Figure 1 Clinical presentation of Type V ACC. (A) Anterolateral view of trunk showing extensive bilateral, symmetrical skin defects on the lateral trunk and proximal lower extremities. Note the triangular morphology with apices pointing medially toward the umbilicus, consistent with vascular watershed distribution. The underlying muscle fascia is visible, covered by a thin translucent membrane. (B) Posterior view demonstrating extension of truncal lesions posteriorly along the lateral trunk. Lesions measure approximately 8×10 cm (right) and 7×9 cm (left). (C) Close-up view of right lateral trunk lesion showing well-demarcated borders with erythematous rim (2–3 mm width) and exposed underlying tissue without active bleeding. (D) Post-treatment view at day 14 showing the application of a human epidermal allograft (Epifast™) covered with a hydrocolloid dressing (DuoDERM®). Early granulation tissue formation is visible at lesion margins. ACC – aplasia cutis congenita.
