Cutaneous mucinoses encompass a variety of cutaneous disorders. Cutaneous focal mucinosis ( CFM ) was originally described as an asymptomatic solitary lesion characterized by abundant focal cutaneous mucin deposits. However, multiple focal mucinous lesions associated with systemic diseases have also been designated as CFM . Our clinicopathological study of 11 cases of solitary lesions confirmed that CFM is a unique primary cutaneous mucinosis unrelated to mucinosis‐associated systemic diseases. We suggest calling this group of CFM lesions “solitary CFM ” to distinguish them from multiple CFM associated with mucinosis associated systemic diseases. Our cases showed slight male predominance with a median age of 50 years. They occurred most often on the extremities (45%), presented as asymptomatic solitary, white to erythematous, small, soft, fibroma‐like lesions. None of the clinical impressions were of CFM . We call attention to include solitary CFM in clinical differential diagnosis of polypoid skin lesions.
