The authors report a variation of Poland's syndrome with ectopic right breast. Three surgeries were performed at different times: transposition flap to place the mammary gland in an anatomic position; reduction of the contralateral left breast; and implantation of a pre-molded silicone prosthesis to correct the malformation caused by the absence of the major and minor pectoral muscles. The surgeries were performed at six-month intervals, and the final outcome was new and acceptable positioning of the breasts.

Os autores apresentam uma variante da síndrome de Poland com mama direita ectópica. Foram realizados três tempos cirúrgicos: retalho de transposição para colocação da glândula mamária em posição anatômica; redução da mama contralateral esquerda; e implantação de prótese de silicone pré-moldada para correção do defeito causado pela agenesia dos músculos peitoral maior e peitoral menor. Com intervalo de seis meses entre as cirurgias, o resultado final apresenta novo posicionamento aceitável das mamas.

Anatomically normal female breasts are cone-shaped and located in the midclavicular line of the chest. Each breast has a papillary-areolar complex with a diameter between 3 cm and 5 cm and ranging in color and size according to the characteristics and physiological state of each person.
The anomaly in the case presented herein refers to a variation of Poland's syndrome described by Alfred Poland in 1841. This variation is rarely associated with absence of the serratus muscle or brachysyndactyly. The most common feature is the absence of the pectoralis major muscle and the occasional absence of the pectoralis minor muscle with reduction of the mammary gland size on the side of agenesis. To correct the reported case, two transposition flaps in a "Z" form were used for replacement of the mammary gland in the anatomical position. The incidence of this syndrome in the population is 1:30,000 and is more common among women1-6. These malformations may result from rupture of the subclavian arterial supply during pregnancy.
Several variations of Poland's syndrome have been described:
bilateral absence of the mammary gland and unilateral agenesis of the pectoralis major muscle; unilateral absence of the mammary gland with a rudimentary papillary-areolar complex and non-existent pectoralis major and minor muscles on the agenesis side; absence of the pectoralis major muscle and rudimentary breast with contralateral breast hypertrophy; unilateral absence of pectoralis major and minor muscles with rudimentary and ectopic breast with contralateral breast hypertrophy, as in the described case (Figures 1 to 3).

Other variants can be found in Poland's syndrome in relation to breast size and absence of one or both pectoral muscles.
Features of Poland's Syndrome
The features of this syndrome include hemithorax with an uneven and concave shape resulting from the absence of the pectoralis major muscle in one side of the chest and, less frequently, the pectoralis minor muscle, with hypomastia or mammary agenesis or other deformities that are usually congenital7.
The most frequent complaints are aesthetic, with loss of upper limb movements8.
A 22-year-old nulliparous Caucasian woman with an ectopic and reduced breast presented with absence of the pectoralis major and minor muscles on the right side. The intervention was achieved using two flaps: one above and other below. After detachment, the flaps were rotated by transposition and resembled a large Z-plasty or Holmstrom's flap at the bottom; this is a widely used in reconstruction technique (Figure 4).
Figure 4 - Preoperative aspect with design of flaps from the first surgical procedure.
To correct the imperfection caused by the absence of muscles, a pre-molded prosthesis was prepared using a plaster powder mixed with water that was later used to prepare a silicone prosthesis by a specialized company (Figure 5). This specialized prosthesis was used to correct the concavity resulting from agenesis of the muscle because the simple placement of a typical commercial prosthesis may not correct a deformity of the large axillary part.
Figure 5 - Postoperative appearance one month after the first surgical procedure following flap rotation.
After the right side was reconstructed, a mammaplasty was carried out on the contralateral side for correction of the volume asymmetry caused by the left breast. The transposition was the first-step surgical procedure (Figure 6). After six months, the second step of the surgical procedure involved reduction of the left breast, and finally, placement of the pre-molded silicone prosthesis was the third step.

The main surgical steps are illustrated in Figures 5 to 9. These three surgical steps were performed at intervals of six months. The images of pre- and postoperative periods demonstrate the anatomical differences and changes after the intervention (Figures 1 to 4 and 10 to 13).

Many surgical techniques could have been chosen to correct the deformities of the patient reported herein8-12. The transposition of two flaps with the pre-molded prosthesis insertion was the chosen procedure.
This procedure, which involved three surgical steps performed at six-month intervals, was discussed and approved by the patient during the preoperative period after receiving an explanation of the postoperative benefits.
Transposition flaps and rotations are widely used in reconstructions of both the mammary gland and the chest wall. In the case reported herein, after flap rotation, the marking resembled a "Z" of the classic Z-plasty and Holmstrom's marking at the bottom of the flap. The use of a silicone prosthesis pre-molded with plaster powder facilitated correction of the axillary concavity. This procedure can be used for other types of correction and reconstruction of congenital or acquired physical defects.
The final result was considered satisfactory by the patient and justifies the possible difficulties found for the definition of the technique to be chosen.
