Hand Pilomatrixoma: A Rare Localization

This case report describes a twenty-year-old woman misdiagnosed with a sebaceous cyst that was actually pilomatrixoma, a benign skin lesion from hair matrix cells, confirmed by histopathology after excision.

This study presented an elderly male with a nodular lesion diagnosed as pilomatricoma and discussed the value of diagnostic tools like dermoscopy and high-frequency ultrasonography, encouraging clinicians to consider pilomatricoma in differential diagnoses of nodular lesions across all ages.

This study reviewed the literature on pilomatrix carcinoma and reported that while wide local excision was the most definitive treatment, local recurrences and metastases were common.

In this case report, a 27-year-old woman with a swelling on her neck was initially misdiagnosed with squamous cell carcinoma, but was later identified as having pilomatrix carcinoma with lymph node metastasis, highlighting the importance of accurate diagnosis for effective treatment and prognosis improvement.

In this case study, a 34-year-old woman with a rare presentation of pilomatrixoma involving alopecia and skin hypopigmentation showed no improvement in these symptoms despite a 3-month trial of topical steroid treatment, highlighting a potential association between pilomatrixoma and microinflammation.
