We report the case of a healthy 26-year-old man presenting telangiectatic macules on the left thorax and arm since childhood. The main diagnostic hypothesis were unilateral nevoid telangiectasia (UNT), hereditary benign telangiectasia, atrial myxoma, segmental serpiginous angioma, circumscribed neviform angiokeratoma, and nevus vascularis mixtus. The diagnosis retained was UNT characterized by congenital or acquired telangiectasia distributed asymmetrically along the upper extremities, or the third or fourth cervical dermatomes. Read More

Melorheostosis (MEL) is a rare benign bone disorder that can be associated with several anomalies, including vascular abnormalities, nevus sebaceus, unilateral nevoid telangiectasia, linear scleroderma and hypertrichosis. We report the case of a 6-year-old patient who showed an unusual co-occurrence of bone hyperostosis and different skin lesions affecting the same side of the body: MEL, verrucous epidermal nevus, connective tissue nevus, linear scleroderma-like disorder, hyperpigmentation and hypertrichosis. The spatial co-occurrence of these conditions made us speculate as to whether they originated from a common genetic mechanism or if their co-occurrence was completely accidental. Read More

Oral mucosal involvement in patients with morphea is quite rare. Unilateral nevoid telangiectasia is a rare vascular dermatosis characterized by unilateral telangiectasia distributed in a dermatomal pattern, especially on the upper trunk and extremities. We describe a case of a 10-year-old female patient that presents with morphea on her left chin and upper lip extending to the inner oral mucosa as well as a unilateral nevoid telangiectasia on her left cheek as an early presentation of localized scleroderma.

Cutaneous collagenous vasculopathy is a rare acquired idiopathic microangiopathy characterized by progressive development of diffuse asymptomatic telangiectasias and histologically by accumulation of collagen type IV around the affected vessels. It is diagnosed by its clinical history, confirmed by light microscopy with collagen-specific immunostaining. We report a case of a patient with extensive acquired telangiectasias on the left arm, clinically resembling unilateral nevoid telangiectasia. Read More

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.

Unilateral nevoid telangiectasia (UNT) is characterized by the dermatomal distribution of telangiectasia, which are distributed unilaterally and frequently found in C3-C4 or the trigeminal dermatomal areas. It may be congenital or acquired and has a 2:1 female: male ratio. Several theories where developed in order to explain its etiopathogenesis. Read More

Unilateral Nevoid Telangectasia Syndrome (UNTS) is characterized by superficial telangiectasias in a unilateral distribution. Vascular endothelial growth factor (VEGF) may play a role in the pathogenesis of UNTS in patients with underlying hepatic disease. We report a case of a patient with UNTS accompanied by chronic hepatitis C virus infection, with a normal serum estrogen profile and strong positive immunohistochemical staining of lesional skin with VEGF.

A 55-year-old Caucasian man presented with unilateral right facial spider nevi. Relevant medical history included a right-sided cerebrovascular accident (CVA) in 1997 and decompensated alcoholic liver disease, diagnosed in 2007. The literature describes approximately 100 cases of unilateral spider nevi associated with different aetiologies, grouped under 'unilateral nevoid telangiectasia syndrome' (UNTS). Read More

A 27 year-old-man, with no known personal or familial history of disease, mentioned a 10-year history of asymptomatic groups of telangiectasias, with a Blaschko lines distribution on the right lateral aspect of the neck and asymptomatic. He denied any episodes of disease or drug intake that could be associated with the disease. Blood work had no changes, namely of liver enzymes or infectious serologies. Read More

Unilateral nevoid telangiectasia is a rare congenital or acquired disorder. The majority of the authors propose that it is probably related to elevated estrogen receptors, although other authors advocate different theories. We report the occurrence of lesions clinically compatible with this diagnosis in a child and two adults. Read More

Melorheostosis is a rare disorder characterized by irregular, flowing hyperostosis in long bones, commonly described on radiographs as wax flowing down a candle. In addition to bony sclerosis, cutaneous manifestations overlying the involved bones have been reported including linear scleroderma, neurofibromatosis, and vascular and lymphatic malformations. Unilateral nevoid telangiectasia (UNT) is a rare primarily cutaneous condition characterized by linearly arranged small dilated blood vessels in dermatomal or Blaschkoid patterns on the skin.
