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.

Immunohistological features in adenomatoid odontogenic tumor: Neural fibrolipoma or fibrolipomatous ov of nerve FLHN is a tumour-like lipomatous process. The results of the present study suggest that simvastatin may be beneficial for patients with inoperable PTEN haploinsufficient lipomas.
We’ll suggest content based on your keywords. OGCF was described by Philipsen et al the histopathology of the tissue shows no encapsulation with dense fibrous connective tissue containing large multinucleated giant cells, proliferating odontogenic islands with occasional squamous metaplasia. Figure 3 Ameloblastic fibroodontoma. A case report with immunohistochemical analysis and treatment with high-power lasers.
Glomuvenous malformation GVM occurs more often in children. It is an exceptionally rare congenital lesion of the oral cavity. The role of these markers helped in understanding the vavity and aggressive ha,artomas of the tumours. Philpsen and Slootweg have suggested ABFO as a hamartomatous lesion, though histologically indistinguishable from complex odontoma [24,25].

Hamartomas of the oral cavity.
The epithelial cells show a variety of patterns in form rosettes which appear to be formed around a central space or lumen, which may be empty or contain small amounts of eosinophilic material showing positive staining for amyloid like material . Bishop K, Alani A. Oral and Maxillofacial Pathology: Dilated blood vessels with thick cemental mass containing cementocytes. The lack of paediatric reports of PHTS-associated cancer may be explained by previous diagnostic limitations.
Leiomyomatous hamartoma is another rare entity which commonly involves the midline of palate and tongue. Dent Res J Isfahan ;9: Clinicopathologic presentation of 3 cases.
Irregular to round concentric layered calcified bodies exhibiting a Leisegang ring pattern may also be evident . The tumor exhibits population of spindle-shaped epithelial cells that form sheets, strands, or whorled masses of cells in a scant fibrous stroma. How to curate as a team? There is a formation of the dentinoid or osteodentin material hamaetomas an occasional presence of enamel fibrillar and key hole patterns.
This observation is consistent with prior experimental studies in cell culture, which have predicted an association between germline PTEN loss-of-function mutations and hypersensitivity of normal tissues to radiotherapy.

They represent a well-circumscribed flat area of brown to black mucosal pigmentation. The majority of oral diseases present as growths and masses of varied cellular origin. Philipsen et al  in their study have suggested to continue reporting of unusual or rare histomorphological features, immunohistochemical findings and applications of molecular biological techniques for better understanding of this unusual odontogenic tumour .

Histopathologically it shows hypocellular masses of cementum embedded in fibrovascular connective tissue surrounded by a thin fibrous capsule continuous with the periodontal ligament.
