Painful nodules and cords in Dupuytren disease.

PURPOSE: The etiology of Dupuytren disease is unclear. Pain is seldom described in the literature. Patients are more often disturbed by impaired extension of the fingers. We recently treated a series of patients who had had painful nodules for more than 1 year, and we therefore decided to investigate them for a possible anatomical correlate. METHODS: Biopsies were taken during surgery from patients with Dupuytren disease and stained to enable detection of neuronal tissue. RESULTS: We treated 17 fingers in 10 patients. Intraoperatively, 10 showed tiny nerve branches passing into or crossing the fibrous bands or nodules. Of 13 biopsies, 6 showed nerve fibers embedded in fibrous tissue, 3 showed perineural or intraneural fibrosis or both, and 3 showed true neuromas. Enlarged Pacinian corpuscles were isolated from 1 sample. All patients were pain free after surgery. CONCLUSIONS: Although Dupuytren disease is generally considered painless, we treated a series of early stage patients with painful disease. Intraoperative inspection and histological examination of tissue samples showed that nerve tissue was involved in all cases. The pain might have been due to local nerve compression by the fibromatosis or the Dupuytren disease itself. We, therefore, suggest that the indication for surgery in Dupuytren disease be extended to painful nodules for more than 1 year, even in the early stages of the disease in the absence of functional deficits, with assessment of tissue samples for histological changes in nerves.

In utero surgery rescues neurological function at birth in sheep with spina bifida.

We hypothesize that the neurologic deficit associated with open spina bifida is not directly caused by the primary defect but rather is due to chronic mechanical and chemical trauma since the unprotected neural tissue is exposed to the intrauterine environment. We report here that exposure of the normal spinal cord to the amniotic cavity in midgestational sheep fetuses leads to a human-like open spina bifida with paraplegia at birth, indicating that the exposed neural tissue is progressively destroyed during pregnancy. When open spina bifida was repaired in utero at an intermediate stage, the animals had near-normal neurologic function. The spinal cord was deformed but largely preserved. These findings suggest that secondary neural tissue destruction during pregnancy is primarily responsible for the functional loss and that timely in utero repair of open spina bifida might rescue neurologic function.

Anterior spreader flap technique: A new minimally invasive method for stabilising and widening the nasal valve.

BACKGROUND: The 'anterior spreader flap' is a new minimally invasive technique, for the treatment of nasal valve insufficiency or stenosis. The aim of this study was to present our experience with a series of patients with nasal valve dysfunction corrected by the minimally invasive spreader flap technique. METHODOLOGY: We performed a retrospective review of our patients with nasal valve malfunction who underwent the anterior spreader flap between June 2010 and June 2013. The patients had to judge their symptoms of nasal obstruction pre- and 12 months post-operatively by the Nasal Obstruction and Septoplasty Effectiveness (NOSE) quality-of-life assessment scale. The difference between the pre- and post-operative evaluations of each group and between the groups was calculated, and it was statistically analysed. RESULTS: Forty-three patients were treated. In seven patients, the anterior spreader flap was performed as a single procedure (group F), in 15 patients the anterior spreader flap was combined with a septoplasty and a turbinoplasty (group FST), in 10 patients with a turbinoplasty (group FT) and in 11 with a septoplasty (group FS). All patients reported significant post-operative improvement in nasal breathing (p < 0.05). The mean improvement (diffNOSE) of all patients was 54.2 points. The 'FS' group and the 'FST' group showed best post-operative results, but there were no significant differences between the groups (p > 0.8). CONCLUSIONS: The anterior spreader flap is an effective and safe method for minimally invasive improvement of nasal breathing in patients with nasal valve dysfunction.

Gene expression along the cerebral-spinal axis after regional gene delivery.

