Meshed skin grafting is a common technique in operations to minimize surgery on the donor site area. However, the donor site area is empirically determined by surgeons due to the lack of a reliable formula to calculate the donor area required to cover a skin defect. To determine the minimal size for donor skin, the expansion rates of 1.5:1, 3:1, and 6:1 meshed skin graft and the area actually covered by them were investigated in real-world operations. About 51 patients who received 57 operations with meshed skin grafts were enrolled in this study. The average clinical coverage rates of area in cases in which 1.5:1, 3:1, or 6:1 meshed skin grafting was performed were 1.02, 1.29, or 2.18, respectively. Those rates were notably low when recipient sites were concave. The average expansion rates of 1.5:1, 3:1, and 6:1 meshed skin grafts were about 1.16, 1.61, and 2.32, respectively. These results indicate that the size of donor skin should be about 85%, 60%, and 45% size of the recipient site to achieve the target 1.5:1, 3:1, and 6:1 meshed skin graft, respectively. In addition, the donor area should be adjusted in consideration of the shape of the recipient sites.

Grover's disease (GD) is a self-limiting skin disorder characterized by multiple pruritic papules or vesicles on the trunk and extremities. 1 Histologically, it shows focal acanthosis and dyskeratosis in the epidermis. 1 Topical corticosteroids are useful in a limited number of patients. 2 In addition, the efficacy of vitamin D analog, calcipotriol ointment, was reported in a few cases. 3,4 Here, we report a case of GD, successfully treated with a calcipotriene/betamethasone dipropionate (Cal/BD) ointment, although neither the use of topical corti
