Case for Diagnosis: Swimming-Pool Granuloma with Many Eosinophils. Presented by Dr. Walter F. Schwartz.
An 8-year-old white boy, presents only one lesion which is on the tip of the chin. This began as a small, slightly red nodule three and a half months ago and has increased steadily in size since; in fact, it has doubled in size since first seen by us five weeks ago. At that time, the small nodule was located at the end of an old traumatic scar (now obscured by the tumor). The parents cannot recall how or when the scar was produced.
Examination discloses 2.5 cm. firm, somewhat flattened, dusky red, painless mass, apparently involving the upper portions of the corium and situated on the tip of the chin. It is freely movable and not attached to deeper structures. Lymph nodes are not palpable. The boy, otherwise, is in apparent good health.
