A case of adult colloid milium with chronic sun exposure

A 57‐year‐old woman presented with a sudden onset of skin‐colored papules, mainly on the forehead ( Fig. 1 ), around the eyes, and on the dorsum of the hands ( Fig. 2 ). The papules had grown in number and size over 1 month. The papules were discrete, shiny, and dome‐shaped, varying in size between 1 and 5 mm. The patient was a farmer and had commonly been exposed to UV radiation in her work in the fields for a period of more than 45 years. She was fair‐skinned and admitted that she was reluctant to use sun protection during her outdoor work. No lesions were observed on the covered areas of the body. The diagnosis was uncertain and clinical differential diagnoses were those of primary cutaneous amyloidosis, senile sebaceous hyperplasia, adult colloid milium (ACM), and papular mucinosis.
