“…Subungual hematomas may show hyperechoic reflective borders and displace the nail plate and the nail bed tissue (Figures 12 and 13). This is a relevant difference from melanoma, which commonly shows internal hypervascularity due to tumoral angiogenesis 50,51 . However, the diagnosis of in situ melanoma could be challenging to make with ultrasound because this detection would be among the limitations of the technique 55 …”

“…The chronic inflammation with granulomatous tissue can involve the nail matrix and generate alterations in the nail bed and nail plate. Importantly, ultrasound can support the differential diagnosis of granulomas with tumors of the nail bed 50,51,64 . On ultrasound imaging, there is hypoechoic thickening of the nail bed, sometimes with a pseudonodular appearance.…”

Chronic exposure to trauma, friction, or extreme conditions can generate cutaneous or ungual lesions in sports and certain occupations. Although some of these dermatologic conditions are diagnosed with a naked-eye examination, there are cases in which the provision of the underlying anatomic alterations can be helpful for the diagnosis and management. In comparison with computed tomography or magnetic resonance imaging, ultrasound has the highest axial resolution, which is critical for the observation of anatomic changes in the skin and nail. We review the ultrasound characteristics of frequent cutaneous and ungual lesions related to sports and occupations with a clinical correlation. The ultrasound features in some particular conditions such as "biker's and surfer's panniculitis," "fiddler's neck," piezogenic papules, and lipoatrophy semicircularis, among others, are discussed.

Digital Myxoid Cysts: Correlation of Initial and Long-Term Response to Steroid Injections

et al. 2021

View full text Add to dashboard Cite

BACKGROUNDDigital mucous cysts (DMCs) are benign myxoid pseudocysts that develop on the distal interphalangeal joint's lateral or dorsal aspects. Management consists either of a surgical approach, conservative therapy, or simple follow-up.OBJECTIVETo correlate the initial and long-term response with clinical and ultrasound parameters in DMCs treated with intralesional steroids as first-line therapy.METHODSA single-center prospective open-label study recruited 15 patients affected by DMCs, who had been treated with a cycle of up to 3 steroid injections at a 6 to 9 week time interval.RESULTSAt the first follow-up visit, 53.3% of patients were cleared of DMCs, achieving a complete response, whereas 46.7% experienced a >30% decrease in their DMC volume, and were considered partial responders. After 1 year of follow-up, the cure rate decreased to 40%, and the recrudescence rate was 27.3%. Clinical and sonographic characteristics that positively correlated with a maintained complete response at follow-up were as follows: young age, absence of osteophytes, low volume, complete clearance at T1, and short disease duration (p < .05).CONCLUSIONIntralesional steroid therapy is an easy approach for DMC, with minimal side effects; identifying predictive hallmarks is useful to offer a straightforward surgical treatment to patients who have nonresponder characteristics.

The nail unit is a unique skin appendage, capable of mounting only a limited number of reaction patterns to a variety of insults. This makes it difficult to diagnose many nail conditions based on clinical features alone. Thus, diagnostic modalities have an important role to play in nail disorders. Emphasis is placed on non-invasive diagnostic methods, of which, radiological imaging forms an important part; however, it is a field largely under-explored with very few studies and reports available in the literature. This could be due to the problems encountered in nail unit radiology including its small size, complex anatomy, requirement for special high-frequency probes to reliably evaluate superficial structures, and non-familiarity with nail unit radiological features even amongst trained radiologists. Nevertheless, it plays a useful role in diagnosing nail disorders (especially tumors), localizing the changes, exploring differential diagnoses, estimating prognosis, and planning management. This article is aimed at collating scientific data pertaining to various radiological modalities used in the diagnosis of nail diseases. The advantages and limitations of various imaging techniques used for evaluating the nail unit, including digital radiographs, high-frequency ultrasound, ultrasound doppler (USD), computed tomography (CT), and magnetic resonance imaging (MRI), are discussed in the first part. The second part will discuss the features of common and uncommon nail diseases.
