RESUMO
Skin adhesives have become standard in wound closure as alternatives to traditional sutures or as sterile occlusive dressings after surgery of all types. The literature is replete with case reports of contact dermatitis following exposure to cyanoacrylate-based adhesives, such as 2-octyl cyanoacrylate. Nonetheless, it has been the impression of the senior author and others that the incidence of allergic and/or contact dermatitis is much higher than commonly considered. The authors prospectively studied 102 consecutive patients who underwent breast surgery performed by the senior author with 2-octyl cyanoacrylate placed over incisions as an occlusive dressing. Two patients with a known glue allergy did not receive cyanoacrylate at surgery but were scratch tested to confirm the diagnosis. All patients were followed postoperatively. Twelve patients went on to develop significant dermatitis postoperatively after glue placement. Cyanoacrylate was confirmed as the cause of all rashes by allergy scratch testing for a total incidence of 14 percent (14 patients). Given the popularity of cyanoacrylate products across emergency rooms, clinics, and operating rooms, awareness of the true incidence of these reactions may caution against their use in the future. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, IV.

Subungual exostosis is an uncommon bony tumor of the distal phalanx most often seen on the hallux. Although this lesion is completely benign, it must be distinguished from a number of other subungual tumors, both benign and malignant. Radiography of the digit is a noninvasive test that should be part of the initial workup whenever subungual exostosis is in the differential diagnosis. Once identified, surgical removal of the exostosis generally is both effective and well tolerated. We present a case of subungual exostosis that was discovered incidentally during a full-body skin examination. We also review the pertinent clinical and histopathologic findings, diagnosis, and treatment of this entity.

We present the case of a bone marrow transplant patient who was diagnosed with crusted scabies but did not respond to the usual approach with topical permethrin and ivermectin. The Centers for Disease Control and Prevention were contacted and suggested a 7-dose regimen of ivermectin. The patient started to improve remarkably after the third dose, and the skin eruption was resolved after 7 doses. This case supports the use of a more prolonged course of oral ivermectin for crusted scabies in those who fail the conventional approach.

Hepatitis C (HCV) is the most common cause of chronic liver disease and hepatocellular carcinoma, as well as the leading indication for liver transplantation in the Western world. For many patients, cutaneous manifestations may be the only, the earliest, or the most apparent sign of the underlying infection. The dermatologic manifestations of HCV infection are reviewed.

Hyperandrogenism in women can be caused by various conditions, the most prevalent of which is polycystic ovary syndrome. Common dermatologic manifestations of hyperandrogenism include hirsutism, acne, acanthosis nigricans, and androgenic alopecia. Hirsute women often have increased activity of 5 alpha-reductase, the enzyme that converts the androgen testosterone to its active metabolite, in hair follicles. Likewise, androgens affect the formation of acne by increasing sebum production from sebaceous glands in the skin. The diagnosis of polycystic ovary syndrome includes a complete history, physical examination with emphasis on evidence of androgen excess, and appropriate laboratory investigation to exclude other causes of hyperandrogenism. Treatments for the dermatologic conditions of hyperandrogenism include lifestyle modification, oral contraceptives, antiandrogens, and insulin-sensitizing medications.
