Multiple minute digitate hyperkeratosis
Multiple, 2-3 mm, honey-colored, crateriform papules distributed over the right mammary region. These lesions were present bilaterally on the anterior thoracic wall

Multiple minute digitate hyperkeratosis (also known as "Digitate keratoses," "Disseminated spiked hyperkeratosis," "Familial disseminated piliform hyperkeratosis," and "Minute aggregate keratosis") is a rare cutaneous condition, with about half of cases being familial, inherited in an autosomal dominant fashion, while the other half are sporadic.[1]

This disease has a unique histology, so a biopsy and further tests should be done to confirm the diagnosis and rule out other disorders and malignancy.[2]
