What does the 4 th edition of the World Health Organization Classification of Head and Neck Tumors bring new about mucosal melanomas? The recently published 4 th Edition of the World Health Organization Classification of Head and Neck Tumors addresses the most relevant and updated aspects of tumor biology, including clinical presentation, histopathology, immunohistochemistry, and prognosis of head and neck tumors. The objective of the present study is to compare these updates to the 3 rd edition of that book with regard to mucosal melanomas and to highlight the potential factors that differ those tumors from cutaneous melanomas.

WHO classification of head and neck tumours

Medical classification dates back to the days of William Farr who is credited with the development of a nosology, which later served as the forerunner for the modern-day disease classification by ICD. The WHO system of classification is a time-honoured system that has prevailed from decades together and is under constant evolution. The classification of odontogenic tumours was first formulated by Pierre Paul Broca and has undergone several transformations over years. Though the earlier classifications and their modifications by several authors and even by the WHO appeared to be fitting for their time, the latest edition of WHO classification of odontogenic and maxillofacial bone tumours neither seems to be complete nor perfect, even at the present context. It is unfortunate that even with the advancement of molecular biology, the present WHO classification on Odontogenic and Maxillofacial bone tumours, fails to serve as a 'reference standard' in the true sense of the term.

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. Their inclusion was based on the distinctive structures and tumor types and their relevance to the differential diagnosis and management of patients with tumors at these regions, especially regarding HPV-associated squamous cell carcinoma for the oropharynx which bears profound epidemiologic and therapeutic consequences.

This time interval has brought several key changes to a broad variety of tumor types in the head and neck region to the point that the topic of envisioning future changes in the WHO was a focus of a North American Society of Head and Neck Pathology Companion Meeting, March 2, , in San Diego, California [ 1 — 6 ]. Thus, the 4th edition of the WHO blue book is a crystallization of many of these predicted changes, and a welcome update.

Но затем я сделал несколько тестов и обнаружил… - Он остановился, вдруг почувствовав себя не в своей тарелке.  - Я обнаружил, что кто-то обошел систему фильтров вручную. Эти слова были встречены полным молчанием. Лицо Стратмора из багрового стало пунцовым. Сомнений в том, кого именно обвиняет Чатрукьян, не .

Против вашего присутствия в моем кабинете. Я протестую против ваших инсинуаций в отношении моего заместителя, который якобы лжет. Я протестую… - У нас вирус, сэр. Моя интуиция подсказывает мне… - Что ж, ваша интуиция на сей раз вас обманула, мисс Милкен. В первый раз в жизни.

 - Тем более приходи. Мы успеем выспаться перед поездкой на север. Дэвид грустно вздохнул: - Потому-то я и звоню. Речь идет о нашей поездке.

 Ты должен это сделать! - потребовала она и, отвернувшись, начала что-то печатать на клавиатуре Большого Брата.  - Мне нужен список очередности работы на ТРАНСТЕКСТЕ. Если Стратмор обошел фильтры вручную, данный факт будет отражен в распечатке. - Какое отношение это имеет к директорскому кабинету.

Терминал пискнул. СЛЕДОПЫТ ЗАПУЩЕН Сьюзан знала, что пройдет несколько часов, прежде чем Следопыт вернется. Она проклинала Хейла, недоумевая, каким образом ему удалось заполучить ее персональный код и с чего это вдруг его заинтересовал ее Следопыт. Встав, Сьюзан решительно направилась подошла к терминалу Хейла.

Сирены захлебнулись, мониторы Третьего узла погасли. Тело Грега Хейла растворилось в темноте, и Сьюзан, инстинктивно поджав ноги, прикрылась пиджаком Стратмора.

Слушайте меня внимательно… ГЛАВА 112 - Надеюсь, вы знаете, что делаете, директор, - холодно сказал Джабба.  - Мы упускаем последнюю возможность вырубить питание. Фонтейн промолчал.

 Он говорит, что вручит победителю ключ. - Ключ. - В этом и заключается его замысел.

 Хорошо, - сказала Сьюзан, стараясь сосредоточиться, - я сотру весь накопитель Хейла. И все переформатирую. - Нет! - жестко парировал Стратмор.  - Не делай .

Если все сложится нормально, она скоро выяснит местонахождение Северной Дакоты, и Стратмор конфискует ключ. Тогда дело будет только за Дэвидом.
