ABSTRACT
Fixed drug eruption (FDE) is a cutaneous adverse drug reaction characterized by recurrence of lesions at the same sites each time a specific drug is taken. Oral mucosal involvement is rare. Nonsteroidal anti-inflammatory drugs are one of the most common offending drug groups in FDE; however, selective cyclooxygenase-2 inhibitors, such as etoricoxib, are rarely implicated. We present a case of oral mucosal and cutaneous FDE induced by etoricoxib that, to the best of our knowledge, is the first reported case of this nature. We describe the diagnostic challenges and review the pertinent literature. The value of drug provocation testing and patch testing in FDE is also discussed.

PURPOSE OF REVIEW: The aim of this article is to provide clinicians and pathologists with an understanding of the aetiopathology, pathogenesis and classification of vulval neoplasia and their molecular correlates. RECENT FINDINGS: There is an increased understanding of subcellular changes in vulvar malignancies. These provide the direction for further research and aid personalised treatment for patients. The article explores concepts of the aetiology of vulvar cancer and updates the reader with the equivalence of terminology of preneoplastic vulval disease. The differential diagnosis of squamous neoplasia and their clinicopathological correlation is detailed. The salient findings from recent literature into the understanding of the disease of squamous cell neoplasia and rare vulvar malignancies are summarised.

Background. Plantar warts are a common presenting skin complaint caused by the human papillomavirus. 1st line therapies include cryotherapy and topical salicylic acid. Where there is resistance to these treatments, consideration is made for 2nd line therapies, including intralesional bleomycin, imiquimod, 5-fluorouracil, and photodynamic therapy. We present a case of bilateral persistent plantar warts, resistant to treatment with repeated cryotherapy and topical salicylic acid over a 6-year period. Following a patient initiated decision to discontinue their statin medication, we observed rapid clearance of plantar warts without change to standard therapy or their environment. This case correlates with emerging literature demonstrating a link between statin medication and proliferation of HPV through increased levels of FOXP3+ regulatory T cells.
