An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic; surgical excision (thyroidectomy), radioiodine therapy, or both may be used. [33]
The thyroid ultrasound is also very effective to discover microcarcinomas, which refer to very small carcinomas (<1 cm). Papillary thyroid carcinomas are also discovered when a hard nodule is found in multinodular goiter, when enlarged cervical lymph nodes are detected, or when there are unidentified metastatic lesions elsewhere in the body.

[10] [14] Up to 65% of adults have small nodules in their thyroids, but typically under 10% of these nodules are found to be cancerous. [15] Sometimes, the first sign is an enlarged lymph node. Later symptoms that can be present are pain in the anterior region of the neck and changes in voice due to an involvement of the recurrent laryngeal nerve .
In medicine, nodules are small firm lumps, usually greater than 1 cm in diameter. [1] [2] If filled with fluid they are referred to as cysts. [2] Smaller (less than 0.5 cm) raised soft tissue bumps may be termed papules. [3] The evaluation of a skin nodule includes a description of its appearance, its location, how it feels to touch and any ...
Histopathology of IPMN types in a distal pancreatectomy specimen from a 60-year-old man, by gross pathology (center image), microscopy and immunohistochemistry: The resected specimen (c) revealed that the mural nodule in the MPD consisted of PB-type IPMN with high-grade dysplasia (adenocarcinoma) (a) with a diffuse positivity of p53 immunostaining (an insert) and KRAS mutation (G12V).

Glucagon-like peptide 1 (GLP-1) receptor agonists, which are used to treat type 2 diabetes and/or obesity, were linked to vision problems in a small study at the University of British Columbia.
Thyroid follicular adenoma ranges in diameter from 3 cm on an average, but sometimes is larger (up to 10 cm) or smaller. The typical thyroid adenoma is solitary, spherical and encapsulated lesion that is well demarcated from the surrounding parenchyma. The color ranges from gray-white to red-brown, depending upon the cellularity of the adenoma
