Anogenital lichen sclerosus et atrophicus lesions in a case series of cancer patients on immunotherapy
Lichenoid reactions are one of the most frequently observed toxicities with anticancer agents and, recently, a rapid emergence of immunotherapies in oncology has hastened the need to better characterize their unique toxicity profiles, particularly for less common skin toxicities, including anogenital lichen sclerosus et atrophicus (LSA). This case series describes four patients with advanced cancer (one melanoma, two lung cancers, and one kidney tumor) developing LSA lesions while receiving an immunotherapy. Medical records from 2017 to 2020 were retrospectively reviewed. Two patients received pembrolizumab, anti-programmed cell death-1 (PD-1), one nivolumab, anti-programmed cell death-1 (PD-1), and one ipilimumab, an immune checkpoint inhibitor. LSA emerged after a median of 3 months (range, 2–4 months) from starting immunotherapy. All LSA cases were grade 2. Three cases occurred on the penis and one case on the anus. All patients improved after a specific treatment for LSA, and no LSA-related antineoplastic treatment interruption/life-threatening condition were reported. To date, this is the first case series of LSA lesions associated with immunotherapy. Early LSA recognition and management is helpful in cancer patients on immunotherapy allowing a long survival and treatment response
Purpura after application of EMLA cream in two children.
The eutectic mixture of local anesthetic cream, a 1 : 1 mixture of prilocaine and lidocaine, 2.5% each, is frequently used in pediatric and dermatologic practice to obtain local anesthesia. Side effects include transient skin blanching, erythema, urticaria, allergic contact dermatitis, irritant contact dermatitis, hyperpigmentation, and purpura. We report two children with a purpuric reaction after application of this mixture cream. Purpura after application of this anesthetic cream is a rare nonallergic reaction and only 17
occurrences have been reported, to our knowledge, in the literature. Patch tests could not be performed in our two patients because of lack of parental consent but we suggest that the purpuric reactions were most probably of toxic origin.
The pathogenesis of purpura after application of eutectic mixture of local anesthetics cream, which resolves within 2 weeks without dermatologic sequelae and without any specific therapy, is complex. The lesions are probably caused by the direct effect of the cream components on the vessels but many other factors,
such as atopic dermatitis, prematurity, subjective predisposition to purpura, trauma, and thrombocytopenia may play important pathogenetic roles
