Abstract
OBJECTIVE: To describe our experience with pilomatrixomas, clinical presentation, clinical accuracy, associated diseases, and surgical treatment.
METHODS: A retrospective review of patients with a pathology report of an excised pilomatrixoma between 2011 and 2014. Data regarding gender, age of intervention, number of masses, size, location, and preoperative clinical diagnosis, pathology report, recurrences, and associated diseases were collected. Statistical analysis was performed using EPIinfo 7.1.5.
RESULTS: A total of 151 tumors in 138 patients were removed, 25 were excluded for having a clinical diagnosis of pilomatrixoma without confirmation of the pathology report. The remaining 126 cases have an average age of 8.26 years (range 1-14 years) and 50.72% are males. The tumors were located above the umbilicus in 97% of the cases, with a higher concentration of 50.72% in the head and neck. The clinical diagnosis corresponds with the pathology report in 69.05% of cases. Out of these confirmed cases the most frequent differential diagnosis is cystic lesion (11.90%) and dermoid cyst (10.22%). There were no cases of malignant degeneration. The average diameter is 1.13 cm, there were no recurrences, but there were 11 cases of a new lesion in a different location. There is no statistical association with other pathologies. The most frequent diseases found were obesity (3.62%) and attention deficit syndrome (3.62%).
CONCLUSION: The pilomatrixoma is a tumor that appears predominantly in the head and neck, and has a difficult clinical diagnosis. Complete removal is curative, although it does not prevent the appearance of new lesions.
