Male breast cancer and gynecomastia are uncommon but important conditions to evaluate in men. Male breast cancer makes up about 1% of all breast cancers and usually presents as a hard, fixed, painless mass in the breast. Gynecomastia is a benign condition characterized by enlargement of breast tissue and can be caused by increased estrogen or decreased testosterone. Mammography is useful for evaluating suspicious breast lesions in men, with cancer appearing as spiculated or ill-defined masses and gynecomastia appearing as nodular or dendritic densities. Biopsy is needed to confirm a diagnosis of breast cancer in men.
2. Introduction to male breast tumor..
Male breast carcinoma is a
rare disease
< 1% of all malignancies in men
1% of all breast cancers
3. Introduction to male breast
tumor:
BREAST TUMOR IN MALES
Testicular tumor such as leydig cell tumors or sertoli
cell tumor such as (peutz Jeghers syndrome) or human
chorionic gonadotropin (Hcg) secreting
choriocarcinoma may result in gynecomastia. Other
tumors such adrenocortical tumors,pituitary gland
tumors (such as, prolactinoma) or broncchogenic
carcinoma, can produce hormones that alter male
female hormone balance and cause gynecomastia.
4. Introduction to male breast tumor:
Clinically suspicious lesions
Imaging evaluation
Mammography
In patients with questionable findings at
mammography and for lesions that are difficult to
image with mammography
The relationship of the mass to the nipple should be
carefully assessed
an eccentric location is highly suspicious for
cancer.
5. The breast tissues of both sexes are
identical at birth
Estrogen stimulates breast tissue
Androgen antagonizes these effects
At puberty in boys - increase in
estrogen,testosterone
Transient proliferation of the ducts and
stroma
Followed by involution and ultimate atrophy of
the ducts.
Breast Development
6. Normal Male Breast
Characterized:
Subcutaneous fat
Remnant of
subareolar ductal
tissue
Lobular development -
which requires both
estrogen and
progesterone, is usually
not observed in men
7. Normal Male Breast
Anatomy of the normal male breast- consists of the skin
and subcutaneous fat. The pectoralis fascia (PF),
pectoralis muscle (PM), ribs,and intercostal muscles
(ICM)
8. Introduction
The two most important disease of the male breast
Gynecomastia
Breast cancer/tumor
The majority of lesions in male breasts are benign
Other disease arise from the skin&subcutan.
Fat necrosis
Lipoma
Epidermal inclusion cyst
9. Imaging of the Male Breast
Mammography - to diagnose gynecomastia and breast
carcinoma
Diagnostic mammography
biopsy
Standard mammographic views -
Magnification and spot compression views
suspicious findings on mammography
effective for evaluating male patient as it is for
female
10. Male Breast Tumor
Male breast tumor - uncommon
less than 1% of all malignancies
in men
only 1% of all breast cancers
The mean age of diagnosis is 67
years
Less than 6% of cases occur in males
under the age of 40 years.
11. Male Breast Tumor..
Clinical manifestation (S/S)
hard , fixed , painless mass
Bloody nipple discharge common
Secondary signs occur earlier in male patients
because of smaller breast size.
nipple retraction,
skin ulceration,
thickening,
increased breast trabeculation
Palpable axillary lymph nodes are present in about
50% of cases
12. Male Breast tumor
Histologic subtype :
Invasive ductul carcinoma- most common
85%
Male breast contains only ducts
Invasive lobular rare
No lobules formation in male breast
13. Male Breast Tumor :
Treatment
Same as for women
Surgery
Axillary node dissection
Chemotherapy
Radiation therapy
18. Defination Of
Gynecomastia
Gynecomastia is enlargement of
the gland tissue of the male breast
. During infancy , puberty
,and in middle aged to older men
gynecomastia can be common
19. Gynecomastia
Gynecomastia is the most common benign condition of the male
breast
It is enlargement of the male breast due to benign
ductal and stromal proliferation.
Causes breast enlargement
/subareolar mass with/without
associated breast pain
It can be unilateral, bilateral symmetric, or bilateral
asymmetric.
20. Gynecomastia
The hallmark of gynecomastia is its central
symmetric location under the nipple
Reversible in early stages if the cause is
corrected
Reversible phase progress to late periductal
edema with irreversible stromal fibrosis
21. Causes of Gynecomastia
Physiologic:

23. TYPES Of Gynecomastia
mammographic patterns -representing various degrees and
stages of ductal and stromal proliferation
Nodular gynecomastia
Dendritic gynecomastia
Diffuse glandular gynecomastia
24. Gynecomastia
Nodular G.- most common 77%
Pathology florid g. early phase
patients with gynecomastia < 1year
The majority of patients will present with
nipple tenderness , palpable lump
Mammography-nodular subareolar density
The typical mammographic confirms the diagnosis and
requires no further imaging work-up.
