Pulmonary involvement symptoms are similar to tuberculosis (TB), and include fever, fatigue, weight loss, and coughing up blood. Diarrhea and abdominal pain are associated with gastrointestinal involvement. Children M.<unk>  and M. haemophilum infections in children form a distinct clinical entity, not associated with abnormalities of the immune system. M.<unk>  typically causes unilateral swelling of one of the lymph nodes of the neck. This node is firm at the beginning, but a 'collar-stud' abscess is formed eventually, which is a characteristic blue-purple in colour with multiple discharging sinuses. The treatment of choice is surgical excision of the affected lymph nodes, with antibiotic treatment (usually clarithromycin and rifabutin for 18 to 24 months) reserved for those patients who cannot have surgery.
