Fig. 2 Clinical features of FDE and GBFDE. Patients with FDE can present with (a) a solitary lesion consisting of a well-dened, oval-shaped, red-to-purple patch and can also present with (b) several discrete well-demarcated

associations might differ in different countries or different clinical settings.
dusky-red patches. Patients with GBFDE usually present with multiple variously sized, well-dened erythematous or hyperpigmented patches with blisters or erosions on the whole body (c, d)
Patients with GBFDE tend to be older than
those with FDE and SJS/TEN (Paulmann and Mockenhaupt 2015; Cho et al. 2014). Such patients usually present with large areas of well­demarcated red-to-purple or hyperpigmented patches with various extents of blisters or erosions

on the whole body (Fig.2c, d). Sometimes, it is difcult to differentiate GBFDE from SJS/TEN based solely on cutaneous presentations. Mucosal lesions can also be found in 40–50% of GBFDE patients (Cho et al. 2014). As in FDE, the time interval between the intake of drugs and the devel­opment of lesions in GBFDE is short, with a mean value of 3days (Cho etal. 2014). There is a lack of consensus regarding the denition of GBFDE. Our group has proposed that GBFDE might be dened as a condition characterized by widespread blisters and erosions with typical FDE lesions involving at least 10% of the body surface area and distributed on at least 3 of 6 dif­ferent anatomical sites, including the head and neck, front of the trunk, back, upper extremities, lower extremities, and genitalia (Cho etal. 2014). On the other hand, Lipowicz etal. have proposed that, in order to make a diagnosis of GBFDE, 2 or 3 out of the following criteria should be fullled (Lipowicz etal. 2013). These criteria include (1) similar reaction in the past; (2) fewer than two mucous membranes involved, with the absence of spots or target lesions; (3) large and well­demarcated blisters and erosions; and (4) lesions and erosions on at least two different sites of the body. Although these two denitions are not exactly the same, suchcriteria may beuseful in distinguishing GBFDE from localized forms of FDE and SJS/TEN.
4.2 Dierential Diagnosis
The differential diagnoses of FDE are many and is dependent on the presentation of FDE (Paulmann and Mockenhaupt 2015; Shiohara
2009). For a solitary FDE lesion or a limited
number of FDE lesions, differential diagnoses include contact dermatitis, insect bite reaction, trauma, lichen planus pigmentosus, urticaria pig­mentosa, autoimmune progesterone dermatitis, and erythema multiforme. For GBFDE, the dif­ferential diagnoses include SJS, TEN, burns, graft-versus-host disease, bullous pemphigoid, and staphylococcal scalded skin syndrome.
Among these differential diagnoses, distin-
guishing GBFDE from SJS/TEN can be chal-
lenging(Paulmann and Mockenhaupt 2015). The lesions of FDE or GBFDE usually do not present with target lesions or spots, which are more fre­quently seen in SJS/TEN and erythema multi­forme (Paulmann and Mockenhaupt 2015; Lipowicz etal. 2013). In addition to clinical pre­sentations, a histopathological examination may help to differentiate FDE from other differential diagnoses.
4.3 Culprit Drugs
The causative medications of FDE and GBFDE vary among countries due todifferent prescription patternsand causality is also likely to evolve with time (Sehgal and Sirvastava 2006; Savin 2001). Although many medications have been implicated (Table 1), nonsteroidal anti- inammatory drugs (NSAIDs), acetaminophen, and antibiotics are the most commonly reported culprit drugs. NSAIDs have been reported as the leading causative drugs in reports from Taiwan (Cho etal. 2014; Lee etal.
2012), Singapore (Heng etal. 2015), Korea (Jung
et al. 2014), and Tunisia (Fadhel et al. 2019). Meanwhile, acetaminophen was identied as the most common culprit drug in one report from

France (Brahimi etal. 2010), whereas the antibi­otic co- trimoxazole (a combination of sulfa­methoxazole and trimethoprim) was the top-ranked offender for FDE in reports from India (Sharma etal. 1996), Bangladesh (Rahman 2014), Pakistan (Mahboob and Haroon 1998), Iran (Kavoussi et al. 2015), and Turkey (Ozkaya­Bayazit 2003). There is no difference in culprit drugs between FDE and GBFDE.

