Adult Kerion Celsi Caused by Trichophyton tonsurans Secondary to Black Dot Tinea Capitis.

A 34-year-old female patient presented with hair loss due to black dot tinea capitis caused by Trichophyton tonsurans for 6 months. Hair loss progressed to painful swelling for 2 months due to kerion Celsi which may be associated with treatment like topical minoxidil, antibiotic and corticosteroid previously. The patient was treated with oral Itraconazole initially without success but cured by Terbinafine eventually.

Netherton syndrome in one Chinese adult with a novel mutation in the SPINK5 gene and immunohistochemical studies of LEKTI.

Background: Netherton syndrome (NS) is a severe autosomal recessive ichthyosis. It is characterized by congenital ichthyosiform erythroderma, trichorrhexis invaginata, ichthyosis linearis circumflexa, atopic diathesis, and frequent bacterial infections. The disease is caused by mutations in the SPINK5 (serine protease inhibitor Kazal-type 5) gene, a new type of serine protease inhibitor involved in the regulation of skin barrier formation and immunity.

[Expression, clinical and pathological significance of KIAA1173 gene in skin squamous cell carcinoma].

Objective: To clone, prepare probe for and explore the expression levels of KIAA1173 gene in skin squamous cell carcinoma (SSCC) and investigate its expression, clinical and pathological significance.

Methods: KIAA1173 gene fragment (354 bp) was cloned and its cDNA probe prepared. The expression of KIAA1173 gene in 133 SSCC tissue samples (including 52 specimens of I, 37 specimens of II, 31 specimens of III and 13 specimens of IV) and 47 normal controls were examined by in situ hybridization (ISH).
