Pilomatrixoma mimicking breast carcinoma

Area of Science:

• Dermatopathology
• Oncology

Background:

• Pilomatrixoma is a benign skin appendage tumor typically found in head and neck regions.
• Breast pilomatrixoma is exceptionally rare, especially in males.

Observation:

• A middle-aged male presented with a breast mass initially suspected as breast carcinoma.
• Clinical and imaging findings were atypical for a pilomatrixoma.

Findings:

• Histopathological examination confirmed the diagnosis of pilomatrixoma.
• The tumor exhibited unusual clinical characteristics for pilomatrixoma.

Implications:

• This case underscores the importance of considering rare differential diagnoses in breast lesions.
• Awareness of pilomatrixoma's varied presentations is crucial for accurate clinical diagnosis and management.
