Cutaneous Adnexal Cysts Revisited: What We Know and What We Think We Know
Cutaneous cysts have been classified by dermatopathologists in many different ways. Here, we propose a novel classification of cutaneous adnexal cysts according to their origin in the folliculosebaceous unit and the sweat glands. By examining the lining of the cystic structure, its origin can be easily identified. Epidermal cysts have an epithelial wall containing a granular layer with lamellar keratinization, indicating an infundibular origin. Tricholemmal cysts have an undulating epithelial wall with no granular layer and a compact keratinization, showing an isthmic origin. In steatocystoma, dermoid cyst, and folliculosebaceous hamartoma, the epithelial lining shows a crenulated appearance which is seen in the sebaceous duct. Hidrocystoma shows the characteristic cuboidal epithelial lining of sweat glands with decapitation secretion in its apocrine forms. The hair matrix cyst wall is composed of basaloid cells maturing to squamoid cells, as seen in the normal hair matrix and shadow cells in the lumen. Metabolizing acquired dioxin-induced skin hamartoma (MADISH) is a cystic lesion with lamellar keratinization, and no sebaceous glands. The classification proposed here aims to simplify the complexity of cutaneous adnexal cysts, and to facilitate a better understanding of the origin of cystic lesions of the skin.Dermatopathology 2018;5:79 –85

Authors: Schöll N, Rohde GGU Abstract Pneumonia belongs to the most frequent and most deadly infectious diseases worldwide. It represents an increasing problem for the aging population. The incidence and mortality rises with every decade. The clinical presentation of pneumonia differs between elderly and younger patients. Multiple factors including functional status (self-dependency and immobilization), comorbidities, immunosenescence, nutritional status, swallowing disorders have to be accounted for. Pneumonia in the elderly has to be differentiated from nursing home acquired pneumonia. Diagnosis of pneumonia...

Authors: Raspe M, Rolling T, Leisse C, Fischer J, Lehmann C Abstract Infectious Diseases are a cross-sectional area connected to various medical disciplines and offer interested physicians multiple working opportunities. The spectrum of infectious diseases covers both out- and inpatient care as well as basic, clinical and epidemiological research. The need for infectious diseases specialists is increasing, thus career prospects are promising. Working conditions in infectious diseases are comparatively family-friendly. With this article we intend to arouse interest for working in the fascinating fields of infectious...
