Mucoceles on the ventral surface of the tongue derived from the Blandin Nuhn glands are considered quite unusual (1), which because of their clinical characteristics and location may be confused for other pathologies like vascular lesions, pyogenic granulomas, squamous papillomas, among others.
The pathology reported changes compatible with extravasation-type mucocele of the ventral surface of the tongue, which because of its location and presentation corresponds to a mucocele of the Blandin Nuhn glands. The patient continued with out-patient follow up for 10 months without clinical evidence of recurrence.
The Von Ebner glands drain on the base of the circumvallate and foliate papillae on the dorsal lingual surface; the Weber glands, mucin exclusive producers, are located on the lateral surface of the tongue, having as drainage site the lingual tonsil crypts; lastly, the Blandin Nuhn glands are found near the tip of the ventral surface of the tongue, and are surrounded by lingual muscles near the medial line.
The cystic formations or mucoceles of the Blandin Nuhn glands have been reported as unusual; according to Harrison (4) in a review of 400 mucoceles of the oral cavity only nine originated in the tongue, constituting 2.3%; according to Saza et al., (5) mucoceles of the Blandin Nuhn glands were found in 9.6% of 385 mucoceles studied.
