This case study described the diagnosis of a trichofolliculoma in a 56-year-old woman, emphasizing its dermoscopic features and histological aspects that confirmed the tumor type, with no recurrence observed after excision.

Histopathology is crucial for accurately diagnosing eruptive vellus hair cysts.

This case study describes a middle-aged woman diagnosed with a proliferating trichilemmal tumor on her scalp, emphasizing the importance of comprehensive diagnostic approaches and highlighting surgical excision as the primary treatment.
