Adult colloid milium is clinically distinguishable from its histopathologic mimic cutaneous amyloidosis.

Colloid milium, also known as colloid degeneration of the skin or dermal hyalinosis, is a cutaneous deposition disease that presents as three subtypes: juvenile, nodular, and adult. Adult colloid milium is characterized by amyloid-like depositions in the dermis, mimicking cutaneous amyloidosis histologically. A 70-year-old man presented with lesions on the sun-exposed skin of the face, dorsal hands, and dorsal forearms resembling adult colloid milium. A punch biopsy was performed on the left zygoma and histopathological features were consistent with this diagnosis, though cutaneous amyloidosis was considered. A case of adult colloid milium is presented to emphasize the clinical and histopathologic differentiation from cutaneous amyloidosis.

A cross-sectional survey of prevalence and correlates of sunscreen use among a rural Tri-State Appalachian population.

Over five million people are diagnosed with skin cancers each year. With the sun's ultraviolet radiation exposure being the major risk factor for all skin cancers, sunscreen use is a vital preventative measure. However, in the US, sunscreen use remains inadequate. Furthermore, research regarding sunscreen use amongst rural populations has been particularly sparse. To identify the prevalence of sunscreen use and identify correlates thereof, a cross-sectional study was conducted on a sample of patients from rural Tri-State Appalachia. A total of 212 patients participated in this study. Findings showed that young individuals, females and those with higher educational attainment were more likely to utilize sunscreen. Furthermore, individuals with skin types prone to burning were four times as likely to utilize sunscreen. Overall, sunscreen use amongst residents in the Tri-State area was low, emphasizing the need for targeted interventions to prevent the incidence of skin cancer amongst this population.
