Hypothyroidism: diversity of presentation.

Hypothyroidism has a number of signs and symptoms known to most all clinicians. However, the disorder has many other presentations that are less frequently recognized. These other manifestations, though not seen often, are also not uncommon. Hypothyroidism is an easily treated, frequent disease, and can be misdiagnosed for years before becoming apparent. Although its symptoms are usually readily reversible with treatment, lack of recognition of its rarer signs and symptoms can lead to unnecessary morbidity. Awareness of the diversity of presentation of this disease may lead to early, effective treatment.
