ABSTRACT

Diagnosis: EXOGENOUS OCHRONOSIS (1997 Uniformed Services Dermatology Seminar, Case #30) presented by: Diane Touart, Maj, MC, USA

History: presented after an attempt to lighten his facial skin with an OTC bleaching cream purchased in Germany. Darkening of his cheeks occured after an unspecified duration of use, for which he sought medical help. He was prescribed hydroquinone for the darkening which caused worsening of the condition. The medication was discontinued shortly afterwards. (Specific time frames are difficult to elicit from pt).

Exam: PHYSICAL EXAM: Bilateral malar "sooty" brown-black hyperpigmented patches. HISTOPATHOLOGY: Marked swelling of collagen fibers with deposition of yellow-brown crescent-shaped pigment deposits. Some collagen fractured. Post-laser bx reveals some diminution in crystal size - no decrease in overall amount. No increase in macrophage number.

No MeSH data available.
