Epithelioma of Malherbe: new ultrasound patterns

<p>Abstract</p> <p>Backround</p> <p>Calcifying epithelioma of Malherbe, or Pilomatricoma, is considered an uncommon cutaneous neoplasia, normally occurring in children as a solitary, firm, asymptomatic, hard, subcutaneous, slowly growing nodule on the face, neck, or proximal upper extremity. In literature, two Pilomatricoma ultrasound patterns are described: the totally calcified nodule and the hypoechoic nodule with internal calcific foci. High frequency ultrasound has not yet been applied for routine diagnosis of Pilomatricoma. The aim of the study was to retrospectively identify specific ultrasound features.</p> <p>Methods</p> <p>We retrieved 124 histologically Pilomatricoma cases: 28 patients with 32 lesions were preoperatively evaluated with ultrasound.</p> <p>Results</p> <p>22/32 have shown a solid formation, hypoechoic, with a sharp outline. Of these 22, 10 lesions were completely calcifying and 12 partially calcified. In 3/32 lesions with uncertain diagnosis, ultrasounds showed a complex/mixed pattern with pseudo-fluid areas and microspots. 7/32 lesions with US different diagnosis included 3 complex lesions, 2 cystic lesions and 2 solid nodular lesions.</p> <p>Conclusion</p> <p>In addition to well-known ultrasound patterns (completely calcified and partially calcified) we identified three new, not yet described, patterns that constitute the 31% of the cases: complex, pseudocistyc and pseudotumoral.</p

Merkel cell polyomavirus in Merkel cell carcinoma of Italian patients

<p>Abstract</p> <p>Background</p> <p>Merkel cell carcinoma (MCC) is a rare but very aggressive human malignancy of elderly or immunosuppressed patients. Clonal integration of a new human polyomavirus, the Merkel cell polyomavirus (MCPyV), has been reported in MCC patients. The main objective of the study was the detection of MCPyV and viral expression in clinical samples of Italian patients who were diagnosed MCC.</p> <p>Findings</p> <p>DNA and RNA were extracted from nine MCCs to detect the presence of MCPyV. Viral large T gene (LT1 and LT3), and viral capsid gene (VP1) were detected by polymerase chain reaction (PCR) based methods, and the amplified PCR products were subjected to direct sequencing. The presence of viral T antigen and/or viral capsid DNA sequences was demonstrated in eight of the nine MCC lesions, whereas RNA transcripts were detected in three MCCs.</p> <p>Conclusions</p> <p>These findings indicate a potential role of MCPyV in the pathogenesis of at least a subset of MCCs.</p
