To the Editor.—  A Japanese farmer had a lesion on the elbow, which clinically was considered neoplastic by the referring physician. No bacteriologic studies were made prior to receiving the formalin-fixed specimen. The changes in the skin were typical of chromoblastomycosis.

Report of a Case 

Clinical History.—  A Japanese man, age 58 years, had been a farmer for many years, and recently had worked as a grocery storekeeper. He first noticed a small eruption over the left elbow joint during the past four to five years. Since then it had enlarged. Examination disclosed a scar-like, partially crusted elevation of the skin over the left elbow joint which measured 3.0 × 2.0 cm. A total excision was done and the specimen was sent to The ABCC Pathology Department in Nagasaki.

Pathology Findings.—  The specimen was received in formalin and consisted of an irregular flat piece of tissue, measuring 3.8 × 2.2 × 0.3 cm. The surface was coarsely granular.
