Carcinoma right breast in a male

Case contributed by Dr Garth Kruger

Presentation

Palpable, non-tender mass right breast for 3 months

Patient Data

Age: 65 years old
Gender: Male
Modality: Mammography

The MLO views showing the right breast carcinoma.

This ultrasound is from a different patient.

Modality: Ultrasound

This is the typical appearance of gynaecomastia on ultrasound. The nipple is located at the 2 on the image. The triangular orientation with the apex of the triangle abutting the posterior aspect of the nipple is pathognomonic of gynaecomastia. Contrast this image to images of carcinoma breast on ultrasound.

Case Discussion

The differential diagnosis for a breast lesion in a man is always gynaecomastia. 

The mammographic and ultrasound characteristics of male carcinoma breast are exactly the same as those of the cancer in  a female breast. There is no imaging difference between genders. This lesion is mammographically dense, poorly defined and in a female it would always be suggestive of a malignancy.

In practice, the mammogram images of gynaecomastia show the mass-like density abutting the posterior margin of the nipple; note this lesion is a little away from the nipple.

The ultrasound images are always helpful (see above). Always include ultrasound in the workup of the male breast as with females. The typical triangular density of gynaecomastia is a dead giveaway on ultrasound. The apex of the triangular breast tissue abuts the posterior nipple.
