A Case of Disseminated Cutaneous Sporotrichosis Mimicking Sarcoidosis, that Required Four Biopsies to Diagnose.

A 69-year-old Japanese woman visited Tokai University Oiso hospital with cutaneous ulcers on her left upper arm that appeared in January 2013, and on her right nose that appeared in December of 2013. Neither the two biopsies and tissue culture from the arm lesion nor the biopsy and tissue culture from the nose lesion detected any organism. In December of 2013, she was diagnosed as cutaneous sarcoidosis at Oiso hospital and treated with oral prednisolone for six months, however, did not show improvement.

Two Atypical Cases of Tick Bites: A Fully Engorged Tick and Multiple Ticks.

Ticks have a cosmopolitan distribution and, as such, are also found in Japan. Ticks are typically ectoparasites of wild animals, however, humans can also be bitten when visiting environments inhabited by ticks. Herein, we describe two cases with atypical tick bites.

Successful Endoscopic Resection in a Case of Ectopic and Metachronous Quintuple Gastric Cancers.

A 71-year-old man was referred to us from another hospital for endoscopic treatment of a IIc lesion at the anterior wall of the lower body of the stomach. In November 2008, he underwent resection of this lesion with endoscopic submucosal dissection (ESD). Follow-up endoscopy revealed a IIc lesion in the posterior wall of the lower body of the stomach, and ESD was again performed in February 2009.

Case of disseminated vesicles of herpes zoster developing one day before the onset of local eruption in a hospitalized immunocompromised patient.

Disseminated herpes zoster is not rare in immunocompromised patient. It is defined as at least 20 lesions in multiple dermatomes that occur within a week of the onset of local eruption. Herein, we report that a case of disseminated vesicles of herpes zoster (HZ) that developed one day before the onset of local eruption in an immunocompromised patient.

Diagnostic usefulness of findings in Doppler sonography for amelanotic melanoma.

To evaluate the diagnostic usefulness of Doppler sonography for amelanotic melanoma (AM), the correspondence between the findings of dermoscopy and Doppler sonography was investigated in AM in comparison with other hypopigmented tumors. Seven cases with AM and 11 cases with squamous cell carcinoma (SCC), 10 cases with non- or hypopigmented basal cell carcinoma (NP-BCC) and six cases with eccrine poroma (EP) as hypopigmented tumors were investigated. EP is readily recognized by differences from AM and SCC based on a single vertical and non-torvtuous vessels.

A case of chromomycosis treated by surgical therapy combined with preceded oral administration of terbinafine to reduce the size of the lesion.

Chromomycosis is a chronic fungal disease of the skin and subcutaneous tissues caused by a group of dematiaceous black fungi. Small lesions can be removed with excision, but other cases are difficult to treat. We report a case of chromomycosis caused by Fonsecaea pedrosoi (F.

A novel splicing variant of CADM2 as a protective transcript of psoriasis.

CADM2, a candidate gene for psoriasis, was identified by a genome-wide association study using microsatellites in the Japanese population (561 cases and 561 controls). Moreover, haplotype analysis included an additional 68 SNPs and indicated that a 110-kb haplotype block was detected for the protective risk haplotype of psoriasis. We also identified an initial exon of novel splicing variants in this haplotype block.

Multiple Bowen's disease in a patient with a history of possible arsenic exposure: a case report.

A 81-year-old man with a patch of scaly erythema on his scrotum visited Hiratsuka Kyosai Hospital in June 2006. Reddish, scaly plaques, which were untreated, were present on his back and lower legs since 1999. Pathological examination of the lesions on the scrotum revealed Bowen's disease; therefore he was referred to our clinic for further treatment.

A novel case of nocardiosis with skin lesion due to Nocardia araoensis.

Nocardiosis is caused by gram-positive aerobic actinomycetes that live in soil and are known to be responsible for opportunistic infections. The condition mostly affects the lung, brain or skin. Here, we present a 24-year-old Japanese woman who had had systemic lupus erythematosus since the age of 20 years, and lupus nephritis since the age of 23 years.

Protein oxidative damage and heme oxygenase in sunlight-exposed human skin: roles of MAPK responses to oxidative stress.

Oxidative stress derived from ultraviolet (UV) light in sunlight induces different hazardous effects in the skin, including sunburn, photo-aging and DNA mutagenesis. In this study, the protein-bound lipid peroxidation products 4-hydroxy-2-nonenal (HNE) and the oxidative DNA damage marker 8-hydroxy-2'-deoxyguanosine (8OHdG) were investigated in chronically sun-exposed and sun-protected human skins using immunohistochemistry. The levels of antioxidative enzymes, such as heme oxygenase 1 and 2, Cu/Zn-SOD, Mn-SOD and catalase, were also examined.

Lentigo maligna occurring in a patient with the past history of laser therapy.

A 70-year-old Japanese woman visited our clinic with a pigmented patch on her face from her upper lip to under her nose following laser therapy 15 years ago. Physical examination revealed an asymmetrical dark brown macule with a clear border along with irregular black dots measuring 20 mm. A biopsy specimen showed some irregular-sized atypical melanocytes with deep-colored nuclei on staining.

The incidence of internal malignancies in autoimmune bullous diseases.

Autoimmune bullous diseases are classified into pemphigus and pemphigoid. Pemphigus is designated as incurable disease by the Ministry of Health, Labor and Welfare, and it is said that pemphigus is difficult to care and can be fatal. The clinical course of bullous pemphigoid (BP) is better than that of pemphigus.
