Clinical management of bullous pemphigoid-The importance of cytology in diagnosis.

Bullous pemphigoid (BP) is a common immune-mediated blistering disorder with predominant skin involvement and occasionally oral manifestations. Vesiculobullous lesions of the oral mucosa present with similar clinical features, and hence arriving at a clinical diagnosis is aided by a valuable chairside investigation, exfoliative cytology. Cytology done in the present case ruled out pemphigus because of the absence of Tzanck cells in the smear. Biopsy and direct immunofluorescence further confirmed the diagnosis of BP. Treatment initiated with systemic steroids and immunomodulators, along with oral topical application of triamcinolone acetonide resulted in complete remission in 2 months. This case report highlights the role of cytology in the diagnosis of vesiculobullous lesions and management protocol for BP patients presenting with simultaneous skin and oral lesions.

COVID-19 Coinfection With Mucormycosis in a Diabetic Patient.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a form of ß-Coronavirus of the Coronaviridae family, has been causing infection among humans worldwide leading to a pandemic emergency. New strains of SARS-CoV-2 have been evolving unceasingly, presenting with various systemic and oral manifestations. There has been an increase in the incidence of secondary infection in the coronavirus infected individual either due to pre-existing factors or the virus by itself is causing such infection, which is still unclear. As it is already known, immunocompromised and uncontrolled diabetic patients have an increased chance of developing mucormycosis. Herein, we report a case who presented with a swelling in the left cheek, eye, and avascular necrosis intraorally, post COVID-19 infection.

The Involvement of Temporomandibular Joint in Psoriatic Arthritis: A Report of a Rare Case.

Psoriatic arthritis (PsA) is a chronic inflammatory condition affecting psoriatic patients. Its clinical manifestations in patients can vary over time, advancing from one joint to the next with an intermittent pattern of exacerbation and remission. The condition shares similar manifestations with rheumatoid arthritis (RA), ankylosing spondylitis, and reactive arthritis; hence, a comprehensive examination is required for a proper diagnosis and management. It is associated with an increased risk of comorbidities affecting patients' well-being. There have been few incidences of involvement extending to the temporomandibular joint (TMJ), but a proper record needs to be maintained to evaluate its part in PsA. In this report, we present a case of PsA in which the patient complained of ear pain and was discovered to have early alterations in the TMJ.
