Actinic reticuloid is a rare, chronic, persistent photosensitive dermatosis first described by Ive in 1969. It is included under a spectrum disorder- chronic actinic dermatitis. Light spectrum involved in pathogenesis of actinic reticuloid (AR) is ultraviolet A (UVA), ultraviolet B (UVB), and visible light as well. It usually affects elderly men and lesions have a typical distribution in photoexposed areas.
A 61-year-old woman, resident of Pune, a retired police officer, presented to our institute with itchy, dark lesions on face, and outer aspect of both forearms since 9–10 years. The lesions appeared insidiously on the forehead with gradual involvement of both cheeks, temples, nose, and forearms. On inquiry, the patient gave the history of regular, prolonged photo-exposure. The patient consulted many doctors for the above complaints and was prescribed multiple topical medications; however, there was no relief. She did not give the history of lesions elsewhere on the body, no preexisting dermatosis, and no history of any drug intake prior to the appearance of lesions. She is not a known case of hypertension, diabetes mellitus, or any other comorbidity.
On examination, the skin type of the patient was Fitzpatrick type V. There was presence of multiple, thick hyperpigmented lichenified indurated plaques with scaling on photoexposed areas such as forehead, temples, cheeks, nose, extensor aspect of both forearms, and dorsum of hands. There were no lesions elsewhere.
The differential diagnosis considered here were photodermatitis, subacute cutaneous lupus erythematosus, Jessner’s lymphocytic Infiltration of skin, and lymphoma cutis.
The findings of the routine laboratory investigations such as complete blood count with differentials and comprehensive metabolic panel were within normal limits. Photopatch test and patch test could not be performed due to the patient’s financial constraints.
A punch biopsy of the skin was performed from the lesions; the histopathological examination revealed hyperkeratosis, parakeratosis with prominent granular cell layer, and irregular acanthosis with elongation of rete ridges. Superficial dermis showed perivascular inflammatory infiltrate composed of lymphocytes and few polymorphs. The subcutis showed congested blood vessels and sparse mononuclear inflammatory cells [Figure 1].

On the basis of the clinical features and histopathology report, the diagnosis of AR was made.
The patient was counseled about the disease and measures of strict photoprotection. The patient was started on oral azathioprine 100 mg/day and hydroxychloroquine 300 mg/day in tapering doses. The topical treatment was in the form of a broad-spectrum sunscreen during the day and potent topical corticosteroid––clobetasol propionate 0.1% cream diluted with an emollient applied at bedtime for 2 weeks.
With regular follow-up up to 6 months, our patient showed an excellent response to the treatment with a marked reduction in thickness of plaques and no new lesions [Figure 2].

AR has been reported in Caucasians, Latin Americans, Japanese, and Indians., Not many cases have been reported in the Indian scenario. The mainstay of treatment is photoprotection. The occupation of the patient must be taken into account while counseling the patient regarding photoprotection. Oral corticosteroids are used for the initial control of disease and in cases of acute flares. As the disease process requires a long-term therapy, the need for steroid-sparing immunosuppressive drugs arises. These include azathioprine,, cyclosporine hydroxychloroquine,, and mycophenolate mofetil. Other drugs such as thioguanine, danazol, thalidomide, etretinate, infliximab, and IFN-α have been reported to be effective in small case series.
