Papillary Microcarcinoma of the Thyroid

摘要: Papillary thyroid carcinoma is the most common type of differentiated [1]. The majority these lesions are small [2]; those whose diameters measure £1 cm have been designated by World Health Organization as papillary microcarcinoma (PMCT) [3]. In older literature, they were frequently referred to occult cancers since first discovered at autopsy; others, now usually incidentalomas, identified in operative specimens submitted for nonmalignant diseases [4]. One conclusion drawn from discoveries that PMCT seldom constitutes a clinically significant problem [5] and, therefore, may not require therapeutic response. group [6] has even proposed solitary be renamed “papillary microtumor” reflect its benignity and eliminate emotionally charged diagnosis cancer [6]. Today, many PMCTs no longer or incidental, but life prior head neck surgery [7]. This change results expanded use high resolution imaging [8] expanding application ultrasound-guided fine-needle aspiration biopsy (FNAB) eventing nodules [9]. Despite fact all without complications [10], prognosis remains excellent, disease fatal. Because this, there consensus concerning management PMCT. Controversy persists regarding extent appropriate intervention whether any necessary beyond follow-up. A review literature suggests, however, reasonable guidelines can developed aid decisionmaking. this chapter, we will term incidental refer found autopsy an specimen removed other than known malignancy. Non-incidental diagnosed palpation another technique such ultrasound (US) intervention. Occult unsuspected history physical examination exist because some distant manifestation, metastasis.