We demonstrate here that intracerebroventricular or spinal cord (intrathecal) injection of either plasmid DNA alone or cationic liposome: DNA complexes (CLDCs) produces significant levels of expression of both reporter genes and biologically relevant genes in nonparenchymal cells lining both the brain and the spinal cord. Gene expression was identified both within the spinal cord and the brain after intracerebroventricular or intrathecal injection of either CLDCs or plasmid DNA alone. Intracerebroventricular or intrathecal injection of CLDCs containing the beta-galactosidase (beta-Gal) gene produced patchy, widely scattered areas of beta-Gal expression. The chloramphenicol acetyltransferase (CAT) reporter gene product reached peak levels between 24 hr and 1 week postinjection, and was still present at significant levels 3 weeks after a single intracerebroventricular or intrathecal injection. Intrathecal injection of the human granulocyte colony-stimulating factor (G-CSF) gene produced high levels of hG-CSF activity in both the spinal cord and the brain. Intracerebroventricular injection of CLDCs containing the murine nerve growth factor (NGF) gene increased mNGF levels in the hippocampus, a target region for cholinergic neurons in the medial septum, and increased cholinergic neurotransmitter synthetic enzyme choline acetyltransferase (ChAT) activity within the brain, a well-characterized effect of both purified and recombinant NGF protein. These findings indicate that intracerebroventricular or intrathecal injection of CLDCs can produce significant levels of expression of biologically and therapeutically relevant genes within the CNS. Efficient gene transfer into the CNS will facilitate the evaluation of gene function and regulation within the brain and spinal cord. We attempted to transfer and express genes within the brain and spinal cord by direct CNS injection of either DNA alone or CLDCs into the intraventricular and subarachnoid compartments. We show that intracerebroventricular or spinal cord (intrathecal) injection of either plasmid DNA alone or CLDCs produces significant levels of expression of both reporter genes and biologically relevant genes in nonparenchymal cells lining both the brain and the spinal cord. Intrathecal injection of the hG-CSF gene produced high levels of hG-CSF activity in both the spinal cord and the brain. Intracerebroventricular injection of CLDCs containing the murine NGF gene increased mNGF levels in the hippocampus, and increased cholinergic neurotransmitter synthetic enzyme ChAT activity within the brain. Locoregional diffusion of gene products expressed by transfected meningeal lining cells into brain and spinal cord parenchyma could potentially target secreted proteins within brain and spinal cord regions relevant to neuropathological states while limiting peripheral side effects.

Efficient gene expression in skin wound sites following local plasmid injection.

Transfection of the skin by local gene delivery, as well as widespread transfection of systemic tissues following intravenous injection of cationic liposome/DNA complexes have been reported. Here, we show that surgically wounded mouse skin can be transfected either by local injection of DNA alone or by intravenous injection of optimized cationic liposome/DNA complexes; however, direct cutaneous injection produces much higher levels of gene expression in the skin, which is targeted to dermal and subdermal layers. High levels of chloramphenicol acetyltransferase activity were present from 3 h to 2 wk following direct injection of a gene expression plasmid into wounded skin and were maintained at detectable levels up to 8 wk after injection. Expression of transferred chloramphenicol acetyltransferase as well as beta-GAL genes was localized to fibroblasts, macrophages, and adipocytes as determined by histochemistry and immunohistochemistry. Further- more, local injection of a human granulocyte- colony-stimulating factor gene expression plasmid produced high levels of the biologically relevant human granulocyte-colony-stimulating factor protein in wounded mouse skin. This efficient and simple method of site-specific gene transfer into wounds may lead to the development of cutaneous gene therapy directed against disorders of abnormal cutaneous wound healing.

Efficacy of cultured epithelial autografts in pediatric burns and reconstructive surgery.

BACKGROUND: Cultured epithelial autografts are regularly used in burn patients, but they have not been tested in patients undergoing reconstructive surgery. The aim of this study was to analyze and compare the efficacy of cultured grafts in both burn and reconstructive surgery patients. METHODS: In six children with severe and massive burns, full-thickness areas were grafted with cultured grafts. In another six children with hypertrophic or hyperpigmented scars, or both, cultured grafts were used to cover defects resulting from scar excision or deep dermabrasion. RESULTS: In burn surgery the final cover rate averaged 60% (range, 0% to 100%). The functional and cosmetic results were good and at least equivalent to results after conventional grafting. Fragility, infection, and, in particular, mechanical instability of cultured grafts during the first weeks after transplantation were the main problems encountered. In reconstructive surgery the final cover rate was 100% in all patients. The functional and cosmetic results were very good and considered better than those obtained by using conventional grafting techniques. No major management problems were encountered. CONCLUSIONS: In massively burned children, cultured epithelial autografts represent an effective additional and potentially lifesaving method to conventional grafting. Questions remain regarding the use of this technique to treat less severe burns. For resurfacing-type scar revisions, cultured epithelial autografts yield excellent results that appear to be superior to those of conventional techniques.

The fetal spinal cord does not regenerate after in utero transection in a large mammalian model.

