MAMMARY GLAND AND ITS’ BIRTH ANOMALIES
BY VISITH DANTANARAYANA
OF GROUP 201
STRUCTURE OF THE MAMMARY GLAND
BREAST QUADRANTS
ARTERIAL SUPPLY
• INTERNAL THORACIC ARTERY• LATERAL THORACIC ARTERY• POSTERIOR INTERCOSTAL ARTERIES
VENOUS DRAINAGE
• AXILLARY VEIN• INTERNAL THORACIC VEIN
LYMPHATIC DRAINAGE
IMPORTANCE OF THE LYMPHATIC DRAINAGE
STAGE 4 BREAST CACER USES THE LYMPHATIC NODES OF THE MAMMARY GLANDS TO SPREAD OR TOINITIATE THE PROCESS OF METASTASIS.
A CARCINOMA ORIGINATING IN THE MAMMARY GLAND (STAGE 4)COULD SPREAD THROUGHOUTA VAST AREA VIA THE LYMPHNODES.
THIS GRAPH DEPICTS SOME STATISTICS THAT WERE OBTAINED THROUGHOUT
THE YEAR OF 2013.
CLASSIFICATION OF BIRTH ANOMALIES
• POLYMASTIA AND POLYTHELIA
• GYNECOMASTIA
• AMASTIA AND ATHELIA
• CONGENITAL BREAST HTPOPLASIA OR APLASIA
POLYMASTIA
THE PRESENCE OF SUPERNUMERARY BREASTS.
OCCURRENCE AVERAGES
FROM 0.22% - 6%
POLYTHELIA
THE PRESENCE OF
SUPERNUMERARY NIPPLES.
THE OCCURRENCE OF SUPERNUMERARY BREASTS OR NIPPLES TAKE PLACE ALONG A MILK LINE WHICH STRETCHES
FROM THE AXILLA TO THE INGUINAL REGION.
CONGENITAL BREAST HYPOPLASIA OR APLASIA
• IDIOPATHIC ASYMMETRY
• TUBULAR/ TUBEROUS BREAST
• POLAND’S SYNDROME
• AMASTIA
POLAND’S SYNDROME
NAMED AFTER DR. ALFRED
POLAND.
OCCURS MORE IN MEN THAN IN WOMEN; 3:1SYNDROME IS SPORADIC, THEREFORE OCCURS 1 OF EVERY 20,000 – 30,000 BIRTHS.
THE MAMMOGRAM SHOWS THE DIFFERENCE BETWEEN THE LEFT CHEST WHERE THE PECTORALIS
MUSCLE IS ABSENT AND THE NORMAL RIGHT CHEST
BEFORE TREATMENT AND AFTER TREATMENT
TUBULAR/ TUBEROUS BREAST
HERNIATION OF BREAST TISSUE INTO THE AREOLA.
ALSO KNOWN AS THE SNOOPY – NOSED SYNDROME.
BEFORE TREATMENT AND AFTER TREATMENT
IDIOPATHIC AYMMETRY
AMASTIA
THE TOTAL ABSENCE OF A BREAST.
COULD BE UNILATERAL OR BILATERAL.
OFTEN ASSOCIATED WITH OTHER DOMINANT AUTOSOMAL SYNDROMES SUCH AS
ECTODERMAL DYSPLASIA.
BILATERAL AMASTIA
UNILATERAL AMASTIA
GYNECOMASTIA
The most COMMON FORM OF BREAST HYPERPLASIA.
