Floret-like multinucleated giant cells in neurofibroma

Area of Science:

• Oncology
• Pathology
• Dermatology

Background:

• Neurofibromas are benign tumors, but rare malignant transformations occur.
• Floret-like multinucleated giant cells are an uncommon finding in soft tissue tumors.
• These cells have been previously observed in gynecomastia and neurofibromas associated with neurofibromatosis type 1.

Purpose of the Study:

• To report a second case of neurofibroma with floret-like multinucleated giant cells.
• To discuss the differential diagnosis and implications of these cells in neurofibromas.

Main Methods:

• Case report and literature review.
• Histopathological examination of the tumor.
• Discussion of immunohistochemistry for cell characterization.

Main Results:

• A case of neurofibroma exhibiting floret-like multinucleated giant cells was identified.
• This finding is rare, with only one prior report in the literature.
• Differential diagnoses include other soft tissue tumors with similar giant cells.

Conclusions:

• Floret-like multinucleated giant cells in neurofibroma are rare but warrant careful evaluation.
• Awareness of these cells is important due to the potential for malignant change in neurofibromas.
• Immunohistochemistry can aid in characterizing these giant cells and confirming the diagnosis.
