Light sensitivity in mycosis fungoides

|September 1, 1977
Summary
Patients with mycosis fungoides may experience photosensitivity. Phototesting revealed abnormal skin reactions to UVA, UVB, and visible light in several individuals, particularly in later disease stages.
Area of Science:
- Dermatology
- Photobiology
Background:
- Mycosis fungoides is a type of cutaneous T-cell lymphoma.
- Photosensitivity is a suspected complication in some mycosis fungoides patients.
Purpose of the Study:
- To investigate photosensitivity in patients with mycosis fungoides.
- To identify specific light wavebands that trigger adverse reactions.
Main Methods:
- Phototesting was performed on twelve patients diagnosed with mycosis fungoides.
- Patients were exposed to various ultraviolet (UVA, UVB) and visible light wavebands.
Main Results:
- Four patients reported burning and erythema after sun exposure, primarily in stage II.
- Abnormal reactions to phototesting were observed in 7 out of 12 patients.
- The most common triggering wavebands were in the UVA range, followed by UVB and visible light.
Conclusions:
- Mycosis fungoides patients can exhibit significant photosensitivity.
- UVA, UVB, and visible light can induce adverse skin reactions in affected individuals.
- Phototesting is a valuable tool for assessing photosensitivity in mycosis fungoides.
