Endometrial Carcinoma
Clinical HistoryA 63-year old woman presented with a history of dull lower abdominal pain for 2 months and heavy persistent vaginal bleeding for 1 week. The menopause had occurred 13 years previously. Radical abdominal hysterectomy and bilateral salpingo-oophorectomy were commonly performed for the treatment of endometrial cancer following confirmation of endometrial carcinoma in biopsy.PathologyThe specimen consists of uterus, fallopian tubes and ovaries. The endometrial cavity and endocervical canal have been opened on the anterior aspect. The endometrial lining is grossly abnormal especially on the right side and a brown polypoid tumour has invaded the myometrium and extends inferiorly into the cervical canal. Histologically this was a well-differentiated adenocarcinoma of the endometrium. The left ovary, which has been sectioned in the coronal plane, is enlarged and has several large follicular cysts/cavities.Further InformationEndometrial carcinoma is the most common gynecological malignancy in developed countries and the second most common in developing countries after cervical cancer. There are two major types of endometrial carcinoma. Endometroid carcinoma account for almost 80% of endometrial carcinoma. They usually present early and so have a more favourable outcome. These tumours may arise from atypical endometrial hyperplasia. Common genetic abnormalities seen in endometrioid tumours are mutations in the PTEN, PIK3Ca and ARID1A genes. Serous carcinoma are a less common form of endometrial carcinoma. These tumours are associated with mutations in TP53 gene and carry a poorer prognosis. Endometrioid tumours tend to affect women aged 55 to 65 years. Risk factors for developing endometrioid endometrial cancer include obesity, impaired glucose tolerance, infertility, unopposed estrogen therapy (e.g. early menarche, late menopause or exogenous sources). Serous neoplasms affect older women aged 65 to 75 years with other risk factors for development include having a lower BMI and an atrophic uterus. Women with Hereditary Nonpolyposis Colorectal Cancer (Lynch Syndrome) have a significantly higher risk of developing endometrial cancer.The most common symptom of endometrial cancer is abnormal vaginal bleeding. Most frequently it presents as post-menopausal bleeding, which often allows early presentation. Others may be asymptomatic or an incidental finding of an abnormal endometrium on abdominopelvic imaging. The main radiological sign of endometrial cancer is abnormally thickened endometrium on pelvic ultrasound or CT scan. Diagnosis is made on endometrial biopsy, endometrial curettage or hysterectomy. Treatment depends on the stage of the cancer and includes local radiotherapy, systemic chemotherapy and surgical hysterectomy +/- salpingo-oophorectomy.

Osteochondroma
Clinical HistoryA 61-year old male with prostate cancer attends pre-assessment clinic prior to a prostatectomy. Overall, he feels well with no major complaints. On review of symptoms, it is noted he has chronic pain in his right knee, which his GP called osteoarthritis. To exclude boney metastases of the prostate carcinoma, a knee x-ray is ordered, which shows a pedunculated lesion projecting from the medial aspect of the diaphysis of the right femur. His prostatectomy goes ahead but he subsequently dies from a postoperative pulmonary embolism.Pathology The specimen is the lower end of the patient’s right femur, which has been cut in the coronal plane and mounted to display the external surfaces. A pedunculated bony protuberance 2 cm in length projects from the medial aspect of the femoral shaft 7 cm above the medial condyle. The projection is composed of normal bone with a thin cap of hyaline cartilage at the tip. This is an example of an osteochondroma.Further InformationAn osteochondroma (or an exostosis) is a benign cartilaginous tumour. They are comprised of a cartilaginous capped bony protrusion from the external surface of the bone from which they arise. They are the most common benign bone tumours. Most osteochondromas occur spontaneously but they may also occur as part of multiple hereditary exostosis syndrome or post radiotherapy. They usually develop from or near the growth plate. They most commonly arise from the appendicular skeleton, especially in the lower limb around the knee or the upper limb at the proximal humerus. Men are more commonly affected than women.Symptoms vary on the site and size of the growth. Many osteochondroma remain asymptomatic. Osteochondroma lead to symptoms from the compression of surrounding neurovascular structures. They may also cause a pain from myositis or a fracture of the bony spur. They usually present in the second decade of life. They can be diagnosed with plain x-ray but MRI is the gold standard to ensure that there is no malignancy present within the growth.Hereditary exostoses are associated with mutations in the EXT1 and EXT2 genes. Reduced expression of these genes has also been seen in sporadic osteochondromas. Osteochondromas stop forming as fusion of the growth plate occurs. Treatment of excision is only if symptoms are severe. Malignant transformation to chondrosarcoma is rare in sporadic cases but more common in hereditary exostosis (5-20%).

