The pathophysiology of generalized essential telangiectasia is not well understood. Generalized essential telangiectasia is an uncommon disorder in which widespread telangiectasias of unknown cause develop without associated systemic or antecedent dermatologic disease. We report a case of generalized essential telangiectasia in an otherwise healthy 49-year-old man. Read More

Cutaneous collagenous vasculopathy (CCV) is a rare benign microangiopathy of the superficial dermal vessels. Clinically, it is characterized by widespread, asymptomatic development of cutaneous telangiectasia in the absence of systemic symptoms. Morphologically, it most resembles generalized essential telangiectasia and other telangiectatic syndromes such as telangiectasia macularis eruptiva perstans (TMEP), ataxia telangiectasia, and hereditary hemorrhagic telangiectasia.

Essential generalized telangiectasia as the result of postcapillary venule dilatation, is characterized by the sudden development of generalized telangiectasias, sometimes involving the conjunctiva. A few pediatric cases have been reported. The main condition in the differential diagnosis includes syndromes with telangiectasia such as hereditary hemorrhagic telangiectasia of Rendu-Osler, unilateral nevoid telangiectasia, and neonatal lupus erythematous.

Generalized essential telangiectasia (GET) is a notoriously difficult to treat disorder with no current satisfactory treatments. This case and discussion report the use of 6-mercaptopurine (6-MP) as a successful treatment for GET. Moreover, we show that GET may represent a state of increased angiogenesis, a paradigm shift from the current understanding that these telangiectasias represent dilatations of only pre-existing vessels.

The late development of symmetrical, ascending telangiectasias over an extensive area of the skin with no associated systemic manifestations is a common presentation of generalized essential telangiectasia (GET). It was recently suggested that cutaneous collagenous vasculopathy (CCV) is clinically identical to GET but that the 2 conditions can be distinguished by their distinctive histopathologic findings. We present 2 patients, both women, with multiple telangiectasias and describe the histopathologic findings that led to the diagnoses of GET and CCV. Read More

Cutaneous collagenous vasculopathy (CCV) is a distinct, rare, and underdiagnosed condition. We report a case of CCV in a 50-year-old woman presenting as asymptomatic, erythematous to hyperpigmented nonblanchable macules over both the lower extremities. The clinical differential diagnosis of the lesions was pigmented purpuric dermatoses (Schamberg's purpura) and cutaneous small vessel vasculitis. Read More

Cutaneous collagenous vasculopathy is a rare microangiopathy of dermal blood vessels. Clinically indistinguishable from generalized essential telangiectasia, this condition is diagnosed by its unique histological appearance. In contrast to other primary telangiectatic processes, cutaneous collagenous vasculopathy has dilated vascular structures that contain deposits of eosinophilic hyaline material within the vessel walls.

Cutaneous collagenous vasculopathy is a rare cutaneous microangiopathy of unknown aetiology with only 27 cases reported to date. It is characterised clinically by generalised cutaneous telangiectasias and microscopically by dilation and marked thickening of the walls of superficial dermal blood vessels. Differential diagnosis should be performed with other causes of disseminated telangiectasias, including generalised essential telangiectasia, from which it is clinically indistinguishable. Read More

Generalized essential telangiectasia (GET) is a rare skin condition of unknown aetiology. We report a case of a 39-year-old man who presented to the ophthalmology department with reduced vision, and was diagnosed with generalized essential telangiectasia by indocyanine green and fluorescein angiography of his eyes. The patient was noted to have corneal neovascularization (which was responsible for his reduced visual acuity) and conjunctival telangiectases seen by angiography. Read More

Cutaneous collagenous vasculopathy (CCV) is a rare distinct idiopathic microangiopathy of the superficial cutaneous vasculature. Seven new cases are reported (6 females and 1 male) ranging in age from 42 to 85 years, with some showing unusual clinical and histopathological findings. All presented with macular telangiectases starting on the lower extremities and spreading progressively in 5 cases and were suspected to have generalized essential telangiectasia. Read More

Cutaneous collagenous vasculopathy (CCV) is a rare cutaneous microangiopathy that clinically resembles generalized essential telangiectasia with only 12 cases reported to date. The perivascular fibrosis is thought to be due to production of abnormal collagen by veil cells in the outer vessel walls as a result of unknown factors. This report is of an 84-year-old male with progressive telangiectasia. Read More

Generalized essential telangiectasia, which is a rare condition that is characterized by the progressive development of telangiectases on the skin, is a clinical diagnosis of exclusion. We present a 65-year-old man with a ten-month history of an asymptomatic eruption of the trunk and proximal aspects of the arms and hands that was comprised of macules and patches of telangiectases. The clinical presentation, associated diseases, hypotheses regarding pathogenesis, differential diagnoses, and reports on treatment modalities are reviewed. Read More

Cutaneous collagenous vasculopathy is characterized by generalized cutaneous telangiectasia and unique microscopic and ultrastructural vascular changes, consisting of marked collagen deposition within the vascular walls of the post-capillary venules in the superficial dermis. There are only 4 previous cases described in the medical literature, all in males, mostly middle-aged. We have recently seen two female patients with clinical and histopathologic features diagnostic of cutaneous collagenous vasculopathy, indicating that it is not restricted to males. Read More

Cutaneous collagenous vasculopathy (CCV) is an idiopathic microangiopathy involving the superficial blood vessels that was initially reported in a 54-year-old male. We recently have identified this rarely reported entity in three Caucasian males.

Atm-deficient mice die of malignant thymic lymphomas characterized by translocations within the Tcr alpha/delta locus, suggesting that tumorigenesis is secondary to aberrant responses to double-stranded DNA (dsDNA) breaks that occur during RAG-dependent V(D)J recombination. We recently demonstrated that development of thymic lymphoma in Atm(-/-) mice was not prevented by loss of RAG-2. Thymic lymphomas that developed in Rag2(-/-) Atm(-/-) mice contained multiple chromosomal abnormalities, but none of these involved the Tcr alpha/delta locus. Read More

Generalized essential telangiectasia is a rare skin disorder characterized by the development of dilated venules beginning at the lower extremities and progressively spreading out to the rest of the body.

Generalized essential telangiectasia (GET), as originally described, is not associated with any underlying disease. Although patients with GET lack the typical periungual telangiectases associated with autoimmune collagen vascular diseases, these patients may have an underlying autoimmune process.
