“…Magnetic resonance imaging (MRI) is an imaging technology using non‐ionizing radiofrequency radiation inside a strong magnetic field to detect protons in hydrogen atoms that is particularly useful to study soft tissue. We found five studies that evaluated MRI in onychomatricoma, and they showed a low signal uptake for the portion that affects the nail matrix and a high signal uptake for the tumoral projections . Tumoral digitations into the nail plates appeared with a Y‐shape and with high‐intensity signal, probably due to their higher concentration of water than the surrounding nail.…”

Onychomatricoma is a rare tumour that derives from the nail matrix and grows within the nail plate. The clinical presentation can mimic many other tumours and conditions, and surgical biopsy and histopathological examination are necessary to confirm the diagnosis. As nail surgery is a painful experience for the patient and sometimes can leave permanent onychodistrophy, more precise preoperative diagnosis is needed to distinguish onychomatricoma from other nail diseases more accurately and to limit surgical interventions. The objective of this study was to evaluate current literature on imaging techniques for the diagnosis of onychomatricoma in order to understand how this technology can help the presurgical diagnosis of this tumour. We searched in the Cochrane Skin Group Specialised library, Medline, Embase and LILACS databases all studies evaluating imaging technique for the diagnosis of onychomatricoma up to February 2018. We found that not only nail dermoscopy, but also reflectance confocal microscopy, optical coherence tomography, ultrasonography and magnetic resonance can be useful in this field.

“…Ultrasonography (US) is an imaging technique that uses reflected pulses of high‐frequency sound waves and can be used to assess soft tissues. Six onychomatricomas were evaluated by high‐resolution variable‐frequency US . In two cases, ultrasound imaging failed to provide diagnostic evidence of the disease .…”

“…The digitations into the nail plate appears with a Y-shape and with a high-intensity signal, probably due to a concentration of water higher than that surrounding nail, and axial images can show the holes in the nail plate and the tumoural digitations [3, 13, 15]. To the best of our knowledge, there are no other lesions reported in the literature, neither benign nor malignant, that have the same presentation as OM on MRI.…”

Onychomatricoma (OM) is a rare benign tumour of the nail matrix characterized by specific clinical and histologic features. The main clinical signs are thickening of the nail plate, xanthonychia, overcurvature of the nail plate, and multiple splinter haemorrhages. The diagnosis is based on clinical, radiological and histopathological findings. Histologically, the tumour is characterized by filiform epithelial projections. The objective of this study is to present the first reported Tunisian case of OM, focusing on the contribution of magnetic resonance imaging to the diagnosis of OM. A review on the subject is also presented.

Mohs micrographic surgery for nail unit tumours: an update and a critical review of the literature

Mohs micrographic surgery (MMS) is a good treatment option for epithelial neoplasms, especially when localized in areas where tissue conservation is crucial, such as the nail unit (NU). MMS is a method of radical excision offering high cure rates due to the margin control and functional preservation. Our aim is to provide a review on the use of MMS for the treatment of the most common nail tumours. We revised the current literature on the use of MMS to treat malignant neoplasms (Bowen's disease, squamous cell carcinoma, melanoma, basal cell carcinoma, keratoacanthoma, carcinoma cuniculatum) and benign neoplasms (onychomatricoma and glomus tumour). MMS represents a successful surgical option for nail tumours, firstly in terms of tissue conservation: the NU anatomy is complex and the preservation of the component structures is imperative for its functionality. Secondly, due to the surgical radicality, which is essential not only for the clearing of malignant tumours, but also for benign cases, in order to reduce recurrences. Although a conservative treatment of NU melanoma with MMS has been proposed, in our experience, the conservative approach with functional surgery is a good option for the treatment of non-invasive melanoma (in situ and Ia).
