The use of anaplastic lymphoma kinase antibodies (ALK1) as a diagnostic aid has expanded since becoming a routinely available immunohistochemical stain. Because the skin may be the site of a wide variety of hematolymphoid and fibroblastic proliferations, dermatopathologists commonly use ALK1 as part of a broader staining panel in diagnosing soft tissue and cutaneous hematolymphoid neoplasms. Furthermore, new entities and differential diagnostic contexts are emerging, which broaden the utility of ALK1 immunohistochemistry. We review the expanding role of ALK1 immunohistochemistry in contemporary dermatopathology. © 2013 Lippincott Williams & Wilkins.

Chronic constipation is a frequently complained condition in clinical practice and may be primary (idiopathic) or due to secondary causes. The definition of the various forms of constipation is presently made according to the Rome III criteria, which recently incorporated also specific diagnostic algorithms. The diagnosis of constipation relies on the patient's history, including use of drugs, physical examination, and specific investigations (transit time, anorectal manometry, balloon expulsion test, defecography). These will often be useful to start a targeted therapeutic schedule that may include fibres, laxatives, biofeedback training and, in extreme cases, a surgical approach. This review will analyse the clinical and diagnostic aspects of chronic constipation in adult patients, with emphasis on recent therapeutic approaches. © 2011 SIMI.

The practice of self-injection of anabolic steroids (AS) in bodybuilders is common. AS are not the only materials used by bodybuilders for muscle augmentation or image enhancement. Other materials, for example, plant oils, silicon, Vaseline, and paraffin are also injected either in a pure form or mixed with AS. Muscle bulking is the main aim. However, bodybuilders undergo illicit injections for cosmetic, therapeutic, and sexual purposes. Even though the practice of unsupervised injection is probably common in the sports community, site-specific complications are underreported in the medical literature and mostly limited to case reports. Complications can be clinically and pathologically challenging because some can be confused with nonneoplastic and, more important, with neoplastic lesions. Bodybuilders are reluctant to disclose information because of stigma and legal issues. This study attempts to correlate the clinical manifestations and histomorphological features of different injected materials used for different purposes by bodybuilders in our region. A series of 11 cases out of 9 male bodybuilders was studied. A variety of clinical presentations and histological tissue reactions was identified, with some overlapping features between some cases. We identified 5 basic tissue reaction patterns depending on the injected materials, site, and duration of injection. Certain histological features provide useful hints in the absence of prior knowledge of injection history. However, in other cases, a retrospective enquiry by clinicians is warranted to avoid pitfalls. The medical and sports community should be aware of these injection-site complications. Bodybuilders should be discouraged from this practice by implementing appropriate educational and legislative measures. © The Author(s) 2014.

Currently, urogenital complaints are among the most common problems encountered by family practitioners, gynecologists, and dermatologists. In response to the intricacy of vulvar disorders, the International Society for the Study of Vulvovaginal Disease was created to facilitate the exchange between clinicians and pathologists involved in the care of these patients. Recent classifications for inflammatory disorders and intraepithelial neoplasm have been proposed. In addition, vulvar skin biopsies are the most common source of intradepartmental consultation during dermatopathology sign-out. The purpose of this article is to review the various inflammatory dermatoses of the vulva and to update readers with new advances regarding these entities. © 2014 Lippincott Williams &Wilkins.

Renal involvement is an unusual but significant Behcet́s disease (BD) complication and AA amyloidosis appears to be the most common etiology. IL-6 is a pro-inflammatory cytokine with an important role in AA amyloidosis development. Tocilizumab (TCZ) is a humanized anti-IL-6 receptor antibody that has emerged as an effective and specific treatment in AA amyloidosis secondary to chronic inflammatory disorders. We report on a patient diagnosed with BD who developed nephrotic syndrome caused by renal AA amyloidosis with an excellent response to TCZ therapy. Copyrigh © Informa Healthcare USA, Inc.
