The current treatment of psoriasis patients with biologic agents in the Kingdom of Saudi Arabia (KSA) is mainly based on clinical experience. Although there are published international guidelines for treatment with biologics, such as the European S3 guidelines (a joint project of the European Dermatology Forum, the European Academy of Dermatology and Venereology, and the International Psoriasis Council), many nations have found it beneficial to develop country-based guidelines that incorporate specific regional aspects of therapy (legal and practical). With the expanded role of biologic agents in the treatment of psoriasis in Saudi Arabia, a need for local Saudi guidelines has become evident. Here we present a practical approach to the evidence-based clinical administration of biologics for professionals who treat patients with psoriasis.
A case of nevus lipomatosus cutaneous superficialis is presented, wherein the lesion occurred as a gluteal swelling in a 6-year-old boy. On histopathology examination, it consisted of typical superficial expanses of mature adipose tissue in the papillary dermis of the polypoidal lesion. It was accompanied by 2 unusual findings, which consisted of the focal presence of lipocytes at the epidermal–dermal junction in the pagetoid manner and the prominent deposition of calcium resulting in calcinosis cutis–like lesions. Calcinosis cutis in the present case occurred as dystrophic calcification in focal fat necrosis changes of the lesion, whereas the focal pagetoid spread of fat cells is likely related to the same hamartomatous adipose tissue growth that ultimately results in the nevus lipomatosus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
