RESUMO
INTRODUCTION: Secondary lesions in the breast from extramammary malignancies are rarely encountered in medical practice. Medical imaging of the breast (mammography and ultrasonography) may not differentiate between a primary breast mass and a secondary tumor from an extramammary malignancy. CASE DESCRIPTION: A 90-year-old woman with a history of thyroid cancer, skin metastasis, thyroidectomy, and radiotherapy 12 years prior presented with pain in the left breast and no palpable masses in either breast or axilla. Mammography and ultrasonography of the breast confirmed a suspicious lesion in the upper outer quadrant of the left breast. Histopathology of the core biopsy, including immune histochemistry staining of the lesion, confirmed secondary follicular carcinoma of the thyroid. CONCLUSION: Thyroid cancer is a rare extramammary malignancy that may metastasize to the breast; however, it may rarely occur a few years after thyroidectomy and radiotherapy.

Phyllodes tumor is uncommon in children, and the malignant form is rare. There have only been a few cases of benign phyllodes tumor reported in peripubertal children and only one malignant case. We report the second case of malignant phyllodes tumor in a premenarchal 11-year-old girl.

Jejunal diverticulosis is rare and often goes unnoticed until complications occur. The diverticula are true, acquired diverticula and often asymptomatic. Jejunal diverticulosis can be associated with diverticulosis of the duodenum, ileum, and colon. Here we describe a patient with known severe diverticular disease of the large bowel, who presented acutely with abdominal pain and signs of generalised peritonitis. Laparotomy showed ruptured jejunal diverticulosis with a single band over the terminal ileum, causing small bowel obstruction. Spontaneous perforation of a jejunal diverticulum is rare and is usually an intraoperative finding. One should exclude a precipitating cause, such as coexisting distal obstruction, stricture, or a foreign body.
