Dermal Discoloration Secondary to Triamcinolone Acetonide Injection Observed in Patients with Autoimmune Disorders

Area of Science:

• Dermatology
• Pharmacology
• Internal Medicine

Background:

• Triamcinolone acetonide is a widely used synthetic glucocorticoid for inflammatory conditions.
• Parenteral administration side effects are documented, but rare adverse events require further attention.

Purpose of the Study:

• To raise awareness of a rare, delayed side effect: violaceous dermal pigmentation.
• To document cases of this underreported adverse reaction to triamcinolone acetonide.

Main Methods:

• Case series presentation of three patients experiencing violaceous dermal pigmentation.
• Review of medical literature for similar reported cases.

Main Results:

• Three patients developed violaceous dermal pigmentation following triamcinolone acetonide administration.
• This specific side effect appears to be rarely documented in existing literature.

Conclusions:

• Violaceous dermal pigmentation is a potential, albeit rare, delayed side effect of triamcinolone acetonide.
• Further research is warranted to explore a possible link between this side effect and autoimmune diseases.
