He continued his studies of physiology in Vienna under Ernst Wilhelm von Br cke 1819 1892 , and in T bingen with Felix Hoppe Seyler 1825 1895 . From 1870 until 1907, Sertoli was a professor of anatomy and physiology at the Royal School of Veterinary Medicine in Milan , and after 1907 a professor of physiology. In Milan he founded the Laboratory of Experimental Physiology. Sertoli is remembered for his 1865 discovery of the eponymous Sertoli cell .

DiseasesDB ICD10 ICD9 ICDO OMIM MedlinePlus eMedicineSubj eMedicineTopic eMedicine mult MeshID Serous tumours are part of the surface epithelial stromal tumour group of Ovarian cancer ovarian neoplasm s. They are common neoplasm s with a strong tendency to bilaterality, and they account for 50 of all ovarian tumours. Sixty percent are benign , 10 are borderline and 30 are malignant . Explanation Benign serous tumours are unilocular have one lobe however if very large may be multilocular, contain clear fluid and have a smooth lining composed of columnar epithelial cell s with cilia . Surgery is curative. In borderline lesions, the cyst or surface is lined by papillary structures, which are often very complex. Surgery is usually curative. Microscope Microscopically , stromal papillae are covered by atypical epithelial cell s, but stromal invasion is absent, nuclear stratification is present. Malignant serous tumours are solid, may be cystic and often show haemorrhage and necrosis . They are lined by a complex papillary pattern with presence of nuclear anaplasia. Serous carcinomas often have bulky peritoneum peritoneal and omentum omental metastases , and spread to the lymph node s is frequent. Unsurprisingly, 5 year survival decreases as the stage increases. There is a 25 survival rate with a stage III serous carcinoma. Staging Stage I Tumour growth limited to ovaries. Stage II Growth involving one or both ovaries with pelvic extension. Stage III Tumour involving one or both ovaries with implants outside pelvis. Stage IV Tumour involving one or both ovaries with presence of distant metastasis.

Usually they are multiple but occasionally there can be a proliferating trichilemmal cyst which grows to a large size and ulcerates. These can resemble a squamous cell carcinoma both clinically and histologically and these ulcerating solitary cysts are called Cock s peculiar tumour.
