Objetivo

Estudiar las características ecográficas de diversos tumores de la piel.

Materiales y Métodos

Desde junio de 2000 a mayo de 2001 se harealizado ecografía con transductor circular arrayde 10 MHz a 53 pa-cientes con tumores de piel. En cada lesión se analizaron las siguientescaracterísticas ecográficas: forma, tamaño, delimitación de bordes, re-laciones de vecindad y ecoestructura (ecogenicidad, homogeneidad yconducción del sonido).

Resultados

Se han estudiado cinco nevus epidérmicos, dos quistesepidérmicos, seis carcinomas de células basales, cinco carcinomas es-pinocelulares, diez quistes sebáceos, un linfangioma, cinco hemangio-mas, seis histiocitomas fibrosos benignos, tres dermatofibrosarcomasprotuberans, dos neurofibromas plexiformes, cuatro lipomas, un nevusmelanocítico y tres melanomas malignos.

Conclusiones

Se describen las características ecográficas de distintos tumores dermatológicos. Es fundamental el uso de sondas de altafrecuencia para estudiar la epidermis. La ecografía permite realizar unestudio de extensión de la lesión, especialmente útil en los casos demelanoma.

Objective

To study the ultrasonographic features associated withdifferent skin tumors.

Material and methods

Between June 2000 and May 2001, ultrasound studies using a 10MHz-circular array transducer were perfor-med in 53 patients with skin tumors. Each lesion was analyzed to assess the following ultrasonographic features: shape, size, margins,neighborhood relations and ultrastructure (echogenicity, homogeneityand ultrasound conduction).

Results

The lesions studied included 5 epidermal nevi, 2 epidermal cysts, 6 basal cell carcinomas, 5 spindle cell carcinomas, 10 sebaceous cysts, 1 lymphangioma, 5 hemangiomas, 6 benign fibrous histiocytomas, 3 cases of dermatofibrosarcoma protuberans, 2 plexiformneurofibromas, 4 lipomas, 1 melanocytic nevus and 3 malignant me-lanomas.

Conclusions

The ultrasonographic features of different skin tumorsare described. The use of high-frequency probes is indispensable in thestudy of the epidermis. Ultrasound allows the determination of the ex-tension of the lesion, a feature that is especially useful in cases of melanoma.
