“…The physiology of hyperpigmentation and chloasma may be related to elevated serum levels of melanocyte-stimulating hormone, estrogen and possibly progesterone [8]. Mild generalized hyperpigmentation is usually seen with accentuation of normally hyperpigmented areas such as the areola, nipples, genital skin, axillae and inner thighs [9]. Objectives of our study was to evaluate the trimester wise cutaneous changes during pregnancy.…”

Objectives: This present study was to evaluate the various dermatological manifestation during pregnancy. Methods: A detailed history including chief complaints related to skin, onset in relation to duration of pregnancy, complete general physical & systemic examinations, associated skin / medical disorders were performed to all patients. Investigations-CBC, OGTT, TSH, VDRL, HIV, HBsAg, Anti-HCV, Urine routine examination, LFT, S. Bile Acids, KOH mount, Skin biopsy and DIF were done wherever required. Results: A total of 200 pregnant women were included in this study. The mean age of participants was 23.43±4.12 years. Majority of women 104(52%) were seen in third trimester. 62(31%) women were in second trimester. and 34(17%) were in the first trimester of pregnancy. Most of the women 136(68%) were multigravida and 64(32%) were primigravida. Areola/nipple180(90%) was the most common pigmentary changes. Pedal oedema 26(13%) was the most common type of vascular changes seen in third trimester pregnant women. Most common type of connective tissue changes was Striae gravidarum 113(56.5%). Conclusions: Cutaneous manifestations are very common during pregnancy. Areola/nipple (pigmentary changes), malar (type of chloasma), pedal oedema (vascular changes) and striae gravidarum (connective tissue changes) are common cutaneous changes are seen during pregnancy.

Linea nigra is a distinctive presentation of asymptomatic cutaneous hyperpigmentation on the abdomen that usually extends from the umbilicus to the pubic symphysis. It is frequently observed as a physiologic change associated with pregnancy. A primigravida 19-year-old woman began to develop skin darkening during week 24 of gestation. She delivered a healthy infant. Three months postpartum, the hyperpigmentation had not resolved. After the benign characteristics of her cutaneous hyperpigmentation were explained, the patient decided to clinically monitor the dark linear streak. Similar to this patient, clinical studies of pregnant women have observed the incidence of pregnancy-associated linea nigra to range from 32% to 92%; in contrast to this woman, partial or complete spontaneous resolution of the skin darkening commonly occurs after delivery of the newborn. During gestation, the development of linea nigra has been postulated to be caused by elevated estrogen, progesterone, and/or melanocyte-stimulating hormone levels. Linea nigra is not restricted to gestational females; it has also been noted in newborns and children. In addition, it has also been observed in men who had either benign prostate hyperplasia or prostate cancer. In summary, linea nigra is often an acquired longitudinal streak of benign cutaneous hyperpigmentation on the abdomen; when linea nigra is pregnancy-associated, the skin darkening often partially or completely resolves, spontaneously after delivery.
