Figure

  • Fig. 1 (A) Multiple linear scattered skin-colored patches with hypertrichosis on left upper back were observed. (B) Close-up view of left upper back. (C) Numerous smooth muscle bundles with various direction throughout dermis were shown (H&E, ×40). (D~F) In three sites, hypertrichosis with various density was shown on dermoscopy. (G~I) Different amount of smooth muscles according to hypertrichosis was observed in the reticular dermis (smooth muscle actin, ×20).

  • Fig. 2 Correlation between hypertrichosis and the amount of smooth muscle bundle.