Lung - Staphylococcus aureus Abscesses
Clinical HistoryA 55-year old female presents with severe dyspnoea, a productive cough and oral candidiasis. She is immunosuppressed with a history of rheumatoid arthritis being treated with steroids and cyclophosphamide. Sputum cultures grew staphylococcus aureus. She was commenced on appropriate therapy but died shortly after admission.Pathology The right lung has been bisected. There are multiple irregular abscess cavities visible. The largest of these, in the apex of the lower lobe, measures 4 x 3 cm in diameter. At the apex of the upper lobe, there is another irregular abscess cavity which is less obvious, approximately 3 x 2 cm in diameter surrounded by a zone of consolidation. A number of small abscesses are also seen. Patchy consolidation is present in the middle lobe. Numerous bronchi contain and are obstructed by plugs of pus. Cultures taken from the specimen grew Staph. aureus. This is an example of multiple Staphylococcal lung abscesses in an immunosuppressed patient.Further InformationStaphylococcus aureus is a gram-positive coccus. It is part of the microbiota of the human body usually found on the skin or upper respiratory tract. It is usually commensal but may cause opportunistic infections such as skin infections commonly or less frequently, pneumonia and endocarditis. It can cause both community and hospital-acquired pneumonia. Hospital-acquired Staph pneumonia is most commonly associated with intubation and prolonged admissions. Prevalence of hospital acquired pneumonia caused by Methicillin-Resistant Staph Aureus (MRSA) is increasing.It is an important cause of secondary bacterial pneumonia in patients following viral respiratory infection e.g. post influenza infection. Intravenous drug users have an increased risk of developing ‘metastatic’ Staph. aureus pneumonia and endocarditis, as a result of staph bacteraemia caused by the use of dirty needles. Staph. aureus pneumonia is severe and associated with an increased rate of complications, such as ca vitating abscess formation and empyema.Staph Aureus pneumonia should be suspected in any of the high-risk groups above as well as patients with pneumonia with rapid deterioration, haemoptysis, early multilobar pneumonia on X-ray, pulmonary cavitation or disseminated intravascular coagulation. First line treatment for Staph. aureus pneumonia is penicillin antibiotics, such as flucloxacillin. Staph aureus resistance to penicillin is very common with penicillinase production e.g MRSA. MRSA is treated with glycopeptide antibiotics, such as vancomycin, or oxazolidinone antibiotics, such as linezolid.

Metastatic melanoma
Clinical HistoryIn the 1970s, a 31-year-old woman presented with severe headache and diplopia on a background of having a pigmented skin lesion (diagnosed as an invasive skin melanoma) removed from her neck 8 months earlier. Clinical examination revealed no abnormality, and following discharge the patient was later re-admitted with persistent vomiting. Her condition deteriorated and she died.PathologyThis specimen demonstrates widespread intracerebral melanoma metastases. The inferior surface is characterised by many elevated dark nodules up to 1.5 cm in diameter. Similar lesions are present on the cut superior surface where it is seen that these secondary melanotic deposits are confined exclusively to the grey matter. The tumour deposits are not encapsulated and are invading the cortex. Some necrosis and haemorrhage is present.Further informationOf all patients who have metastatic disease to the brain, 10% are from skin melanoma. Risk increases with age over 60 years, male gender, disease duration and more advanced tumour/metastatic stage. BRAF and NRAS mutations, expression of CCR4 receptors on tumour cells, and activation of the PI3K pathway are all risk factors for the development of cerebral metastasis. 80% of melanoma brain metastases are supratentorial. Presentation is often with headache, neurologic deficits and/or seizures. Furthermore, these lesions are at risk of spontaneous haemorrhage. Modern diagnosis is based on neuroimaging and often histology of a stereotactic brain biopsy, if no previous diagnosis has been made. Treatment includes stereotactic radiosurgery (SRS), radiotherapy and/or systemic therapy with “checkpoint inhibitor immunotherapy” or targeted treatments. This has improved median survival upto 11 months in recent years.
