[Phyllodes tumour: a rare, rapidly growing breast tumour]. / Phyllodestumor: zeldzame, snelgroeiende mammatumor.

A 40-year-old woman presented at the breast outpatient clinic with a giant tumour of her left breast. The size, rapid growth and radiological characteristics of the lesion led us to suspect a phyllodes tumour. A histological examination of a needle biopsy confirmed this diagnosis. An additional CT scan revealed no signs of metastases. We performed a mastectomy during which a tumour measuring 48 x 33 x 25 cm was resected. Histological examination revealed a borderline phyllodes tumour. Phyllodes tumours are rare fibroepithelial neoplasms of the breast and pre-operatively these are often difficult to differentiate from fibroadenomas. Phyllodes tumours have a variable clinical course with the ability to metastasize and a propensity to recur locally. Complete excision with wide margins is essential to prevent local recurrence. In our case, the surgical margins were limited and our patient was therefore treated with postoperative radiation therapy.

Small bowel diverticulitis as a cause of acute abdomen.

Small bowel diverticulitis is rare and there are no known guidelines for treatment. We present three cases, in which a laparotomy was performed twice and one in which conservative treatment was applied. Clinical presentations were of acute abdomen, one of which initially thought to be a ruptured aneurysm. Computed tomography scanning was the imaging modality used to make an accurate diagnosis in one case. Treatment was either by means of surgery or conservative treatment with antibiotics, bowel rest and parenteral alimentation. The possibility of conservative treatment, in the absence of perforation, is discussed.
