In simple words: Acne varioliformis is a skin condition where small bumps and blisters form, mainly on the scalp and hairline. These can become sore and eventually leave small scars that look a bit like pockmarks. Sometimes, it can be a milder form with tiny, itchy blisters that crust over without scarring. While bacteria can be found in the blisters, the exact cause isn't clear.

Acne varioliformis, a chronic relapsing skin disorder, involves follicular papules and pustules that develop into depressed, variola-like scars. This condition primarily affects the anterior hairline and scalp.While Staphylococcus aureus and Corynebacterium acnes have been isolated from the pustules, the exact etiology remains unknown.It typically occurs between the ages of 30 and 50, often with a female predominance. In acne necrotica varioliformis, the papules and pustules evolve into depressed scars resembling those seen in smallpox (varioliform). These lesions may be painful. Another form is called acne necrotica miliaris, it is characterized by small, very itchy vesicopustules that form superficial crusts and erosions without scarring.

Example 1: A 40-year-old woman presents with painful, recurring bumps along her hairline that eventually leave small, pitted scars.Upon examination, the dermatologist diagnoses her with acne varioliformis., A 35-year-old man experiences small, itchy blisters on his scalp that crust over. While there is no scarring, the persistent itching prompts him to seek medical attention. The dermatologist identifies the condition as acne necrotica miliaris, a variant of acne varioliformis., A child presents with small pustules and papules on their scalp which are very itchy. The lesions resolve without scarring.A diagnosis of acne necrotica miliaris, another variant of acne varioliformis, is made.

Documentation should include a detailed description of the lesions (papules, pustules, scars), their location, and any associated symptoms like pain or itching. Patient history, including age and gender, should also be noted.Any relevant laboratory results, such as bacterial cultures, should be documented. Photographs of the lesions can be helpful for tracking the progression of the condition.

** Although the term "acne" is used, acne varioliformis isn't directly related to typical acne vulgaris. It's important to emphasize this distinction to avoid confusion and ensure appropriate treatment.
