Polymorphous light eruption (PMLE) is the most common photodermatoses worldwide. Photodermatoses refers to skin disorders which are exacerbated or induced by light. Harmful effects of light on skin are almost entirely due to radiation within the ultraviolet spectrum of the sun’s emission. UVR having wavelength between 200 to 400 nm penetrates epidermis (UV- B ) and dermis (UV- A)  and can induce sunburn, tanning, epidermal hyperplasia, photoaging and photo- carcinogenesis. Photodermatoses is classified in four groups: (A) Idiopathic (immunologically mediated) photodematoses; (B) Drug/ chemical induced photodermatoses; (C) Genetic and metabolic photodermatoses; and (D) photo-aggravated dermatoses.[1,2]

PMLE is types of idiopathic photodermatoses which occurs mostly in 3rd – 4th decade of life and have female prepondence. It develops few hours or days after light exposure on sun exposed parts. It is relapsing in nature. Clinical picture of PMLE may be polymorphic or monomorphic lesions. Eruptions can be small, itchy papules, vesicles or plaques on erythematous background. The skin lesions resolve spontaneously within several days of ceasing sun exposure. [2]

Differential diagnosis of papular or papulovesicular type include photoallergic eczema, ictus or prurigo simplex. Plaque-type lesions must be differentiated from delayed onset solar urticaria, erythema multiforme and lupus erythematosus (LE). [3]

Photoprotection is the mainstay treatment in all photodermatoses. Other treatment methods are systemic or tropical steroids, antihistamines and skin hardening by preventive UV phototherapy and ⁄or psoralen plus UVA (PUVA). [1, 2, 3]

According to homoeopathy, photodermatoses is predominantly disease of psoric miasm.

Homoeopathic treatment is aimed at managing treatment of manifested polymorphous light eruption during acute phase and prevention of recurrence even on exposure to light using homoeopathic medicines selected on the basis of individualisation to the highest degree clinically possible.

Here, a case of photodermatoses is presented that was treated with the homoeopathic medicines.
