“…An analogous entity, actinic superficial folliculitis (ASF), was described in 1985 by Nieboer, who reported two cases of a photoinduced, nonpruritic superficial pustular eruption presenting in a similar distribution to AA. 2 In 1985, Verbov postulated that AA and ASF were the same entity, based on the prominent overlap of clinical features, and suggested they should both be classified as AF. 3 Phototesting has not always been reported to produce the eruption in AF.…”

A new approach to actinic folliculitis: prophylactic narrowband ultraviolet B phototherapy

et al. 2021

Background. We have observed an increasing number of patients referred to the Scottish Photobiology Service (SPS), who were later diagnosed with actinic folliculitis (AF) and had positive phototesting results. Treatment options for AF are limited, with only a few reports in the literature. The use of prophylactic narrowband ultraviolet B (NB-UVB) phototherapy for AF has not previously been described, and we report on this for the first time. Aim. To analyse the clinical characteristics, phototesting results and responses to treatment for patients with AF diagnosed by the SPS. Methods. We undertook a retrospective review over 10 years of all case notes of patients who were assessed and diagnosed with AF through the SPS, based at the Photobiology Unit, Dundee, UK. Results. All 10 patients were women. Mean age of onset was 25 years and mean time to referral for investigation was 7 years. The commonest site involved was the face, with the main clinical feature being monomorphic pustules appearing after sunlight exposure. The eruption could be provoked with iterative doses of broadband UVA irradiation in five patients. All patients were offered photoprotective advice and prophylactic NB-UVB phototherapy. Five patients proceeded with phototherapy; four of these completed the desensitization course and all four reported either a delay in symptom onset or total prevention of rash induction, with complete efficacy of desensitization maintained for 3 years in one patient. Conclusion. We demonstrate the successful use of UVA provocation testing as a diagnostic tool in AF. Additionally, we recommend the use of prophylactic NB-UVB phototherapy in AF as an effective and well-tolerated approach. MethodsThis case series included all patients with a diagnosis of AF who presented to the SPS between January 2010 and December 2019. We retrospectively

“…There are few case reports detailing ASF. ASF was first described in 1985 by Nieboer, reporting two patients with a recurrent, monomorphic, superficial pustular folliculitis arising on the shoulders, upper trunk and upper extremities, 24 -36 hours after exposure to sunlight [1]. A short time later, Verbov described two similar patients with a recurrent eruption of monomorphic follicular lesions presenting as pustules of the shoulders, arms and trunk, during warm periods [5].…”

“…While the differential diagnosis of pustules is broad, several defining features can aid in narrowing down the possibilities in an efficient manner: the patient's age and general health, the distribution and the duration of the lesions. Many follicular conditions associated with exposure to intense sunlight or heat or with immune alterations have been described, namely actinic superficial folliculitis (ASF) [1]- [4], actinic folliculitis (AF) [5]- [7], acne aestivalis (AA) [8] [9], disseminate and recurrent infundibulofolliculitis (RIF) [10]- [12], steroid acne (SA) [13] [14] and cytotoxic folliculitis in acute graft-versus-host disease (CFGvHD) [15] [16]. These conditions share some clinical and histological similarities, as discussed below [3].…”

The authors report the clinical case of a 29-year-old Caucasian woman who presented with clinicopathological findings and a previous outbreak all suggestive of actinic superficial folliculitis, a rarely reported and probably misdiagnosed phototoxic sun-induced dermatosis first described by Nieboer in 1985. Despite the exuberance of this cutaneous eruption, it is usually auto-limited, reinforcing the importance of its knowledge, for eviction of unnecessary diagnostic tests and therapies. Mechanisms of pathogenesis postulated include ultraviolet A radiation and local heat. This photodermatosis presents as monomorphic, superficial, pustular, and non-pruritic folliculitis affecting the upper body but not the face, usually arising on neck, back, shoulders and upper trunk. The follicular pustules emerge 24 -72 h after intense exposure to heat and/or sunlight and fade spontaneously in 5 -10 days, without scarring. This patient showed a 48-hour latency period; the number of pustules and area of the body affected were proportional to the duration of the sunlight exposure; the eruption lasted approximately 10 days. Actinic superficial folliculitis has a specific histology with follicular subcorneal sterile pustules and a mixed inflammatory infiltrate around hair follicles, probably secondary to keratinocytes and Langerhans cells involvement in the immunomodulatory actions of ultraviolet radiation. Recurrence under identical conditions may occur, after a latency period of at least 4 weeks, but usually about 1 year. Actinic superficial folliculitis and related follicular conditions are probably underdiagnosed and subsequently there is insufficient scientific information available to clinicians. Being familiar with these entities is of the utmost importance, since it can be crucial for their management.
