  "account": "Shannon Smith, 27, and Ayrton Hall, 29, were surprised to learn their newborn son Reuben had a purple mark on his left arm, given he was born via C-section. The parents wondered if the mark was caused by the surgery. When Reuben was four weeks old, the purple mark became bright red but remained flat against his skin. Concerned, Shannon and Ayrton sought advice from a midwife, who suggested they might have bruised Reuben due to medication use. A pediatrician later confirmed the mark was a port wine stain birthmark, leading to a referral for further evaluation by a dermatologist.\n\nPort wine stains are vascular birthmarks caused by abnormal blood vessels beneath the skin, appearing flat and red or purple at birth. Shannon and Ayrton observed the mark's changing color and texture, which initially alarmed them. Dr. Matthew R. Greives, MD, MS, FACS, chair of plastic surgery at UT Health and director of the vascular anomalies team at Memorial Hermann Health System, advised that babies with port wine stains should be evaluated and monitored by a vascular anomalies team. These benign lesions can thicken and become bumpy over time if untreated. Treatment typically involves laser treatments to lighten the birthmark and prevent worsening, with multiple sessions required and potential maintenance treatments as the child grows.\n\nThe condition may have genetic causes, leading to abnormal blood vessel growth in affected tissue and, in rare cases, limb overgrowth. Dr. Greives recommends starting treatment at a young age for optimal results, suggesting an initial series of laser treatments and annual evaluations. Now 10 weeks old, Reuben's birthmark has a cobblestone appearance, with some red patches fading as he grows. In a TikTok post, Shannon calls the mark Reuben's \"iron fist,\" emphasizing the family's desire for him to embrace and be proud of his uniqueness.",
