A case of multiple soft fibromas complicated with pityriasis versicolor during pregnancy: A case report

Abstract

Dermatological conditions in pregnancy pose unique challenges due to concerns for maternal and fetal health. We present a case of a 32-year-old primigravida who, at 36 weeks of gestation, exhibited melanotic papules and neoplasms on her neck, chest, and breasts. Seeking evaluation for potential effects on her unborn child and breastfeeding, she presented to our dermatological outpatient facility. Physical examination revealed varied pigmented papules and verrucous proliferations. Laboratory tests and imaging were unremarkable, with histological analysis confirming fibromas and pityriasis versicolor. The patient declined treatment during pregnancy, and postpartum, spontaneous regression of lesions occurred, with complete resolution within 1 year. The child exhibited normal development, with no recurrence observed at the 2-year follow-up. This case underscores the importance of multidisciplinary care and long-term monitoring in managing dermatological manifestations during pregnancy.
