RESUMO
It is recommended that mucocele-like lesions be excised to enable differentiation between benign lesions and carcinoma. In addition, ductal carcinoma in situ may be found in close association. A small series of 12 lesions audited at BreastScreen Auckland has shown six benign, one atypical, and five malignant lesions. Although this is a small series, a high rate of associated malignancy has been reported.

Metaplastic breast carcinoma is uncommon and constitutes less than 5% of all breast cancers. The cancerous epithelium becomes non-glandular through metaplastic differentiation. There are various subtypes and the extent to which this process occurs varies. A case of a 52-year-old female patient is reported and the published literature is reviewed.

Stereotactic biopsy has become a widely used technique for marnmographically detected lesions that are clinically and sonographically occult. Vacuum-assisted (mammotome) biopsy on a dedicated prone stereotactic unit has further increased ease of biopsy and utility of the technique. Results of an 18-month audit in the national breast screening programme (BreastScreen Auckland and North) in the Auckland region demonstrates results comparable with those achieved elsewhere. Of a total of 399 stereotactic biopsies, 23 were excluded as they were 14-G core biopsies rather than 11-G mammotome biopsies. Of 376 mammotome biopsies, 10 (2%) failed, 266 (70.7%) were benign, 39 (10.3%) were atypical ductal hyperplasia (ADH) and 70 (18.6%) were malignant. Of these, 14.6% were ductal carcinoma in situ (DCIS) and 4% were invasive carcinomas. All cases diagnosed as ADH underwent formal excision biopsy. Of the 39 cases, 33 demonstrated benign disease or residual ADH only on excision (84.6%) and six (15.4%) patients were upgraded: five to DCIS and one to invasive carcinoma. The significant complication rate was 0.5%. Indications for biopsy were calcification in 89% of cases, mass lesions in 10.6% of cases and architectural distortion in 0.2% of cases. The failure rate of 2% compares with hookwire biopsy series. Practical issues and protocols have been presented.

Aggressive fibromatosis is a rare, locally aggressive disease. It constitutes 0.3% of all solid tumors, but the tumor is rarely seen in the breast, particularly without pectoral muscle and fascial involvement. The etiology is unknown, but an association with Gardner's syndrome has been described. Clinical and imaging findings simulate breast carcinoma. A case in a 53-year-old female patient is reported.
