From 1955 through 1970 the transition of filarial symptomatic patients in a town of Bonotsu, located on the southernmost part of Satsuma peninsular, Kagoshima prefecture, had been investigated. The investigations showed that number of hydrocele and chyluria patients had a tendency of decrease, though new such cases occurred at times. New cases of elephantiasis were not found as far as our investigations were concerned and the number of the disease reduced by half in ten years. A case of huge elephantiasis of the scrotum and the penis we saw lately is described. The patient is a male, 44 years old, who lives in Tokunoshima, Oshima-gun, Kagoshima prefecture. The first filarial fever attack was noticed when he was 14 years old and since then the attack would usually occur after labor once or twice a month. The patient's penis had started to increase in size gradually when he was 17 years old and at 34 it grew as low as his knee joints. Afterwards the patient's penis has grown as long as his legs without being accompanied by episodes of fever attacks or chyluria. The patient's waist is 66.3 cm (circumference) and the largest part of the scrotum 76.8 cm (circumference), which shows the scrotum is larger than the patient's waist by more than 10.0 cm. The length of the penis is 58.0 cm; the smallest part, coronary sulcus, 43.5 cm. A circumference of the glans penis is 50.5 cm. Total weight of the penis and the scrotum amounts to about 18.5 kg, which forms one-third the body weight, in contrast with the patient's height (142.0 cm) and body weight (52.6 kg). We report scrotal elephantiasis which is accompanied by penile elephantiasis, that is thought to be very rare.
