Variants of dermatofibroma--a histopathological study

Area of Science:

• Dermatology
• Pathology
• Oncology

Background:

• Dermatofibromas exhibit diverse clinical and histopathological presentations.
• Understanding these variants is crucial for accurate diagnosis and patient management.

Purpose of the Study:

• To review the main clinical and histopathological features of dermatofibroma variants.
• To aid in the differential diagnosis and prognosis of these skin lesions.

Main Methods:

• Retrospective study of skin biopsies and tissue excisions.
• Analysis of 192 dermatofibromas diagnosed between May 2007 and April 2012.
• Focus on clinical presentation, histopathological characteristics, differential diagnosis, and prognosis.

Main Results:

• 192 dermatofibromas were diagnosed in 181 patients (predominantly women, median age 48).
• Most common site was the limbs (74%).
• Histopathological types included common fibrous histiocytoma (80%) and variants like aneurysmal, hemosiderotic, epithelioid, cellular, lipidized, atrophic, and clear cell.

Conclusions:

• Dermatofibroma variants present with distinct clinical and histological features.
• Accurate identification of variants aids in appropriate differential diagnosis and prognosis.
• This review provides a comprehensive overview of dermatofibroma subtypes.
