Bilateral inner thighs with 10 x 12 cm raised, confluent, erythematous papules and blisters in various stages: The location of the original rash provides information on the manner of spread. This information, in concert with the morphology of the rash, is pivotal for determining the cause of the rash. Therefore, it is the most significant active problem (MSAP)
Left ventral forearm with 6 cm linear, erythematous papules and yellow-red blisters: This secondary location indicates the pattern of the rash’s spread. Along with its similar appearance to the original rash, this secondary rash is related to the MSAP
itching progressing to tenderness: The itchy nature of the rash along with its progression to tenderness is pivotal for deciding the order of the differential diagnosis list This finding is related to the MSAP.
New exposures: Wild brush plants: Exposure to wild plant material is a key historical element that could indicate an origin for the MSAP. Since a direct correlation is uncertain, it is unknown if this finding is related to the MSAP
New exposures: Hot tub: Hot tub water can contain bacteria (such as Pseudomonas) and chemicals that cause skin imitation or infection, so exposure to it is a key historical element that could indicate an origin for the MSAP Since a direct correlation is uncertain, it is unknown if this finding is related to the MSAP.
New exposures: Oily suntan lotion: Exposure to the chemicals, preservatives, and scents of a new lotion could indicate an origin for the MSAP. This new topical lotion can lead to skin irritation or can intensify sunlight rays in some cases. Since a direct correlation is uncertain, it is unknown if this finding is related to the MSAP
New exposures: Scallops: Exposure to new food could indicate an origin for the MSAP Since a direct correlation is uncertain, it is unknown if this finding is related to the MSAP.