OBJECTIVE: Regeneration and functional recovery after spinal cord transection do not occur in mammalian animals and humans postnatally. The goal of this study was to test whether in utero transection of the fetal spinal cord is succeeded by anatomic healing and functional recovery. METHODS: In five sheep fetuses, at 60 days of gestation and 75 days of gestation (term = 150 d), the spinal cord was completely transected at T10. The animals were delivered near term by cesarean section for clinical evaluation, measurement of cortical somatosensory evoked potentials, and morphological assessment. RESULTS: The newborn lambs demonstrated sensory-motor paraplegia, were incontinent of urine and stool, and exhibited a spinally generated, ambulatory pattern of the hindlimbs. No cortical somatosensory evoked potentials could be recorded in response to posterior tibial nerve stimulation, although potentials from the ulnar nerve, which enters the cord rostral to the lesion, were normal in all animals. Histologically, no neuronal connections across the transection site were identified. The cord proximal to the lesion was grossly normal, whereas distal to the transection, it appeared slightly smaller but with the cytoarchitecture preserved. CONCLUSIONS: Unlike in lower vertebrate and avian species, the fetal ovine spinal cord has no detectable spontaneous regenerative capabilities when transected during midgestation. Gap formation after transection, secondary posttraumatic cell death, and missing guiding channels for sprouting axons may be factors involved in the absence of any regenerative response.

Artificial skin, split-thickness autograft and cultured autologous keratinocytes combined to treat a severe burn injury of 93% of TBSA.

Despite refinements in burn shock resuscitation, improvements in surgical techniques, advances in intensive care medicine and the presence of very expert surgeons, the treatement of patients with severe burns exceeding 60% TBSA remains a big challenge. A major problem in the treatment of severe burn injuries is the lack of autologous skin. In selected cases cultured epidermal autograft (CEA) may be used. However, they are available only 2-3 weeks after biopsy, thus requiring a temporary wound closure after necrosectomy. A new option is Integra(TM), an artificial skin consisting of a bilayer membrane system. The three-dimensional porous matrix from bovine tendon collagen and a glycosaminoglycan layer is covered by a silicon sheet. The latter prevents fluid loss from the wounds and serves as a barrier against germ invasion. After adequate vascularisation of the dermal template, the silicon layer is removed and replaced by a thin autograft. We present a 26-year old male who sustained a 93% TBSA burn injury (60% full-thickness burn, 33% partial-thickness burn). He was treated with artificial skin, split-thickness autograft and CEA in combination. The clinical history and the follow-up of approx. 1 year are presented and the results discussed. We consider the survival of this patient being a result of the therapeutic progress of the recent decades.

The qualification of different free muscle transplants to reconstruct mimic function: an experimental study in rabbits.

With the scutuloauricularis muscle, we developed a new model for experimental free transplantation of mimic muscles in the rabbit and studied the qualification of different muscles for free functional grafting into the position of the facial muscle, which is to be replaced. Forty adult female white New Zealand rabbits were distributed to four groups of 10 rabbits each. In group 1, the operative techniques of the new transplantation models were developed in the scutuloauricularis muscle, the pectoralis descendens muscle, and a comparable part of the rectus femoris muscle. In group 2, the scutuloauricularis muscle was transplanted orthotopically with microneurovascular anastomoses on the left side; in group 3, the pectoralis descendens muscle was transplanted into the position of the scutuloauricularis after its removal; and with the animals in group 4, a piece of the rectus femoris muscle was transplanted into the position of the mimic muscle after its removal. In all muscle transplants, the neurovascular supply was reestablished microsurgically by end-to-end anastomoses to the superficial temporal vessels and direct nerve coaptation to the facial nerve branches supplying originally the scutuloauricularis muscle. Nine months after transplantation, force measurements were performed in all transplanted muscles and the scutuloauricularis muscles of the control side. Cross-sections stained for ATPase after alkaline preincubation at pH 10.4 were used for computer-assisted planimetry of the muscle fibers. The orthotopically transplanted scutuloauricularis muscles reached with 2.84 (+/-1.04) N for maximal tetanic tension on the average 87.7 (+/-32.1) percent of that of the control scutuloauricularis muscles, the pectoralis descendens muscles with 4.25 (+/-2.15) N on the average 188.7 (+/-100.7) percent of that of the controls, and the pieces of rectus femoris muscles 6.62 (+/-2.16) N or 185.3 (+/-45.4) percent of that of the controls. All three muscles were identified as fast contracting muscles before and after transplantation. By transplantation, the content of type II muscle fibers changed from 58.2 to 68.0 percent in the scutuloauricularis muscle, from 62.4 to 74.4 percent in the musculus pectoralis descendens, and from 92.5 to 82.8 percent in the rectus femoris muscle. For the first time, an experimental model for free transplantation of mimic muscles was developed and functionally assessed. The most important result of this study was the fact that the double-sized muscle grafts developed twice the force of the control scutuloauricularis muscles, although reinnervated by the original muscle nerve branch. This result underlines the usefulness of overdimensioning during clinical muscle transplantation. It was also shown that parts of big muscles can be grafted with results similar to those experienced with complete smaller muscles.

