This malignancy is an important public health problem worldwide with more than new cases diagnosed each year. Patients often present with advanced stage disease and despite combined therapy outcome remains poor.

Etiology The major risk factor for head and neck cancer is chronic exposure of epithelia to tobacco smoke and alcohol.

WHO classification of head and neck tumours

In this editorial, we provide a broad review of the consequential modifications in the newly released 4th edition of the WHO head and neck tumor classification, comment on two selected reviews in this volume of the journal, and succinctly discuss the changes made in the salivary gland tumor chapter [ 1 , 2 , 3 ]. In general, the new edition represents a streamlined and simplified version from previous editions in an effort to reduce redundancy and to maintain consistency within and between different chapters and topics [ 4 ]. This task has been achieved through presenting tumor entities to the sites of their most common occurrence and presentation. Sometimes, however, exceptions to this rule have been made in limited entities for either prominence or their relevance to diagnosis and differential diagnosis at certain sites. For the first time in this edition, chapters devoted to the oropharyngeal and the neck region were established.

Updated WHO nomenclature of head and neck lesions and associated imaging findings

The salivary gland section in the 4th edition of the World Health Organization classification of head and neck tumors features the description and inclusion of several entities, the most significant of which is represented by mammary analogue secretory carcinoma. This entity was extracted mainly from acinic cell carcinoma based on recapitulation of breast secretory carcinoma and a shared ETV6-NTRK3 gene fusion. Also new is the subsection of "Other epithelial lesions," for which key entities include sclerosing polycystic adenosis and intercalated duct hyperplasia.

 Потрясающе, - страдальчески сказал директор.  - У вас, часом, нет такой же под рукой. - Не в этом дело! - воскликнула Сьюзан, внезапно оживившись. Это как раз было ее специальностью.  - Дело в том, что это и есть ключ. Энсей Танкадо дразнит нас, заставляя искать ключ в считанные минуты.

Стояла полная тишина, и он внимательно прислушался. Ничего. Вроде бы на нижней ступеньке никого .

 Как прикажете это понимать. На лице Стратмора тут же появилось виноватое выражение. Он улыбнулся, стараясь ее успокоить.

 Тебе следовало бы работать в полиции, - улыбнулся Стратмор.  - Идея неплохая, но на каждое послание Танкадо, увы, поступает ответ. Танкадо пишет, его партнер отвечает. - Убедительно.  - Сьюзан нахмурилась.
