Background: Reconstructing defects on the nose can be challenging. The bilobed transposition flap and the nasalis-based V to Y (NBVY) flaps can be excellent repair options, each with their own advantages and disadvantages. Objective: To compare bilobed and NBVY flap scar appearances, postoperative complications, scar revision rates, flap sizes,...

There is a lack of data characterizing tumors located within male facial hair subunits and determining if terminal hair growth obscures tumor detection, thus leading to a delay in diagnosis. Our objective was to evaluate the difference in cutaneous tumor size in men who had facial hair compared to men without facial hair. This retrospective chart r...

Extramammary Paget disease is an intraepidermal adenocarcinoma, most often limited to the epidermis, with typical cases affecting genital skin. When limited to the epidermis, primary extramammary Paget disease is not life-threatening, but invasive disease may portend a poor prognosis. Surgical excision remains the mainstay of treatment of extramamm...

Background: Mohs micrographic surgery (MMS) has been used effectively to treat invasive melanoma. Objective: To further study the safety and efficacy of MMS in the treatment of invasive melanoma. Methods and materials: A retrospective cohort study evaluated 123 melanomas excised using MMS with MART-1 immunostain. Local recurrence, metastasis,...

We describe deep granuloma annulare (DGA) of the forehead mimicking inflamed cysts. Reactive inflammation and sterile purulent drainage may be an underrecognized feature of DGA.

Background: Cutaneous T-cell lymphomas (CTCL) are skin malignancies including mycosis fungoides (MF) and CD30(+) lymphoproliferative disorders (LPD). In early disease, CTCL can be difficult to diagnose, especially in MF for which there is no reliable diagnostic marker. MF/CTCL have increased expression of thymocyte selection-associated HMG box pro...

Petrified ear is the transformation of normal, flexible auricular cartilage into rigid, immobile auricular cartilage due to abnormal calcification or ossification. Etiologies of petrified ear include tissue injury, systemic endocrine diseases, congenital disorders, or petrified ear of unknown origin. We present a case of a 69-year-old male with a o...

Background: Existing predictive models for lung cancer focus on improving screening or referral for biopsy in general medical populations. A predictive model calibrated for use during preoperative evaluation of suspicious lung lesions is needed to reduce unnecessary operations for a benign disease. A clinical prediction model (Thoracic Research Ev...

Lung cancer predictive models, such as the Mayo model (Swensen, 1997), that are used for screening and referral to surgery are based on only traditional variables and are outdated. Clinical information such as FEV1, FDG-PET and lesion growth increasingly are used in treatment decisions. This information needs to be incorporated into our clinical pr...

Background: Auditory processing abnormalities are reported frequently among clinical descriptions and experimental findings regarding autism spectrum disorders (ASDs). Failure to orient to environmental sounds, including to respond to one’s name, is a common feature in ASD, and difficulties with sound localization could contribute to auditory orien...
