Histopathology revealed fascicular proliferations of bland spindle cells in the superficial dermis. Immunohistochemically, the lesions were weakly positive for smooth muscle actin and negative for CD68, CD34, desmin and S100 protein, with loss of elastic fibres. No relevant germline driver mutations were detected in peripheral blood DNA. Spontaneous regression occurred in five patients during follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>We propose the term \u2018disseminated myofibroblastic papulosis\u2019 for this newly recognized, probably underdiagnosed entity.
