Adenoid cystic carcinoma of the orbit without lacrimal gland involvement and with intracranial extension: A case report.

We present a 76-year-old female with a 6-year history of decreased vision in the right eye and right-sided facial neuralgia. She had a T1 isointense and T2 isointense enhancing lesion in the right orbit and the middle cranial fossa on MRI examination. Granulomatous disease or meningioma was suspected, however, after removal, the tumor was identified by pathology as adenoid cystic carcinoma (ACC). The tumor has no radiological and clinical lacrimal grand involvement. ACC shows a slow and indolent growth pattern but is associated with poor long-term outcomes, mainly due to perineural invasion, local control failure, and distant metastasis. This case highlights the importance of a pathologic diagnosis and early intervention in similar presentations.

Survival rates of systemic interventions for psoriasis in the Western Japan Psoriasis Registry: A multicenter retrospective study.

Psoriasis affects approximately 0.3% of the Japanese population. Recently, various effective systemic drugs have become available, and the continuation of a given treatment has become critical because of the chronic nature of psoriasis. Factors affecting drug survival (the time until treatment discontinuation) in psoriasis treatment include efficacy, safety, ease of use, and patient preference. In the present study, the authors retrospectively surveyed a multifacility patient registry to determine the real-world evidence of the survival rate of systemic interventions for psoriasis treatment. Patients with psoriasis who visited 20 facilities in the Western Japan area between January 2019 and May 2020 and gave written consent were registered as study participants, and their medical history of systemic interventions for psoriasis (starting from 2010) was retrospectively collected and analyzed. The drugs investigated were adalimumab, infliximab, ustekinumab, secukinumab, ixekizumab, brodalumab, guselkumab, risankizumab, cyclosporine, and apremilast. When drugs were discontinued, the reasons were also recorded. A total of 1003 patients with psoriasis including 268 with psoriatic arthritis (PsA) were enrolled. In biologics, more recently released drugs such as interleukin 17 inhibitors showed a numerically higher survival rate in the overall (post-2010) analysis. However, in the subset of patients who began treatment after 2017, the difference in the survival rate among the drugs was smaller. The reasons for discontinuing drugs varied, but a loss of efficacy against dermatological or joint symptoms were relatively frequently seen with some biologics and cyclosporine. The stratification of drug survival rates based on patient characteristics such as bio-naive or experienced, normal weight or obese, and with or without PsA, revealed that bio-experienced, obese, and PsA groups had poorer survival rates for most drugs. No notable safety issues were identified in this study. Overall, the present study revealed that the biologics show differences in their tendency to develop a loss of efficacy, and the factors that negatively impact the survival rate of biologics include the previous use of biologics, obesity, and PsA.

Clinical characteristics of patients with psoriasis with family history: A multicenter observational study.

Previous studies on family history of psoriasis showed that patients with a family history have an earlier onset of the disease, but such studies in Japan are still limited. To elucidate the characteristics of patients with familial psoriasis, we studied the family history of patients with psoriasis using the West Japan Psoriasis Registry, a multi-institutional registry operated by 26 facilities in the western part of Japan, including university hospitals, community hospitals, and clinics. This study enrolled 1847 patients registered between September 2019 and December 2021, with 199 (10.8%) having a family history of psoriasis. Patients with a family history of psoriasis had significantly earlier onset of the disease than those without a family history. Furthermore, patients with a family history of psoriasis had significantly longer disease duration. Psoriatic arthritis (PsA) was significantly more common in patients with a family history (69/199, 34.7%) than in those without a family history (439/1648, 26.6%) (adjusted P = 0.023). A subanalysis of patients with PsA revealed a significant difference in the patient global assessment (PaGA) score in Fisher's exact test and adjusted test. The numbers of patients with PaGA 0/1 were 29 (43.3%) and 172 (39.9%) in patients with PsA with and without family history of psoriasis, respectively, whereas the numbers of patients with PaGA 3/4 were 13 (19.4%) and 145 (33.6%) in patients with PsA with and without family history of psoriasis, respectively. Other disease severity variables did not show a difference between the two groups. Our findings suggest that genetics play a larger role in the development of PsA than in the development of psoriasis vulgaris. Most cases of PsA occur in patients who already have psoriasis, therefore dermatologists should pay attention to joint symptoms, especially in patients with psoriasis who have a family history of psoriasis.

