スポロトリクム症—本州日本海岸地方における第1例

SPOROTRICHOSIS:THE FIRST CASE IN HONSHU (THE MAIN LAND OF JAPAN) FACING SEA OF JAPAN

I．はじめに

　スポロトリクム症は本邦においては，関東^1），九州地方^2）に多く，山陽^3），近畿地方からもしばしば報告されており，近年になつて，北海道^4），東北^5）6），四国地方^7）からも数例の報告をみているが，山陰，北陸および東北地方の日本海側からの本症の確実な報告は未だみられない。最近われわれは新潟県内で罹患したと思われる本症の1例を経験したのでここに報告する。

A 72-year-old dealer in coals, living in Shibata City of Niigata Prefecture, had a slightly elevated, erythematous, thumb-tip-sized infiltrated eruption on the nasal root, which developed into ulceration in some part. The similar lesion appeared on the right check subsequently.

Histologic specimen showed granulomatous infiltration throughout the dermis. In the upper dermis circumscribed cell proliferations (Kitamura) or sporotrichotic granulomas (Lurie) were recognized, in which asteroid bodies were demonstrated.

Sporotrichum schenckii was isolated. Lymphangitis and granulomas were found in mesen-teria of mice which were inoculated this fungus.

Sporotrichin reaction was positive and the patient's serum proved high agglutinin titer.
