Other diseases that cause enlargement of the lymph nodes may include:

  • Bacterial, viral or fungal infections. An infection can cause enlargement of one or more lymph nodes. In localized infections, the lymph node that normally drains the affected region of the body typically becomes enlarged.

  • Immune-mediated diseases. These diseases occur when the immune system fails to recognize parts of the body and begins to attack normal tissues. Systemic lupus erythematosus is an example of a body wide immune-mediated disease.

  • Severe skin diseases (especially chronic bacterial infections, or systemic demodectic mange) can cause enlargement of external lymph nodes.

  • Other cancers can cause enlargement of one or more lymph nodes due to spread (metastasis) of the tumor by way of the lymphatic system.

    Other diseases that can vomiting, diarrhea, weight loss, decreased appetite include:

  • Infections.
    Viruses such as the coronavirus that causes feline infectious peritonitis can cause gastrointestinal symptoms.

  • Inflammatory bowel disease (inflammation of the intestine due to a variety of causes) can cause vomiting and diarrhea and prevent proper digestion.

  • Other intestinal tumors (intestinal adenocarcinoma, intestinal leiomyosarcoma, mast cell tumor) can cause vomiting or diarrhea.

  • Metabolic diseases such as hypoadrenocorticism ("Addison's disease"), diabetes mellitus, liver disease, or kidney disease.

    Other diseases that can cause difficulty breathing may include:

  • Heart failure with fluid accumulation in the lungs (pulmonary edema) or in the chest cavity (pleural effusion).

  • Respiratory infections such as pneumonia can cause coughing, increased respiratory rate, and difficulty breathing.

  • Tumors originating in the lungs or those that have spread (metastasized) to the lungs from other sites can cause difficulty breathing.
