  • Porcine juvenile pustular psoriasiform dermatitis (PJPPD) is a disease of young pigs and characterized by nonpruritic round eruption of skin. The cause of this disease is yet undetermined but is presumed to be genetic predisposition. There may be few opportunities for veterinarian to detect this disease compared with actual situation in field because these lesions resolve spontaneously in two months. The authors detected spontaneous PJPPD case and performed clinical and pathological studies on three pigs from one farm. The specific skin lesions were observed in the forty-day old pigs of mixed breed, which were produced by the sows received semen from the same boar, restrictively. However, there was no skin lesion of pigs in suckling or fattening periods. Grossly, lesions were commonly found on the ventral abdominal part as a papule and were spreaded to the skin of whole body. With the spreading of lesions centrifugally, skin was showed as a umbilicated plaques or mosaic pattern with a few pustules or crusts. Microscopically, the most prominent lesion was the psoriasiform hyperplasia with acanthosis, down growth of rete ridges, exocytosis of eosinophils and neutrophils, ballooning degeneration of superficial epidermis, and koilocytic degeneration of keratinocytes. Additionally, there were moderate dermal edema and severe mixed cellular infiltration, especially eosinophils. No infectious agent which can cause the skin lesion, was detected or cultured, and no lesion caused by infectious agents was also observed, pathologically. With pathological results of this study, it is supposed that pathogenesis or severity of PJPPD may be related to the infiltration of eosinophil or hypersensitivity.

  • Clear cell acanthoma (CCA) is an asymptomatic benign lesion of unknown origin that typically appears as a brownish, dome-shaped papule on the leg. It has an unusual clinical feature in that it appears as chronic eczema, Bowen disease, or Paget disease on the areola. Its histopathologic findings are well-demarcated psoriasiform acanthosis with pale keratinocytes (clear cells) that are rich in intracellular glycogen, which stain positively with Periodic acid-Shiff. We report herein on a young female patient with CCA on the areolar areas.

  • Background: Tinea incognito is the dermatophytoses of atypical clinical appearance that is induced by topical and systemic steroid treatment or topical calcineurin inhibitor. Objective: The purpose of this study was to investigate the clinical and etiological aspects of tinea incognito. Methods: In the 10-year-period 2007-2017, we reviewed fifty-one patients with tinea incognito with regards to the age, gender, duration, and associated diseases. The patients with tinea incognito were further evaluated concerning the clinical manifestations and culture of organisms. Results: Age of the tinea incognito was most prevalent in the fifties (23.5%). The male-to-female ratio was 1:1.3. The most common type of infection was tinea corporis (52.9%), followed by tinea faciei (35.3%), tinea manus (5.9%), tinea barbae (3.5%), and tinea cruris (2.0%). The clinical features were to some extent diverse, ranging from eczema-like, seborrheic dermatitis-like, psoriasiform, folliculitis-like, rosacea-like, pyoderma-like, and purpura-like, and discoid lupus erythematosus-like. Trichophyton(T.) rubrum was the most common etiological agent (35.3%), followed by T. mentagrophytes (11.8%), Microsporum(M.) canis (7.8%), T. verrucosum (5.9%), T. erinacei, and M. gypseum (2.0%), respectively. Conclusion: Because of the increase in tinea incognito, there is a need for careful mycological examination in patients with tinea incognito.

A case of acquired acrodermatitis enteropathica with a normal serum zinc level but a low level in the hair (혈중 아연 농도는 정상이나 모발 검사에서는 감소된 아연 농도를 보인 일과성 장병성 선단 피부염 1례)

  • Acrodermatitis enteropathica (AE) is a rare autosomal recessive disorder of early infancy, and is characterized by periorificial dermatitis, alopecia, and intractable diarrhea. Serum zinc levels are usually low in untreated patients and the oral administration of zinc sulfate can clear skin lesions and other symptoms. Although premature and cow's milk-fed infants are at particular risk of developing AE, there have been a few reports about AE in term and breast-fed infants. We report a case of transient AE in a 4-month-old breast-fed infant. This patient suffered from diarrhea and dermatitis for more than a month. Her skin lesions were erythematous, scaly, crusted, psoriasiform, eczematous, with an eruption at the chin, and a periorificial disposition with involvement of the flexural areas of lower extremities. Her serum zinc level was almost normal at $129{\mu}g/dL$ (reference range: $60-121{\mu}g/dL$), but the zinc level in her hair was low: 8 mg percent (reference range: 10-21 mg percent). Skin biopsy findings were consistent with AE. Seven days after zinc supplementation, the skin lesions and diarrhea improved. The authors recommend that a clinical trial of zinc supplementation be considered in cases where there are suspicious of AE, even when the serum zinc level is normal.
