A case report of pseudoaneurysm after a core needle biopsy of breast cancer.

Breast pseudoaneurysms after a core needle biopsy are a rare complication with a low incidence. However, it is important to be aware of the possibility of complications that require treatment.

[Approach to cytologically-benign recurrent thyroid cysts]. / Actitud ante los quistes tiroideos recidivantes con citología benigna.

INTRODUCTION: The aim of this study was to determine the incidence of carcinoma in cytologically-benign recurrent thyroid cysts and to evaluate the surgical indications in these patients. PATIENTS AND METHOD: We reviewed all patients undergoing thyroid surgery between January 1992 and December 2002 for cytologically-benign solitary or dominant cystic nodules in multinodular goiter that recurred after aspiration. Mixed nodules were excluded. RESULTS: Thirty-four patients (29 women and five men) with a mean age of 43 years (18-76) underwent surgery. Seventy-five percent were solitary nodules and 25% were dominant nodules within a multinodular goiter. The mean number of fine needle aspirations with complete drainage was 2.3 (2-3) per patient with hemorrhagic aspirate in 35%. Total thyroidectomy was performed in multinodular goiters and lobectomy with isthmectomy in solitary nodules. Intraoperative biopsy revealed benign lesions in 91% and was inconclusive in the remainder; no cases of carcinoma were identified. Definitive pathologic findings revealed the nodule to be a papillary carcinoma in 3 patients (8.8%) and occult papillary carcinoma separate from the cyst in 4 patients (11.8%). In all these patients intraoperative biopsy showed benign disease. The risk of malignancy was higher in cysts larger than 3 cm (23% vs 0%; p<0.05). CONCLUSIONS: Given the incidence of carcinoma, surgical resection should be considered in recurrent cystic thyroid nodules, especially in those larger than 3 cm, regardless cytological study.