4.4 Prognosis
The prognosis of FDE is generally good. Once the causative drug is suspended, the lesions are usually self-limiting and will resolve gradually. Nevertheless, with each repeated exposure, the number of lesions may increase (Paulmann and Mockenhaupt 2015). As shown in Fig.3, a patient with GBFDE presented with widespread red-to-

buttocks (a, c, e). These lesions recurred and progressed to become blisters and erosions after reexposure to the cul­prit drug (b, d, f)

purple patches with erosions (Fig. 3a, c, e). The area of detachment markedly enlarged the next timethe FDE recurred(Fig. 3b, d, f). The prognosis of GBFDE is thought to be better than that of SJS/ TEN by most physicians. However, Lipowics etal. found in a case-control study of 58 GBFDE patients matched by age and extent of skin detachment to 170 patients with SJS/TEN that the mortality rate was slightly but not signicantly lower for patients with GBFDE (odds ratio 0.6, 95% condence interval 0.30–1.4) (Lipowicz et al. 2013). Their results put into question the general belief that theprognosis ofGBFDE is better thanSJS/TEN.It is possible that this was due to the fact that the extent of skin lesions is a severity marker (Pfutze et al. 2007). Another possible explanation is that patients with GBFDE are older than those with SJS/TEN, which may result in greater disease andtreatment-related morbidity and mortality.
5 Investigations
Conrming the culprit drug is one of the corner­stones of care, as correct identication can pre­vent recurrences. Oral challenge or provocation is by far the gold standard to conrm the caus­ative medication (Shiohara 2009). While there is no standardized method for performing the oral challenge in patients with FDE, a sub-therapeutic dose of the suspect drug, such as a dose one-tenth the size of the therapeutic dose (Shiohara 2009), or even a full dose of the drug (Phillips et al.
2019), is usually used and is relatively safe in
most of the cases. Besides the dosage, there is also a lack of standardized protocol with respect to the timing of the oral provocation. However, performing the challenge 1–2 months after the
remission of the eruptions is suggested by most experts (Phillips etal. 2019; Shiohara 2009).
In addition to systemic provocation tests,
patch testing is also a reliable method for deter­mining the possible culprits in patients with FDE, especially in those patients with multiple suspected drugs. A positive patch test result can be obtained in around 40% of the patients (Phillips et al. 2019; Andrade et al. 2011). In brief, suspected drugsaremixed in petrolatum or vehicles with a concentration of 20% (Brockow etal. 2002) or 30% (Barbaud etal. 2001). Drug patch tests should be performed at the sites of previous FDE lesions rather than on the normal skin on the back. The best timing for performing a patch test has yet to be determined, however, a delay of at least 4–6weeks after the resolution of the lesions is suggested by most experts in order to avoid false positive reactions, false-negative reactions, and the aggravation of the disease (Phillips etal. 2019). Severalfactors may con­tribute to a false negative drug patch test result. Firstly, theoptimal concentration and penetra­tion ability of the patch-tested drug is unclear.Secondly, patients may react to metabo­lites of the causative drugs rather than to the drugs per se. As such the use of a drug patch test without its metabolites may yield a negative result (Andrade etal. 2011).
Although lymphocyte transformation test
(LTT) is used to determine drug causality in many different drug eruptions, including SJS/ TEN, drug reaction with eosinophilia and sys­temic symptoms (DRESS), maculopapular eruptions (MPE), and acute generalized exan­thematous pustulosis (AGEP) (Pichler and Tilch 2004), its role in FDE is not yet estab­lished (Phillips etal. 2019; Shiohara 2009).

