From November 1961 to may 1967 fifteen cases of sporotrichosis were observed and studied in laborers who worked in a Pottery Industry localized near Curitiba. Thirteen of these patients presented the disease under special characteristics which led us to consider it being a different and- until now undistinguished clinical form of sporotrichosis. The main characteristics observed were as follows: 1 - generally few superficial and small skin lesions of different ages and stages of growth and involution, together with scars of lesions already self-healed; 2 - apperance of the diesease owing to repeated and intermittent inoculations of the causal microorganism - Spororicum Schenkii - possibly existing pottery packing straw and which introduces itself into the skin through the unclothed and traumatized regions of the body, where the lesions were present: 3 final and natural cure of the disease after an average space of time of two years, even if the individuals remain in the working environment, subject to sources of infection. It was not possible to isolate the causal microorganism from the straw (thoght to be the reservoir of Spororichum) used to package the pottery, even after 600 attempts to obtain cultures. But in this pottery industry only straw manipulators had the disease. The analysis of the Table shows us the details of the cases studied. In this manner only two patients presented deep lesions as most frequently seen in sporotrichosis. In all the other cases the skin lesions were small, superficial, either verrucous and impetiginous or papular, furuncular and tubercular, some of them almost healed without any treatment. Small scars were present in the majority of the patients, on the unclothed regions as well, recalling sometimes sequelae of small-pox or variola. Almost all individuals received iodic treatment after first clinical examinations, which certainly accelerated the cure. But the presense of selfhealed lesions before the treatment and the two cases finally cured without any medication show us the self-healing - and perhaps vaccinating - character of this sporotrichosis form, now described.
