Pseudoacromegaly is a extremely rare condition previously described and characterized by acromegaloid changes, tissue overgrowth, without elevations in insulin-like growth factor or growth hormone as seen in Acromegaly. We present the case of a young female seen initially with acromegaloid features and a pituitary microadenoma. After work-up the patient was diagnosed as insulin-mediated pseudoacromegaly. Only a few cases of pseudoacromegaly has been reported and should always be considered when evaluating patients for acromegaloid features with negative biochemical and hormonal levels.

Primary disease of adipose tissue: When to think about and how to evaluate it in clinical practice?

Article Synopsis
  • Primary diseases of adipose tissue, such as lipodystrophy syndromes, involve issues with fat storage and hormonal functions, leading to health problems like insulin resistance and cardiovascular complications.
  • These disorders can be congenital or acquired, and their diagnosis is often overlooked or delayed, making it crucial for physicians to recognize specific clinical signs and associated conditions.
  • Young diabetes patients with low BMI and signs like acanthosis nigricans should be evaluated for lipodystrophy, particularly if there's a family history of cardiovascular disease, as this may indicate familial forms like Dunnigan syndrome.

Pseudoacromegaly-A challenging entity in the endocrine clinic: A systematic review.

Clin Endocrinol (Oxf)

June 2024

Centre for Endocrinology, William Harvey Research Institute, Barts and the London School of Medicine and Dentistry, Queen Mary University of London, London, UK.

Article Synopsis
  • Pseudoacromegaly refers to conditions that show symptoms similar to acromegaly or gigantism but do not involve excess growth hormone (GH) or insulin-like growth factor-1 (IGF-1).
  • A systematic review of 76 cases revealed that most patients were males, with common conditions being pachydermoperiostosis and insulin-mediated pseudoacromegaly, and symptoms like acromegaloid facies and acral enlargement.
  • The study emphasizes the importance of thorough GH and IGF-1 testing by endocrinologists to accurately exclude acromegaly, as misdiagnosis can lead to unnecessary interventions, especially regarding pituitary findings.

Analysis of disease characteristics of a large patient cohort with congenital generalized lipodystrophy from the Middle East and North Africa.

Background: Congenital generalized lipodystrophy (CGL) is a rare inherited disease characterized by a near-total absence of adipose tissue and is associated with organ system abnormalities and severe metabolic complications. Here, we have analyzed the disease characteristics of the largest CGL cohort from the Middle East and North Africa (MENA) who have not received lipodystrophy-specific treatment.

Methods: CGL was diagnosed clinically by treating physicians through physical assessment and supported by genetic analysis, fat loss patterns, family history, and the presence of parental consanguinity.

Acromegaly and gigantism are hormonal disorders which develop as a consequence of chronic growth hormone hypersecretion. The prefix pseudo- is used to describe a certain clinical condition without a clearly proven characteristic of pathophysiological mechanism and basic biochemical features; pseudoacromegaly or acromegaloidism match the definition from above. In this case reports, we will try to provide a concise overview of diagnostic evaluation of acromegaloid physical appearance, while discussing two cases of patients who have similar clinical acromegaloid features as the first sign of the disease but have completely different etiologic backgrounds of their acromegalic appearance.

Congenital Generalized Lipodystrophy (CGL) is a rare autosomal recessive disease characterized by near complete absence of functional adipose tissue from birth. CGL diagnosis can be based on clinical data including acromegaloid features, acanthosis nigricans, reduction of total body fat, muscular hypertrophy, and protrusion of the umbilical scar. The identification and knowledge of CGL by the health care professionals is crucial once it is associated with severe and precocious cardiometabolic complications and poor outcome.
