Hypopigmented mycosis fungoides: case reports and literature review
1The Skin Oncology Program, Department of Dermatology, Boston University School of Medicine, Boston, Massachusetts, USA.
Background:
Hypopigmented mycosis fungoides is a rare variant of mycosis fungoides (MF) that usually has a predilection for young individuals with dark complexion.
Objective:
The aim is to describe new cases of hypopigmented MF with confirmed T-cell receptor gene rearrangement analysis.
Methods:
This article includes case reports and a literature review.
Results:
Three out of four hypopigmented MF patients had a positive TCR gene rearrangement. A fifth patient is reported who had hypopigmented mycosis fungoides and classical Pautrier microabscesses, for whom no TCR gene rearrangement analysis was performed.
Conclusion:
Although hypopigmented MF has a predilection for dark-complexioned populations, it can also affect Caucasian patients. In challenging cases, polymerase chain reaction can be a useful method for detecting early cases of hypopigmented MF.
