Clinical history
18 year-old male presented with one year history of a slow growing mass on the scalp. CT-scan showed a soft tissue tumour infiltrating skull penetrating intracranially ( figure 1). The growth was located in the centre of the parietal region. Excision of the mass, including bone particles was done. The specimen was sent to the Department of Pathology for histological diagnosis.
Two surgical specimens were received at the Department. The smallest was made up of small soft tissue fragments admixed with bone particles; and the tumour itself (no picture of the smallest shown). The macroscopic appearance of the tumoral mass is seen in figures 2 and 3.
Se muestran los resultados de biopsia en un paciente con una masa tumoral de partes blandas del cuero cabelludo, de crecimiento lento, de alrededor de un año de duración, que fué resecada en un varón de 18 años. El tumor era clínicamente blando, no doloroso, fijado al cráneo. La TAC de cráneo mostró infiltración del hueso, con penetración en la cavidad craneana. Se realizó biopsia excisional y se envió para estudio a nuestro departamento. Este trabajo presenta los hallazgos clínico-morfológicos (macro y microscópicos) de la biopsia y se realizan algunas consideraciones acerca de su posible histogénesis.
