“…Skin changes mimicking Kaposi sarcoma, known as Stewart-Bluefarb syndrome, may develop in lower extremity AVMs. [75][76][77][78][79] Conversely, Kaposi sarcoma may be misdiagnosed as an AVM. 80 Advancement to this stage is commonly induced by puberty, trauma, and pregnancy.…”

“…17 Pseudo-Kaposi sarcoma has also been reported as being associated with trauma. [17][18][19][20] Recently, Trindade et al reported a case of pseudoKaposi sarcoma due to suction-socket lower limb prosthesis 7 that shares some of the features found in our biopsy, but their lesion did not show the promontory sign. Trindade et al specifically insisted that ''in contrast with patch stage lesions of Kaposi's sarcoma, proliferation of irregular jagged vascular channels, with slit-like lumina, surrounding pre-existing capillaries is not seen in lesions of pseudo-Kaposi's sarcoma.''…”

The promontory sign was described 27 years ago and it was claimed to be useful in the diagnosis of early stages of Kaposi sarcoma. However, it is not pathognomonic, because it has also been described in angiosarcoma and in benign vascular tumors. Some authors claim that some reactive vascular lesions known as pseudo-Kaposi do not present the promontory sign. We report the case of a vascular cutaneous lesion on the breast of a 75-year-old woman, which had a benign clinical behavior, and presented with the promontory sign. The lesion was made of tortuous dilated lymphatic tissue, and small capillaries with a lobular distribution. It was characterized by CD31 and D240 immunostaining, although no immunostaining for human herpesvirus 8 (HHV8) was found. The lesion spontaneously improved and eventually disappeared. It was thought to be secondary to a chronic trauma to the area due to a prolonged stance in bed in the emergency room.

“…Les principaux diagnostics différentiels discutés aux stades précoces sont une malformation vasculaire à bas débit, un hémangiome, qui présente également des signes d'activité hémodynamique au cours de sa phase de croissance, voire une néoplasie, en particulier vasculaire de type angiosarcome. La malformation lorsqu'elle est localisée à un membre inférieur peut également ressembler à un sarcome de Kaposi [8,9]. Par ailleurs, son caractère ionisant est un frein à la répétition des examens nécessaires au suivi des enfants.…”

Arteriovenous malformations are serious high-flow vascular malformations. Four progressive stages have been described: dormancy, expansion, destruction and heart failure. Progression from one stage to another is not systematic but depends on events - physiological or traumatic, sometimes iatrogenic. Pulsed Doppler imaging of venous waveforms and magnetic resonance imaging (MRI) are the most informative examinations for both diagnosis and follow-up of arteriovenous malformations.Arteriography and angio-MRI help guide treatment decisions. Treatment of the malformation must not be envisioned until it reaches a symptomatic stage. It most often combines an endovascular procedures and wide surgical excision. A syndromic form must be considered in cases of systemic angioma.
