We report a case of tongue swelling resulting from ectopic osseous proliferation within a pseudocystic stroma in a 24 year old healthy female. The patient presented a history of dull pain and gradual onset of a swelling at the ventral aspect of the tongue. The lesion had a mixed consistency with areas of sponginess andfluctuancy interspersed with nodular bony hardness and yielded a sanguinous aspirate.

Polymorphous low grade adenocarcinoma: literature review and report of lower lip lesion with suspected lung metastasis.

Polymorphous low grade adenocarcinoma (PLGA) is an uncommon tumour that affects minor salivary glands mainly. It was known to be clinically benign and histologically polymorphic; sometimes misdiagnosed as pleomorphic adenomas, monomorphic adenomas, malignant pleomorphic adenomas, adenoid cystic carcinomas and adenocarcinoma not otherwise specified. More information about PLGA is cumulating in the current literature with new evidences suggesting that the tumour may not be as indolent as it was previously thought.

Giant macroglossia with persistent nonocclusion in a neonate.
