We report two consecutive cases of toxic epidermal necrolysis presented to our emergency department in the past 5 months. Both patients had history of fever prior to the onset of skin manifestations and showed radiological findings suggestive of COVID-19 pneumonia and elevated D dimers. ALDEN score was used to assess the drug causality, which showed probable and possible associations, respectively. In this report, along with brief review of literature, we highlight the possible role of viral etiology, that is SARS-Cov2, in triggering toxic epidermal necrolysis.

Introduction: Taxanes are chemotherapeutic agents used in a variety of solid tumours. They are known to cause cutaneous as well as nail changes which are temporally associated with intake of drug. Nail involvement is reported in literature from some parts of the world. Aim: To study the pattern of nail changes occurring due to taxane-based chemotherapy regimens in patients suffering from malignancies. Materials and Methods: A prospective observational study was carried out in a tertiary care hospital in GMC, Patiala, Punjab, India from October 2020 to September 2021. A total of 160 adult patients undergoing cancer chemotherapy with taxanes were included in the study. After taking detailed history, nail changes were examined and confirmed by dermoscopy. The data was analysed using Epi Info 7 by CDC and Chi-square test was used to calculate the p-value. Results: A total of 144 patients (87 females and 57 males), with the mean age of 53.8 years, were screened for six chemotherapeutic cycles. Drug-induced Nail Pigmentation (DINP) was the most common nail abnormality seen in 43/144 (30%) patients after third cycle and in 105/144 (73%) patients after the sixth cycle. The most common pattern was diffuse nail pigmentation 40/105 (39%) followed by longitudinal melanonychia 22/105 (21%) after six cycles. Maximum pigmentation 52/60 (86%) was observed in patients who received taxane+adriamycin+ cyclophosphamide combination. On onychoscopy, DINP appeared as thin grey regularly arranged parallel longitudinal lines on homogenous grey background. Conclusion: Taxanes cause varied pattern of nail changes with DINP being the most common. It ranges from longitudinal bands after three cycles to diffuse pigmentation after six cycles. These nail changes show temporal relation with dose, duration, number of drugs, and colour of skin. Dermoscopy is a novel non invasive method with a good diagnostic accuracy.
