Changes in melanocytic nevi during pregnancy are frequently attributed to the new hormonal milieu and are dismissed without concern for malignancy. Recent studies suggest that pregnancy itself does not induce significant change in nevi, and delays in the assessment of changing moles may contribute to the often more advanced nature of melanomas diagnosed during or soon after pregnancy. Nevi on the breasts and abdomen can grow as a result of skin expansion, but studies have found no significant changes in nevi located in more stable areas such as the back or lower extremities. There is also insufficient evidence to support the notion that nevi darken during pregnancy. As such, any changing nevus that would raise concern for malignancy in a nonpregnant patient should do so in a pregnant patient as well. Pregnancy can, however, induce physiologic pigmentary changes that are often worrisome to both patients and physicians. These benign changes include melasma, pigmentary demarcation lines, secondary areola, and linea nigra as well as other less common findings. It is important for physicians to recognize these changes as physiologic to provide adequate reassurance to their patients and avoid unnecessary stress. [ABSTRACT FROM AUTHOR]

Actinic keratoses (AKs), especially on areas of the face, have a negative impact on a patient's quality of life (QoL). These lesions manifest on sun-damaged skin and have the potential to progress to squamous cell carcinoma. Field-directed therapy alone and in combination with lesion-directed treatment is effective in clearing both visible and nonvisible AK lesions. Topical treatments of AKs thus have the potential to improve a patient's well-being. However, evidence demonstrating improvements in patient QoL is limited, and is mostly based on observational or retrospective studies. Some prospective studies have reported unchanged or even worsening QoL despite excellent treatment outcomes. Our prospective, pilot study demonstrated a significant increase in QoL in 28 subjects with AKs of the face treated with ingenol mebutate gel 0.015%. QoL was assessed at days 0 and 60 using the Skindex-16 survey. Mean overall scores improved from 24.5% at baseline to 15.5% at day 60 (P=0.031). Improvements in QoL were consistent with an 80% reduction in AK lesion number at day 60. These improved QoL findings are in line with those from a recent retrospective study using ingenol mebutate 0.015% gel. This study therefore further demonstrates the potential for field therapy to improve both treatment outcomes and patient satisfaction. [ABSTRACT FROM AUTHOR]