Midgestational sciatic nerve transection in fetal sheep results in absent nerve regeneration and neurogenic muscle atrophy.

In order to test whether fetal nerve healing and regeneration result in complete functional recovery, we transected the sciatic nerve at trunk level in 13 midgestational sheep fetuses. In 10 fetuses immediate microsurgical nerve coaptation was performed. The neonatal lambs were evaluated clinically, electrophysiologically, and histologically. On the transected side, the 10 surviving lambs showed a sensorimotor sciatic nerve paralysis and atrophy of the muscles innervated by the sciatic nerve. Somatosensory evoked potentials were weakly present in 5 animals and absent in 5 animals. Histologically, minimal signs of axonal regeneration, massive degeneration of the entire nerve, and a marked neurogenic muscle atrophy were found. These unexpected results differ from the findings after peripheral nerve transections in late gestational sheep fetuses and also from the classic wallerian degeneration-regeneration pattern that follows adult nerve injury. We speculate that the almost absent regenerative potential at midgestation is related to axotomy-induced neurotrophic factor deprivation during a developmental phase where the neurons are critically dependent on growth factor for survival.

Fetal reconstructive surgery: experimental use of the latissimus dorsi flap to correct myelomeningocele in utero.

A recent study in human fetuses with myelomeningocele produced evidence that nonclosure of the spine leads to progressive damage of the exposed spinal cord during pregnancy. Thus in utero coverage might spare function. We tested the use of the latissimus dorsi flap for fetal myelomeningocele repair. In seven sheep fetuses, a lumbar myelomeningocele type of lesion was created at 75 days' gestation and was covered with a "reversed" latissimus dorsi flap at 100 days. At term, the three survivors had healed cutaneous wounds and normal hindlimb function. The vascular pedicle of the latissimus dorsi flap was patent, the viable flap covered the entire lesion, and the underlying spinal cord was grossly intact. We conclude that the latissimus dorsi flap repair is suitable for fetal surgery and provides efficient coverage of the lesion. These results have clinical implications, since fetal myelomeningocele repair may be a compelling way to reduce the severe neurologic deficit in humans.

Functional and morphometric evaluation of end-to-side neurorrhaphy for muscle reinnervation.

This study was undertaken to quantify the effect of motor collateral sprouting in an end-to-side repair model allowing end organ contact. Besides documentation of the functional outcome of muscle reinnervation by end-to-side neurorrhaphy, this experimental work was performed to determine possible downgrading effects to the donor nerve at end organ level. In 24 female New Zealand White rabbits, the motor nerve branch to the rectus femoris muscle of the right hindlimb was dissected, cut, and sutured end-to-side to the motor branch to the vastus medialis muscle after creating an epineural window. The 24 rabbits were divided into two groups of 12 each, with the second group receiving additional crush injury of the vastus branch. After a period of 8 months, maximum tetanic tension in the reinnervated rectus femoris and the vastus medialis muscles was determined. The contralateral healthy side served as control. The reinnervated rectus femoris muscle showed an average maximum tetanic force of 24.9 N (control 26.2 N, p = 0.7827), and the donor- vastus medialis muscle 11.0 N (control 7.3 N, p = 0.0223). There were no statistically significant differences between the two experimental groups (p = 0.9914). The average number of regenerated myelinated nerve fibers in the rectus femoris motor branch was 1,185 +/- 342 (control, 806 +/- 166), and the mean diameter was 4.6 +/- 0.6 microm (control, 9.4 +/- 1.0 microm). In the motor branch to the vastus medialis muscle, the mean fiber number proximal to the coaptation site was 1227 (+/-441), and decreased distal to the coaptation site to 795 (+/-270). The average difference of axon counts in the donor nerve proximal to distal regarding the repair site was 483.7 +/- 264.2. In the contralateral motor branch to the vastus medialis muscle, 540 (+/- 175) myelinated nerve fibers were counted. In nearly all cross-section specimens of the motor branch to the vastus medialis muscle, altered nerve fibers could be identified in one fascicle distal and proximal to the repair site. The results show a relevant functional reinnervation by end-to-side neurorrhaphy without functional impairment of the donor muscle. It seems to be evident that most axons in the attached segment were derived from collateral sprouts. Nonetheless, the present study confirms that end-to-side neurorrhaphy is a reliable method of reconstruction for damaged nerves, which should be applied clinically in a more extended manner.

