Twenty feline neoplasms were sequenced in the region from exons 5 to 8 for the presence of tumour suppressor gene p53 mutations. In a spindle cell sarcoma of the bladder, a missense mutation (codon 164 AAG-->GAG, lysine-->glutamic acid) in exon 5 was detected. In a pleomorphic sarcoma, a 23 bp deletion involving the splicing junction between intron 5 and exon 6 was observed. In a fibrosarcoma, a 6 bp deletion of p53 covering 2 bp of exon 7 and 4 bp of intron 7, including the splicing junction, was found. The study demonstrates three new p53 mutations in different types of sarcomas in cats.

We describe a patient who underwent thoracic radiation therapy for biopsy-proven pulmonary spindle cell sarcoma in the left lower lobe, 15 months after birth. At the age of 37 she developed shoulder pain, fatigue, and progressive exertion dyspnoea. Chest X-ray revealed a pulmonary mass in the left lower lobe due to a cytology-proven malignant tumour.The patient underwent left pneumonectomy. Histology revealed a myosarcoma of the lung, similar to the previous sarcoma. Furthermore, the patient was diagnosed to have Turner syndrome mosaic and chromosomal analysis revealed a translocation t(1;13) in 3/50 metaphases. However a germline mutation of the p53 tumour suppressor gene was excluded. After 2 years of follow-up the patient is stable and there are no signs of recurrence of the tumour.We conclude a re-occurrence of this very rare malignant disorder of the lung after a 36-year interval in a patient with Turner syndrome mosaic. Following initial curative radiation therapy, with a remission over 36 years, lung resection was now successfully performed.
