“…Peng et al summarized all reports regarding VC and explained that since PIOVC has no recurrence or metastasis, it does not require any forms of neck dissection, and removal of primary lesion alone can lead to good prognosis. The seventh case was reported by Kamarthi et al in 2016, on VC at OC in the maxilla with confirmed verrucous transformation of the cystic lining [ 21 ].…”

BackgroundVerrucous carcinoma (VC) accounts for 1–10% of cases of squamous cell carcinoma (SCC) in the oral cavity, and 75% of VC occur in the oral cavity. Only 3% of primary intraosseous squamous cell carcinomas (PIOSCC), which means SCC occurring primarily in the bone, are VC. Verrucous carcinoma arising from odontogenic cysts (OC) is very rare, with only seven cases reported to date.Case presentationThis study reported a case of a patient who underwent partial maxillectomy and neck dissection for VC that occurred in the right anterior maxilla. The patient was admitted to the emergency department at our institution 8 years ago and showed cystic lesions in the anterior maxilla on facial computed tomography (CT) images. Treatment through other departments including assessment of laceration in the mental region and only suture was performed. This report highlights a very rare case of VC in the right anterior maxilla arising from a previous cystic lesion.ConclusionsSince PIOSCC can arise from OC, appropriate treatment of intraosseous cysts and regular radiologic evaluation are necesssary. Surgical exicision of the primary lesion without neck dissection can lead to good prognosis for patients with primary intraosseous verrucous carcinoma.

“…Verrucous proliferation in a cystic lining is one such rarity. To the best of our knowledge only eight cases of odontogenic cysts with verrucous proliferation have been reported in English literature [1–8], of which six were reported as verrucous carcinomas arising in odontogenic cysts. We describe a case of an infected odontogenic cyst exhibiting verrucous proliferation and melanin pigmentation.…”

Verrucous proliferation arising from odontogenic cysts is a rare entity. We report an unusual case of an infected odontogenic cyst with verrucous proliferation and melanin pigmentation in a 13-year-old male patient who presented with an intraoral swelling in relation to impacted teeth 26 and 27. The enucleated lesion was diagnosed as an odontogenic keratocyst and the patient died within two years of presentation due to multiple recurrences. The clinical, radiological, and microscopic features of the lesion are presented with an attempt to discuss the etiopathogenesis. The case hereby reported is uncommon with only eight cases reported in the literature.

“… 2 Reviewing English literature, to the best of our knowledge, there are only 3 cases of PIOC arising in OOC to date. 3 , 4 , 5 OOC accounts for about 1% of all odontogenic cyst, and it is considered as less aggressive than OKC with less than 2% in recurrent rate. Although malignant transformation of odontogenic cyst is rare, the pathologists should carefully examine the differentiation pattern of cystic epithelial lining.…”
