Scabies surrepticius is a unifying term that represents non-classical presentations of scabies mite infestation. A patient with scabies surrepticius is described: a man with scabies masquerading as prurigo nodularis. The 91-year-old man had metastatic prostate cancer and presented with diffuse pruritic nodules. Prurigo nodularis was suspected; however, the biopsy revealed scabies mites in the stratum corneum. He was successfully treated with topical permethrin 5% cream and oral ivermectin. In addition, the features of a woman with scabies mimicking systemic lupus erythematosus are summarized. The 47-year-old woman had idiopathic thrombocytopenic purpura and presented with malar erythema and a positive antinuclear antibody (titer 1:320). A diagnosis of systemic lupus erythematous was entertained until skin scraping and mineral oil preparation revealed scabies mites; she was successfully treated with oral ivermectin. In conclusion, Sarcoptes scabiei infestation can present with atypical clinical morphology and an absence of classical lesions such as burrows conventionally distributed in the interdigital web spaces, volar wrists, periumbilical area, or genitalia. Scabies surrepticius is a term that has been designated to describe these unusual presentations. Prurigo nodularis and systemic lupus erythematosus can be added to the litany of conditions masquerading as scabies and are included amongst the guises of scabies surrepticius.

The "itch mite" or "mange mite", Sarcoptes scabiei, causes scabies in humans and sarcoptic mange in domestic and free-ranging animals. This mite has a wide host range due to its ability to adapt to new hosts and has been spread across the globe presumably through human expansion. While disease caused by S. scabiei has been very well-studied in humans and domestic animals, there are still numerous gaps in our understanding of this pathogen in free-ranging wildlife. The literature on sarcoptic mange in North American wildlife is particularly limited, which may be due to the relatively limited number of clinically-affected species and lack of severe population impacts seen in other continents. This review article provides a summary of the current knowledge of mange in wildlife, with a focus on the most common clinically-affected species in North America including red foxes (Vulpes vulpes), gray wolves (Canis lupus), coyotes (Canis latrans), and American black bears (Ursus americanus).
