Diagnosis and Management of Skin Disorders
It is possible that this is a case contact dermatitis from camping exposure. It is called papular/pustular and appears as raised bumps on the skin in small clusters. This distribution follows a pattern and affects the trunk, lower legs (starting point), trunk and groin. The red color indicates that the patient has experienced an allergic reaction to some allergen or irritant. This could have occurred through contact or inhalation/ingestion. There are no ancillary findings such as swelling, crusting/oozing wounds etc., so this further points towards contact dermatitis being the primary diagnosis for this patient’s condition.
Atopic dermatitis, scabies infestation and contact dermatitis are all possible diagnoses. These symptoms can all be similar, but the absence of family history or systemic signs that would suggest eczema and scabies along with the fact that it has only recently occurred after returning from camping trips makes allergic contactdermatitis more likely.
Anti-histamines can be administered orally, such as Benadryl; topical corticosteroids such hydrocortisone lotion depending on severity. Finally, cool baths could provide relief immediately. Repeated episodes should not be repeated even if they occur more often.
