Eosinophilic pustular folliculitis (EPF) is a sterile inflammatory dermatosis of unknown etiology. In addition to classic EPF, which affects otherwise healthy individuals, an immunocompromised state can cause immunosuppression-associated EPF (IS-EPF), which may be referred to dermatologists in inpatient services for assessments. Infancy-associated EPF (I-EPF) is the least characterized subtype, being observed mainly in non-Japanese infants.

Eosinophilic pustular folliculitis (EPF) is a non-infectious inflammatory dermatosis of unknown etiology that principally affects the hair follicles. There are three variants of EPF: (i) classic EPF; (ii) immunosuppression-associated EPF, which is subdivided into HIV-associated (IS/HIV) and non-HIV-associated (IS/non-HIV); and (iii) infancy-associated EPF. Oral indomethacin is efficacious, especially for classic EPF.

Eosinophilic pustular folliculitis (EPF) is characterized by a non-infectious infiltration of eosinophils in the hair follicles. It has three variants: (i) classic EPF; (ii) immunosuppression-associated EPF, which herein is subdivided into HIV-associated (IS/HIV) and non-HIV-associated (IS/non-HIV); and (iii) infancy-associated EPF (I-EPF). The rarity of EPF has hindered our understanding of this entity.

Eosinophilic pustular folliculitis (EPF), also known as Ofuji's disease, is an inflammatory dermatosis that was first described in Japan in 1970. More than 300 cases have been reported so far, and 113 Japanese cases have been reported in Japan since 1980. To comprehend the characteristics of Japanese EPF cases, we classified these cases into three types: classic, immunosuppression-associated (IS-EPF), and infancy-associated (I-EPF).

Pyoderma gangrenosum (PG) is a rare, immune-mediated ulcerating skin disease. In up to 50 percent of the cases, PG is associated with underlying systemic disorders, most commonly inflammatory bowel diseases, connective tissue diseases, or hematological disorders. Herein, we present a case of refractory PG associated with ulcerative colitis (UC), successfully treated with infliximab.

We reviewed the causes of "loss of skin color" in 144 patients, who visited Vitiligo Clinic of Kyoto University Hospital between April 2005 and August 2008. The numbers of patients with generalized and segmental Vitiligo vulgaris were 98 (68.1%) and 26 (18.

Background: Clinical studies of the use of allogeneic cultured dermal substitutes (CDSs) have been conducted in 30 medical centers across Japan with the support of the Millennium Project of the Ministry of Health, Labor and Welfare. The CDS is prepared by plating cultured fibroblasts on a spongy matrix made from hyaluronic acid and atelo-collagen. The aim of the present clinical study was to evaluate an allogeneic CDS as cell therapy in which cytokines are released to promote wound healing.

Chemotherapy-induced acral erythema (CIAE) is a rare cutaneous reaction to high-dose chemotherapy, clinically featuring painful erythema on the palms and soles. Docetaxel (Taxotere), an anticancer agent, is known to cause various reactions, including CIAE. We experienced a case of docetaxel-induced acral erythema with facial edematous erythema that coincidentally emerged and regressed with appearance and disappearance of the acral lesions.
