Soft tissue extramedullary plasmacytoma.

We present the uncommon case of a subcutaneous fascia-based extramedullary plasmacytoma in the leg, which was confirmed by the pathology report and followed up until its remission. We report the differential diagnosis with other more common soft tissue masses. Imaging findings are nonspecific but are important to determine the tumour extension and to plan the biopsy.

Leiomiosarcoma de vesícula seminal. Presentación de un caso

Aims: Leiomyosarcoma of the seminal vesicle is extremely rare and very little information is available on how best it should be treated. The advantage of adjuvant therapy treatment is unclear. Methods and results: We report a case of leiomyosarcoma arising from the seminal vesicle in a 65-year-old man. Conclusion: Leiomyosarcoma is a malignant neoplasm with a poor prognosis and radical surgical excision is the treatment of choice.

What is the presentation of renal angiomyolipomas?

Renal angiomyolipomas (AMLs) are commonly benign tumours formed by fat, blood vessels and non-striated muscle, which tend to be associated with neuroendocrine syndromes, or turn up sporadically.

A woman with reddish nodule on the skin of the breast.

A 54-year-old woman presented a peri-areolar nodule located in the skin of the right breast. Clinical examination showed a 6 x 5 cm exophytic, lobed, ulcerated, and bleeding nodule. The patient reported that the tumor had grown gradually over a period of 3 months. The patient had been diagnosed 8 years prior to presentation with infiltrating ductal carcinoma of the right breast (pT2NO). This tumor was treated with partial mastectomy (conservative surgery) and lymph node dissection, then subsequently received 30 tangent field radiotherapy sessions to the breast for a total dose of 45 Gy. The rest of her cutaneous exam was normal. There was no family history of any similar tumor.

Osteosarcoma extraóseo en extremidad inferior

INTRODUCTION: Extraoseus osteosarcoma is a rare tumor confined in soft tissues but with histological features similar to bone osteosarcoma. CLINICAL CASE: We report the case of a young male affected extraosseous osteosarcoma. A detailed analysis of the clinical symptoms and evolution from the beginning of the process to the death of the patient, three years later, is performed. DISCUSSION: The different types of treatment and prognostic factors involving this disease are discussed CONCLUSIONS: Radical surgery followed by chemotherapy is the preferred form of treatment in extraosseus osteosarcoma.The latest advances in chemotherapy have improved the prognosis in this type of tumor

Artrodesis de tobillo: resultados comparativos de diferentes técnicas

INTRODUCTION: Ankle arthrodesis in an intervention that may be performed using a variety of surgical approaches. The joint may be stabilized using diferent systems, with or without bone graft. MATERIAL AND METHODS: Retrospective study that collected the results of 40 patients who underwent ankle arthrodesis; the complications that arose were analyzed, results according to the AOFAS clinical rating system, global patient satisfaction and the relationship with the articular approach route, the !xation system or the usage of grafts.RESULTS: 55% of the patients presented one or more complication that motivated a total of 12 re-interventions in 10 patients (excludes removal of osteosynthesis material). The absence of consolidation, which required a new arthrodesis was more frequent in patients where osteosynthesis was not used (two out of three cases) than in those using screws (four out of 24 cases), while there was no register of this in 13 patients in which intramedullary pin. The use of the distal extreme of the fibula or the iliac crest as bone graft has failed to improve the consolidation. Arthroscopic approaches avoid the appearance of soft tissue complications, although the consolidation disorders were more frequent. The average score on the AOFAS clinical rating system was 56.4±21.2 and 55% of the patients were satisfied. CONCLUSIONS: Although the case histories fail to provide significant results, it is a demanding intervention, with an elevated complication rate. Intramedullary pins seem to favor improved consolidation.

Fractura bilateral de calcáneo en edad pediátrica. A propósito de un caso

OBJECTIVE: Propose and debate the treatment management for unusual traumatic pathology, both due to the age of the patient and the bilateral location. CLINICAL CASE: Bilateral calcaneal fracture in a ten year old male, after falling three meters to land on his heels. Examination revealed pain and swelling at that level, with no distal neurovascular alterations. After the clinical study, x-rays were taken, as well as a CAT scan which revealed a complex fracture of both calcanei. After 72 hours and verifying that the soft tissue was in optimal condition, the left calcaneus was immobilized with a closed cast while the right was trans!xed with a Steinmann pin following the Essex-Lopresti technique, achieved under scope to attain an acceptable reduction of the fracture and the congruency of all a"ected joints.

