gynaecomastia

The occurrence in the male of breasts resembling those of the sexually mature female. Gynaecomastia is often temporary as a result of a transient hormonal upset, but it may be caused by treatment with oestrogens or steroids, by liver disease, by a tumour of the PITUITARY GLAND or the testicle, or by the use of the diuretic drug spironolactone. Persistent gynaecomastia has, traditionally, been treated by plastic surgery, but the preferred treatment now appears to be the drug TAMOXIFEN. From the Greek gynae , a woman and mastos , a woman's breast.
