Recurrent complications of PAAG implants during lactation.

A 35-year-old lactating woman with pre-existing polyacrylamide gel (PAAG) implants for 10 years presented on numerous occasions following both her pregnancies with bilateral recurrent breast infection, pain and finally massive breast enlargement with a ruptured galactocoele necessitating surgical intervention. As the safety of PAAG for the breastfeeding baby is not known, breastfeeding with PAAG implants is not recommended.

A spontaneously resolving breast lesion: imaging and cytological findings of nodular fasciitis of the breast with FISH showing USP6 gene rearrangement.

We report a case of nodular fasciitis of the breast in a 48-year-old woman who presented with a tender rapidly growing right breast lump. Ultrasound guided fine needle aspiration (FNA) of the solid mass was performed. Cytology was reported as atypical spindle cell neoplasm and the patient was referred to a breast surgeon at a tertiary institution for a definitive diagnosis and further management.

Pseudoangiomatous stromal hyperplasia causing massive breast enlargement.

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a benign mesenchymal proliferative process, initially described by Vuitch et al. We report an unusual case of a 46-year-old woman who presented with a 6-week history of bilateral massive, asymmetrical, painful enlargement of her breasts, without a history of trauma. On clinical examination, both breasts were markedly enlarged and oedematous, but there were no discrete palpable masses.

The disappearing clip: an unusual complication in MRI biopsy.

MRI-guided biopsies are being increasingly used for otherwise occult breast lesions. Clip migration has been reported however, to the best of our knowledge, there have been no documented cases of entire disappearance of a marker clip. Absence of the postbiopsy marker clip was noted when our patient returned for preoperative hook-wire localisation even though accurate clip placement had been confirmed on the post-MRI biopsy mammogram.

Radioactive seed localisation to guide removal of impalpable lymph nodes (radioguided occult lesion localisation using iodine-125 seeds, "ROLLIS").

Two patients with cancer requiring removal of specific impalpable lymph nodes for full pathological analysis underwent ultrasound-guided lesion localisation and marking with a low-activity I-125 seed. A gamma probe was used in theatre to localise the signal from the seed and guide excision. Successful removal of the lesions was confirmed with the probe and by specimen radiography.
