Peripheral odontogenic fibroma (WHO type) of the newborn: a case report

Abstract

Despite the rarity of POF in a newborn, this lesion should be included as a possible diagnosis to focal gingival growth.

The Histological Spectrum of Myxoma, Myxofibroma /Fibromyxoma and Odontogenic Fibroma- “A Chicken And Egg Situation”

“…1 The histopathology of the peripheral odontogenic fibroma (POF) is similar to central odontogenic fibroma (COF) -WHO type and is seen only in the teeth bearing areas. 2,3 Microscopically, it shows collagenous background containing inactive odontogenic rests and/or mineralized tissue. It can also show some myxomatous stroma in its collagenous background and can undergo myxomatous degeneration as well.…”

Oral subcutaneous midline leiomyomatous hamartoma presenting as congenital incisive papilla overgrowth in a toddler

“…[5] Although very rare, peripheral odontogenic tumors in newborns were also reported and should be included in the differential diagnosis. [6] The congenital epulis cells are negative for neural, fibroblastic, myofibroblastic, myogenous, vascular, and histiocytic markers, and there are not evidences that congenital epulis grows after the birth. [7] The majority of benign tumors in the young are probably developmental rather than true neoplasms.…”

Pulp Polyp Associated with a Natal Tooth: Case Report

“…This delayed presentation of a pulp polyp after traumatic injury to the tooth is consistent with the initiation and progression of this type of lesion. 3 The differential diagnosis of this lesion should include pyogenic granuloma, 13,16 peripheral ossifying fibroma, 7,14,17,18 reactive fibrous hyperplasia, 15,19,20 peripheral odontogenic fibroma, 21 gingival fibrous hamartoma 22 and pulp polyp. 3,4 Table 1 presents four of the abovementioned lesions in comparison to the patient in this case report.…”
