Abstract
in English, Spanish

A pilomatrixoma is a benign skin tumor common in children, which develops from the matrix cells of hair follicles. It presents as a nodule or tumor of approximately 0.5-3 cm in size, with calcium-like consistency, faceted edges, and blue erythematous overlying skin. Sometimes, the skin may atrophy and look like a blister or even extrude calcium. Diagnosis is suspected based on the typical clinical presentation and supplementary imaging tests. The definite diagnosis is made according to histological findings. Surgical removal is the treatment of choice. Here we describe the epidemiological and clinical data, supplementary tests, and surgical techniques in relation to 149 pilomatrixomas resected in 137 patients treated at the Departments of Dermatology of two children's hospitals: Dr. Pedro de Elizalde and Prof. Dr. Juan P. Garrahan.

El pilomatrixoma es un tumor benigno cutáneo, de frecuente aparición en los niños, que se origina en las células de la matriz del folículo piloso. Se presenta como un nódulo o tumor, aproximadamente, de 0,5 a 3 cm de tamaño, de consistencia cálcica, de bordes facetados, con piel suprayacente eritematoazulada. En ocasiones, la piel puede atrofiarse, dar la apariencia de una ampolla e, incluso, extruir material cálcico. El diagnóstico se sospecha por la presentación clínica característica y los estudios de imágenes complementarios. El diagnóstico definitivo es por los hallazgos histológicos. La extirpación quirúrgica es el tratamiento de elección. Se presentan los datos epidemiológicos, clínicos, estudios complementarios y técnicas quirúrgicas empleadas de 149 pilomatrixomas resecados en 137 pacientes tratados en los Servicios de Dermatología de los hospitales de pediatría Dr. Pedro de Elizalde y Prof. Dr. Juan P. Garrahan.
