One of the most interesting cutaneous syndromes recently discussed in dermatologic literature is the condition described by Mucha,1 in 1916, and then by Habermann,2 in 1921, under the name of pityriasis lichenoides varioliformis acuta. Cases of the Mucha-Habermann syndrome are sufficiently rare to be recorded. Forty-three are reported in the literature. The number of actual cases must be much larger, but most of them are undoubtedly not recognized because the morphologic and clinical picture of the Mucha-Habermann syndrome is still unfamiliar to the rank and file of dermatologists and the medical profession.
What makes the cases of Mucha-Habermann syndrome still more interesting is the uncertainty of the nosologic classification and the sharp differences of opinion voiced in the literature in this regard.
For these reasons I am reporting a case and shall review the literature.