6 Management
There is no consensus regarding the management of patients with FDE and GBFDE.However, as with other drug eruptions, the removal of the cul­prit drugs is the most important step (Paulmann and Mockenhaupt 2015). In most cases of FDE, the cutaneous lesionsrapidlyimprove after with­drawal ofthe causative drug. Although there is still insufcient evidence, some patients may benet from topical or systemic corticosteroids. One study from a tertiary hospital in Korea reported that around 40% of the patients received no medical treatment, around 43% applied topi­cal corticosteroids, and around 11% received sys­temic corticosteroids (Jung etal. 2014). All of the patients in the study recovered well from the disease.
Patients with GBFDE usually improve after the discontinuation of the culprits, just like FDE (Paulmann and Mockenhaupt 2015; Lipowicz etal. 2013; Cho etal. 2014). However, for patients with extensive skin detachment, comprehensive supportive care in a reference center is suggested. As with SJS/TEN, patients with GBFDE should be monitored for disease progression, wound infections, electrolyte imbalance, and possible deterioration of internal organ function. Mucosal lesions should also be managed since involvement of the lips and genitalia is common. Pain control, the avoidance of trauma and irritation of the mucosal surfaces are vital in the care of these patients. In severe mucosal lesions, parenteral nutrient supplementation and urine catheteriza­tion might be needed. Systemic corticosteroids may be benecial in the management of patients with GBFDE.According to our own unpublished data regarding 36 patients with GBFDE, all of them received systemic corticosteroid treatment, and there was only 1 mortality during the acute stage of the disease. Nevertheless, the evidence remains anecdotal and further investigations are needed to evaluate the role of systemic corticoste­roids in the management of patients with GBFDE.

Lichenoid Drug Eruptions

1 Introduction
Lichenoid disorders are inammatory dermatoses characterised clinically by at-topped, pruritic, papular lesions and histologically by a band-like inltrate of lymphocytes in the papillary dermis. Lichen planus (LP) is the most typical and well­recognised of the lichenoid dermatoses and pres­ents with rm, shiny, polygonal, 1–3mm papules with a red to violaceous colour and overlying ne white lines known as Wickham’s striae. Grey­brown pigmented macules may result upon reso­lution of primary lesions. On mucosal surfaces, Wickham’s striae are also often seen (Tziotzios etal. 2018; Shiohara and Mizukawa 2018).
LP-like or lichenoid drug eruptions (LDE) may be difcult to distinguish clinically and his­tologically from classic LP (Tziotzios etal. 2018; Shiohara and Mizukawa 2018; Ardern-Jones and Lee 2016). Identication of a drug cause may be difcult as the latency period between drug administration and onset of rash is variable and may be prolonged, up to several months or even years (Halevy and Shai 1993). Furthermore, reso­lution of the rash after discontinuation of the causative drug may take weeks to months (Halevy and Shai 1993), adding to the uncertainty of the diagnosis. Causality may be conrmed by re-

exposure to the drug, but may not be acceptable to the patient.
2 Epidemiology
LDE is generally uncommon though specic reports on incidence rates are lacking. In fact, most epidemiological studies on cutaneous adverse drug reactions (CADRs) do not mention LDE.One study reported that LDE accounted for only 4% of all CADRs in a tertiary hospital in India (Qayoom etal. 2015). Approximately 10% of all LP cases are drug induced (Ardern-Jones and Lee 2016).
Age of presentation does not differ much between LDE and LP, reportedly ranging from 44 to 66years for LDE (Halevy and Shai 1993; Lage etal. 2012; Fessa etal. 2012; West etal. 1990) and 47 to 50 years for LP (Lage et al. 2012). Paediatric LDE is rare (Payette etal. 2015) but may result from childhood vaccinations. There is reportedly no gender bias (Tziotzios etal. 2018).
3 Description ofFeatures
Clinical and histological features which distin­guish LDE from LP are summarised in Table1. LDE tends to present with LP-like lesions (Fig. 1) which are more generalised, polymor­phous, lack Wickham’s striae and have a more eczematous or psoriasiform appearance (Fig.2).

