[A case of squamous cell carcinoma of the breast in a patient with Crohn's disease taking azathioprine].

Azathioprine (AZA) treatment in transplant or autoimmune patients and subsequent appearance squamous cell carcinomas at various sites, particularly skin and cervix, has shown a close relationship. However, it remains uncertain whether this is true for the patients with Crohn's disease. We report a case of squamous cell carcinoma of the breast occurred in a 35-year-old female with Crohn's disease taking AZA.

The implication of hot spots on bone scans within the irradiated field of breast cancer patients treated with mastectomy followed by radiotherapy.

Objective: To analyze the implication of abnormal hot spots in the irradiated field of patients treated with mastectomy followed by radiotherapy for breast cancer.

Methods: We reviewed 1842 consecutive bone scans performed on 292 patients treated with a modified radical mastectomy and followed by radiotherapy. If abnormal hot spots at the irradiated sites were detected in the bone scans, we evaluated further studies to determine whether bone metastases were present.
