How to describe a lump? [ANY LUMP]
She Cuts The Fish PERfectly
Site Size Surface Colour Contour Consistency Tenderness Temperature Transillumination Fluctuance Fixity Fields Pulsatile Expansile Reducible
Differentials for midline neck lump?
Thyroid: Physiological goitre Multinodular goitre Graves' disease Hashimoto's Thyroiditis Thyroglossal cyst Thyroid cyst Adenoma Carcinoma de Quervain's thyroiditis (rare)
Non-thyroid: Lipoma Dermoid cyst Epidermal cyst Abcess Lymphoma (rare)
Differentials for lateral neck lump?
By structure:
Artery - Carotid aneurysm, subclavian aneurysm, carotid body tumour (chemodectoma)
Nerve - Neurofibroma, schwannoma
Lymphatic vessels - Lymphangioma (simple, cystic hygroma)
Lymph nodes - Infective, neoplastic (1ry, mets), granuloma
Salivary glands - Infective, autoimmune, neoplastic
Larynx - Laryngocele
Pharynx - Pharyngeal pouch
Branchial arch remnant - Branchial cyst/sinus/fistula
Superficial/skin - Lipoma, epidermal cyst, abcess, dermoid cyst (atypical)
First line investigation in thyroid lump?
Fine needle aspiration
Main primary thyroid tumours?
Benign (90%):
Adenoma - functioning or non-functioning
Malignant (10%):
Papillary carcinoma - 70%, younger patients, multifocal, better prognosis, thyroidectomy + radioiodine
Follicular carcinoma - 25%, younger patients, prognosis worse in older patients, thyroidectomy + radioiodine
Medullary cell carcinoma - 5%, part of MEN I, Ca of calcitonin-producing C cells thus ^ calcitonin, thyroidectomy, does not take up radioiodine
Anaplastic carcinoma - Rare, rapidly growing and invasive tumour in older patients, usually incurable, treatment palliative (may need tracheostomy and radiotherapy)
Lymphoma - Both Hodgkin’s and non-Hodgkin’s, treatment chemo
Complications of thyroid surgery?
Immediate: Bleeding Infection Damage to recurrent laryngeal nerve Parathyroid resection/damage Hypothyroidism
