Pimecrolimus induced tinea incognito masquerading as intertriginous psoriasis.

A 58-year-old, obese, male, army officer was presented with tinea incognito of the groin masking intertriginous psoriasis. According to his history, he had pruritic, symmetrical erythematous eruption of the groin of 2-month duration that he treated himself by using topical pimecrolimus 1%. This medication had been prescribed for his 8-year son's atopic dermatitis by the paediatrician.

Mycobacterium marinum is an atypical mycobacterium usually found in non-chlorinated water. It rarely disseminates, except in the setting of a severely immunosuppressed patient, and usually follows a sporotrichotic type of distribution. We report the case of a 45-year-old man who had ankylosing spondylitis and was receiving infliximab and isoniazid for latent tuberculosis.
