- Abstract
Dear Editor, Cutaneous mucinosis of infancy (CMI) is a clinical and pathologic subtype of localized lichen myxedematosus, also known as papular mucinosis.1 It is an idiopathic, benign entity with highly variable clinical features; only 14 cases have been published to date.2 We describe the main clinical and histologic features of two additional cases. The differential diagnosis should include scleromyxedema, self-healing cutaneous mucinosis (SHCM), and mucinous nevus (MN). As other entities such as Graves disease may also show abnormal mucin deposition,2 it is important to rule out thyroid disease.2,4 The clinical differential diagnosis should include connective tissue nevus, nevus lipomatosus, granuloma annulare, cutaneous myxoma, myofibroma, and lymphangioma.2 CMI lesions usually last for years, but there have been reports of spontaneous regression.4-5 As the condition is benign, it does not require treatment.
