Eosinophilic granuloma of soft tissue: a case report and literature review

Solitary Hepatic Eosinophilic Granuloma Accompanied by Eosinophilia Without Parasitosis: Report of a Case

A 43-year-old Japanese woman visited for a hepatic tumor incidentally found. We suspected eosinophilic granuloma of the liver (EGL) due to visceral larva migrans (VLM). However, neither past history nor medical interview indicated a risk of parasitosis. Blood testing revealed eosinophilia, serum examination showed normal results for immunoglobulin E, and enzyme-linked immunosorbent assay yielded negative for Toxocara and Anisakis. Gastric and colonic endoscopy revealed normal features. Several imagings showed central necrosis of the tumor. After informed consent, laparoscopic resection was performed. Histopathological examination showed EGL without parasites. No recurrence had occurred postoperatively. Most reports documented that EGL are caused by VLM. However, parasites are not always demonstrable on serum, histopathological, or immunochemical examinations. When acting as allergens to induce type I responses, microscopic agents other than parasites in the intestinal tract could induce eosinophilic inflammation in the liver. Accumulation of more cases should help clarify other pathogeneses for EGL.

New treatment modalities for granuloma faciale

Granuloma faciale (GF) is a rare, chronic skin disorder in which numerous treatment modalities have been used without any consistent long-term effect. We report three cases of GF, two of which were successfully treated with the Laserscope potassium-titanyl-phosphate 532-nm laser within 2 weeks and one with topical tacrolimus ointment 0.1%. Our observations suggest that these new treatment modalities for GF, which we report here for the first time, can provide effective and non-invasive treatment for this disease.
