An unusual case of desmoplastic melanoma containing an osteoclast-like giant cell-rich nodule.

The authors describe a case of a 5 cm mixed desmoplastic melanoma occurring on the cheek of an 88-year-old white woman. The epidermis showed the features of lentigo maligna. Within the dermis, there was a mixed desmoplastic melanoma with 2 components. The first component consisted of infiltrative malignant spindled cells with prominent stromal fibrosis and had the typical appearance of desmoplastic melanoma. The second component was within the deep half of the tumor and consisted of a densely cellular nodule composed of spindled melanocytes admixed with many osteoclast-like giant cells. There was a peripheral neurotropism and tumor invaded bone. The Breslow thickness was 14 mm. On followup, a sacral metastasis was discovered, which had a similar morphology to the deep cellular nodule. Immunohistochemistry of spindled cells both inside and outside the nodule showed S100 positivity with the absence of other melanocytic markers (HMB-45, Melan-A). Smooth muscle actin and p63 were focally positive. The osteoclast-like giant cells expressed CD68 and MiTF. Array comparative genomic hybridization of the typical desmoplastic melanoma region had a flat profile, whereas the cellular osteoclast-like giant cell­rich region displayed important cytogenetic anomalies, some of which have been previously described in melanomas. The main array comparative genomic hybridization findings were confirmed by fluorescence in situ hybridization using specific probes. The differences in morphology and molecular cytogenetics between the 2 areas suggest that these might represent the progression or emergence of a more aggressive clone within the tumor. Subsequent metastatic spread to the bone may be a result of accumulated cytogenetic abnormalities.

Pyoderma gangrenosum: an exceptional complication of venous access device.

INTRODUCTION: Pyoderma gangrenosum (PG) is a rare disease whose precise etiology remains unknown. It causes rapidly developing skin necrosis and can occur after surgery, or after a nonspecific external stimulus. This condition is difficult to diagnose because it often mimics a fulminant infection. CLINICAL CASE: We present a case of very significant local presentation of PG after placement of a venous access device. Fifteen days after placement, the patient developed extensive cutaneous ulcers and necrosis in the subclavicular area, which led to the misdiagnosis of infection. The device was removed and the patient was given antibiotics. Because there was no improvement following antibiotic treatment, combined with the worrying and extensive appearance of the skin and extremely intense pain, the diagnosis of PG was made. The patient was immediately treated with high-dose corticosteroids, resulting in rapid improvement of the lesions and relief of pain. CONCLUSION: PG should be considered in cases of extensive, antibiotic-resistant ulceration and treatment with corticosteroids should be initiated. Clinical improvement is usually dramatic, with almost immediate suppression of the pain and arrest of the lesion's progression. Early treatment is the best guarantee for an effective recovery.

Percutaneous fasciotomies and fat grafting: indications for breast surgery.

BACKGROUND: The management of breast deformities can be very difficult in the presence of breast shape retraction. Percutaneous fasciotomies, which release fibrous strings, can be a very useful tool for shape improvement in the recipient site for a fat graft. OBJECTIVES: The authors evaluate the efficacy of fasciotomies in association with fat grafting in breast surgery. METHODS: A retrospective chart review was conducted for 1000 patients treated with concurrent fasciotomies and fat grafting between January 2006 and December 2011. The recipient site was prepared with fasciotomies, and fat was harvested from other parts of the body using a low-pressure 10-mL syringe lipoaspiration system. Fat was centrifuged and injected into the breast for reconstruction or chest deformities. The postoperative appearance of the breast scars was scored by both the surgeon and the patient. Each complication was recorded, including instances of hematoma, infection, tissue wounds, scar healing, and fat necrosis. RESULTS: In this series of patients, for whom the primary indications for the procedure were sequelae of breast-conserving surgery after cancer, latissimus dorsi flap breast reconstruction, breast implant reconstruction, tuberous breast, Poland syndrome, and funnel chest, we recorded the following complications: 0.8% local infections (8/1000), 0.1% delayed wound healing that required medical care (1/1000), and 3% fat necrosis (31/1000). Fasciotomy scarring was considered minor by the patient in 98.5% of cases and by the surgeon in 99% of cases at 1 year postoperatively. CONCLUSIONS: Fat grafting is a safe and reliable technique that improves the aesthetic outcomes of breast surgery. Percutaneous fasciotomies provide excellent aesthetic results and an improvement in breast shape with no scarring. In our experience, both fat grafting and fasciotomies offer a durable result over the long term.

Breast asymmetry and pectus excavatum improvement with fat grafting.

BACKGROUND: In women, pectus excavatum malformation can cause modified breast morphology, resulting in mammary asymmetry, which can be increased by placing mammary implants alone. Fat transfer can be an elegant solution to increase the volume and projection of the breast. OBJECTIVES: The authors discuss their experience treating pectus excavatum with fat transfer (lipomodeling) since 2000. METHODS: The charts of 19 consecutive patients with a pectus excavatum breast asymmetry who underwent lipomodeling treatment at the authors' facility between January 2000 and November 2011 were retrospectively reviewed. Patients were separated using the Chin classification (type 1, 2, and 3). Data points for each patient included age and body mass index, number of interventions and volume of fat injected during each session, total volume transferred, and postoperative complications. The clinical result was evaluated by the patient and the surgical team on a 4-point scale: very good, good, fair, or poor. RESULTS: Most (74%) patients in this series had type 3 Chin pectus excavatum. The average age was 28 years, and the average body mass index was 20.3. The average number of lipomodeling sessions was 1.63, and the average volume of fat transferred was 230 mL per session and 375 mL total. The patients and the surgical team were very satisfied or satisfied in 95% of cases and considered the result fair in 5% of cases. There were no complications. CONCLUSIONS: Fat transfer for treatment of pectus excavatum yields very good (natural and stable) results and high patient satisfaction rates, which makes this technique our preferred method for treating thoracomammary malformations in pectus excavatum.

Breast amputation correction of a horse bite using the lipomodeling technique.

UNLABELLED: Mammary gland development is an important phase of puberty, and it marks the passage into adulthood for women, so any trauma leading to mammary deformities has an important physical and psychological impact. Often, classic techniques are difficult to use in the treatment of traumatic breast lesions. In this article, the authors present an exceptional case of breast reshaping by lipomodeling in a teenage patient who had experienced a horse bite. Treatment included 2 fat grafting sessions with fasciotomies, nipple reconstruction using a bifoliated flap, and areolar tattooing, all without any complications. We achieved a satisfactory result with a symmetric volume, a natural tissue consistency, and sensation improvement, all of which were maintained as the patient grew. In our experience, fat transfer was a safe and reliable technique that provided a good and stable aesthetic result, improving the volume and shape without additional scarring or implant devices. LEVEL OF EVIDENCE: 5.

Poland syndrome and breast tumor: a case report and review of the literature.

Poland syndrome is a rare congenital malformation. Hypoplasia of the sternocostal portion of the pectoralis major muscle is the most significant feature and is most frequently associated with homolateral breast hypoplasia. In this article, the authors present a case of bilateral phyllodes tumors in a 28-year-old woman with Poland syndrome and discuss (1) the relationship between the condition and breast cancer, (2) the modes of surveillance in patients with Poland syndrome, and (3) its impact on breast reconstruction.
