Introduction: COVID-19 disease is caused by SARS-CoV-2 virus and it was declared pandemic by World Health Organization (WHO) on March 11,2020. The coronavirus infection has an affinity for ACE2 receptors and by attaching to them, the virus enters the host cells. Along with many body organs like lungs, kidney, liver, upper respiratory tract, nervous system, skeletal muscles, ACE2 concentration is also found in abundance in epithelial cells of tongue and salivary glands. Materials and Methods: Recent studies, researches, documents and case reports published in the world medical literature in the year 2020-2021 were searched and documented in our study. The search engines used were PUBMED, google scholar, WEB OF SCIENCE etc. Results: Dysgeusia, xerostomia, sore throat, aphthous and herpetiform ulcers, candidiasis, enanthema, Kawasaki like lesions were the most common among various oral manifestations. Others includes plaque like changes, gingival inflammation, necrotizing gingivitis, erythema -multiforme, angina-bullosa like lesions, Melkersson-Rosenthal Syndrome, Oral mucormycosis etc.The sites of infection mainly include tongue, gingiva, hard and soft palate, buccal and labial mucosa etc. Conclusion: The etiopathogenesis of such lesions cannot be directly corelated with COVID-19 and factors such as stress, immunosuppression, co-infections, secondary lesions, opportunistic infections, systemic diseases, poor oral hygiene etc. must be considered. Management of stress is an important factor. In this review article various oral lesions are discussed in COVID-19 infection states in detail. The importance of earliest diagnosis of oral lesions is to be kept in mind to prevent further complications.

Postmenopause is a phase of life which leads physical and emotional instability from multiple health related issues. Oral health in this stage of life is also compromised. Oral health has an impact on general wellbeing of the individual as oral cavity is commonly act as a mirror to general health. Menopause is phase in a woman’s life when menstrual cycles cease by reduced secretion of the ovarian hormones, such as estrogen and progesterone. This review article has emphasized on the diverse oral presentations of peri- and postmenopausal phase of women’s life. Practicing dental surgeons and general physician should be aware of the possible association of postmenopause and its various oral signs and symptoms in this midlife phase of women. It also focuses on its symptomatic management of various oral health issues. This article explains diverse oral conditions in detailed and their management. Stress causing anxiety and depression among this midlife phase of women can lead to alteration in immunity which can again lead to various oral conditions, like lichen planus, apthous ulcer that can cause burning sensation in oral mucosa and alter the food habit. By dealing with all this diverse condition, practicing oral physician can help to reduce and manage oral manifestation of postmenopausal phase of life.

One challenging feature of head and neck pathology is that a dizzying array of sarcomatoid lesions occurs here ranging all the way from reactive to malignant and very aggressive. This makes accurate diagnosis critical. These lesions are quite diverse with great clinical and biological heterogeneity. Some are malignant while many others are benign or simply reactive in nature. For example; at mucosal sites, a well known lesion is spindle cell carcinoma (SpCC), which are overtly malignant, and the differential diagnosis then includes a number of different malignant spindle cell lesions. However, there are several benign or even non-neoplastic lesions that can sometimes be difficult to discern from SpCC, e.g. Nodular fasciitis, Proliferative myositis, Cellular schwannoma, Benign fibrous histiocytoma, Carcino sarcoma, Sarcomatoid melanoma. Fracture callus, etc. Aim of Study: There is a diagnostic challenge to the oral pathologists to differentiate dizzying array of sarcoma like lesions from other similar microscopic simulates ranging all the way from reactive to malignant and very aggressive. This article aims to review the sarcomatoid lesions of the head and neck region with emphasis on differential diagnosis histologically and immunohistochemicaly.