Latissimus dorsi flap procedures to cover myelomeningocele in utero: a feasibility study in human fetuses.

There is experimental and clinical evidence that in utero repair of myelomeningocele (MMC) may preserve neurological function. In five aborted human fetuses (gestational age, 18 to 29 weeks), the authors tested whether proximally and distally based latissimus dorsi flaps (LDF) can be used to cover MMC lesions. Fetal soft tissues were developed enough to allow surgical handling, preparation of both flap types was technically easy, and the vascular pedicles could be preserved. The proximally pedicled LDF was suitable to cover the upper spine from lower cervical to lower thoracic levels, whereas the distally pedicled LDF was suitable to cover the spine between lower thoracic and lower sacral levels. These results suggest that various LDF procedures are technically feasible in early gestational human fetuses and could be used for in utero repair of MMC.

The spinal cord lesion in human fetuses with myelomeningocele: implications for fetal surgery.

Recently produced experimental evidence suggests that secondary traumatic injury and degenerative changes, acquired in utero, to the openly exposed neural tissue may be primarily responsible for the massive neurological deficit associated with myelomeningocele (MMC). The goal of this study was to examine the morphology of human fetuses with MMC to determine if acquired trauma to the spinal cord could be identified. The MMC lesions with surrounding tissues from 10 human fetuses ranging in gestational age between 19 and 23 weeks were prepared with serial histological sections. The MMC lesions were characterized by an open vertebral arch, an open dura mater fused laterally to the dermis, and an open pia mater fused laterally to the epidermis. The spinal cord was exposed, without any meningeal, bony, or cutaneous covering, and was resting on the dorsal aspect of the abnormal arachnoid sac created by the fusion of the meninges to the cutaneous tissues. The exposed neural tissue had undergone varying degrees of recent traumatic injury as a result of its exposed position, ranging from nearly complete preservation of neural elements in four cases to nearly complete loss in two cases. The neural tissue remaining in the MMC with partial loss contained hemorrhages and abrasions from recent injury, suggesting that injury occurred during passage through the birth canal. The presence of dorsal and ventral parts of the cord with nerve roots and ganglia demonstrated that these structures had formed during development and that the loss of tissue by injury was a secondary change. The results support the concept that performing in utero surgery could protect the exposed but initially well-developed and uninjured cord, prevent secondary neural injury, and preserve neural function in the human fetus with myelomeningocele.

Creation of myelomeningocele in utero: a model of functional damage from spinal cord exposure in fetal sheep.

A recent study in human fetuses with myelomeningocele (MMC) suggested that the primary malformation is not neural but a failed closure of the posterior vertebral column and paraspinal soft tissue, which leads to exposure and secondary destruction of the spinal cord. The goal of this study was to test whether chronic exposure of the normal spinal cord to the amniotic space produces a lesion similar to human MMC. In fetal sheep at 75 days' gestation (group A) and 60 days' gestation (group B) (term = 150 days), the lumbar spinal cord was exposed to the amniotic cavity by excising skin and paraspinal soft tissues, and by performing a laminectomy. Some animals from both groups were fetectomized and assessed morphologically at 100 days' gestation. The remainder were delivered near term and assessed clinically, electrophysiologically, and morphologically. In group A, all animals showed MMC-type pathology. The exposed spinal cord was herniated out of the spinal canal and rested on the dorsal membranes of a cystic sac. The neural tissue was stretched and flattened out. Histologically, the hallmarks of the spinal cord were not discernable and the cytoarchitecture was lost. These changes were less severe at 100 days than at term. The three survivors in group A were paraplegic. In group B, the two survivors and two fetuses harvested at 100 days had healed skin wounds and near normal spinal cord histology. The other animal harvested at 100 days had a MMC-type lesion with less severe histological changes. The two survivors had a mild paraparesis.(ABSTRACT TRUNCATED AT 250 WORDS)

In utero repair of experimental myelomeningocele saves neurological function at birth.

