Solitary neurofibroma of the gingival

Neurofibroma is a benign peripheral nerve sheath tumor, usually found in association with Von Recklinghausen's disease of the skin. The solitary variant commonly occurs in the head and neck region, mostly affecting young adults. They are characteristically slow-growing masses, often asymptomatic and have been found most commonly in the tongue and buccal mucosa. A recent literature review highlighting incidences in various other locations has been tabulated here. We also report a case of a solitary neurofibroma of the gingiva in a 72-year-old male of 15 years duration. Histopathology revealed a fibromyxoid stroma with sinuous nerve bundles with buckled nuclei

Morphometric Analysis of Nuclear Features and Volume-Corrected Mitotic Index in the Prognosis of Oral Squamous Cell Carcinoma / Oral Science International

In the present study, an objective and reproducible evaluation of mitotic activity and nuclear morphometric factors was attempted in 30 patients of oral squamous cell carcinoma with a view to predicting local relapse and survival. Various nuclear parameters and volume-corrected mitotic index were calculated and compared with the recurrence and death of the study group (n = 30). Volume-corrected mitotic index (M/V index) was the single best prognosticator for recurrence of oral squamous cell carcinoma (p = 0.008 for recurrence; p = 0.015 for death). The combination of M/V and SD of nuclear area (forward stepwise regression) was a more efficient and better predictor of survival (Log rank test, Kaplan-Meier's survival analysis; χ² = 17.46, p = 0.00001). The present study proved the effectiveness of the M/V index in predicting the biological behavior and the outcome of oral squamous cell carcinoma patients.

Maxillofacial fibrous dysplasia.

Fibrous dysplasia is a non- neoplastic hamartomatous developmental fibro osseous lesion of bone. This paper provides a brief overview of fibrous dysplasia in a historic perspective and highlights the controversies in fibrous dysplasia seen in the cranio- maxillofacial lesions. A case report of a young woman is presented who was diagnosed as having maxillofacial fibrous dysplasia, thereby making an attempt to use this term in cases with relatively limited facial bone disease.
