Naevus lipomatosus cutaneous superficialis (NLCS) of Hoffman-Zurhelle is a rare hamartomatous benign condition first described in 1921. Two clinical variants have been described: a classical form of multiple yellow papules that coalesce to form larger plaques with segmental distribution, and a solitary form also known as pedunculated lipofibroma. We present a case of early-stage NLCS with characteristic histopathological and dermoscopic features.

BACKGROUND: The 'rainbow pattern' was initially described as a highly specific dermoscopic feature of Kaposi sarcoma. Since then, it has been reported in many benign and malignant cutaneous tumours, including a few malignant melanomas (MMs). AIM: To determine the frequency and presentation of this dermoscopic pattern in primary cutaneous MMs in comparison to other cutaneous tumours. METHODS: The presence of a rainbow pattern was evaluated in a sample of 1100 dermoscopic images of different melanocytic and nonmelanocytic cutaneous neoplasms. RESULTS: The rainbow pattern was observed in 23 of 245 (9.4%) MM and 44 of 855 (5.1%) non-MM neoplasms. MMs presenting this feature were generally thicker: 82.6% > 1 mm and 43.0% > 2 mm. Compared with non-MMs, rainbow pattern in MMs was more commonly focal (82.7% vs. 36.4% nonfocal, P = 0.001) and associated with > 2 dermoscopic structures associated with MM (100% vs. 9% with fewer, P = 0.001). CONCLUSION: The rainbow pattern is a dermoscopic sign that can occasionally be observed in invasive MMs. In MMs, this feature is usually associated with other dermoscopic criteria of MM and located in a focal and eccentric area, as opposed to a diffuse and isolated presentation in non-MM neoplasms.

Introducción La enfermedad por coronavirus-19 (COVID-19) se ha relacionado con múltiples síntomas: respiratorios, trombóticos, neurológicos, digestivos o cutáneos. Estos últimos se han clasificado en 5 tipos: lesiones acroisquémicas, lesiones vesiculares, erupción urticarial, exantema maculopapular o lesiones livedoides. Sin embargo, se han descrito mucho menos las alteraciones orales asociadas a la COVID-19. Pacientes y métodos Presentamos un estudio transversal realizado durante abril del 2020 en el Hospital de Campaña de IFEMA examinando la mucosa oral de 666 pacientes con COVID-19. Resultados En total, 78 pacientes (11,7%) presentaron alteraciones en la mucosa oral. La más frecuente fue papilitis lingual transitoria anterior en forma de U (11,5%) asociada o no a edema lingual (6,6%); estomatitis aftosa (6,9%), mucositis (3,9%) glositis con depapilación en parches (3,9%), boca urente (5,3%), lengua saburral (1,6%) y enantema (0,5%). La mayoría refería disgeusia asociada. Conclusión La cavidad oral se puede alterar por la enfermedad COVID-19, el edema lingual con papilitis lingual transitoria en forma de U o la glositis con depapilación en parches son los signos encontrados con mayor frecuencia, al igual que la sensación de ardor en la cavidad oral o boca urente. Otras manifestaciones orales que se pueden asociar a la COVID-19 son mucositis con o sin aftas o el enantema. Todos pueden ser signos clave para un diagnóstico de esta enfermedad (AU)
Background Coronavirus disease 19 (COVID-19) has many manifestations, including respiratory, thrombotic, neurologic, digestive, and cutaneous ones. Cutaneous manifestations have been classified into 5 clinical patterns: acro-ischemic (pseudo-chilblain), vesicular, urticarial, maculopapular, and livedoid. Oral manifestations have also been reported, but much less frequently. Patients and methods We performed a cross-sectional study in which we examined the oral mucosa of 666 patients with COVID-19 at the IFEMA field hospital in Madrid in April 2020. Results Seventy-eight patients (11.7%) had changes involving the oral mucosa. The most common were transient anterior U-shaped lingual papillitis (11.5%) accompanied or not by tongue swelling (6.6%), aphthous stomatitis (6.9%), a burning sensation in the mouth (5.3%), mucositis (3.9%), glossitis with patchy depapillation (3.9%), white tongue (1.6%), and enanthema (0.5%). Most of the patients also reported taste disturbances. Conclusion COVID-19 also manifests in the oral cavity. The most common manifestations are transient U-shaped lingual papillitis, glossitis with patchy depapillation, and burning mouth syndrome. Mucositis with or without aphthous ulcers or enanthema may also be observed. Any these findings may be key clues to a diagnosis of COVID-19 (AU)
