Axillary lumps are common clinical presentations in surgery, which have various differential diagnoses. We encountered an unusual case of an isolated axillary mass. The patient was a young woman in her 20s with a 2 year history of right axillary swelling. Clinically, the lump measured 3 cm ×3 cm, mobile, non-tender, and there was no associated breast lump or skin changes. Our initial impression was an isolated lymphadenopathy, and further workup for tuberculosis lymphadenopathy returned negative. Ultrasound demonstrated a well circumscribed oval lesion, and fine needle aspiration could only identify a benign proliferative breast tissue. As it was increasing in size and causing discomfort, we decided for an excision biopsy for both diagnostic and therapeutic reasons. Intraoperatively, the lump was noted to have well defined, smooth surface along with whitish-grey appearance. The tissue surrounding it was also removed and sent for histopathological assessment. Results confirmed our diagnosis of fibroadenoma in an ectopic breast tissue.

Desmoid fibromatosis is a rare, benign, locally aggressive fibroblastic proliferation that may occur in almost any anatomical location. Due to its rarity and unpredictable clinical course, there has not been a standard guideline of treatment. We encountered a case of desmoid fibromatosis in our centre. A young lady previously fit and well was referred for a symptomatic, rapidly growing left sided abdominal mass. Otherwise, she denied any bowel related symptoms or constitutional manifestation. Imaging demonstrated a large well-defined lobulated solid-cystic mass extending from vertebral level T10 to L5, measuring 10.5 cm × 15 cm × 23 cm. The mass was in close proximity with the left adrenal gland, left kidney, pancreas and spleen. Ultrasound guided biopsy interpreted it as a fibroblastic or myelofibroblastic tumour, favouring desmoid fibromatosis. Surgery was then performed where the mass was removed along with the left adrenal gland and kidney. Post-operative care was complicated with pulmonary embolism, hospital-acquired pneumonia and pancreatitis.
