The rest of the head and neck follows similar rules.
Thymoma accompanies myasthenia gravis, and thymic carcinoma is usually squamous.
Pleomorphic adenoma, the commonest salivary tumour, contains chondromyxoid stroma,
whereas Warthin tumour shows oncocytic epithelium with lymphoid stroma
and is linked to smoking.
Mucoepidermoid carcinoma, not squamous carcinoma, is the commonest salivary malignancy.
Nasopharyngeal carcinoma is driven by Epstein-Barr virus,
oropharyngeal carcinoma by HPV-16 with a better prognosis,
and erythroplakia carries a far higher malignant risk than leukoplakia.
All medullary thyroid carcinomas arise from C cells, secrete calcitonin,
deposit amyloid and ignore radioiodine.
Is the RET mutation germline?
Then MEN2 is present, and phaeochromocytoma is excluded before any thyroid surgery.
On the three axes, primary hyperparathyroidism reads high calcium and low phosphate,
secondary reads low calcium and high phosphate.
Lumps aside,
the glands behind the thyroid keep calcium in and phosphate out,
so their loss brings tetany treated with calcium gluconate.
