Poland's syndrome is described as the absence of the pectoralis major muscle associated with deformities of the hands such as variable syndactylia, absence of the middle phalanx, fusion of the carpal bones, or shortening of the forearm. There may be variations in the extent of the thoracic impairment from the absence of anterior portions of ribs or costal cartilages to "sunken chest," which is generally used to describe thoracic depressions associated with skeletal dysplasia. In general, the areolarpapillary complex is in an upper region in men, and women have hypoplastic breasts. A 32-year-old female patient with Poland's syndrome sought our outpatient service wishing to improve the appearance of her thorax and breasts. She had undergone surgical intervention 7 years earlier with implantation of a silicone breast prosthesis, aiming to minimize the characteristic thoracic deformity. After an assessment, we opted to replace the prosthesis. During the intraoperative period, an area of osteocartilaginous resorption about 4 cm in diameter was observed in a region of costochondral articulation. After the surgery, the patient progressed as expected. Extensive research was carried out on the deformity found, and the patient was referred to a thoracic surgeon. Anterior regional bone resorption in the left hemithorax can be an important surgical finding. It can also represent a decrease in cardiac protection, necessitating greater care in cases of breast prosthesis replacement and the requirement of specific imaging examinations such as CT scans in order to minimize surgical risks.

Congenital deformities or deformities impairing thoracic development rarely cause severe functional problems, unlike other severe anomalies affecting limbs. They are also aesthetically more tolerable and concealable than larger facial fissures1-4.
Poland5 was the first to describe an anomaly involving the absence of the pectoralis major muscle associated with hand deformities, which was later described by Froriep6. Recently, the studies of Ravitch7 resolved many issues regarding the diagnosis and treatment of such anomalies.
Poland's syndrome comprises a variety of anomalies specifically affecting the trunk and upper limbs. It is more common in men than in women and is rarely bilateral. The absence of the sternal portion of the pectoralis major muscle is considered to be the mildest manifestation of this syndrome. Impairment of other adjacent muscles (i.e., the pectoralis minor, serratus anterior, latissimus dorsi, and external oblique) has been reported in the literature4.
Skeletal deformities may include "sunken chest," which is generally used to describe thoracic depressions associated with skeletal dysplasia, as well as the absence of anterior portions of the ribs or costal cartilage8. In severe cases, there may be significant paradoxical movement of the thorax and anterior herniation of the lungs. The scapulae may be smaller and winged (Sprengel's deformity). The skin in this region is hypoplastic, and the subcutaneous mesh is flatter. In general, the areolarpapillary complex is in an upper region in men, while women have hypoplastic breasts. Hand deformities may include variable syndactylia, absence of phalanges, carpal bone fusion, or forearm shortening4.
Studies demonstrate a low incidence of Poland's syndrome (1:30,000) in Brazil; it is believed that this syndrome is genetically influenced and is related to chromosomal anomalies4.
A 32-year-old Caucasian female patient visited Prof. Dr. Ewaldo Bolívar de Souza Pinto, Outpatient Service of Plastic Surgery, with history of Poland's syndrome on the left side, absence of the pectoralis major muscle, and depression in the left anterior thoracic wall resulting in "sunken chest" (Figure 1). After clinical examination, the subcutaneous mesh in the affected region and the areolarpapillary complex were found to be hypoplastic, while the left side was in an upper position relative to the right. The left upper limb exhibited normal development, and the patient did not have any systemic diseases.
The patient underwent a surgical procedure for implantation of a left breast prosthesis 7 years earlier in an attempt to correct or minimize the thoracic deformity. She sought our service to replace the breast prosthesis as she was unhappy with its shape (Figure 2).
Routine preoperative examinations were performed. After analyzing the chest X-ray in the posterioranterior view, the existence of an upper bone depression at the left side was observed, with the mediastinum deviating to the right (Figure 3). A circular radiopaque image was observed in the middle third of the left hemithorax, which is compatible with the breast prosthesis. After the preanesthetic visit, the patient underwent breast prosthesis replacement under general anesthesia of basal flow.
The incision was made over the scar in the submammary crease to the left side to access the prosthetic cavity. After the prosthesis was removed, osteocartilaginous resorption (about 4 cm in diameter) was observed in the region of costochondral articulation (Figure 4).
Partial capsulectomy was performed, and a new round high-profile mammary prosthesis with a polyurethane surface was placed (235 mL) (Figure 5) with vacuum drainage of the prosthesis cavity for 72 hours.
The patient was discharged on the first postoperative day and exhibited good progress. On the 30th postoperative day, she was sent to the thoracic surgeon who requested a CT scan for assessment and follow-up (Figure 6).
Surgical correction of congenital deformities or deformities impairing thoracic development can be important in the prevention of progressive scoliosis, cardiopulmonary restriction, and adverse psychological development.
The literature does not contain cases of total or regional secondary resorption in the presence of breast prostheses. However, it is known that the compression results in bone absorption and subsequent bone remodeling.
During prosthesis removal, 3 circular silicone devices used for prosthetic fastening in the thoracic wall were observed within the cavity (Figure 3). This observation led the authors to believe that anterior regional bone resorption did not occur after the first surgery since such devices are normally positioned over the rigid surface.
Anterior regional bone resorption in the left hemithorax was an important surgical finding; considering the possibility of decreased cardiac protection, we decided to replace the prosthesis with another prosthesis that was greater in volume to occlude the observed defect. The patient was sent to the thoracic surgeon for follow-up and planning of corrective surgery.
Although the literature does not contain information regarding bone resorption as result of breast prosthesis implantation in Poland's syndrome, we believe that greater attention is necessary in cases involving breast prosthesis replacement and specific imaging examinations such as CT scans should be performed.
