IS IT THIS? - reference only, to read alongside your own examination
  SYMPTOMS - what the patient reports (2)
    - Most nodules cause no symptoms and are found incidentally on imaging done for other reasons
    - Neck pressure or pain can occur, especially with sudden bleeding into the nodule  [bleeding]
  SIGNS - what you find (4)
    - A palpable lump in the front of the neck is the classic presenting finding  [skin nodule]
    - Nodules over 4 cm carry roughly a 19% risk of malignancy
    - Firmness, fixation to surrounding tissue, and enlarged neck nodes raise malignancy concern
    - A solitary nodule with neck nodes over 1 cm and vocal cord paralysis together are almost
      always malignant  [vocal cord paralysis]
  TESTS (6)
    - TSH is checked first in every patient with a thyroid nodule
    - A normal or high TSH raises malignancy concern, while a low TSH usually favors a benign nodule
    - Ultrasound can find lesions as small as 2 mm and helps tell benign from malignant nodules
    - Microcalcifications, irregular margins, poor echogenicity, a taller-than-wide shape, or extra
      blood flow suggest cancer on ultrasound
    - Ultrasound-guided fine-needle aspiration is preferred over palpation-guided sampling
    - Cystic or spongiform nodules are low risk and only sampled once over 2 cm
  IF NOT THIS - what else fits (4)
    - A congenital neck mass, usually noticed at birth but sometimes only in adulthood
    - Cancer of the tongue, tonsil, or thyroid can present as a cystic neck mass
    - Inflammatory masses are usually enlarged viral or bacterial lymph nodes near the
      sternocleidomastoid muscle
    - A metastatic neck mass from elsewhere is usually squamous cell carcinoma of the aerodigestive
      tract

1. NO DRUG THERAPY IN PRIMARY CARE (REFERRAL & ADVICE)    [1st line]
   Adult    Thyroid nodules are a common finding in Egyptian primary care; the GP recognises and
            refers for ultrasound and biopsy to exclude malignancy. - Refer, with advice
   Peds     Children follow the same pathway: recognise and refer. No primary-care medicine is
            implied.
   Source   No dose - referral pathway, no medicine given in primary care
   Why      Thyroid nodules are a common finding in Egyptian primary care; the GP recognises and
            refers for ultrasound and biopsy to exclude malignancy.
   Caution  RED FLAG - History of neck irradiation in childhood: assess urgently and refer.
            Features suggesting malignancy (rapid growth, hardness, fixation, lymph node swelling)
            change management from benign follow-up to urgent cancer work-up referral.
            No medicine is prescribed for this in primary care - this entry is for recognition and
            referral. Anything given is decided by the service it is referred to.
            RED FLAG - Nodules larger than 4 cm, firmness on palpation, fixation to adjacent
            tissues, cervical lymphadenopathy, and vocal fold paralysis raise concern for
            malignancy.
            RED FLAG - Solitary nodule combined with cervical lymphadenopathy greater than 1 cm and
            vocal fold paralysis has nearly 100% positive predictive value for malignancy.
