A 1½-yr-old boy, known case of
b thalassemia major
developed erythematous, mildly pruritic, non-tender blisters on both
pinnae (Fig. 1), after packed red blood cell transfusion.
These lesions persisted, even after stopping transfusion, for next two
days. Aspiration of the fluid from the blisters showed predominance of
eosinophils without any pus cells; fluid culture was also sterile. We
treated the patient with oral cetrizine (antihistamine), and the lesions
subsided after 48 hours without any residual pigmentation or scarring.

Auricular blisters may occur due to delayed type of
hypersensitivity reaction in allergic and irritant contact dermatitis
where in the acute phases, the skin is erythematous, edematous, and
pruritic. Small papulovesicular lesions with exudation and crusting are
also present. However, auricular blisters following acute transfusions
have not been reported earlier. Other differential diagnoses are
otohematomas (unilateral, non-pruritic and follows trauma), lymphocytoma
(an infection caused by Borellia burgdorferi that usually occurs
on ear margin or lobe and typically appears as erythematous, tender
swelling), and photodermatosis (erythematous, intensely pruritic,
lesions following sun exposure).
