Resumen

Introduction: Pilomatricoma is a rare, benign skin tumor, with an estimated frequency of 1% among all skin tumors. It primarily affects the head and neck region, particularly in the pediatric population. While multiple pilomatricomas are uncommon and represent 0.7–3% of all cases, recurrent ones are even rarer and require special attention when managing this benign skin tumor. Objective: To report a pediatric case of multiple and recurrent pilomatricomas, emphasizing its clinical characteristics diagnostic challenges, and therapeutic decisions. Clinical Case: A 12-year-old male patient with multiple pilomatricomas since the age of six, who had previously undergone five surgical excisions. Currently, new tumors have emerged on his neck and thigh, steadily increasing in size. The lesions were subcutaneous, mobile, and non-painful, with no associated systemic symptoms or neurological conditions. Pathological examination and soft tissue ultrasonography confirmed the diagnosis of multiple and recurrent pilomatricoma, and a new surgical intervention was scheduled. Conclusion: The patient developed more than seven tumors over a six-year period—a pattern uncommon in published pediatric cohorts. Recognizing the specific characteristics of multiple and recurrent pilomatricomas in pediatric patients is essential for accurate and timely diagnosis.
