Heat Intolerance and Hyperhidrosis as the only Presenting Manifestations of Acromegaly: A Case Report

Abstract

Acromegaly is a state of Growth Hormone (GH) excess characterised by coarse facial features, acral enlargement, hyperhidrosis, headache, visual disturbances and visceromegaly. The most common cause of acromegaly is pituitary adenoma. The average delay between onset of symptoms and diagnosis is about six years in acromegaly owing to its subtle clinical features at the disease onset.Early diagnosis is important to reduce the morbidities and mortality associated with acromegaly. Familiarisation of physicians with the signs and symptoms of the disease is an effective strategy for the early diagnosis of acromegaly. Here, the authors report a case of 38year-old female patient. After proper clinical examination, history and series of relevant investigations, the serum GH level was estimated and was found to be elevated (40 ng/mL). GH secreting pituitary macroadenoma presenting with heat intolerance and hyperhidrosis without the classical manifestations of acromegaly.
