Professor Jin Hongzhong: Specialist in Autoimmune and Severe Skin Disease
Professor Jin Hongzhong is Director of Dermatology at Peking Union Medical College Hospital (PUMCH), a chief physician, professor, and doctoral supervisor. His clinical work focuses on immune-mediated, inflammatory, blistering, vascular, and pigmentary skin disorders.
He has particular experience with cutaneous lupus, dermatomyositis, pemphigus and other blistering diseases, vasculitis, psoriasis, vascular lesions, and selected laser treatments for pigmentary conditions.
International patients can learn more about the hospital’s specialties, medical-record requirements, and appointment planning in our Peking Union Medical College Hospital international patient guide.
Clinical Specialties
Professor Jin’s principal areas include:
- cutaneous lupus erythematosus;
- dermatomyositis and inflammatory muscle disease with skin findings;
- pemphigus and other autoimmune blistering diseases;
- cutaneous vasculitis;
- psoriasis, including severe or difficult forms;
- immune-related and systemic skin disease;
- vascular lesions and selected birthmarks;
- laser treatment for selected pigmentary conditions; and
- complex cases requiring dermatology, rheumatology, pathology, or other specialist input.
Dermatomyositis
Dermatomyositis is an autoimmune disease that can affect the skin, muscles, lungs, swallowing function, and other organs. Skin signs may include a violet rash around the eyelids, scaly areas over the knuckles, sun-sensitive redness, scalp inflammation, or painful ulcers.
Muscle weakness may make it difficult to climb stairs, rise from a chair, lift the arms, or swallow. Some patients have significant skin or lung disease without obvious muscle weakness.
Professor Jin has contributed to Chinese expert guidance on the diagnosis and treatment of adult dermatomyositis. Evaluation may involve skin examination, muscle enzymes, autoimmune antibodies, electromyography, MRI, lung imaging, pulmonary-function testing, and biopsy.
Because dermatomyositis can be associated with interstitial lung disease and, in some patients, malignancy, screening should be individualized according to age, symptoms, antibody pattern, and other risk factors.
Pemphigus and Autoimmune Blistering Disease
Pemphigus is a group of autoimmune disorders that cause fragile blisters and painful erosions of the skin or mucous membranes. Without appropriate treatment, extensive disease can lead to infection, fluid loss, difficulty eating, and other serious complications.
Professor Jin has led or participated in Chinese clinical guidance for pemphigus and paraneoplastic pemphigus. Diagnosis usually requires a combination of clinical examination, skin biopsy, direct immunofluorescence, and blood antibody testing.
Treatment may include corticosteroids, steroid-sparing immunosuppressive medicines, biologic therapy, wound care, infection prevention, and nutritional support. Paraneoplastic pemphigus requires investigation for an associated tumor or hematologic disease.
Cutaneous Lupus and Vasculitis
Lupus can affect the skin alone or occur as part of systemic lupus erythematosus. Sun-sensitive rashes, scarring lesions, hair loss, mouth ulcers, vascular changes, and other findings may provide clues to systemic disease.
Cutaneous vasculitis results from inflammation of blood vessels in the skin and may cause purple spots, ulcers, painful nodules, blisters, or tissue damage. The cause may be autoimmune disease, infection, medicine exposure, malignancy, or another condition.
A dermatologist may coordinate testing with rheumatology, nephrology, hematology, or other departments when symptoms suggest internal-organ involvement.
Psoriasis
Psoriasis is a chronic immune-mediated disease that can affect the skin, scalp, nails, and joints. Severe forms may involve most of the skin or produce pustules and systemic illness.
Professor Jin’s research includes proteomic investigation of erythrodermic psoriasis, a serious form associated with widespread redness and scaling. Treatment options may include topical therapy, phototherapy, conventional systemic medicines, or biologic treatment.
Medication selection depends on disease severity, joint symptoms, infection risk, pregnancy plans, liver and kidney health, previous treatment, and access to monitoring.
Vascular and Pigmentary Skin Conditions
Professor Jin also treats selected vascular lesions and pigmentary conditions using laser and other dermatologic techniques. These may include vascular birthmarks, nevus of Ota, and related conditions.
Laser suitability depends on diagnosis, skin type, lesion depth, location, previous treatment, and risk of scarring or pigment change. Multiple treatment sessions may be required, and results vary.
Research and Clinical Guidance
Professor Jin has contributed to national expert guidance for pemphigus, paraneoplastic pemphigus, and adult dermatomyositis. His representative academic work includes research on genetic associations in pustular psoriasis and serum proteomics in erythrodermic psoriasis.
Guidelines and research help clinicians make decisions, but they do not replace an individualized examination, pathology review, or assessment for systemic disease.
Who May Consider a Consultation?
A consultation with Professor Jin or the PUMCH dermatology team may be worth considering when a patient:
- has a severe, rare, or difficult-to-diagnose skin disorder;
- has suspected dermatomyositis or cutaneous lupus;
- has painful blisters or erosions suggesting autoimmune blistering disease;
- has a rash with muscle weakness, lung symptoms, fever, or other systemic signs;
- has severe psoriasis or has not responded to standard treatment;
- has recurrent vasculitis, ulcers, or unexplained purple skin lesions;
- needs expert dermatopathology correlation; or
- needs a second opinion before long-term immunosuppressive or biologic treatment.
Medical Records to Prepare
International patients should prepare:
- a concise medical summary and chronological symptom history;
- clear photographs showing how the skin findings changed over time;
- dermatology, rheumatology, and hospital records;
- skin biopsy reports, glass slides, paraffin blocks, and immunofluorescence results when available;
- autoimmune antibody tests and inflammatory markers;
- muscle enzymes, chest CT, lung-function tests, or other organ assessments when relevant;
- bacterial, fungal, viral, or other microbiology results;
- a complete list of current and previous medicines, response, and side effects;
- details of previous laser or procedural treatment; and
- a clear list of questions for the specialist.
Whenever possible, photographs should be taken in consistent lighting and should include images from before treatment.
Planning an International Consultation
Appointments with senior specialists may be limited. Before traveling, patients should confirm whether records and photographs can be reviewed, whether an in-person skin examination is required, and whether pathology needs to be re-examined.
Remote medical-record review is subject to physician authorization. Many dermatologic diagnoses depend on direct examination and biopsy correlation, so a final diagnosis may still require an in-person visit.
How CMCS Can Assist
CMCS – China Medical Concierge Shanghai is an independent medical concierge and health management company, not a hospital. We assist international patients with organizing and translating medical records, identifying an appropriate specialist, requesting appointment availability, arranging interpretation, and planning medical travel in China.
Access to Professor Jin, remote review, pathology review, laser treatment, or any specific therapy is subject to the doctor’s and hospital’s approval. CMCS does not guarantee appointments, treatment eligibility, or clinical outcomes.
