The management of nonpalpable, well-defined breast nodules by short-interval, 6-month follow-up mammography is widely accepted. We have, however, been managing these type of lesions with fine-needle aspiration biopsy (FNAB), guided by sonography or stereotaxic approach, in order to reduce the number of follow-up mammograms. We recommended surgical biopsy only in cases with malignant or suspicious cytology. Patients with benign cytology or inadequate sample were included in a 12-month-interval mammography surveillance program. In the series we present, two carcinomas were diagnosed among 145 lesions (1.38 %). Both had shown malignancy in FNAB. Another two cases, suspicious of malignancy in FNAB, finally resulted benign in histology. The remaining 141 nodules, monitored for at least 2 years, or surgically removed at the patient's request, have not shown signs of malignancy, regardless of a diagnosis of either benign or inadequate sample in FNAB. Sensitivity and negative predictive value of FNAB have therefore been 100 % in this series. No notable differences were observed between stereotaxic and sonographic guidance, except the percentage of inadequate samples (20.3 % by sonography; 25.9 % by stereotaxic sampling). We conclude that stereotaxic or sonographic FNAB is a very accurate diagnostic method in lesions of this type, allowing long-interval surveillance of the nodules with nonsuspicious cytological results.

Steatocystoma multiplex (SM) is a rare inherited cutaneous disorder characterised by multiple subcutaneous oil cysts. We present the radiological features of this uncommon condition in a case report. Numerous lucent, well-circumscribed, smooth-walled nodules appeared in both breasts at mammography. Many lipid-containing intradermal cysts of different sizes were also observed at sonography, scattered over both breasts, axillae, sternal region and abdomen. SM was suspected and no further evaluations were made.

We report a case of Klippel-Trenaunay syndrome which was suggested by microcalcifications detected on routine mammograms. Based on mammographic findings subcutaneous localization was suspected and a skin with subcutaneous cellular tissue biopsy was performed, confirming the microcalcifications at this level. The anatomopathologic report consisted of increase in vascularization in the subcutaneous adipose tissue due to capillary and small-venule proliferation, with intramural calcium deposits.
