Melanoma accounts for only 4% of malignant neoplasms of the skin, but is considered the most serious because it is highly deadly. Mutations in the MAPK (Ras-Raf-MEK-ERK) pathway is closely linked to the lack of control of cell proliferation. Especially in melanoma, this pathway has become a target for the development of oncogene-targeted therapies, such as the potent inhibitors of v-Raf murine sarcoma viral oncogene homolog B (BRAFi) and mitogen-activated protein kinase kinase (MEKi).

Malignant transformation of cells depends on accumulation of DNA damage. Over the past years we have learned that the T cell-based immune system frequently responds to the neoantigens that arise as a consequence of this DNA damage. Furthermore, recognition of neoantigens appears an important driver of the clinical activity of both T cell checkpoint blockade and adoptive T cell therapy as cancer immunotherapies. Read More

This review of challenging diagnostic issues concerning high-grade endometrial carcinomas is derived from the authors' review of the literature followed by discussions at the Endometrial Cancer Workshop sponsored by the International Society of Gynecological Pathologists in 2016. Recommendations presented are evidence-based, insofar as this is possible, given that the levels of evidence are weak or moderate due to small sample sizes and nonuniform diagnostic criteria used in many studies. High-grade endometrioid carcinomas include FIGO grade 3 endometrioid carcinomas, serous carcinomas, clear cell carcinomas, undifferentiated carcinomas, and carcinosarcomas. Read More

What We Already Know About This Topic: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Although dantrolene effectively treats malignant hyperthermia (MH), discrepant recommendations exist concerning dantrolene availability. Whereas Malignant Hyperthermia Association of the United States guidelines state dantrolene must be available within 10 min of the decision to treat MH wherever volatile anesthetics or succinylcholine are administered, a Society for Ambulatory Anesthesia protocol permits Class B ambulatory facilities to stock succinylcholine for airway rescue without dantrolene. The authors investigated (1) succinylcholine use rates, including for airway rescue, in anesthetizing/sedating locations; (2) whether succinylcholine without volatile anesthetics triggers MH warranting dantrolene; and (3) the relationship between dantrolene administration and MH morbidity/mortality.

Total laryngectomy is a common method for the treatment of malignant tumors of the pharynx and larynx in China, but pharyngocutaneous fistula often happens after surgery, which burdens patients and affects postoperative recovery. At present, there are many measures to prevent pharyngocutaneous fistula, including strengthening nutrition pre-operative and post-operative, testing related indicators, controlling comorbidities, rational use of drugs, regular oral care, optimal selection of incision closure, and using of flaps and special materials during operation, etc. However, the choice of specific program needs to take care of the patient's condition, surgeon's skills and hospital conditions, and often requires multiple programs to be used together throughout the perioperative period.

Islet autotransplantation is particularly attractive to prevent diabetes after extended pancreatectomy for benign or borderline/malignant pancreas disease. Between 2008 and 2018, 25 patients underwent left extended pancreatectomy (>60%) and islet autotransplantation for neoplasm located in the pancreatic neck or proximal body. Overall, disease-free and diabetes-free survivals were estimated and compared with those observed in 68 non diabetic patients who underwent distal pancreatectomy for pancreatic neoplasms without islet autotransplantation.

Background: Biomarkers that could predict malignant transformation of recurrent respiratory papillomatosis (RRP) would be useful in patient follow-up. We investigated whether serum matrix metalloproteinase 8 (MMP-8) and tissue inhibitor of metalloproteinase 1 (TIMP-1) could predict malignant transformation of RRP and whether they associate with survival in laryngeal squamous cell carcinoma (LSCC) without preexisting RRP.

Methods: We analyzed serum MMP-8 (S-MMP-8) and serum TIMP-1 (s-TIMP-1) in 114 patients: 55 were treated for RRP and 59 for LSCC without preexisting RRP. Read More

For the radiologist performing body MRI, chemical shift imaging is a unique tool available to investigate the cellular composition of tissue. By leveraging the inherent difference in resonant frequency between water and fat protons that is due to their local chemical environment, chemical shift image acquisition can be timed to image water and fat protons when their collective signals are in phase or out of phase, to determine the relative amount of fat signal and water signal within an individual voxel. Loss of signal intensity between the in-phase and opposed-phase MR images indicates intravoxel lipid and can be used to make definitive benign diagnoses, characterize the tissue composition of solid organs, and serve as an adjunct imaging feature aiding in the diagnosis of a variety of benign and malignant processes in the chest and abdomen.

A 78-year-old woman presented with leg edema and exertional dyspnea. Echocardiography revealed a smooth-surfaced mass adjacent to the left atrium in the pericardial cavity with a massive pericardial effusion. Pericardiocentesis resulted in the drainage of a bloody effusion. Read More

Undifferentiated pleomorphic sarcoma (UPS), previously known as malignant fibrous histiocytoma, is a neoplasm that occurs most often in the extremities, trunk, and retroperitoneum. Rarely, UPS can occur in the cardiac chambers and great vessels. The diagnosis of UPS is difficult to establish with noninvasive imaging techniques, and these tumors may be mistaken for benign neoplasms preoperatively. Read More

A 47-year-old male was admitted to hospital for severe pericardial effusion; he had undergone surgical removal of cutaneous melanoma 10 years before. Echocardiography-guided pericardiocentesis revealed the presence of intramyocardial masses, which were better defined and characterized, together with pericardial involvement, by cardiac magnetic resonance. Pericardial fluid drained was negative for malignant cells, so video-assisted thoracoscopy was performed and pathologic tissue was biopsied, leading to the diagnosis of metastatic melanoma.

The histopathological differentiation of melanocytic nevi from malignant melanoma (MM) is based on well-known criteria, and is straightforward in the vast majority of cases. However, there are few cases of melanocytic lesions (ML), the diagnosis of which is very challenging or even impossible. Here we have studied several morphological characteristics with particular focus on elastic fibers (EF) to identify features, helpful for the distinction between nevi and MM. Read More
