Infantile Hemangioma of the Upper Lip: Report of a Rare Case With a Brief Review of Literature.

Hamartomas are tumor-like abnormalities typified by the presence of cellular proliferation indigenous to the native site. However, hamartomas maintain growth cessation without the potential for further growth or malignant transformation. Hamartomas are commonly seen in the lungs, kidney, liver, and spleen and rarely occur in the orofacial region. Various hamartomatous oral lesions include hemangiomas, lymphangiomas, tori, exostosis, dens invaginatus, dens evaginatus, odontomas, nevi, and cherubism. Infantile hemangiomas are benign vascular tumors that emerge soon after birth and experience rapid growth within the first year. Oral hemangiomas affect up to 6.4% of infants and are more common on the ventral surface of the tongue, as opposed to oral vascular malformations, which are more prevalent on the lips. It also has a 3:1 female-to-male predominance. Afterward, their growth usually stabilizes and enters a prolonged, incomplete involution phase. Uncomplicated hemangiomas generally exhibit spontaneous resolution, whereas few can leave behind scars and telangiectasias on the external surface of the skin on which it occurs. Thus, lesions located in anatomically sensitive regions necessitate vigilant surveillance and treatment. This paper deals with an asymptomatic swelling of the upper lip in a four-year-old female child but with problems in aesthetics, speech, and feeding. A thorough history, clinical examination, positive diascopy, ultrasonography, and histopathology confirmed the diagnosis of infantile hemangioma.
