Plunging epidermoid cyst of the floor of mouth is indeed an uncommon entity. A 34-year old Malay
gentleman had presented to our centre with a floor of mouth lesion that extended into the submental
region. Clinical findings and imaging studies pointed towards the impression of a plunging ranula.
Histopathological examination of a completely excised mass via intraoral approach, confirmed the
diagnosis of an epidermoid cyst. He was well on follow up with no subsequent recurrence. We discuss
the nature of epidermoid cyst and its surgical management.
Neurofibromatosis Type 1 (NF1), also known as von Recklinghausen’s disease is a multisystem genetic disorder that occurs with an incidence of 1 in 4000 live births. Plexiform nmeurofibroma (PN) is a rare important variant of NF1, seen in 5 to 15% of cases. We report a 7-year-old boy, without family history of neurofibromatosis presented with left neck swelling associated with multiple café au lait spots for one-year duration. Computed tomography of head and neck revealed an extensive soft tissue lesion involving the left parapharyngeal, carotid space and parotid space encasing the left internal and common carotid artery until its origin at the arch of aorta with erosion of the basiocciput. He underwent transcervical excision of the lesion, which was confirmed histopathologically as PN.
