Ossifying Pilomatrixoma with Marrow Formation of the Left Cheek Region: Case Report with Literature Review

The document described a case of ossifying pilomatrixoma with marrow formation in a 15-year-old female, presenting as a hard swelling on the left cheek. This rare benign tumor, originating from hair follicle cells, was confirmed through histopathological examination showing unusual ossification and marrow formation. Surgical excision was performed without affecting facial nerve function, and the patient had an uneventful recovery with no recurrence after 1 year. The case emphasized the diagnostic challenges due to the tumor's rarity and the necessity of complete excision to prevent recurrence. The literature review noted a higher prevalence of pilomatrixoma in females, particularly in the head and neck region, and stressed the importance of histopathological confirmation for accurate diagnosis.
