title: [A case of trichophytia profunda acuta of the glabrous skin].
abstract: We report the case of a 68-year-old man with eruption on his left arm in the lesion where he wore his wrist watch. He was treated with topical steroid ointment at another clinic. He also suffered from tinea pedis. Examination of the scale and hair showed hyphal elements. Histopathological examination revealed granulomatous reaction around the hair follicles. We found no fungal elements in the tissue in spite of detecting serial sections of them. Trichophyton rubrum was cultured from tissue and scale, and the case was diagnosed as Trichophytia profunda acuta of the glabrous skin. Spontaneous remission was shown only by topical treatment for tinea pedis. A therapy of "wait and see" may be one choice.
