[PURPURIC MYCOSIS FUNGOIDES]

Area of Science:

• Dermatology
• Oncology

Background:

• Presents a rare case of purpuric mycosis fungoides (MF).
• Discusses the diagnostic challenges in differentiating MF from benign conditions.

Observation:

• A 26-year-old female with a 4-year history of asymptomatic purpuric patches on her left leg.
• Clinical presentation included purpuric patches up to 3 cm on the flexure aspect of the leg.

Findings:

• Histological examination revealed lymphocytic infiltrate with mild atypia.
• Evidence of red blood cell extravasation and hemosiderin deposition in the papillary dermis confirmed the diagnosis.

Implications:

• Emphasizes the importance of recognizing early-stage purpuric mycosis fungoides.
• Underscores the need for clinicians to differentiate this rare MF variant from benign pigmented purpuric dermatoses to ensure appropriate patient management.
