Hamartomas are usually asymptomatic. However, in some cases such as hypothalamic hamartomas and pulmonary hamartomas, symptoms may be more noticeable. Common symptoms of hypothalamic hamartomas include seizures, visual problems, early onset of puberty, and behavioral problems. Symptoms of pulmonary hamartoma may result from respiratory obstruction and include chronic cough, hemoptysis, or fever. It is important to obtain the history about familial inheritance, as it provides insight into the associated conditions.

History and Symptoms

Obtaining the history is an important aspect of making the diagnosis of inherited hamartomatous syndromes. It provides insight into the cause, and associated conditions. Complete family history can help determine the prognosis. Specific histories about the associated symptoms should be obtained. Specific areas of focus when obtaining the history, are outlined below:


Family history for other inherited hamartomatous syndromes


The majority of patients with hamartomas are asymptomatic.

Common Symptoms


  • Gelastic seizures have a typically of short duration (2-30 seconds) and are characterized by uncontrollable laughter, without impairment of consciousness, where as frontotemporal gelastic seizure are usually longer lasting and can result in loss of consciousness. Very rarely children with hypothalamic hamartomas can enter into status gelasticus.[1]
  • Visual deficit
  • Early onset of puberty
  • Behavioural changes
