6. Itching: Itchy skin is a common symptom.
7. Cracking: The skin may crack, leading to pain and bleeding.
8. Honeycomb Rash: In honeycomb pattern paraneoplastic pemphigus, a distinct rash with a honeycomb-like appearance may be present.
9. Nail Changes: Abnormalities in the nails, such as thickening or separation from the nail bed, can occur.
10. Hair Loss: Hair loss may affect the affected areas of the skin.
11. General Weakness: Due to the underlying cancer, patients may experience fatigue and weakness.
12. Unexplained Weight Loss: Some individuals may lose weight without a clear cause.
13. Fever: Occasionally, a fever may be present.
14. Cough or Breathing Problems: In cases associated with lung cancer, respiratory symptoms may occur.
15. Swelling: Swelling of the hands or feet may happen in some cases.
16. Joint Pain: Joint pain or arthritis-like symptoms can occur.
17. Difficulty Swallowing: If esophageal cancer is involved, swallowing difficulties may arise.
18. Change in Bowel Habits: For those with colorectal cancer, bowel habits may change.
19. Urinary Symptoms: Bladder or kidney cancer cases may involve urinary symptoms.
20. Enlarged Lymph Nodes: Lymphoma-associated cases may have enlarged lymph nodes.

Diagnostic Tests:

1. Skin Biopsy: A small piece of affected skin is removed and examined under a microscope to confirm paraneoplastic keratoderma.
2. Blood Tests: Blood samples are analyzed for markers related to cancer.
3. Imaging Scans: X-rays, CT scans, or MRIs can identify tumors or abnormalities.
4. PET Scan: Positron emission tomography can help pinpoint cancerous areas.
5. Endoscopy: A flexible tube with a camera can examine the digestive tract.
6. Chest X-ray: Used to detect lung cancer.
7. Mammogram: For breast cancer evaluation.
8. Pap Smear: To check for cervical cancer.
9. Prostate Specific Antigen (PSA) Test: For prostate cancer screening.
10. Bone Marrow Biopsy: Helps diagnose leukemia.
11. Colonoscopy: Examines the colon for colorectal cancer.
12. Cystoscopy: Checks for bladder cancer.
13. Liver Function Tests: Assess liver cancer.
14. Tumor Marker Tests: Measures specific substances associated with certain cancers.
15. Bronchoscopy: Evaluates lung and airway issues.
16. Ultrasound: Useful for detecting ovarian or testicular cancer.
17. Gastroscopy: Views the stomach and upper digestive tract.
18. Lymph Node Biopsy: To examine lymphoma involvement.
19. Stool Tests: For colorectal cancer screening.
