Background: Fixed drug eruption (FDE) represents a drug-related cutaneous reaction.Many drugs been associated with this clinical entity, with continually evolving documentation of implicated agents and clinical presentations. A bullous form can occur although it is rare.Objectives: To assess the epidemiological and clinical characteristics of FDE. Methods: We retrospectively analysed all FDE cases who presented to the ClinicalPharmacology Department at the University Hospital, Monastir, Tunisia, for allergy workup.Results: The mean age of the 41 confirmed FDE cases was 43.8 ± 15.5 years. The time between first lesion onset and FDE diagnosis was less than 1 month for 13 patients (31.7%). Fifteen patients had bullous lesions. The upper limbs were the most common location (65.9% of cases). The patch tests were positive in 27 cases; a provocation test yielded a positive response in the four cases tested. Nonsteroidal anti-inflammatory drugs (NSAIDs) were involved in 51.2%, antibiotics in 24.4%, and other analgesics in 19.5%. The most common offending drug was mefenamic acid in 24.4% of cases. Bullous lesions were significantly associated with paracetamol intake (P = .014; odds ratio 16.7; 95% confidence interval: 1.76-158).Conclusions: NSAIDs and antibiotics were the most implicated in inducing FDE; paracetamol was associated with bullous lesions.

Our series of LPPI seems that this disorder is underreported mainly among 3 dark-skinned persons as we have seen these ten cases within three years.

topical glucocorticoids treatments, the skin lesions resolved quickly. To our knowledge, this is the first report of ACD caused by moxibustion. Due to the worldwide application of moxibustion as a TCM treatment, both patients and doctors should be aware of severe allergic reactions related to its use.
