(I) The author reports in this paper about the symptoms and diagnosis of a typical case of tuberculoidal macula. The patient is 28 years of age, japanese male.
Marked features of tuberculoid macula are following.
(1) a distinct thickening of local cutaneous nerves.
(2) a high degree of lymphocytosis in the blood.
(3) Mitsuda's reaction is strikingly positive.
(4) the lesions are quite similar histologically to tuberculoid.
(II) Both papules, which caused by Mitsuda's reaction in two lepers, are seen in a case of tuberculoidal macula and in an other nervous case, and they are quite similar to tuberculoidal macula from the histological standpoint.
(III) Dr. Mitsuda and the members of his school believe that the tuberculoidal macula is a reaction caused by lepra bacillus. The positive skin test in a patient shows the existence of a bodily resistence against lepra bacillus and the prognosis is better than a case of the negative skin test.
