Appeal from a decision and award of the Workmen’s Compensation Board. Claimant was employed as a spoilage recorder in appellant’s plant; he testified that on April 17, 1956 in attempting to avoid spoilage which he was taking from a basket and placing in a steel truck from falling to the floor, he brought up his left leg to gain balance, and as he did so his left thigh came in contact with the truck. He described two things happening to his thigh: (a) “I grazed it, part of my leg and the outer side of my knee”; and (b) “a severe blow I got on the lower part of my thigh.” He amplified this description in the record: “ It was the lower part of my left thigh, struck this projecting metal from the truck. That was the part I really hit hard.” He described this place of contact as being about four inches above the kneecap. It is made clear in the record that claimant described this heavy blow and the site of the “ scratches ” as being near each other but at different places, on the left thigh. A plant nurse treated him immediately after the accident. She said that she “saw three small cuts that were bleeding slightly 6 - * * on the outer aspect, slightly above the knee.” Ten days later claimant reported to the nurse that “his left thigh was slightly painful and swollen since” the accident and “ then I examined the thigh and it was slightly larger than the right and an area of hardness, no discoloration.” Prior to this accident claimant testified he had had no symptoms or difficulty with his thigh and for the nine years he had been working for employer had exhibited remarkably good health. On the second examination the nurse suggested medical attention, and when on April 30 claimant was examined by a physician it was discovered that there was a large hard mass, four and one-half by six inches in size on the front side
