Comparative Study
Association of Delays in Surgery for Melanoma With Insurance Type.
Timely receipt of treatment for cancer is an important aspect of health care quality. It is unknown how delays of surgery for melanoma vary by insurance type. ⋯ Surgical treatment delays were common but were less prevalent in patients diagnosed or surgically treated by a dermatologist. Medicaid patients experienced the most surgical delays. A reduction in delays in melanoma surgery could be achieved through better access to specialty care and cross-disciplinary coordination.

Hailey-Hailey disease is a severe genetic blistering disease of intertriginous skin locations that can lead to poor quality of life and increased morbidities. Multiple therapies are available with inconsistent outcomes and potentially severe adverse effects. ⋯ We present herein 3 cases of patients with severe Hailey-Hailey disease treated with low-dose naltrexone who achieved clinical resolution of symptoms. The success of these cases suggests low-dose naltrexone as a novel therapy for Hailey-Hailey disease. The possible mechanism may involve low-dose naltrexone influencing opioid or toll-like receptor signaling to improve calcium mobilization and improve keratinocyte differentiation and wound healing. Future studies are needed to clarify the mechanism and to define the role of low-dose naltrexone for treatment of Hailey-Hailey disease.

Familial benign pemphigus, or Hailey-Hailey disease (HHD), is a rare and debilitating genetic dermatosis characterized by chronic, recurrent vesicles, erosions, and maceration in flexural areas. Despite the reported therapeutic modalities, such as topical and systemic corticosteroids, systemic immunomodulators, topical and systemic retinoids, and laser, HHD can still be markedly difficult to control. ⋯ Low-dose naltrexone may represent a low-cost and low-risk alternative or adjunct in the treatment of HHD.

Pigmented facial macules on photodamaged skin are a clinical, dermoscopic, and histopathologic challenge. ⋯ Reflectance confocal microscopy improves LM diagnosis in photodamaged skin with good histopathologic correlation although false-positive and false-negative cases exist. False-positives obtained with RCM in photodamaged skin are due to the presence of basal melanocyte hyperplasia and intraepidermal Langerhans cells. Histopathologic features of these lesions sometimes are not enough for a definite diagnosis and immunohistochemical studies may be required.
