  1. What is your probable clinical diagnosis?


The probable clinical diagnosis is “Ranula”.

There are various etiological factors that have been attributed to the pathogenesis of ranula but the most accepted one is that it is mainly due to the trauma – direct trauma or from surgery to the floor of the mouth. In this, there is a rupture of the excretory duct resulting in extravasation of mucous in surrounding tissue leading to the formation of a pseudocyst.
