ABSTRACT
Objective To analyze the disease constitution,accuracy of clinical and pathological diagnoses of skin biopsy samples in Peking Union Medical College Hospital.Methods A total of 29987 patients subjected to skin biopsy were collected from Department of Dermatology,Peking Union Medical College Hospital from June 2010 to November 2018,and clinical and histopathological diagnoses of these skin biopsy samples were analyzed retrospectively.Results According to the results of histopathological diagnosis,confirmed diagnoses of these patients could be classified into 33 categories and 242 kinds.Common disease categories included epidermal tumors (2931 cases,9.77％),connective tissue diseases (2809 cases,9.37％),melanocytic tumors (2078 cases,6.93％),erythematous scaly pustular dermatoses (1376 cases,4.59％),lichenoid dermatoses (1291cases,4.31％),allergic or eczematous skin diseases (1282 cases,4.28％)and infectious skin diseases (1156 cases,3.86％).Common skin diseases included scleroderma (1887 cases,6.29％),pigmented nevus (1755 cases,5.85％),seborrheic keratosis (1136 cases,3.79％),eczema (1089 cases,3.63％),psoriasis (881 cases,2.94％),lichen planus (867 cases,2.89％),lupus erythematosus (638 cases,2.13％),pemphigus (549 cases,1.83％),and basal cell carcinoma (501 cases,1.67％).Poor consistency was observed between clinical diagnosis and histopathological diagnosis of lichen planus,bullous pemphigoid,granuloma annulare and hypereosinophilic dermatitis.Conclusions Common disease categories of the skin biopsy samples in Peking Union Medical College Hospital were epidermal tumors,connective tissue diseases,melanocytic tumors,erythematous scaly pustular dermatoses,lichenoid dermatoses,and allergic or eczematous skin diseases.Poor consistency was observed between clinical and pathological diagnosis in some skin diseases,and understanding of these diseases should be improved.
ABSTRACT
HIV/syphilis co-infection is common because both conditions affect similar risk groups. HIV interferes with the natural history of syphilis, which often has atypical clinical features and nervous system involvement in the early stage of disease. We report the case of an HIV-positive patient with secondary syphilis, scaling palmoplantar keratoderma, scrotal eczema, balanitis and urethritis mimicking Reiter’s syndrome. Immunohistochemistry using polyclonal antibodies against Treponema pallidum revealed the presence of spirochetes, associated with the paretic form of parenchymal neurosyphilis. The patient was given crystalline penicillin, with complete resolution of dermatological and neurological symptoms, and no sequelae.

Background: We report a 35-year-old female patient with a one year history of a pustular and painful erythematous dermatitis, located in great folds, pubis and abdomen. She was evaluated in primary health care, receiving antifungal treatment, antimicrobials, topical and systemic non-steroidal anti-inflammatory drugs, with no response. A skin biopsy was compatible with subcorneal pustular dermatosis. She was initially treated with prednisone (0.8 mg/kg), observing a partial response. Therefore clotrimoxazole was initiated, obtaining an excellent response after 30 days of treatment.

Objective To investigate the characteristics of contact allergens in eczema and dermatitis for further diagnosis and treatment. Methods 340 cases with eczema and dermatitis were tested with a standardized screening antigen kit. Results (80. 88% ) of the 340 patients tested had at least one positive allergen among 18 of 20 standardized screening antigen. The first six allergens were nickel sulfate ( 29. 70% ), potassium dichroroate (27.64% ) ,fragrant mix(22.35% ) ,carba mix(20.29% ) ,thimerosal( 18. 82% ) ,benzocaine( 17.94% ). Conclusion Nickel sulfate,potassium dichromate,fragrance mix and carba mix were the main allergens causing dermatitis and eczema presently. Patch-testing was helpful in identifying the property of contact allergens in para eczema and dermatitis.