Photodistribution is more common in LDE and may be a useful diagnostic clue (Shiohara and Mizukawa 2018). Mucosal involvement (Fig.3) is less common in LDE than in LP (Shiohara and Mizukawa 2018).
Differential diagnoses to consider include LP-like contact dermatitis [e.g. to methacrylic acid esters (Kawamura etal. 1996) and dimethyl fuma­rates (Guillet et al. 2009)], lichenoid keratosis (Pitney et al. 2016), paraneoplastic pemphigus (Tey and Tang 2009; Lim etal. 2018) drug-induced subacute cutaneous lupus (Crowson and Magro
1999), dermatomyositis (Al-Najjar et al. 1985),
graft-versus-host disease (Hymes etal. 2006) and secondary syphilis (Tang etal. 2004).

1981), chloroquine (Savage 1958)] were well-
recognised to cause LDE but have become less commonly used.
Relatively new drugs which affect the immune system have now been reported to cause LDE.These include vaccines, for example, hepati­tis B (Saywell et al. 1997; Rebora et al. 1999; Ferrando et al. 1998; Calista and Morri 2004; Schupp and Vente 1999; Limas and Limas 2002; Al-Khenaizan 2001) and human papillomavirus vaccines (Laschinger etal. 2015), interferon (IFN) therapy (Bush etal. 2017) and anti-HIV therapy [e.g. efavirenz (Baumrin et al. 2018), tenofovir (Gupta et al. 2015)]. In recent years, biological therapies [e.g. tumour necrosis factor [TNF] inhib­itors (Inoue et al. 2017; El Habr et al. 2014; De Simone etal. 2008; Darrigade etal. 2016; Andrade etal. 2015; Utsu etal. 2012; Gonzalez etal. 2018)], targeted oncological drugs [e.g. imatinib (Sendagorta etal. 2009; Gómez Fernández etal.
2010; Sudha etal. 2011; Ena etal. 2004; Dalmau

2002; Kawakami etal. 2009; Kuraishi etal. 2010)]
and immune checkpoint inhibitors (Hwang etal.
2016; Cogen et al. 2018; Min Lee et al. 2018;
Coleman etal. 2019; Curry et al. 2017; Shi etal.

Arsenic was the rst drug reported to cause LDE in 1929 (Almeyda and Levantine 1971). Since then, LDE has been reported to a long and grow­ing list of drugs (Table2). Many commonly used drugs, for example, beta-blockers, thiazide diuretics, angiotensin-converting enzyme inhibi­tors and non-steroidal anti-inammatory drugs (NSAIDs), are now recognised to cause LDE. Drugs which have been recognised to be associated with LDE at certain anatomical loca­tions, for example, sun-exposed areas or mucosa, are listed in Table3.
Older drugs such as gold (Penneys et al. 1974, Glenert 1984, Russell et al. 1997), penicillamine (Seehafer et al. 1981) and anti- malarials [e.g. quinine (Dawson 1986), quinacrine (Bauer
4.1 Biologics
While TNF-inhibitors have well-known clinical efcacy in treating inammatory conditions, it is now recognised that they may cause paradoxical inammatory skin reactions (e.g. psoriasis). Numerous cases of LDE due to anti-TNFs have been reported (Inoue etal. 2017; El Habr etal.
2014; De Simone et al. 2008; Darrigade et al. 2016; Andrade et al. 2015; Utsu et al. 2012;
Gonzalez et al. 2018). Interestingly, LDE has been reported to develop in a patient after switch­ing from iniximab to its biosimilar, suggesting possibly different immunogenicity of the biosim­ilar drug (Gonzalez etal. 2018). Change in thera­peutic class of biologics may still re-elicit the
