A presentation is a pictorial representation of knowledge.

1. MAMMARY GLAND AND ITS’
BIRTH ANOMALIES
BY VISITH DANTANARAYANA
OF GROUP 201

2. STRUCTURE OF THE MAMMARY
GLAND

3. BREAST QUADRANTS

4. ARTERIAL SUPPLY
• INTERNAL THORACIC ARTERY
• LATERAL THORACIC ARTERY
• POSTERIOR INTERCOSTAL ARTERIES

5. VENOUS DRAINAGE
• AXILLARY VEIN
• INTERNAL THORACIC VEIN

6. LYMPHATIC DRAINAGE

7. IMPORTANCE OF THE LYMPHATIC
DRAINAGE
STAGE 4 BREAST CACER USES THE LYMPHATIC NODES OF
THE MAMMARY GLANDS TO SPREAD OR TO
INITIATE THE PROCESS OF METASTASIS.

8. A CARCINOMA ORIGINATING IN THE
MAMMARY GLAND (STAGE 4)
COULD SPREAD THROUGHOUT
A VAST AREA VIA THE LYMPH
NODES.

9. THIS GRAPH DEPICTS SOME STATISTICS
THAT WERE OBTAINED THROUGHOUT
THE YEAR OF 2013.

10. CLASSIFICATION OF BIRTH ANOMALIES
• POLYMASTIA AND POLYTHELIA
• GYNECOMASTIA
• AMASTIA AND ATHELIA
• CONGENITAL BREAST HTPOPLASIA OR
APLASIA

11. POLYMASTIA
THE PRESENCE OF SUPERNUMERARY BREASTS.
OCCURRENCE AVERAGES
FROM 0.22% - 6%

12. POLYTHELIA
THE PRESENCE OF
SUPERNUMERARY NIPPLES.

13. THE OCCURRENCE OF
SUPERNUMERARY BREASTS OR
NIPPLES TAKE PLACE ALONG A
MILK LINE WHICH STRETCHES
FROM THE AXILLA TO THE
INGUINAL REGION.

14. CONGENITAL BREAST HYPOPLASIA OR
APLASIA
• IDIOPATHIC ASYMMETRY
• TUBULAR/ TUBEROUS BREAST
• POLAND’S SYNDROME
• AMASTIA

15. POLAND’S SYNDROME
NAMED AFTER DR. ALFRED
POLAND.

16. OCCURS MORE IN MEN THAN IN
WOMEN; 3:1
SYNDROME IS SPORADIC, THEREFORE
OCCURS 1 OF EVERY 20,000 – 30,000
BIRTHS.

17. THE MAMMOGRAM SHOWS THE
DIFFERENCE BETWEEN THE LEFT
CHEST WHERE THE PECTORALIS
MUSCLE IS ABSENT AND THE NORMAL
RIGHT CHEST

18. BEFORE TREATMENT AND AFTER
TREATMENT

19. TUBULAR/ TUBEROUS BREAST
HERNIATION OF BREAST TISSUE
INTO THE AREOLA.
ALSO KNOWN AS THE SNOOPY – NOSED
SYNDROME.

21. BEFORE TREATMENT AND AFTER
TREATMENT

22. IDIOPATHIC AYMMETRY

23. AMASTIA
THE TOTAL ABSENCE OF A BREAST.
COULD BE UNILATERAL OR BILATERAL.
OFTEN ASSOCIATED WITH OTHER DOMINANT
AUTOSOMAL SYNDROMES SUCH AS
ECTODERMAL DYSPLASIA.

24. BILATERAL AMASTIA

25. UNILATERAL AMASTIA

26. GYNECOMASTIA
The most COMMON FORM OF BREAST
HYPERPLASIA.
