NON-PALPABLE LESIONS OF THE MAMMA - RESUL TS OF SONOGRAPHIC, PREOPERATIVE COLOR MARKING ON THE SKIN

68 nonpalpable und sonographically visible lesions of the mammae were marked preoperatively in 59 patients, The skin over the tumour was col our-marked with the patient in position for operation after sonographi c adjustment, The sonographically measured depth of the lesion and its diameter were noted, All the 68 lesions were completely extirpated in 60 operations, In 91.7% of the operations (55/60) the suspicious focu s was directly identified intraoperatively and excised with an all-aro und safety margin of 1 to 2 cm, In 8.3% (5/60) of the surgical interve ntions it was necessary to re-resect the margin of the resectate due t o invasive growth, After sonographic localisation, occult intramammary lesions cannot be marked on the skin noninvasively and at an economic ally favourable cost for subsequent safe surgical removal.
