As this variant is rare it is difficult to distinguish it from other variants of squamous cell carcinoma. It commonly originates in the head and neck region as these parts are highly exposed to the sunlight. There are very few cases reported in the literature. Here we report a case in a 30-year-old male who reported with a nodular lesion over the upper lip with no unusual signs, which was confirmed as adenoid squamous cell carcinoma after various histopathological tests.Corynebacterium diphtheriae is a gram-positive bacillus with characteristic polar metachromatic granules. It was a significant public health problem, infecting the throat and upper airways and producing a highly potent exotoxin but with the advent of diphtheria vaccine, cases have rapidly decreased. Now over the last decade, the reemergence of this infection has been noted and case reports from India have been documented. India represents 78% of globally reported cases with significant mortality despite national immunization programs in place. This case study indicates the severity of an improperly managed case, the importance of microbiological diagnosis with a special interest in molecular detection, and reinforces a resurgence of diphtheria infection.The recreational use of nitrous oxide (N2O) is a growing public health concern. Increasing numbers of young individuals are presenting to accident emergency departments complaining of adverse neurological symptoms as a result of N2O induced vitamin B12 deficiency. Despite its increasing popularity, many are still not aware of its devastating potential to cause a myriad of severe longstanding neurological impairment. Herein we present a case that highlights the effects of N2O abuse and the best way to investigate and manage such patients.Myocarditis in patients with diphtheria is a toxin-mediated complication that sets i
