[Diseases of the male breast]

The authors analyzed the histories of 164 men with diseases of the mammary gland, examined in 1976 to 1986 in a clinic for breast diseases. Mastopathy was diagnosed most frequently (114 times), followed by mastodynia, mastitis and benign and malignant tumours. Seventy patients with histologically benign tumours were operated, a malignant tumour was revealed on biopsy seven times. Attention is drawn to hormonal factors in puberty and old age. The necessity to pay attention also to the male breast is emphasized.
