Breast abscess is a common clinical condition mostly caused by Staphylococcus aureus. However, infections due to mixed organisms are observed in non-lactational women, mostly in smokers. Salmonella infection causing breast abscess is extremely rare in developed countries. We report a case of Salmonella enterica subsp enterica (I) serovar Enteritidis breast abscess in a 48-year-old woman, a UK citizen, who had recently travelled abroad. She was treated successfully with a combination of surgery and ciprofloxacin. Unusual causative organisms should be kept in mind in patients with recent travel abroad and pus should be sent for microbiology. Mastitis caused by Salmonella spp can present with a severely indurated area that may take a few weeks to resolve. Complete assessment with biopsy of the indurated area and breast imaging is mandatory to exclude malignancy.

Carcinomas of primary accessory breast tissue are rare, comprising 0.3–0.6% of all breast cancers and occur most commonly in the axilla. We report the unusual case of a 50-year-old lady with mucinous adenocarcinoma of axillary accessory breast tissue. In this report we review the presentation, key investigations and treatment of this condition.

Giant juvenile fibroadenomas form 1-8% of breast lesions in the adolescent population. We report a case of giant fibroadenoma in a 17-year-old girl who underwent simple lump excision through a lateral breast fold incision followed by lipomodelling to correct the dimpling of the breast. With this dual approach, excellent cosmetic outcome can be achieved for average-sized giant fibroadenoma without the need for more complex technique.

A glomus tumour is a benign mesenchymal tumour. It is extremely rare in the breast. We report a case of glomus tumour of the nipple in a 54-year-old man. To the best of the authors' knowledge, this is the first case report of a glomus tumour of the nipple. We describe the different presenting symptoms, method of diagnosis and treatment.
