Presentation reference

Is it this?

Reference only, to read alongside your own examination.

Symptoms — what the patient reports (2)

Most patients notice a palpable neck lump or have a nodule found incidentally on imaging, and most nodules cause no symptoms [neck lump]
Neck pressure or pain can occur, especially if the nodule bleeds spontaneously [bleeding]

Signs — what you find (3)

Palpation is the simplest exam method but the least sensitive, finding nodules in only 4% to 7% of the population
Concerning exam findings include a nodule over 4 cm (about 19% malignancy risk), firmness, fixation to surrounding tissue, neck node swelling, and vocal cord paralysis [lymphadenopathy · vocal cord paralysis]
A solitary nodule together with a neck node over 1 cm and vocal cord paralysis together predict malignancy with roughly 100% positive predictive value [vocal cord paralysis]

Tests (9)

Initial work-up includes history, exam, a TSH level, and thyroid ultrasound
Malignancy risk rises as the TSH level rises; a low TSH instead favors a benign nodule
A low TSH prompts a radioactive iodine or pertechnetate scan to check for an autonomously functioning nodule, which is usually benign
Ultrasound features linked to cancer include microcalcifications, irregular margins, a dark appearance, a taller-than-wide shape, and more blood flow
An incidental nodule found in a patient with a known nonthyroid cancer carries a 24% malignancy rate, versus about 5% otherwise
Fine-needle aspiration under ultrasound guidance is the cornerstone test and is preferred over palpation-guided biopsy, which has more false negatives and nondiagnostic samples
A nodule under 1 cm is biopsied only if it has more than one suspicious ultrasound feature, nearby lymphadenopathy, or a high-risk history
Ultrasound-guided biopsy is used for nonpalpable nodules over 1 cm, palpable nodules under 1.5 cm, deep nodules, or nodules near blood vessels
Cystic or spongiform nodules carry low malignancy risk and are only biopsied if they exceed 2 cm

If not this — what else fits (4)

Congenital neck masses usually appear at birth; if one instead appears later in life, that raises suspicion for malignancy
Cancers of the tongue, tonsil, or thyroid can present as a cystic neck mass
Inflammatory neck masses are usually viral or bacterial lymph node swelling, typically found around the sternocleidomastoid or in front of the trapezius muscle
A metastatic neck mass is most often squamous cell carcinoma spreading from the aerodigestive tract

LEVOTHYROXINE

1st line

Strength0.05 mg

Formoral.solid

Adult dose and duration

50-100 mcg once daily in the morning on an empty stomach ONLY if subclinical or overt hypothyroidism co-exists - long-term

Paediatric dose

Age-dependent dosing under pediatric endocrinologist supervision only if hypothyroid

Dose source

Egyptian National Drug Formulary - Endocrine System 2024 (levothyroxine monograph), Hypothyroidism, patients under 50 years age: "Initially 50 to 100 mcg daily". The formulary carries no thyroid-nodule indication; this is its hypothyroidism starting dose, the indication under which levothyroxine appears here. The ATA thyroid nodules guideline is not held in this corpus.

Why

Thyroid hormone replacement given only when a thyroid nodule is accompanied by subclinical or overt hypothyroidism, to normalise TSH; not used as suppressive therapy for a euthyroid nodule, which is no longer recommended.

Cautions

Routine TSH suppression therapy for euthyroid nodules is NO LONGER recommended.
Urgent ultrasound and fine-needle aspiration (FNA) referral is required for red-flag features (rapid growth, dysphagia, hoarseness, hard immobile nodule).
Strength is 50 mcg = 0.05 mg.

REFERRAL & SAFETY-NETTING (NO DRUG THERAPY)

1st line

Dose source

Thyroid Nodule - disease-level clinical article (thyroid-nodule-referral-full.txt)

Why

Carries the referral criteria and warning signs for this condition, which apply whichever treatment is chosen.

Cautions

RED FLAG - The specific physical exam findings that raise concern for malignancy are size >4cm, firmness, fixation, cervical lymphadenopathy, and vocal fold paralysis, and in combination they have a near-100% predictive value.
RED FLAG - FNA cytology results (Bethesda V suspicious, Bethesda VI malignant) mandate surgical referral regardless of any medical therapy.
