PDF | The majority of oral diseases present as growths and masses of varied cellular origin. Such masses may include simple hyperplasia. The presence of a neurovascular hamartoma within the oral cavity is truly a rare entity. Scarcely reported in the literature, these hamartomas. Cowden’s Syndrome, Bannayan-Riley-Ruvalcaba Syndrome, PTEN Hamartoma Tumour Syndrome.

Essentially, understanding the dynamics of each of these disease processes forms an integral part of the appropriate treatment planning.

Hamartomas of the oral cavity

The cells are usually polyhedral in shape with a basophilic rounded nucleus. Histopathologically it shows hanartomas masses of cementum embedded in fibrovascular connective tissue surrounded by a thin fibrous capsule continuous with the periodontal ligament. Congenital granular cell tumour Congenital granular cell tumour is thought to be a variant of granular cell tumour, but the exact nature of the lesion is unclear.

The ectomesenchymal cells resembling primitive dental papilla are seen surrounding the islands and strands Figure 2.

Philpsen et al [8] in their article further went ahead to state that regarding origin and pathogenesis of the AOT, it would seem that this lesion is derived from odontogenic epithelium of the dental lamina complex or its cellular remnants located in the gubernacular cord [30]. Rhabdomyomatous mesenchymal hamartoma presenting as haemangioma on the upper lip: Histopathologically the tumour presents in forms of odontogenic epithelial strands, cords and islands distributed in the ectomesenchymal stroma.

Caution with radiotherapy is recommended until this observation can be studied further in larger cohorts of Cowden syn- drome patients.

Immunohistochemical detection of p53 and PCNA in ameloblastoma and adenomatoid odontogenic tumor. Simvastatin has been demonstrated to exhibit antitumor effects, and so the aim of the present study was to assess the effects of simvastatin on the growth of human PTEN haploinsufficient lipoma cells.

The distinguishing features of hamartomatous lesions are not certain, and often these non-neoplastic masses are indiscreetly denoted as neoplasms without weighing their pathology or biological behaviour. Multiple leiomyomatous hamartoma in the oral cavity. How to cite this URL: The odontogenic islands resemble ameloblastic islands which show peripheral arrangement of columnar to tall cuboidal cells.


Haemangiomas and vascular malformations of the maxillofacial region: Glomuvenous malformations Glomuvenous malformation GVM occurs more often in children. Clinicopathologic presentation of 3 cases.

It is an extremely rare cemento-osseous disease restricted to the jaws. The lesion present as a slowly growing, recurrent in occurrence in the soft tissues like gingiva and vestibule.

Why should I brand my topic? Most of the lesions cease to grow or regress spontaneously without intervention.

Focal areas show clear cell changes without any involvement of inflammatory cells, which suggest an absence of inducing stimuli; hence they are derived from the dental lamina [4,5]. This tumour is usually associated to the unerupted tooth and radiographically present as a well circumscribed radiolucent lesion which may or may not contain radio-opaque foci. The strand often exhibits double or triple layer of cuboidal cells which has a close resemblance to dental lamina.

It is a rare lesion of the minor salivary glands.

The initial case was reported by Norberg in
