when it was gazetted in the Court Circular that the Queen had granted her permission to share, within the British Empire, her husband's princely title. Henceforth she was known as HSH Princess Victor of Hohenlohe-Langenburg, although this changed neither her legal rank nor her title in the German Empire. In accordance with the original Coburg grant, her children were also Count/Countess von Gleichen and, although granted unique precedence before the daughters and younger sons of English dukes in 1913, they never received authorisation to share their parents' princely style at the Court of St. James's, and were known by their comital title (dropping, however, the von) until George V Anglicised their style in 1917, along with the styles of members of his own family who bore German titles. Princess Victor did not live to undergo that demotion in titulature.

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.
