“…Ulcers [10][11], epidermoid cysts [8,10], Kaposi-like sarcoma [12][13], and verrucous hyperplasia [10,[14][15] are skin conditions that are attributed to external pressures applied to the residual limb. Sustaining proper circulation and fluid exchange in the soft tissues is imperative for maintaining a healthy residual limb.…”

A common mode of limb suspension for transtibial amputees is the pin liner/shuttle lock system. Despite its popularity, some clinicians question its use because of observed daily and chronic changes to the residual limb. For this study, we measured limb interface pressures during ambulation with pin and suction suspension systems. No pressure differences were seen between the modes of suspension during stance phase. However, during swing phase, pin suspension maintained an average occlusive compressive pressure of 6.7 kPa on the proximal tissues, as compared to the subocclusive pressure of 1.1 kPa with suction suspension. Simultaneously, pin suspension elevated the peak magnitude of suction to -39.5 kPa at the distal residual limb, compared to -26.1 kPa with suction suspension. During swing phase, the pin liner squeezes proximally while creating a large suction distally on the residual limb and is the likely cause of daily and chronic skin changes observed in pin users.

“…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.''…”

Promontory Sign in a Reactive Benign Vascular Proliferation

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.

“…16 Repeated microtrauma to the skin of the stump may occur if the fit of socket and stump is not perfect, leading to proliferation of fibroblasts and small vessels and in particularly sensitive tissue such as the skin on an amputation stump. 17 Acroangiodermatitis occurring on amputation stumps because of socket prostheses is clinically reported as a stump edema with violaceous macules, patches and nodules. 2,16,17 There is one report of amputation stump dermatitis, clinically resembling verrucous hyperplasia, but with predominant histologic aspects of acroangiodermatitis in a patient with a suction-socket lower limb prosthesis.…”
