Abstract

Mammography is an imaging modality that is widely perceived to be of use only in women for the detection and diagnosis of breast pathologies. Here, we present a pictorial essay on the mammographic spectrum of male breast pathologies.

 Introduction



Mammography is a sensitive and cost-effective imaging modality in women. It is carried out for screening and for diagnostic purposes. The low incidence of breast cancer in males does not warrant screening mammography and, therefore, mammography in males is a diagnostic study. [1],[2],[3] Patients with complaints of breast enlargement, tenderness or lump are referred for mammography.

Gynecomastia is the most common cause of breast enlargement. Patients with breast cancer present with a lump rather than breast enlargement. It is critical to distinguish between these two pathologies and mammography has been shown to be a useful imaging modality for the same. [4],[5],[6]

 Discussion



The normal male breast consists of subcutaneous fat and remnant subareolar ductal tissue [Figure 1]. Lobular development is not seen; hence, lobular processes like lobular carcinoma, adenosis and fibrocystic changes are not seen in males. Here, we discuss the mammographic features of breast pathologies seen in males.

Gynecomastia

Gynecomastia is the most common cause of male breast enlargement and is usually bilateral. Patients may however present with unilateral breast enlargement or tenderness. Gynecomastia is characterized by hyperplasia of the stromal and ductal elements in the breast. Clinically, the breast is enlarged, soft and tender and a mass may be palpable in the retro-areolar region. On mammography, gynecomastia can be nodular, dendritic or diffuse. [2],[3],[4] Dendritic gynecomastia appears as 'flame-shaped' fibroglandular tissue in the retro-areolar area, which radiates from the nipple into the deeper adipose tissue [Figure 2]. It is thought to be a result of long-standing gynecomastia. It is histologically characterized by ductal proliferation, with surrounding fibrotic stroma. In nodular gynecomastia, a nodular, mass-like lesion is seen in the retro-areolar region [Figure 3]. In diffuse gynecomastia, the mammographic appearance is that of a dense breast. There is enlargement of the breast with diffuse density and both dendritic and nodular features may be seen. Absence of a well-defined identifiable mass and the secondary signs differentiate gynecomastia from malignancy.

Pseudogynecomastia

In true gynecomastia there is involvement of the breast tissue. Male breast enlargement, as a result of accumulation of excessive fat tissue with a lack of actual breast tissue, is pseudogynecomastia [Figure 4]. This condition is common in older men and overweight young men.

Retro-areolar abscess

On mammography, a retro-areolar abscess appears as a mass with indistinct margins [Figure 5]. There is thickening of the skin. The lesion can be mistaken for carcinoma breast.

Epidermal inclusion cyst

An epidermal inclusion cyst arises from an obstructed hair follicle. On mammogram, there is a well-defined lesion, which is continuous with the skin [Figure 6].

Tuberculosis

As in women, it is very difficult to differentiate breast tuberculosis from carcinoma breast, both clinically and radiologically. An ill-defined mass may be seen on mammography [Figure 7]. Diagnosis can only be made on fine needle aspiration biopsy.

Breast cancer

Male breast cancer accounts for [5],[6] The most common presentation is as a palpable mass. Because there is a paucity of parenchyma as compared with the female breast, the malignancy rapidly progresses to the next stage, with the appearance of secondary signs like nipple retraction, fixation to deeper tissues, skin ulceration or adenopathy.

On mammography, the mass is placed eccentrically. The margins of the lesions can be well circumscribed, lobulated or spiculated [Figure 8],[Figure 9]. Secondary signs may be seen [Figure 10].

To conclude, the majority of male breast lesions are benign. Differentiation between benign and malignant masses is critical. Mammography has been shown to be an accurate method for distinguishing benign gynecomastia from carcinoma breast. Absence of a well-defined mass and secondary signs favor the diagnosis of gynecomastia, whereas an eccentrically located mass, the presence of secondary features and advanced age of the patient suggest carcinoma breast.
