Osler-Weber-Rendu syndrome, also known as hereditary hemorrhagic telangiectasia, is a rare autosomal dominant disorder manifested by telangiectases of the skin and mucous membranes and arteriovenous malformations of various organ systems. We report a case of 45-year-old postmenopausal woman who presented to dermatology department for evaluation of compressible vascular lesion involving bilateral palms and oral cavity for the past 3 months' duration. On further evaluation, she was found to have portal hypertension and multiple cavernoma formation on place of portal vein.

| Introduction|| |
Osler-Weber-Rendu syndrome (OWRS) or hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant disorder with incidence of 1–2 cases/100,000 population. arteriovenous malformations (AVM) and the associated hemorrhage.
Symptoms and signs may present at the age of 40 years. HHT occurs with equal frequency and severity in males and females. HHT has a higher prevalence in certain populations, such as the Afro-Caribbean residents of Curacao and Bonaire. The major cause of morbidity and mortality lies in the presence of multiorgan AVM and the associated hemorrhage.
Epistaxis is the most common (96%) and first clinical manifestation, followed by cutaneous telangiectasias (75%). The vascular malformations may involve lungs, liver, kidney, and brain. Portal venous hypertension is reported (<10%) with OWRS.
We report a case fulfilling all major criteria for OWRS with esophageal varices due to portal hypertension.
| Case Report|| |
A 45-year-old postmenopausal female born to nonconsanguineous parents presented with multiple red asymptomatic lesions on the tongue [Figure 1]a and both palms [Figure 1]b of 3 months' duration along with epistaxis for the past 9 months (frequency being once in 3 months). She had a history of recurrent spontaneous severe bleeding from the lesions even on mild trauma. There was no history of bleeding from any other sites. There was a history of similar lesions being present in her mother.

Dermatologically, multiple erythematous macular blanchable lesions on both palms, multiple erythematous compressible non-pulsatile papulonodular lesions on the tongue, and multiple petechiae over the palate were evident. Dermoscopy revealed multiple radiating linear vessels and histopathology revealed multiple ectatic capillaries [Figure 2]a and [Figure 2]b. We considered differential diagnosis such as angiokeratoma, portal hypertension-induced vascular ectasia, and OWRS.

Blood investigations such as complete blood count, renal and liver function tests, coagulation profile, and direct and indirect coombs test revealed no abnormalities. Ultrasonography of abdomen revealed portal hypertension (portal vein was replaced by multiple collaterals suggesting possibility of cavernous formation). Multiple collaterals noted in peripancreatic, peri-gallbladder, umbilical, and RIF region. Marked periportal and perigallbladder cuffing is noted) and early changes of adenomyosis. Upper gastrointestinal (GI) scopy revealed small esophageal varix. On ophthalmic examination, pinpoint hemorrhage in the left lower palpebral conjunctiva was seen. On fundoscopic examination, no AVM was seen. Magnetic resonance imaging of brain revealed no vascular abnormality.
| Discussion|| |
The curacao diagnostic criteria is used for the diagnosis of OWRS.
- Epistaxis: Spontaneous, recurrent nose bleeds
- Cutaneous and mucosal telangiectasia: Multiple, at characteristic sites (lips, oral cavity, fingers, and nose)
- Visceral lesions: GI telangiectasia (with or without bleeding) and AVM (pulmonary, hepatic, cerebral, and spinal)
- Family history: A first-degree relative with HHT.
The presence of three criteria makes a definite diagnosis and two are needed for a possible diagnosis. Our patient fulfilled all four criteria.
HHT type-1 and 2 are due to defective endoglin and activin receptor-like kinase (ALK1) genes, on chromosome 9 and 12, respectively. HHT type-3 involves mutations on chromosome 5 (5q31.1–32) and type-4 maps to the chromosome 7 (7p14). A HHT-juvenile polyposis overlap syndrome due to mutations of SMAD4 has also been described. Patients with the HHT Type-1 genotype have higher prevalence of pulmonary and cerebral AVM, and more severe GI bleeding while, the prevalence of hepatic AVM is higher in patients with HHT type-2. We were unable to do genetic test because of its nonavailability. Although the precise mechanism remains poorly understood, bleeding tendency in HHT is attributed to localized vessel wall weakness.
HHT is a common cause of hepatic involvement in the form of focal nodular hyperplasia and hepatic AVMS, more commonly reported with ALK1 mutation with a prevalence of up to 84%. However, portal hypertension is uncommon with presence in <10% patients. Portal hypertension and hepatic encephalopathy more commonly appear to result from increased sinusoidal blood flow, leading to enhanced deposition of fibrous tissue, and pseudo cirrhosis of the liver., Index case had normal size and normal echopattern of liver but findings of portal hypertension were seen.
Although not described in our patient, ocular manifestations are of interest. This includes ocular signs and symptoms such as bloody tears, conjunctival posthemorrhagic granulomatous lesions, and telangiectasias at the level of the conjunctiva (most common ocular finding) and posterior pole, retinal vascular malformation, choroidal telangiectasia, retinal telangiectasia, and AVM.
Asymptomatic portal hypertension, pulmonary, and cerebral AVM with hemorrhagic or embolic complications (brain abscess and stroke) are responsible for most of the HHT's mortality rate (10%). Our patient also had asymptomatic portal hypertension. It is crucial that a long-term follow-up for the identification of potential complications is maintained and patients are counseled regarding the autosomal dominant nature of the condition.
Neurological manifestations are more common in those with pulmonary arteriovenous fistula than in those with cerebrovascular malformations.
Various histopathological findings as per other reports are described [Table 1].,
Surveillance guidelines include annual investigation for anemia and a neurological examination. The patient should be screened for pulmonary artery AVM and a contrast echocardiogram performed if saturation is less the 97%.
The varied treatment modalities described includes estrogen, Î-amino-caproic acid, cryotherapy, cautery, infrared coagulation, radiofrequency, pulse dye laser, Nd-YAG laser, and surgical ablation.
This case is being reported because of its rarity and for general awareness regarding the disease among dermatologist. In addition, our case also had rare manifestation in the form of portal hypertension for which patient needs to be observed.
