Dear Editor-in-Chief Myxoid tumors of oral cavity encompass a broad spectrum of lesions, primarily neoplastic.(1) The significant variations in the biological behaviour; ranging from completely harmless to malignant neoplasm they require an accurate histopathological diagnosis to ensure a proper treatment. (2) Because of the considerable overlapping between the clinical and histopathological features, this group of tumors often produce a diagnostic difficulty to the clinicians and oral pathologists.(3) An exhaustive review of the literature reveals that there is no approved classification of myxoid tumors of oral cavity. A simple working classification of myxoid tumors is proposed here.

Spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. Spindle cell neoplasms can affect the oral cavity. In the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. This article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology. How to cite this article: Shamim T. The Spindle Cell Neoplasms of the Oral Cavity.

Lipomais a most common benign neoplasm of mature adipose tissue in trunk and extremities. The oral cavity rarely affected by this neoplasm(1-4%) and more occurs in buccal mucosa. Floor of the mouth is rarely affected. Usually its size is less than 3 cm. The present report shows an unusual case of large lipoma (5.5 cm in greatest dimension) in the floor of the mouth of a 68- year- old male and review of the literature.

Background and Objectives: There are a few studies on histopathologic type of oral lesions especially from Iran. The aim of this study was to survey the oral lesions in Babol, northern Iran.
Methods: The histopathology records were retrospectively reviewed for all lesions of oral cavity and jaws, during the years 1990 to 2009. The data were collected from the archive of pathology and analyzed based on age, gender, site of lesion and histopathologic type.
Results: From the 465 studied specimens, the mean age was 34.6 ± 20.3 years old; female to male ratio was 1.1: 1. The most frequent lesions were inflammatory/reactive (60%), tumoral (25%), cystic (14.2%), and tumor like lesions (0.8%), respectively. The most common inflammatory lesion was mucocele as 54 cases (19.4%). Ameloblastoma was the most common odontogenic tumor (55.5%). The most common odontogenic cyst was radicular cyst (44.8%), and the most common non-odontogenic cyst was mucus retention cyst (75%).
Conclusion: It seems that the malignant oral and jaw lesions have been more prevalent in this study compared to others, thus, the patients must be biopsied earlier to rule out malignant oral lesion in histologic examination.

Background and Objective: Different mechanisms may lead to the development of soft tissue tumor-like lesions in the oral cavity. Many of these lesions can be identified as specific entities on the basis of their histopathological features and are divided into fibrous, vascular, and giant cell types. The purpose of this study was to establish the relative prevalence of the different histopathological aspects of biopsies of oral soft tissue tumor-like lesions at School of Dentistry, Kerman Univ. Med. Sci. Materials and Methods: Documents and records of 260 patients with localized lesions of oral tissues diagnosed from March 1996 to March 2004 were reviewed. The lesions were classified into either fibrous or soft hemorrhagic lesions. Clinical data regarding age, gender, location, and treatment of lesions were obtained for each case. Data included in the present retrospective study were analyzed by SPSS statistical software (13.5) using t- test and chi-square tests. Results: A total of 260 surgical specimens of lesions of the oral cavity presented clinically were studied; 143 cases (55%) had fibrous lesions and 117 cases (45%) had soft hemorrhagic lesions. The fibrous lesions included 91 cases (63.6%) of gingival lesions, whereas 98 cases (83.76%) of the soft hemorrhagic lesions had gingival lesions. The patients were simultaneously treated by excisional biopsy and elimination of the chronic irritant. Conclusion: Oral lesions are often detected by dental professionals, surgeons and ENT specialists. Knowledge of the frequency and presentation of the most common oral lesions is beneficial in developing a clinical impression of such lesions encountered in practice.