Summary of the current status of clinically diagnosed cases of Schnitzler syndrome in Japan.

BACKGROUND: Schnitzler syndrome is a rare disorder with chronic urticaria, and there is no report summarizing the current status in Japan. METHODS: A nationwide survey of major dermatology departments in Japan was conducted in 2019. We further performed a systematic search of PubMed and Ichushi-Web, using the keywords "Schnitzler syndrome" and "Japan" then contacted the corresponding authors or physicians for further information. RESULTS: Excluding duplicates, a total of 36 clinically diagnosed cases were identified from 1994 through the spring of 2022, with a male to female ratio of 1:1. The median age of onset was 56.5 years. It took 3.3 years from the first symptom, mostly urticaria, to reach the final diagnosis. The current status of 30 cases was ascertained; two patients developed B-cell lymphoma. SchS treatment was generally effective with high doses of corticosteroids, but symptoms sometimes recurred after tapering. Colchicine was administered in 17 cases and was effective in 8, but showed no effect in the others. Tocilizumab, used in six cases, improved laboratory abnormalities and symptoms, but lost its efficacy after several years. Rituximab, used in five cases, was effective in reducing serum IgM levels or lymphoma mass, but not in inflammatory symptoms. Four cases were treated with IL-1 targeting therapy, either anakinra or canakinumab, and achieved complete remission, except one case with diffuse large B-cell lymphoma. CONCLUSIONS: Since Schnitzler syndrome is a rare disease, the continuous collection and long-term follow-up of clinical information is essential for its appropriate treatment and further understanding of its pathophysiology.

Mycobacterium tuberculosis infection in psoriatic patients treated with biologics: Real-world data from 18 Japanese facilities.

Although rare, tuberculosis has been reported with biologic treatment against psoriasis in Japan, a tuberculosis medium-burden country. Mycobacterial infection often develops after a long incubation period and might not have been adequately identified in clinical trials or post-marketing surveillance. To determine the real-world incidence of tuberculosis in psoriatic patients treated with biologics, we conducted a retrospective, multicenter, observational study in 18 facilities in Western Japan. Psoriatic patients who visited a participating facility between 2010 and March 2017 and received biologic reagents were enrolled. Information on sex, age at first biologic treatment, results of interferon-γ release assay (IGRA) for Mycobacterium tuberculosis, treatment history with isoniazid, and onset of active and/or latent tuberculosis was collected. A total of 1117 patients (830 men and 287 women) were enrolled. The mean duration of biologic treatment was 3.54 years. Sixty-five patients (5.8%) showed positive IGRA results at screening. Active tuberculosis developed in two patients after the administration of tumor necrosis factor inhibitors (both involved miliary tuberculosis). Latent tuberculosis was observed in two patients treated with anti-interleukin-12/23p40 antibody. The incidence rate of tuberculosis, including latent tuberculosis, in this survey was 0.36%. Although the incidence rate of tuberculosis was low considering the observation period of biologic treatment, active tuberculosis was found in both the screening-negative group and a screening-positive subject after isoniazid prophylaxis (both miliary tuberculosis), concluding that negative screening or isoniazid treatment does not always assure that an individual has no tuberculosis. Hence, dermatologists still need to pay careful attention to tuberculosis at every patient visit.

Fluorescence navigation with indocyanine green for detecting sentinel nodes in extramammary Paget's disease and squamous cell carcinoma.

The radioisotope navigation method, which has usually been used for identification of sentinel nodes, is less useful in locating sentinel nodes close to primary lesions in cases of extramammary Paget's disease because of overlapping radioactivity from the primary site. We applied fluorescence navigation with indocyanine green (ICG) in two patients with skin cancer to cover this defect. The use of a charge-coupled device camera enabled real-time visualization of dynamic lymph flow without skin incision. The inguinal skin over the identified sentinel node with a handheld gamma probe was in accordance with the point detected by ICG fluorescence in a patient with squamous cell carcinoma of the foot. Sentinel node biopsy using fluorescence navigation with ICG proved to be easy and reliable.
