Sialo-odontogenic cyst--a case report.

Sialo-odontogenic cyst is an uncommon cyst of odontogenic origin that occurs in the tooth bearing areas of the jaws. These lesions are histopathologically unique, biologically aggressive and may sometimes warrant distinction from central muco-epidermoid carcinoma and botryoid variant of the lateral odontogenic cyst. Sialo-odontogenic cysts tend to recur and various factors are quoted for their recurrence viz., the presence of microcysts, thin connective tissue wall, etc. We are herewith reporting a case of sialo-odontogenic cyst for its relative rarity among the odontogenic cysts.

Basaloid squamous cell carcinoma report of a case and review of literature.

Basaloid squamous cell carcinoma (BSCC) is an aggressive distinct variant of squamous cell carcinoma that mandates recognition as a separate entity owing to the difference in its clinical behaviour. Histologically this tumor can mimic other neoplasms like adenoid cystic carcinoma, neuroendocrine carcinoma and basal cell adenocarcinoma. BSCC occurs most commonly in older men and has a site predilection for the upper aero-digestive tract. We report a case of basaloid squamous cell carcinoma for its relative rarity, which was diagnosed in a 52 year old woman, with a brief review of literature.

Cytomorphometric analysis of exfoliated normal buccal mucosa cells.

Interest in the field of oral exfoliative cytology has reemerged following advancements in the field of quantitative oral exfoliative cytology as a powerful diagnostic tool. However, even though numerous such studies have been conducted in malignant and precancerous conditions, there have been relatively few reports of similar studies on the normal mucosa, which could be used as a baseline for comparison of pathological smears. This study was undertaken to establish the average nuclear diameter (ND), cytoplasmic diameter (CD), and the nuclear cytoplasmic (NC) ratio in normal subject and to evaluate the differences in these parameters, if any, between different age groups and between males and females. The mean ND was found to range from 7.8 u to 8.28 mu, the mean CD was found to range from 46.19 mu, and the NC ratio was found to range from 0.1609 to 1822. The results of this study also showed significant variation in the CD with increasing age. All parameters showed variations with age changes in females, probably as a result of hormonal influences.
