Massive macroglossia secondary to myxedema: an unusual case
Macroglossia is classified as true macroglossia, which exhibits abnormal histology with clinical findings, and relative macroglossia, in which normal histology does not correlate with pathologic enlargement.

This report, published in the Journal of Oral & Maxillofacial Surgery, describes an atypical case of morbidity with massive macroglossia secondary to myxedema; the macroglossia enlarged over a 3-month period before being the patient presented to the concerned department for health.

Substantial enlargement of the tongue (16 cm long × 10 cm wide) was first attributed to angioedema, which was refractory to the discontinuation of lisinopril and a C1 esterase inhibitor. A core tongue biopsy examination was performed to rule out angioedema, amyloidosis, myxedema, and idiopathic muscular hypertrophy.

Interstitial tissue was positive for Alcian blue and weakly positive for colloidal iron, which are correlated with hypothyroidism and a diagnosis of myxedema. However, the macroglossia did not resolve after correcting for hypothyroidism.

The patient required a wedge glossectomy for definitive treatment. She recovered unremarkably, with excellent cosmesis and preservation of lingual and hypoglossal function. There are some case reports of massive macroglossia but none with myxedema as the primary etiology.
