Dermatofibroma with monster cells, characterized by large atypical cells, is a distinct histopathological finding. Differentiating these benign lesions from malignant tumors is crucial for accurate diagnosis.

Area of Science:

  • Dermatopathology
  • Histopathology
  • Oncology

Background:

  • Dermatofibromas are common skin tumors.
  • Atypical cells, termed 'monster cells,' can be present in dermatofibromas.
  • Distinguishing benign from malignant lesions is critical.

Purpose of the Study:

  • To report on dermatofibromas associated with monster cells.
  • To highlight key histopathological features.
  • To provide criteria for differentiating from malignant neoplasms.

Main Methods:

  • Histopathological examination of 19 dermatofibroma cases with monster cells.
  • Clinical diagnosis correlation.
  • Comparative analysis with cutaneous malignant fibrous histiocytoma and radiation sarcoma.

Main Results:

  • Nineteen cases of dermatofibroma with monster cells were identified.
  • Monster cells exhibit large, atypical nuclei.
  • Lesions predominantly occurred on extremities.
  • Mitotic figures were rare and not atypical.
  • Architectural pattern is key for differentiation.

Conclusions:

  • Dermatofibroma with monster cells is a variant of benign dermatofibroma.
  • Distinguishing from malignant fibrous histiocytoma and radiation sarcoma relies on architectural features.
  • Accurate histopathological assessment is vital for correct diagnosis and patient management.
