Diffuse dermal angiomatosis associated with gestational gigantomastia

Gestational gigantomastia (GG) is a rare disorder of pregnancy, characterized by rapid, severe, painful enlargement of one or both breasts.1 While the etiology remains unclear, hormone receptor hypersensitivity, liver dysfunction, elevated prolactin, malignancy, and autoimmune conditions may contribute.1 We report a case of GG with concomitant diffuse dermal angiomatosis (DDA), characterized by dermal vascular proliferation in response to hypoxia.
