Özet

Background and Design: Pilomatrixoma calcifying epithelioma of Malherbe is a rare, benign, limited, calcifying epithelial neoplasm that arises from the hair pluripotent precursor matrix cells. It is usually seen in the head and neck and the upper extremities, in the dermis or subcutaneous tissues as an asymptomatic nodule. In this study, we discuss the epidemiology of the tumor, clinical and histopathological findings, differential diagnosis and treatment outcome of pilomatrixoma in the light of our experiences with 20 cases. Materials and Methods: We retrospectively evaluated a total of 20 cases diagnosed with pilomatrixoma with a pathology evaluation after excisional biopsy of the subcutaneous mass at pediatric surgery clinics between 2005 and 2012. Results: Our 20 patients consisted of 12 females (60%) and 8 males (40%). The mean age at the time of diagnosis was 9.6 years. There was a single nodule in 18 cases (90%) and two nodules in separate places in 2 cases (10%). The tumor localization was in the head and neck in 54.5%, the extremities in 31.8%, and the trunk in 13.6%. Conclusion: Pilomatrixomas are rare but usually seen in children and adolescents and this benign skin tumor can be treated with surgical excision. Histopathological and clinical features should be evaluated carefully to prevent missing the malignant form that carries a risk of recurrence and even metastasis.
