Primary non-Hodgkins’s lymphoma is a very uncommon lesion, accounting for 0.6% in jaws. As the lesions frequently resemble other disease such as chronic osteomyelitis, odontogenic or any secondary neoplasms, further evaluation and histopathologic examination allow early identification for appropriate treatment. The purpose of this case report is to describe a rare case of non-Hodgkin’s lymphoma of the mandible, explore the diagnosis and workup based on immunohistochemistry.

Calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a rare odontogenic epithelial neoplasm. So far, nearly 200 cases have been reported in the literature. We are reporting a case of CEOT in a 42-year-old male patient with painless bony swelling in the mandible. The clinical, radiographic, and histopathologic features are discussed with relevant references.

An oral ulcer is described by repeated or painful oral aphthae, in which oxidative stress apparently leads to its pathogenesis. The present study has been undertaken to evaluate the effects of fresh leaves and flowers of Tagetes erecta gel on oxidative stress and antioxidant levels on oral ulcer models in albino Wistar rats. The oral ulcer was induced by incision wound model and then treated with the Tagetes erecta flower and leaf extract gel for 7 days. The antioxidant activities of catalase (CAT), superoxide dismutase (SOD), the levels of glutathione (GSH) and malondialdehyde (MDA) were measured in rat buccal mucosal tissues. The antiulcer effects of Tagetes erecta leaf and flower extracts (2.5% and 5%) gel were intercompared with the standard drug, Triamcinolone. Ulcer induced rats exhibited elevated levels of MDA and reduced activity of SOD, GSH and CAT when compared to the control rats. The nonequilibrium levels of antioxidant were observed in rat mucosal tissues indicate that body’s antioxidant status was depleted with an oral ulcer. Tagetes erecta leaf and flower gel (5%) has been found to have higher significant antioxidant activity compared with ulcer induced rats by reducing the levels of MDA and by increasing the activities of SOD, GSH and CAT in response to oxidative stress due to induction of oral ulcers in a rat model. The findings thus justify the traditional use of Tagetes erecta to heal oral ulcer by increasing the antioxidant status and decreasing the free radical production.

Introduction: Varicella zoster virus is a highly infectious a-herpesvirus, pathogenic only to humans. The primary infection of varicella zoster virus causes chickenpox, which is contagious and primarily infects children and adolescents in India. Following the primary infection, the virus remains dormant in sensory root ganglia. Activation of the dormant virus in later stages of life causes herpes zoster infection which may vary from subclinical infection to typical zoster, scattered vesicles, zoster sine herpete or disseminated zoster, which depends on the individual's immune status. Case report: In this case series, we present two patients with herpes zoster involving the mandibular branch of the trigeminal nerve. Cytology revealed characteristic features of the infection including nuclear moulding, multinucleated giant cells and ballooning degeneration. Conclusion: More recently, patients presenting with herpes zoster have been reported to have sub-clinical Covid-19 infection, suggesting a possibility that herpes zoster might be an indicator for latent Covid-19. Timely detection and treatment of this infection can reduce the risk of post herpetic neuralgia.

Tagetes erecta(African marigold) has various medicinal values. The present study has been undertaken to evaluate the effects of extracts of the fresh leaves and flowers of Tagetes erecta on oral ulcer models in Wistar albino rats. The anti-ulcer activity of the extracts of tagetes erecta (2.5% and 5%) was compared between the leaf and flower and also with the standard drug, Triamcinolone. Phytochemical screening of plant extract, extract action on oral ulcer and histopathology analysis were carried out. Tagetes erecta leaf and flower extracts have showed the presence of alkaloids, flavonoids, and carotenoids. Results showed that Tagetes erect leaf extract showed significant oral ulcer protective activity (83.6%)  when compared with the standard drug Triamcinolone. In the present work, it can be concluded that the hydro alcoholic leaf and flower extractHistopathologys of Tagetes erectagel have better potential against oral ulcer which supports the traditional claims in folklore medicine.
