Over recent years, targeted therapy has become one of the most important innovations in cancer treatment. Agents targeting the epidermal growth factor receptor (EGFR) are administered in patients with advanced, recurrent or metastatic malignancy. We reported the case of a 74 year-old male patient with metastatic colorectal cancer who developed an SDRIFE and acneiform eruption during molecular target therapy with cetuximab and FOLFOX.

| Introduction|| |
Over recent years, targeted therapy has become one of the most important innovations in cancer treatment. Agents targeting the epidermal growth factor receptor (EGFR) are administered in patients with advanced, recurrent, or metastatic malignancy.
Skin toxicity is one of the most common side effects of EGFR inhibitors (EGFRIs).
| Case Report|| |
In August 2018, a 74-year-old male with colorectal cancer RAS wild type, with multiple liver metastases, received chemotherapy in accordance with the folinic acid, fluorouracil, and oxaliplatin (FOLFOX) scheme for 12 cycles, and cetuximab 250 mg/m2 weekly until March 2019. Due to disease response, he continued weekly maintenance therapy with Cetuximab.
In May 2019, he was referred to our Plastic Surgery Unit due to the presence of a papulopustular eruption located at the mouth area, without mucosal involvement. Multiple superficial erosions with thin, light-brown to golden-yellow crusts, and vegetating lesions were observed [Figure 1]a. At the same time, he developed a symmetrical erythematous sharply demarcated erythema on the gluteal area [Figure 1]b. Patient history suggested a possible drug eruption. A microbiological culture of the crusting lesions of the mouth area showed the presence of Staphylococcus aureus and Streptococcus anginosus, whereas the gluteal skin resulted negative. We started a therapy which included cleansing, removal of crusts, application of wet dressings, and fusidic acid cream at the mouth area, with a complete resolution in 2 weeks [Figure 2]a. The gluteal area was treated with topical steroids and zinc oxide cream, with a complete resolution in 1 week [Figure 2]b. A prophylaxis with minocycline 100 mg daily for 8 weeks was also started.
| Discussion|| |
Cetuximab is a part of the EGFRIs used in metastatic or nonresectable colorectal cancer with EGFR and without RAS (wild-type) mutations.
It is generally better tolerated than conventional chemotherapy. The main side effects are acneiform eruptions, xerosis, pruritus, paronychia, hair abnormalities, mucositis, trichomegaly, hypertrichosis, alopecia, photosensitivity, and urticarial. Moreover, we recently highlighted the appearance of intertrigo such as eruption during therapy with cetuximab.
The alterations in EGFR signaling promote cell growth and inflammation, but the pathogenesis of these eruptions has not been fully elucidated. In fact, EGFR signaling has been shown to be critical to the normal development of skin and hair in human and mouse models. Even if infections do not seem to be the driver factor, the disruption of the skin barrier can lead to secondary bacterial or viral infections, most frequently with S. aureus, although in our patient Streptococcus anginosus was also detected.
Symmetrical Drug-related Intertriginous and Flexural Exanthema (SDRIFE) is a symmetrical erythematous rash of the gluteal and intertriginous areas observed after exposure to beta-lactam, in particular amoxicillin, although there are many reports of other systemic drugs also implicated.
The clinical course usually is benign and self-limited; however, it could progress to a generalized maculopapular exanthema if the eliciting drug is not withdrawn. Treatment of SDRIFE consists of discontinuation the triggering drug. In addition, antihistamines and topical/systemic glucocorticosteroids can be used,,, especially when it comes to life-saving therapies such as cancer therapy.
There are only two published cases regarding SDRIFE in association with Cetuximab and FOLFOX, and one case in a patient treated with gefitinib.
In our opinion, the development of a SIDFRE-like reaction during oncologic treatment is now being carefully evaluated due to increased awareness of this eruption as a potential cutaneous adverse effect of EGFRI.
