Photolichenoid dermatitis is an uncommon eruptive dermatitis that often occurs in association with a photosensitizing drug. Photodermatitis, in general, is an uncommon clinical manifestation of human immunodeficiency virus (HIV), most often affecting patients of African and Native American descent. Photolichenoid dermatitis has infrequently been reported in patients with HIV who have not been exposed to a photosensitizing drug. We report a case of an African patient with a photodistributed depigmenting eruption without exposure to a photosensitizing drug. Histologic examination revealed a patchy perivascular and bandlike lymphocytic infiltrate with melanophages, interface changes, and dyskeratotic keratinocytes, consistent with photolichenoid dermatitis. Laboratory examination was significant for a positive HIV-2 antibody. Photolichenoid dermatitis may be a presenting sign of HIV infection and may not necessarily be associated with exposure to a photosensitizing drug. Testing for HIV should be done in patients who present with photodistributed depigmenting eruptions, even in the absence of exposure to a photosensitizing drug, and particularly in patients of African and Native American descent.

We report a case of a newly recognized primary immunodeficiency due to biallelic mutations in CARMIL2 manifesting as an actinic prurigo-like photodermatitis, allergic diathesis and recurrent infections in a child. We present this case to highlight a rare phenotype seen in this T-cell immunodeficiency and provide an overview of other dermatologic manifestations among published reports of this condition.
