We read with interest the article by Recalcati et al. about the report of cutaneous manifestations in COVID‐19 patients. We would like to highlight that some potentially severe manifestations in these patients are not directly related to the coronavirus but to the medications administered.

We would like to highlight that some potentially severe manifestations in these patients are not directly related to the coronavirus but to the medications administered.(1)

A 49-year-old-woman with morbid obesity, and no other relevant antecedents, was admitted in the Intensive Care Unit, due to severe respiratory failure. Chest x-ray showed bilateral lung diffuse opacities predominantly involving the upper and middle fields. SARS-CoV-2 RT-PCR rendered a positive result. The patient required invasive ventilatory support in the intensive care unit for 24 days. Throughout this period, treatment with interferon beta (250 mg/24h), hydroxychloroquine (200 mg/12h); azithromycin (500 mg/24h), ceftriaxone (2 g/12h), lopinavir-ritonavir (800-200/24h); methylprednisolone (40 mg/12h), and tocilizumab (600 mg single dose) was administered. After successful extubation, the patient was transferred to the pneumology ward remaining asymptomatic. All the drugs where interrupted except for methylprednisolone (tapered to 16 mg daily). Seven days later, respiratory worsening was observed with cough and crackles on pulmonary auscultation. Empiric treatment with cefditoren (400 mg/12h) was started. The following day, the patient suffered an episode of fever (38.4ºC). Blood tests revealed neutrophilia [7.75 x10 3 /μl; Normal Range (NR), 1.9 -7.3 x10 3 /μl; last measurement, 3.11 x10 3 /μl] and C-reactive protein level of 59 mg/l (NR, 0 -5 mg/l). At that time, a skin rash was noticed.

Upon physical examination, a confluent reddish macular rash was observed, mainly on the trunk, but also involving the neck, face, arms, and axillary and neck folds. Small widespread pustules developed over the macules. No mucosal involvement was seen. Clinical diagnosis of Acute Generalized Exanthematous Pustulosis (AGEP) was issued. Therefore, cefditoren

Histological analysis showed subcorneal pustules with abundant inflammatory infiltrate, papillary edema, and few eosinophils within superficial dermis. Subsequent cultures of pustular content were negative. Thus, the diagnosis of AGEP was confirmed. The Euro-SCAR score was 11 points. Cefditoren, a cephalosporin-derived beta-lactam, was the probable culprit drug (Naranjo score of 7).

Finally, further studies should investigate cross-reactions between cephalosporins, and the role of cefditoren as causative agent of SCARs.
