Objective: Plunging ranula represents mucous extravasation from the sublingual salivary gland extending to the submandibular space. Although the majority of patients present in the second or third decade of life, it rarely occurs in children. Methods: Three cases of plunging ranula in children, including one in a neonate, are described. The review of the relevant literature is also presented with a special notice to the differential diagnosis and treatment options. Results: Ranulas presented as a slow-growing, soft mass located in the submandibular area. Two patients had also oral presentation. The diagnosis was established basing on clinical signs and computed tomography findings. All cases were treated surgically using various methods. In all cases the histopathological examination confirmed the diagnosis of pseudocyst. Conclusion: Plunging ranula may be misdiagnosed especially in young children and in cases presenting only the symptoms of submandibular swelling
