- Pneumonia (pneumonia)
Blood, blood-forming organs – immune system (D50-D90).
- Anemia (anemia)
Skin and subcutaneous (L00-L99)
- Erythema nodosum (synonyms: nodular erythema, dermatitis contusiformis, erythema contusiforme; plural: erythemata nodosa) – granulomatous inflammation of the subcutis (subcutaneous fat), also called panniculitis, and painful nodulation (red to blue-red color; later brownish). The overlying skin is reddened. Localization: both lower leg extensor sides, on the knee and ankle joints; less frequently on the arms or buttocks.
Cardiovascular system (I00-I99).

Musculoskeletal system and connective tissue (M00-M99).
- Arthritis (inflammation of the joints)
Ears – mastoid process (H60-H95)
- Otitis media (inflammation of the middle ear)
Psyche – nervous system (F00-F99; G00-G99)
- Guillain-Barré syndrome (GBS; synonyms: Idiopathic polyradiculoneuritis, Landry-Guillain-Barré-Strohl syndrome); two courses: acute inflammatory demyelinating polyneuropathy or chronic inflammatory demyelinating polyneuropathy (peripheral nervous system disease); idiopathic polyneuritis (diseases of multiple nerves) of spinal nerve roots and peripheral nerves with ascending paralysis and painGBS is associated with M. pneumoniae infection; more common in children than in adults
- Meningitis (meningitis).
- Myelitis (inflammation of the spinal cord)
- Polyradiculitis – inflammation of multiple nerve roots.
Genitourinary system (kidneys, urinary tract – sex organs) (N00-N99)
