A Cross-sectional Study on Spectrum of Oral Cavity Lesions with Emphasis on Soft-tissue Tumours: A Lesser Dealt Domain
Abstract
Introduction: The oral cavity, the beginning of the digestive system, has diverse lesions affecting it other than Oral Squamous Cell Carcinoma (OSCC). Soft-tissue Tumours (STT) are uncommon lesions. Overlapping of the signs and symptoms in diverse conditions creates significant problems for reaching their definitive diagnosis. Histopathological Examination (HPE) plays a central role in giving their final diagnosis. Assessment of the clinical features, histopathology, along with Immunohistochemistry (IHC), helps in reaching an accurate diagnosis in these cases, which further aids in the proper management of the patient. Aim: To study the spectrum of oral cavity lesions and tumours with emphasis on STT. Materials and Methods: A retrospective cross-sectional study was conducted at the Department of Pathology and Otolaryngology, Dr. Ulhas Patil Medical College, Jalgaon, Maharashtra, India included the oral cavity lesion samples received over two years (from January 2021 to December 2022) in the histopathology section of a Medical College in Maharashtra, India. A total of 170 cases were included in the study. Complete clinical information including age, sex, anatomical location, clinical diagnosis, and histological subtypes were compiled. The HPE diagnosis were classified into four categories-Non neoplastic, Benign, Epithelial Proliferative lesions {including viral/Human Papillomavirus (HPV) related}/Intraepithelial neoplastic lesions/Precursor or Pre-malignant, and malignant with special emphasis on STTs found. The data was statistically analysed and the results were presented as percentages. Full details of the soft-tissue lesions were recorded, entered into an Excel sheet, and studied for the percentage-wise distribution of various recorded parameters. Results: A total of 170 cases were found. Male:female distribution was 2.78:1, and most patients were in the seventh decade, n=38 (22.35%). The most common lesions other than SCC, n=110 (64.71%) found were mucocele, chronic inflammatory lesion and wart. The Buccal Mucosa/Gingivo-buccal Sulcus (GBS) were the most commonly involved site, n=82 (48.24%). Malignant lesions were more common in the sixth and seventh decades, with a male preponderance of 2.71:1. The uncommon STTs found were-Benign: Haemangioma/pyogenic granuloma (n=2), a Schwanomma, and a Proliferative Fasciitis (PF); Malignant: two fibrosarcomas and a high-grade sarcoma. All three malignant STTs were found in males of the sixth decade involving the buccal mucosa. Conclusion: Among the variety of lesions found in the oral cavity, HPE facilitates the recognition of the STT, especially the malignant ones, aiding in proper management. Being an extremely uncommon entity at this site, the documentation of these findings is of utmost importance.
