Cutaneous manifestations of tuberous sclerosis.

Abstract: Purpose: To describe a case of periungual masses probably related to tuberous sclerosis and to review the literature regarding tuberous sclerosis, including the historical, clinical, and diagnostic aspects. Also discussed is the long-term follow-up of the disease. Methods: Report of a case of periungual masses secondary to tuberous sclerosis and review of the literature from 1999 to 2009, with the use of MEDLINE (National Library of Medicine). Results: I describe a case of periungual masses occurring as a result of tuberous sclerosis. A literature review confirms periungual masses associated with tuberous sclerosis in most cases. Also, the observance of cutaneous manifestations is most helpful in the diagnosis of this disorder. Conclusion: Tuberous sclerosis is an uncommon disorder, which has a variable clinical presentation. Tuberous sclerosis is associated with seizures and mental retardation. In the absence of these 2 signs/symptoms, physicians should still consider the diagnosis when presented with varied dermatologic conditions.

Association of Magnetic Resonance Imaging and a 12-Gene Expression Assay with Breast Ductal Carcinoma in Situ Treatment

Abstract: Importance Advanced diagnostics, such as magnetic resonance imaging (MRI) and gene expression profiles, are potentially useful to guide targeted treatment in patients with ductal carcinoma in situ (DCIS). Objectives To examine the proportion of patients who converted to mastectomy after MRI and the reasons for those conversions and to measure patient adherence to radiotherapy guided by the 12-gene DCIS score. Design, Setting, and Participants Analysis of a prospective, cohort, nonrandomized clinical trial that enrolled women with DCIS on core biopsy who were candidates for wide local excision (WLE) from 75 institutions from March 25, 2015, to April 27, 2016, through the Eastern Cooperative Oncology Group–American College of Radiology Imaging Network trial E4112. Interventions Participants underwent breast MRI before surgery, and subsequent management incorporated MRI findings for choice of surgery. The DCIS score was used to guide radiotherapy recommendations among women with DCIS who had WLE as the final procedure and had tumor-free excision margins of 2 mm or greater. Main Outcomes and Measures The primary end point was to estimate the conversion rate to mastectomy and the reason for conversion. Results Of 339 evaluable women (mean [SD] age, 59.1 [10.1] years; 262 [77.3%] of European descent) eligible for WLE before MRI, 65 (19.2%; 95% CI, 15.3%-23.7%) converted to mastectomy. Of these 65 patients, conversion was based on MRI findings in 25 (38.5%), patient preference in 25 (38.5%), positive margins after attempted WLE in 10 (15.4%), positive genetic test results in 3 (4.6%), and contraindication to radiotherapy in 2 (3.1%). Among the 285 who had WLE performed after MRI as the first surgical procedure, 274 (96.1%) achieved successful breast conservation. Of 171 women eligible for radiotherapy guided by DCIS score (clear margins, absence of invasive disease, and score obtained), the score was low ( Conclusions and Relevance Among women with DCIS who were WLE candidates based on conventional imaging, multiple factors were associated with conversion to mastectomy. This study may provide useful preliminary information required for designing a planned randomized clinical trial to determine the effect of MRI and DCIS score on surgical management, radiotherapy, overall resource use, and clinical outcomes, with the ultimate goal of achieving greater therapeutic precision.

Primary cutaneous cryptococcosis in a lung transplant recipient.

Abstract: :Cryptococcal skin lesions are found in 10 to 15% of patients with disseminated cryptococcosis. Primary skin inoculation by Cryptococcus neoformans is rare but has been reported. We report the first known case of primary cutaneous cryptococcosis in a lung transplant recipient. Our patient, a
