- A case study describes a 68-year-old white man with a 9-year history of a mildly itchy hyperpigmented patch on his nose, ultimately diagnosed as pigmented ALP through histopathological analysis showing characteristic changes.
- Treatment involved topical pimecrolimus and tretinoin, effective in reducing symptoms, while emphasizing the importance of accurate diagnosis and ongoing sun protection to manage and prevent the condition.
The effect of topical tranexamic acid with micro-needling and micro-needling alone in treatment of macular amyloidosis.
J Cosmet Dermatol
December 2024
Skin Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
Article Synopsis
- - The study focused on comparing the effectiveness of combining topical tranexamic acid with micro-needling versus micro-needling alone in treating macular amyloidosis, a skin condition characterized by itchy, pigmented macules.
- - A total of 20 female patients participated, with their skin being treated in two groups over four sessions; results showed improvements in both groups regarding pigmentation and itchiness, but no significant difference was found between the two treatment methods.
- - Ultimately, micro-needling alone was effective in reducing pruritus and pigmentation, while the addition of tranexamic acid did not provide any extra benefits.
