Germline and mosaic mutations causing pituitary tumours: genetic and molecular aspects.

J Endocrinol 2019 Feb;240(2):R21-R45

Centre for Endocrinology, William Harvey Research Institute, Barts and the London School of Medicine, Queen Mary University of London, London, UK.

While 95% of pituitary adenomas arise sporadically without a known inheritable predisposing mutation, in about 5% of the cases they can arise in a familial setting, either isolated (familial isolated pituitary adenoma or FIPA) or as part of a syndrome. FIPA is caused, in 15-30% of all kindreds, by inactivating mutations in the AIP gene, encoding a co-chaperone with a vast array of interacting partners and causing most commonly growth hormone excess. While the mechanisms linking AIP with pituitary tumorigenesis have not been fully understood, they are likely to involve several pathways, including the cAMP-dependent protein kinase A pathway via defective G inhibitory protein signalling or altered interaction with phosphodiesterases.

Cancer Treat Rev 2018 Dec 1;72:56-64. Epub 2018 Dec 1.

Radiation Oncology Department, Centre François Baclesse, Caen, France; Archade, Advanced Resource Center for Hadrontherapy in Europe, Caen, France; Normandy University, Université de Caen Basse Normandie, Caen, France; Laboratoire de Physique Corpusculaire, Caen, France.

Introduction: The depth-dose distribution of a proton beam, materialized by the Bragg peak makes it an attractive radiation modality as it reduces exposure of healthy tissues to radiations, compared with photon therapy Prominent indications, based on a long-standing experience are: intraocular melanomas, low-grade skull-base and spinal canal malignancies. However, many others potential indications are under investigations such as the benign morbid conditions that are compatible with an extended life-expectancy: low grade meningiomas, paragangliomas, pituitary adenomas, neurinomas craniopharyngioma or recurrent pleomorphic adenomas.

Materials: Given the radiation-induced risk of secondary cancer and the potential neurocognitive and functional alteration with photonic radiotherapy, we systematically analyzed the existing clinical literature about the use of proton therapy as an irradiation modality for cervical or intracranial benign tumors.

Department of Oral & ENT Pathology, Pitié-Salpêtrière Hospital, Department of Dermatology, Cochin-Port Royal Hospital, Paris France.

Introduction: Pleomorphic adenoma (PA) is the most common benign salivary gland tumor, frequently affecting the major salivary glands but also the palatal or labial minor salivary glands. Pleomorphic adenomas affecting the retromolar trigone have seldom been reported with only few cases described in the literature.

Observation: We present the case of a young female patient who presented with this rare localization of pleomorphic adenoma and its subsequent management. Read More

Systematic review of cure and recurrence rates following minimally invasive parathyroidectomy.

BJS Open 2018 Dec 28;2(6):364-370. Epub 2018 May 28.

Department of Ear, Nose and Throat, Head and Neck Surgery St George's Hospital London UK.

Background: The majority of patients with primary hyperparathyroidism (PHPT) have a single overactive adenoma. Advances in preoperative imaging and surgical adjuncts have given rise to minimally invasive parathyroidectomy (MIP), with lower complication rates in comparison with bilateral neck exploration. Misdiagnosis and undertreatment of multiglandular disease, leading to potentially higher recurrence rates, remains a concern. Read More

Solitary rectal ulcer syndrome complicating sessile serrated adenoma/polyps: A case report and review of literature.

World J Clin Cases 2018 Nov;6(14):820-824

Department of Pathology, Fudan University Shanghai Cancer Center, Shanghai 200032, China.

Solitary rectal ulcer syndrome (SRUS) is a rare benign condition, which can mimic many other diseases because of their similarities in clinical, endoscopic and histological features. Sessile serrated adenoma/polyp (SSA/p) is a premalignant lesion in the colon and rectum. The misdiagnosis of SSA/p in SRUS patients has been noted, but the case of SRUS arising secondarily to SSA/p has been rarely reported. Read More

Diagnosis of an extremely rare pleomorphic adenoma of the breast with core needle biopsy: A case report.

Ann Med Surg (Lond) 2018 Dec 5;36:242-245. Epub 2018 Nov 5.

Takahashi Breast and Gastroenterology Clinic, Yamazaki Seiren Bldg. 2F, 6-2-22, Uehonmachi, Tennoji-Ku, 543-0001, Osaka, Japan.

Introduction: Pleomorphic adenoma (PA) rarely originates in the mammary gland. This tumor is a benign mixed tumor and is commonly found in the salivary glands, but rarely shows findings similar to those of breast cancer. The tumor is misdiagnosed in 30-50% of the patients, including overdiagnosis of malignancy preoperatively, leading to unnecessary surgery for breast cancer. Read More

Rates of colorectal cancer detection in screening colonoscopy post appendicectomy in patients 50 years and over.

Ann Med Surg (Lond) 2018 Dec 20;36:239-241. Epub 2018 Nov 20.

Caboolture Hospital, 120 McKean Street, 4510, Queensland, Australia.

Introduction: Acute appendicitis in older adults is relatively uncommon and could be the first presentation of an underlying colorectal carcinoma. Colonoscopy in these individuals affords the opportunity for earlier diagnosis and treatment. The finding of increased rates of colorectal cancer (CRC) with older patients who have had appendicitis was supported by a number of small studies and case reports in the early 1980s. Read More
