Jambusaria-Pahlajani and coauthors identify risk factors for poor outcomes in cutaneous squamous cell carcinoma and evaluate the 2010 American Joint Committee on Cancer tumor (T) staging system’s ability to stratify occurrence of these outcomes.
Jaimes and colleagues describe and analyze the clinical and dermoscopic characteristics of desmoplastic melanoma as a function of pathologic subtype and phenotypic traits.
Wolf et al measure the performance of 4 smartphone applications that evaluate photographs of skin lesions using the histologic finding as the reference standard.
To test if the relative proportions of MRSA and MSSA were changing or stable in an outpatient clinic, Zabielinski et al studied 387 skin culture S aureus isolates obtained annually between 2005 and 2010 and monthly in the first half of 2011. Relative proportions of MRSA and MSSA isolates were measured and antibiotic sensitivity profiles determined.
To confirm observations by Sulzberger et al in 1947 on the blockage of sweat ducts in atopic dermatitis, Haque et al examined biopsy specimens submitted as diagnostic of various inflammatory diseases and with a secondary differential diagnosis of eczema. Each specimen was examined for ductal obstruction after staining with H&E, PAS, and Gram stain.
Arzberger and coauthors evaluated the ability of reflectance confocal microscopy to differentiate between balanitis and carcinoma in situ compared with the gold standard histopathologic methods.
Soltani-Arabshahi and colleagues describe a 19-month-old girl with a 6-month history of pruritus localized to the left side of the neck, shoulder, arm, and elbow, who had a spinal tumor in the cervical spinal cord. Her pruritus improved rapidly after surgical removal of the tumor.
Belani et al describe 2 patients having neutrophilic urticaria with systemic inflammation (NUSI) without known connective tissue disorder or malignancy. They propose the term NUSI to help classify a previously undefined multisystemic inflammatory entity likely mediated by interleukin 1.
Requena et al describe the clinical, histopathologic, and immunohistochemical features of 2 cases of cutaneous epithelioid sarcomalike hemangioendothelioma.