Remisión completa precoz de tumoraciones cardiacas múltiples sugestivas de rabdomiomas cardiacos

We present the case of a patient with an echocardiographic diagnosis of suspected multiple rhabdomyomas with spontaneous, complete early remission.

Superficial Acral Fibromyxoma involving the nail's apparatus. Case report and literature review.

Superficial Acral Fibromyxoma is a rare tumor of soft tissues. It is a relatively new entity described in 2001 by Fetsch et al. It probably represents a fibrohistiocytic tumor with less than 170 described cases. We bring a new case of SAF on the 5th toe of the right foot, in a 43-year-old woman. After surgical excision with safety margins which included the nail apparatus, it has not recurred (22 months of follow up). We carried out a review of the location of all SAF published up to the present day.

Keratotic Nodule on The Heel: A Quiz.

A 51-year-old man, with a medical history of medullary thyroid carcinoma excised under thyroxine treatment presented with a painful enlarging lesion on his right heel since one year. A 3-cm diameter, greyish, infiltrated nodule with spicules was seen on physical examination (Fig. 1a). A 5-mm surgical excision was made and a total skin graft was used for reconstruction. Histopathology of the total resected tumour revealed pseudoepitheliomatous hyperplasic epidermis and a proliferation located between rete ridges, dermis and superficial hypodermis (Fig. 1b). The proliferation was composed of nets and cordons of cells with granular and abundant PAS-positive cytoplasm. Immunostains showed cytoplasmic positivity for s100 and inhibin (Fig. 1c). Three years later the patient is asymptomatic.

Structured intermittent interruption of chronic HIV infection treatment with highly active antiretroviral therapy: Effects on leptin and TNF-alpha.

The changes in nutritional parameters and adipocytokines after structured intermittent interruption of highly active antiretroviral treatment of patients with chronic HIV infection are analyzed. Twenty-seven patients with chronic HIV infection (median CD4+ T cell count/microl: nadir, 394; at the beginning of structured interruptions, 1041; HIV viral load: nadir, 41,521 copies/ml; at the beginning of structured interruptions <50 copies/ml; median time of previous treatment: 60 months) were evaluated during three cycles of intermittent interruptions of therapy (8 weeks on/4 weeks off). CD4+ T cell count, HIV viral load, anthropometric measures, and serum concentrations of triglycerides, cholesterol, leptin, and tumor necrosis factor and its soluble receptors I and II were determined. After the three cycles of intermittent interruptions of therapy, no significant differences in CD4+ T cell count/microl, viral load, or serum concentrations of cholesterol or triglycerides with reference to baseline values were found. A near-significant higher fatty mass (skinfold thicknesses, at the end, 121 mm, at the beginning, 100 mm, p = 0.100), combined with a significant increase of concentration of leptin (1.5 vs. 4.7 ng/ml, p = 0,044), as well as a decrease in serum concentrations of soluble receptors of tumor necrosis factor (TNFRI, 104 vs. 73 pg/ml, p = 0.022; TNFRII 253 vs. 195 pg/ml, p = 0.098) were detected. Structured intermittent interruption of highly active antiretroviral treatment of patients with chronic HIV infection induces a valuable positive modification in markers of lipid turnover and adipose tissue mass.

Different profiles of immune reconstitution in children and adults with HIV-infection after highly active antiretroviral therapy.

BACKGROUND Recent advances in characterizing the immune recovery of HIV-1-infected people have highlighted the importance of the thymus for peripheral T-cell diversity and function. The aim of this study was to investigate differences in immune reconstitution profiles after highly active antiretroviral therapy (HAART) between HIV-children and adults. METHODS HIV patients were grouped according to their previous clinical and immunological status: 9 HIV-Reconstituting-adults (HIV-Rec-adults) and 10 HIV-Reconstituting-children (HIV-Rec-children) on HAART with viral load (VL) or=500 cells/microL at least during 6 months before the study and CD4+
