ABSTRACT

Ustekinumab is a biologic agent with Food and Drug Administration approval for the treatment of moderate-to-severe plaque psoriasis, psoriatic arthritis, ulcerative colitis, and Crohn's disease. It functions to inhibit the p40 subunit common to both interleukin-12 and interleukin-23. These pro-inflammatory cytokines are implicated in autoinflammatory and autoimmune disorders, but they also play an important role in cell-mediated immunity against viral, bacterial, and fungal pathogens. Therefore, antagonism of interleukin-12 and interleukin-23 by ustekinumab may increase the risk of human papillomavirus infection or reactivation which can lead to the development of verrucae. To the best of our knowledge, there is only one published report of disseminated verrucosis secondary to ustekinumab treatment for psoriasis. Here, we present the first case report of ustekinumab-induced disseminated verrucosis occurring in the setting of treatment for Crohn's disease.

ABSTRACT

Cutaneous endometriosis is an uncommon dermatologic disorder predominantly seen in young women. Most commonly, it presents within a region of a previous surgical scar, often in relation to a gynecologic procedure on the abdomen or in close proximity to the umbilicus. The typical clinical presentation is that of papules or nodules with monthly cyclical pain and size variation. Histologically, the lesions are composed of endometrial stroma and glands. The pathophysiology is not well understood but is believed to be due to metastasis or seeding of endometrial cells. When this uncommon disorder occurs outside of the most typical clinical setting, it may cause some diagnostic difficulty. In this report, we present the first known case of cutaneous endometriosis on the eyelid.

ABSTRACT

INTRODUCTION: Isotretinoin, previously marketed as Accutane®, is an oral retinoid medication that is used to treat acne and other cutaneous disorders. Although the data is conflicting, previous reports suggest a causal relationship between isotretinoin and depression. When reviewing these previous reports, many patients who were diagnosed as "depressed" did not undergo a thorough psychiatric evaluation and/or were not diagnosed according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM). These patients reported agitation, irritability, sleep disturbances, and aggression. We hypothesize that some patients previously reported as "depressed" may have been "misdiagnosed" and were actually experiencing symptoms of mania, mixed mood (depression and mania at the same time), or psychosis. EVIDENCE ACQUISITION: An Ovid Medline and PubMed literature search of English language articles was performed using the keywords "isotretinoin", "retinoids", "mood", "psychiatric", "depression", "elevation", "bipolar", and "psychosis". Eleven case reports, three case series, three retrospective chart reviews, five drug registries, and two prospective studies were reviewed. EVIDENCE SYNTHESIS: We found that many of the patients labeled as "depressed", had signs of activation, agitation, elevated mood, and psychosis. We believe that many of these patients were most likely having manic or mixed mood episodes. These symptoms appeared to be more prevalent in patients with a personal or family history of mental illness. CONCLUSIONS: Isotretinoin may cause mood instability in both directions - depression and mania - especially in a predisposed population. With this in mind, we urge clinicians prescribing isotretinoin to focus on all psychiatric symptoms (not just depression) including mania, mixed mood, and psychosis, paying particular attention to individuals who have a personal or family history of psychiatric disease.
