Cutaneous angiosarcoma: the role of dermoscopy to reduce the risk of a delayed diagnosis

A case of epithelioid angiosarcoma in a young man with chronic lymphedema

“…Dermoscopic examination can help the clinician by revealing the classic colors of vascular lesions, graduation of red, purple, and blue. Various color gradiation may be an important dermoscopic feature of cutaneous angiosarcoma, In addition, cutaneous angiosarcoma is characterized by the absence of welldefined vascular structures with patchy whitish and purpule veil [5], similar to the features found in our case.…”

Dermatoscopic and ultra‐high frequency ultrasound evaluation in cutaneous postradiation angiosarcoma

“…Referring to the features described by Wortsman et al, 7,8 we included the following features: characterization of the hair follicles (normal or widened hypoechoic bands); the dermal echogenicity surrounding the hair follicles (homogeneous or heterogeneous); apparent epidermal bulging (presence or absence); focal hypoechoic dermal area <5 mm (presence or absence); and pseudocyst defined as round or oval-shaped structures ≥5 mm (presence or absence).…”

“…1 The diagnosis of cAS may be difficult also for the pathologists and the tumour may be misdiagnosed as a benign vascular lesion. 2 Dermatoscopy [3][4][5][6][7][8][9] and ultrasonography [9][10] in cAS may allow clinicians to perform an early diagnosis. Dermatoscopy may show the presence of bluish, reddish or yellowish areas, white lines or veils, white follicular outlets, different vascular pattern, or pink-purple 'steam-like areas'.…”

“…Dermatoscopy may show the presence of bluish, reddish or yellowish areas, white lines or veils, white follicular outlets, different vascular pattern, or pink-purple 'steam-like areas'. [3][4][5][6][7][8][9] The main dermatoscopic differential diagnoses are other vascular tumours, such as infantile haemangioma in children or Kaposi sarcoma, and non-vascular tumours laking specific dermatoscopic features, such as amelanotic melanoma, Merkel cell carcinoma and primary cutaneous B-cell lymphoma. 5 The high-frequency ultrasound (18 MHz probe) shows a hypoechoic well-defined vascularized lesion.…”

A case of Stewart–Treves Syndrome of the lower limbs: The usefulness of dermoscopy

“…Immunochemistry is frequently needed to establish the diagnosis: angiosarcomas may typically express CD31, CD34, D2‐40, and ERG . Dermoscopic examination may help the dermatologist showing the classic colours of vascular lesions: a graduation of red, purple, and blue . Various colour gradation could be an important dermoscopic feature of this kind of tumour as it is not found in other vascular lesions, such as common purpura and ecchymosis .…”
