RESUMO

El pilomatrixoma es un tumor anexial benigno, que muestra diferenciación hacia células matriciales y supramatriciales del folículo piloso. Es el segundo tumor benigno más frecuente en la población infantil luego del quiste epidérmico. Su presentación clínica habitual consiste en una lesión única, de consistencia firme y generalmente indolora.1 La variante anetodérmica o bulosa es poco frecuente, en general de rápido crecimiento y en ocasiones dolorosa.2 Se presenta a continuación un caso clínico de esta rara variante, por la importancia de conocer esta particular forma presentación.


A clinical case of bullous pilomatrixoma is present. Correspond to the second most frequent benign tumor in children, derived from the matrix cells of the hair follicle. It commonly presents as a single lesion, of firm consistency and mostly painless. The bullous variant corresponds to 2% of the presentations, the morphology is explained by the dilation of the lymphatic vessels and the consequent extravasation of lymph, as well as by the absence of elastic and collagen fibers. Treatment is the surgical excision of the lesion, and a biopsy specimen is necessary to establish a definitive diagnosis. Knowing this form of presentation allows us to pose it as a diagnostic option in clinical practice.
