Insights
This case study highlights a rare vascular Ehlers-Danlos syndrome (vEDS) diagnosis in a young male with a complex medical history. The study details the diagnostic challenges posed by overlapping symptoms with Marfan syndrome and transient antiphospholipid antibodies.
Area of Science:
- Genetics and rare diseases
- Vascular pathology
- Connective tissue disorders
Background:
- Ehlers-Danlos syndrome (EDS) encompasses a group of inherited connective tissue disorders.
- Vascular EDS (vEDS), specifically type IV, is characterized by arterial and organ rupture.
- Differential diagnosis often involves conditions with overlapping phenotypes like Marfan syndrome.
Observation:
- A 19-year-old male presented with a history of easy bruising, skin lesions, and spontaneous colonic perforation.
- He later developed bilateral renal infarctions and hypertension due to renal artery dissection.
- Transient antiphospholipid antibodies (aPL) and elastosis perforans serpiginosa were noted on investigations.
Findings:
- The patient's clinical presentation, family history, and diagnostic findings supported a diagnosis of vascular Ehlers-Danlos syndrome, type IV.
- The physical characteristics were similar to Marfan syndrome, complicating the diagnosis.
- Transient aPL elevations presented a diagnostic and management challenge.
Implications:
- This case underscores the importance of recognizing the diverse and overlapping clinical manifestations of connective tissue disorders.
- Accurate diagnosis of vEDS is critical for appropriate management and genetic counseling.
- The presence of transient aPL requires careful consideration in the diagnostic workup of vascular events.
Abstract:
We describe a 19-year-old male, with a family history of both systemic lupus erythematosus and Marfan syndrome, who had a history of bruising easily and skin lesions since childhood. He had a spontaneous colonic perforation at the age of 16 years, followed 3 years later by sudden development of bilateral renal infarctions and hypertension, which on angiography were found to be due to dissection of both renal arteries. Transient elevations of 3 types of antiphospholipid antibodies (aPL) were detected. Skin biopsy showed typical elastosis perforans serpiginosa. The history together with the generalized connective tissue phenotype, histology, and angiographic features combined to establish a diagnosis of vascular Ehlers-Danlos syndrome, type IV; the body habitus resembled the phenotypically-related condition of Marfan syndrome. The coincidental finding of transient aPL elevations combined to make this a difficult diagnostic and clinical management problem.
