front teeth of the upper jaw since birth.The soft tissue growth is now causing difficulty in biting food and is visible during smiling and speaking, causing an esthetically displeasing appearance.Over time, this soft tissue mass has also caused spacing between the maxillary central incisors.Medical history was normal, and there was no relevant family history pertaining to the lesion.Intraoral examination revealed a firm, pedunculated, teardropshaped, tubular growth on the incisive papilla between the right and left primary central incisors, extending 3-4 mm below the incisal edge of the primary central incisors.The mass was IntroductIonA hamartoma is defined as a benign growth composed of an abnormal mixture of cells and tissues normally found in the area of the body where the growth occurs.They are haphazardly arranged and are native to their origin. 1Hamartomas are not very common in the oral cavity and are usually found in the liver, spleen, pancreas, lungs, and kidneys.Most oral cavity hamartomas are of vascular origin, and those originating from other tissues are rare. 2Oral hamartomas composed of smooth muscle fibers are known as leiomyomatous hamartomas and are rarer than those composed of fibrous, neural, and epithelial tissues.Among published cases of leiomyomatous hamartoma, most are found on the posterior tongue, hard palate, and gingiva. 3To the best of our knowledge and literature search to date, only 19 cases of leiomyomatous hamartoma of the median maxillary gingiva have been reported in Japanese and English literature worldwide.All these cases mimicked clinical features similar to congenital epulis, but their histological features differed from those of congenital epulis.The literature also lacks reports of leiomyomatous hamartoma with high labial frenulum.Thus, this paper intends to report a rare case of congenital oral midline leiomyomatous hamartoma of the incisive papilla with high labial frenulum attachment in a 6-yearold girl, clinically mimicking congenital epulis. case descrIptIonAn otherwise healthy 6-year-old female child accompanied by her father reported to the Department of Pediatric Dentistry with a chief complaint of slow-growing soft tissue overgrowth over the 1-3,5,
