A 45-year-old female presented with mildly pruritic erythematous skin lesions over face, forearms and hands of 3 months duration along with history of dyspnoea for the same duration. The lesions were erythematous lichenoid discrete papules predominently distributed over photoexposed areas involving face, dorsal aspect of arms, forearms, and hands with sparing of areas covered by clothing. History of marked photosensitivity was present.
General physical and systemic examinations did not reveal any abnormality. Complete blood count, hepatic and renal functions were normal. Serum calcium was 8 mg%. Mantoux test was negative to 5TU. Rheumatoid factor, antinuclear antibodies and LE cells were negative. However, chest x-ray revealed bilateral hilar lymphadenopathy with diffuse bilateral reticulonodular shadows alongwith mild basal fibrosis. These findings were further confirmed on CT scan. Pulmonary function test revealed mild lestrictive lung disease. A skin biopsy from one of the lesions revealed non-caseating epitheloid cell granulomas with tissue stains for fungus and acid fast bacilli negative. She was given prednisolone 40 mg daily and this led to complete resolution of skin lesions and subjective improvement of dyspnoea in 2 weeks. Patient is still on treatment and follow-up with us.
The cutaneous lesions in our patient were quite suggestive of lichenoid variety of polymorphous light eruption, due to their lichenoid character and photo-distribution. Polymorphic light eruption like lesions have been described previously in sarcoidosis. To the best of our knowledge, marked photosensitivity with lesions strictly restricted to photoexposed areas have not been described in sarcoidosis.