26. Nodular Gynecomastia
a subareolar fan- or disk-shaped hypoechoic nodule
surrounded by normal fatty tissue
The zone of transition may be poorly defined, with
lobular margin
Hypervascularity can be seen secondary to stromal
proliferation
In cases of equivocal clinical and mammographic
findings
follow-up evaluation
27. Chronic Dendritic Gynecomastia
Chronic dendritic gynecomastia (quiescent
phase) -20%
Patients with gynecomastia > 1 year.
Pathology fibrous g.- long standing gynecomastia
Fibrosis becomes the dominant process and is irreversible.
Mammography - dendritic subareolar
density with posterior linear projections
radiating into the surrounding tissue
toward the uoq
28. Chronic Dendritic
Gynecomastia
a subareolar hypoechoicstar-shaped,
fingerlike projections or spider legs
benignity - directly from the undersurface
of the nipple without causing any overlying
skin thickening or nipple retraction.
29. Chronic Dendritic Gynecomastia
U.S image subareolar hypoechoic nodule with star-shaped
projections into the surrounding echogenic fibrous tissue
30. Chronic Dendritic
Gynecomastia
The clinical history, particularly the duration of
symptoms, can also be helpful in making this
diagnosis.
patients may have an acute episode of gynecomastia in
addition to chronic dendritic gynecomastia.Both phases
can be seen at imaging simultaneously.
31. Diffuse Glandular Gynecomastia
Diffuse glandular 3%
Patients receiving exogenous estrogen
Mammography- enlargement of the breast , similar to
heterogeneously dense female breast.
Irreversible stromal fibrosis and ductal epithelial atrophy develop, the
breast enlargement may decrease but not completely resolve.
both nodular and dendritic features are seen surrounded by
diffuse hyperechoic fibrous breast tissue.
33. Pseudogynecomastia
Pseudogynecomastia a fatty proliferation of the
breasts , without proliferation of glandular tissue.
Difficult to distinguish from normal male breast on
mammography
Diagnosis requires clinical correlation with breast
enlargement
34. Less Common Benign
Conditions
Lipoma - second most common benign lesion in the
male breast
Mammography typically shows a subtle
encapsulated fatty mass in the palpated area
demonstrates one or multiple parallel, homogeneous,
and mildly hyperechoic masses under the skin
capsule is sometimes seen
36. Epidermal Inclusion Cyst
Epidermal inclusion cyst is the third most common benign
lesion in the male breast
Arise from obstructed or occluded hair follicles, at the sites of
previous skin trauma such as a surgical wound or insect bites
Composed of laminated keratin surrounded by stratified
squamous epithelium
37. Epidermal Inclusion Cyst
Hypoechoic lesion, which is contiguous to
the epidermis (arrows) (the claw sign) with
increased through transmission
well defined, dense, oval
mass contiguous to the skin in
the palpated region.
38. Benign Conditions
Associated with Gynecomastia
Pseudoangiomatous stromal hyperplasia (PASH)-
benign stromal tumor formed by myofibroblasts
and with glandular hyperplasia
Often incidentally seen in gynecomastia
Mammography- non calcified breast mass,
circumscribed or partially circumscribed
solid circumscribed hyper echoic masses
Recurrence is common after resection
40. Intraductal Papilloma
Intraductal papilloma - benign proliferation of
intraductal mammary epithelium.
Mammography - discrete dense mass against a
background of subareolar changes consistent
with gynecomastia
multiple encentric, subareolar, elongated
and welldefined hypoechoic masses, which
have irregular shapes and are possibly
confined to the lumina of markedly enlarged
central ducts
41. Intraductal papilloma
multiple eccentric, subareolar, elongated,well-defined,
hypoechoic masses ;US image shows cystic areas, which may
represent associated ductal ectasia.
discrete dense mass against a background of
subareolar density, which consistent with
gynecomastia
42. DIAGNOSTIC
EVALUATION

PATIENTS BREAST,
COMPLETE BLOOD COUNT(CBC)
MAMOGRAPHY,
ULTRASOUND,
FNAC
[FINE NEEDLE ASPIRATION
CYTOLOGY],
LIVER FUNCTION TEST AND
HORMONAL ASSESSMENT.
43. Conclusions
The majority (99%) of male breast lesions are benign
Mammography- for clinically suspicious lesions
accurate for diagnosing gynecomastia
useful for further characterization
The relationship of the mass to the nipple should be carefully
assessed
Encentric location is highly suspicious for cancer
the axillary region is helpful for staging In men
- cystic lesions commonly malignant
Cysts and complex masses should be worked up as potentially
malignant lesions
Suspicious lesion - biopsy - guidance is usually preferred
44. RISK FACTORS & COMPLICATIONS..
advanced age
prior irradiction of the chest
exogenous estrogen for prostate
cancer treatment
gender-reassignment procedures
liver disease and other diseases
associated with hyperestrogenism,