In a previous series of fetal sheep experiments, the authors demonstrated that midgestational exposure of the normal spinal cord to the amniotic space leads to a myelomeningocele (MMC) at birth that closely resembles human MMC phenotypes in terms of morphology and functional deficit. The present study tested whether delayed in utero repair of such evolving experimental MMC lesions spares neurological function. In 12 sheep fetuses, a spina bifida-type lesion with exposure of the lumbar spinal cord was created at 75 days' gestation (full term, 150 days). Four weeks later, the developing MMC lesions were repaired in utero for seven fetuses (five fetuses died before this time). Of those that had repair, three were delivered near term by cesarean section, and four died in utero or were aborted. All survivors had healed skin wounds and near-normal neurological function. Despite mild paraparesis, they were able to stand, walk, and perform demanding motor tests. Sensory function of the hindlimbs was present clinically and confirmed electrophysiologically. No signs of incontinence were detected. Histologically, the exposed and then covered spinal cord showed significant deformation, but the anatomic hallmarks as well as the cytoarchitecture of the spinal cord essentially were preserved. These findings show that timely in utero repair of developing experimental MMC stops the otherwise ongoing process of spinal cord destruction and "rescues" neurological function by the time of birth. Because there is evidence that a similar secondary damage to the exposed neural tissue also occurs in human MMC, we propose that in utero repair of selected human fetuses might reduce the neurological disaster commonly encountered after birth.

Videoscopic plastic surgery.

Efforts to explore the cavities of the human body date back to Hippocrates, who pioneered "endoscopic" procedures by performing rectoscopy. The following 2400 years brought tremendous technical advances and an understanding of normal and abnormal human anatomy and physiology. In this century, organ transplantation, microsurgery, and most recently fetal surgery have stepped out of the realm of science fiction and into reality.

[Methods, indications and validation of intraoperative nerve conductivity testing]. / Methode, Indikationen und kritische Wertung der intraoperativen Nervenfunktionsdiagnostik*

During nerve surgery, electrodiagnostic methods are applied to assess the availability and viability of nerve fibers and to adjust operative measures accordingly. The validity of this procedure is verified by histology and by the outcome of the operation. This paper explains the techniques of intraoperative nerve action potential (NAP) and somatosensory evoked potential (SEP) recording, how to interpret the electrodiagnostic results, and describes both the special features and the limitations of the methods. We found reliable results of neurography, detecting the presence or absence of spontaneous nerve regeneration across a lesion in continuity months before the reinnervation reached its final target. Based on our results, we suggest that NAP recording of the exposed nerve can widely prevent unnecessary nerve or fascicle resection. Besides this important indication, the nerve function evaluation was successfully used in nerve surgery whenever the quality of the nerve parenchyma was crucial to the operative management. Further indications such as evaluating brachial plexus lesions and the condition of nerve roots, judging the proximal coaptation site in nerve reconstruction, tracing the site of a nerve lesion and identifying the pathophysiology of nerve malfunction are exemplified. Intraoperative nerve conductivity testing should not be considered as a replacement of but rather as a complement to preoperative clinical, electrophysiological and imaging evaluations and a thorough intraoperative morphological examination.

[Breast implant and desmoid tumor: is there an etiological relation?]. / Mammaimplantat und Desmoidtumoren: Besteht ein Zusammenhang?

Desmoid tumor of the breast is a rare lesion. So far only 8 cases in which the tumor origin was linked to a breast implant have been published. Whether there is an etiological relation to the silicone implant or if it is pure coincidence is not evident at this time. We present the case of a 24-year-old female with congenital asymmetric breasts who underwent breast augmentation in our division on the left side and 15 months later had a breast reduction on the other side. Nine years after the first operation we found a suspicious lesion on the side of the breast implant. The histological result of the excisional biopsy showed an aggressive fibromatosis "arising from" the capsule around the silicon implant. We discuss the possible association of breast implant and desmoid tumor of the breast and evaluate the diagnostic and therapeutic options for desmoid tumors of the breast.
