Rosettes in T-cell pseudolymphoma: a new dermoscopic finding

Area of Science:

• Dermatology
• Dermoscopy
• Histopathology

Background:

• Rosettes are characteristic white structures observed under polarized light dermoscopy.
• Their precise morphological correlation and diagnostic significance remain incompletely defined.
• These structures have been documented in a diverse range of benign and malignant skin conditions.

Observation:

• This study reports the novel observation of rosettes within a T-cell pseudolymphoma lesion.
• The presence of rosettes in this specific condition was previously undocumented.

Findings:

• The findings establish a new association between rosettes and T-cell pseudolymphoma.
• This expands the differential diagnosis for structures observed with dermoscopy.

Implications:

• This observation may aid in the dermoscopic diagnosis of T-cell pseudolymphoma.
• Further research is warranted to understand the pathognomonic features and diagnostic utility of rosettes in various cutaneous conditions.
