Question: A 17-year-old boy presented with a swollen head. One month earlier, he had been hit in the head with a basketball during a game, and he had developed progressive swelling a few days later. The patient did not have any history of bruising or bleeding except recurrent, self-limited epistaxis, but he did have a history of fever (up to 39°C), 30-kg weight loss, and pancytopenia (in the presence of trilineage cellular hypoplasia on bone marrow biopsy) that lasted 4 months after contracting infectious mononucleosis (seroconversion confirmed by positive immunoglobulin [Ig]M antibodies) treated with the antiviral agent cidofovir. The patient also had a prior history of refractory iron-deficiency anemia (not alleviated by oral iron therapy). The maternal grandfather (age 72 years) had the same gastroduodenal condition, severe refractory iron-deficiency anemia requiring intravenous iron therapy, and bilateral renal artery and aortic aneurysms. The mother was healthy, and a sister (age 22 years) was healthy except for a borderline low platelet count.

Physical examination showed circumferential symmetrical enlargement of the head, accentuated at the temples, with a subcutaneous fluctuant fluid collection. He had slightly prominent eyes, a pinched nose, a webbed neck, kyphosis, hyperextensible digits, and pectus excavatum. He also had splenomegaly, mildly extensible and translucent skin without a history of poor wound healing, and numerous 1-mm telangiectatic lesions on the trunk and legs. Laboratory analyses revealed anemia, thrombocytopenia, and mildly elevated lactate dehydrogenase and aspartate aminotransferase levels (Table 1). On biopsy, the bone marrow was hypocellular (25% cellularity) with low iron stores and diploidy, no Epstein–Barr virus (EBV) particles were detected, and normal, adequate megakaryocytes were present. A non–contrast-enhanced computed tomography (CT) scan of the head was obtained (Figure A). Gastroduodenal endoscopy (Figure B) and colonoscopy (Figure C) were performed. His older brother had presented with severe pancytopenia owing to aplastic anemia and iron malabsorption at age 16 years. He had pectus excavatum, hyperextensible finger joints, avascular necrosis of the hips and shoulders, and similar gastroduodenal abnormalities. The brother died 2 years later of massive intracranial hemorrhage.

Answer to the Clinical Challenges and Images in GI Question: Image 2: Extensive Bilateral Extracranial Subcutaneous Fluid Collection 

An extensive bilateral extracranial subcutaneous fluid collection (Figure A, arrows) was responsible for the swelling that prompted presentation. The cystic component superiorly and more solid-appearing blood clotting inferiorly was consistent with extracranial subgaleal hematoma. No intracranial fluid collection or skull fracture was evident. A cerebral magnetic resonance angiogram (MRA) and CT scans of the chest, abdomen, and pelvis were normal.

The patient was treated by transcutaneous needle aspiration, which returned a motor-oil–like fluid consistent with old, hemolyzed blood. The hematoma resolved and did not reaccumulate. The upper gastroduodenal endoscopy revealed vascular ectasia in the stomach and numerous telangiectases in the duodenum (Figure B), and the colonoscopy showed cecal vascular ectasias (Figure C, arrow).

Possible diagnoses considered were Ehlers–Danlos syndrome disease and hereditary hemorrhagic telangiectasia, but not all the patient's clinical features were consistent with these syndromes (Table 2).1 The patient was referred for genetic counseling and testing, but without a final identifiable diagnosis. The patient died at home 1 year later of massive intracranial hemorrhage, possibly secondary to a ruptured cerebral aneurysm not visualized on the cerebral MRA performed earlier. Permission for an autopsy was not granted.

Clinical FeaturesEhlers-Danlos Syndrome, Classic or Vascular Type (Type IV)Hereditary Hemorrhagic Telangiectasia Types 1 and 2 (Rendu–Osler–Weber Syndrome)Patient Presented (DELTA PHI Syndrome)
Blood vesselsFragile blood vessels and organs that are prone to rupture secondary to defects in fibrillar–collagen metabolismMucosal telangiectases are universal, occur as early as age 10–21 y, but are more severe after age 40; typically affecting nasal mucosa, with various degrees of epistaxis (90%)Telangiectases of the mucosa of the nose with epistaxis (in early teens)
SkinSkin telangiectases are universal but occur later in life, typically on tongue, lips, conjunctiva, arms and trunk, fingertips, nails, and ears (13%–89%)Telangiectases of skin
Fragile skin that bruises easily, delayed healing and atrophic scars
Thin, translucent skin (veins visible beneath)Thin, translucent skin (veins visible beneath)
Hyperextensible skinHyperextensible skin
MucosaAVM predominate in certain forms: pulmonary AVM (5%–15%) causing hemoptysis and right-to-left shunting (cyanosis, clubbing, bruit cerebral abscesses, paradoxical emboli); hepatic AVM (8%–30%) causing high-output heart failure and portal hypertension; brain and spinal AVM (5%–11%) causing seizure, intracerebral hemorrhage, and headacheFamily history of aortic and renal arterial aneurysms (grandfather) and intracranial aneurysms (brother and patient)
GI telangiectases, AVM (11%–40%), and iron-deficiency anemia; bleeding is rare and occurs after fifth decade (<2%)Gastrointestinal telangiectases; both patient and brother had bleeding in their teens
Kyphosis, webbed neck, pectus excavatum
JointsHypermobility of joints (usually limited to the fingers and toes)Hypermobility of joints (fingers and toes)
MaxillofacialDistinctive facial features: sunken cheeks and small chinFacial changes, small chin
Protruding eyesProminent eyes
Thin nose and lipsMildly pinched, thin nose
Family historyColonic diverticula, but no upper GI diverticula
Aortic, renal, and brain aneurysms
Avascular necrosis of hips and shoulders in brother
Laboratory and genetic findingsIron-deficiency anemia from epistaxisIron-deficiency anemia
Iron malabsorption
Bone marrow failure with pancytopenia: thrombocytopenia, leukopenia
Genetically heterogeneous group: (1) Autosomal-dominant disorder (classic variant), mutations in COL3A1 gene; (2) homozygous tenascin-X gene (TNXB) mutations or deletionsAutosomal-dominant disorder: Mutations in ACVRL1, ENG, and SMAD4 genesUnknown, suspected

This patient and his brother seem to have a new syndrome with some features of both Ehlers–Danlos syndrome (hyperextensible and translucent skin, hypermobile joints, and dysmorphic facial features)2 and hereditary hemorrhagic telangiectasia (mucosal and skin telangiectases, iron-deficiency anemia, and mucosal and brain arteriovenous malformations)3 plus unique signs such as dysmorphic musculoskeletal anomalies (kyphosis and pectus excavatum), iron malabsorption, bone marrow failure, arterial aneurysms, and avascular necrosis of the hips. A suggested name for the syndrome is “familial DELTA PHI syndrome,” emphasizing the combination of dysmorphic features, epistaxis, laxity of joints, telangiectasia, aneurysms, pancytopenia, hyperextensible skin, and iron malabsorption. Further cases remain to be identified and genetic exploration is warranted for identification of the molecular pathophysiology.
