RESUMO
BACKGROUND: Pigmentary demarcation lines (PDL) are physiological abrupt transition lines between hyperpigmented skin and lighter areas. Recent evidence suggests that they involve the face. AIMS: To survey facial PDL in Saudi females referred to general dermatology clinics for various complaints and determine any associated risks. METHODS: Screening for facial lines was done in general dermatology clinics over a year. Whenever a patient was found to have facial PDL, a detailed questionnaire and examination were undertaken. RESULTS: Out of 1033 patients screened, 144 patients (14%) were found to have at least one of the facial PDLs. The median age of onset was 16 years. The most common line was F with 76 patients (53%). Family history was positive in 51 patients (35%). CONCLUSION: Facial PDL is a common and chronic pigmentary problem in Saudi women. It should be recognized and differentiated from other similar diseases like melasma. A significant proportion of patients have a milder presentation.

BACKGROUND: During pregnancy profound immunologic, metabolic, endocrine and vascular changes occur, that are responsible for the changes of the skin and its appendages, both physiologic and pathologic. AIMS: We undertook a clinical study to find out the frequency and pattern of skin changes in pregnant women. METHODS: All consecutive pregnant women were included in the study. RESULTS: A total of 607 pregnant women were included in this study. Of these, 303 (49.9%) pregnant women were primigravida and 304 (51.1%) were multigravida. Skin changes grouped into: physiological changes (all cases), specific dermatoses (22 cases) and other dermatoses affected by pregnancy (125 cases). Most common physiological changes were pigmentary alterations seen in 555 (91.4%) followed by striae seen in 484 (79.7%) cases. Of the various specific dermatoses of pregnancy, pruritic urticarial papules and plaques of pregnancy (PUPPP) was the most common disorder (14 cases) followed by pruritus gravidarum (5 cases). The most common dermatoses affected by pregnancy were candidal vaginitis (17 cases), acne vulgaris (15 cases), skin tags (15 cases), eczemas (14 cases). CONCLUSION: This study brings into focus various skin changes during pregnancy in south India.
