巨大子宮頸部筋腫の1例

Patient is 40 years old with history of two deliveries and the last delivery was at the age of 28 years, but she had no irregularity with mestruation. Her chief complaint was a hypogastric tumor. On examination at our clinic we found: the size of corpus uteri, about normal; felt an immovable, soft but solid tumor as large as a head of adult in the hypogastric region; and it was diagnosed as a intraligamentary solid tumor of ovary. Upon laparotomy we found no abnormalities in both adnexa and corpus uteri itself, but with the progress of operation we uncovered a giant myoma of the uterine cervix, measuring 19cm×25cm×20cm, and weighting 3.2kg, which grew out of the right wall fo the uterine cervix with the pedicle as big as the size of a pencil. Myomectomy and subtotal hysterectomy was performed. It is generally accepted that the cervical myoma of uterus is relatively rare, occupying only about 5 per cent of all uterine myomas. Furthermore, with a better understanding for surgery on the part of general public, the incidence of giant myoma of the uterine cervix has become still rarer. As for the symptoms when such a tumor reaches beyond a certain size, increased frequency of urination and corstipation are said to occur. Fortunately no such symptoms could be observed in the present case, and just as in this case, such a myoma is quite difficult to differentiate from the solid tumor of ovary and it is only after operation that it can be diagnosed correctly as a myoma of the uterine cervix. As for the relationship between the pregnancy and the delivery, it is generally the same as in the case of other uterine myoma. For the cure of such a case surgery is the sole therapeutic measure.
