Nail psoriasis is a chronic condition characterized by nail dystrophy affecting the nail matrix and bed. The severity of nail psoriasis is commonly assessed using the Nail Psoriasis Severity Index (NAPSI), which evaluates the characteristics and extent of nail involvement. Although the NAPSI is numeric, reproducible, and simple, the assessment process is time-consuming and often challenging to use in real-world clinical settings. To overcome the time-consuming nature of NAPSI assessment, we aimed to develop a deep learning algorithm that can rapidly and reliably evaluate NAPSI, thereby providing numerous clinical and research advantages. We developed a dataset consisting of 7054 single fingernail images cropped from images of the dorsum of the hands of 634 patients with psoriasis. We annotated the eight features of the NAPSI in a single nail using bounding boxes and trained the YOLOv7-based deep learning algorithm using this annotation. The performance of the deep learning algorithm (DLA) was evaluated by comparing the NAPSI estimated using the DLA with the ground truth of the test dataset. The NAPSI evaluated using the DLA differed by 2 points from the ground truth in 98.6% of the images. The accuracy and mean absolute error of the model were 67.6% and 0.449, respectively. The intraclass correlation coefficient was 0.876, indicating good agreement. Our results showed that the DLA can rapidly and accurately evaluate the NAPSI. The rapid and accurate NAPSI assessment by the DLA is not only applicable in clinical settings, but also provides research advantages by enabling rapid NAPSI evaluations of previously collected nail images.

Background: Inflammatory dermatological conditions, including psoriasis, lichen planus, eczema, and alopecia areata, are frequently accompanied by nail findings and can have a significant impact on quality of life. Biologic and small-molecule medications have been approved over the past several decades in treating patients with these inflammatory nail disorders. They may be used in conjunction with longstanding mainstays of treatment (topical and intralesional corticosteroids, topical vitamin D3 analogs).

Acrodermatitis continua of Hallopeau is a rare form of pustular psoriasis affecting the acral fingers and toes, characterized by recurrent eruptions of sterile pustules that lead to significant pain and potentially irreversible destruction of the nail apparatus. Symptoms are often refractory to topical and systemic therapies for psoriasis. This case report presents a healthy 23-year-old female with severe acrodermatitis continua of Hallopeau, destructing all 10 fingernails.
