Abstract
A case of a West Indian patient is reported who developed abnormal blue‐grey pigmentation on exposed areas of skin following treatment with low dose stelazine. Oculocutaneous melanosis is a well‐recognized side‐effect of prolonged phenothiazine treatment. In this condition the areas of skin exposed to sunlight develop a violaceous, blue‐grey or slate‐grey colour in more severe cases. These characteristic changes are rarely seen now. We describe the case of a patient who developed pigmentation while taking a low dose of stelazine for 5 years.
