Actinic prurigo falls within the category of idiopathic photosensitive dermatoses, but it has several distinguishing characteristics.
The test is positive in 60%-70% of white patients with actinic prurigo and in 4%-8% of controls.
Similarly, Mexican mestizos with actinic prurigo are likely to test positive to HLA A29-B39, and Canadian Cree First Nations people tend to test positive to the HLA A24 subtype.
Native Americans are, in fact, more likely than are other patients with actinic prurigo to experience conjunctivis and/or cheilitis, which can be excellent diagnostic clues.
These were key to the diagnosis of actinic prurigo, along with the fact that his photosensitive rash consisted of itchy papules that developed 30 minutes after sun exposure.
Williams said recent publications call into question the traditional notion that actinic prurigo is a form of PMLE.
Phototesting is more sensitive in actinic prurigo, producing positive results in about 60% of patients, compared with only about 20% of patients with PMLE.
The differential diagnosis of HA includes other photosensitive disorders that present with lesions on the skin after visible light exposure, such as HV, pinpoint PMLE, lichen nitidus, and actinic prurigo. HV was ruled out on clinical morphological differences and the absence of crusts and varioliform scarring after sun exposure that are typically seen with and without dermoscopy (5).
In summary, we present a case and dermoscopic findings for a 33-year-old woman whose clinical and histopathologic features were not consistent with HA, HV, lichen nitidus, PMLE, and actinic prurigo. We are soliciting similar case presentations.
