Bilateral Thoracic Zosteroid Spreading Marginate Telangiectasia—Probably a Variety of “Carcinoma Erysipelatodes” (C. Rasch)—Associated with Unilateral Mammary Carcinoma, and Better Termed “Carcinoma Telangiectaticum”

Acquired generalized asymptomatic livid erythema and telangiectasia

“…Other patterns of metastasis are the commonly occurring nodular form and alopecia neoplastica [3]. Affecting roughly 20 % of cases, the telangiectatic variant of cutaneous metastasis described here was first reported by Parkes Weber in 1933 [4]. The clinical appearance, with bright red erythema and prominent telangiectases, is caused by tumor cell thrombi occluding dermal capillaries and lymphatic vessels (Figure 2).…”

Atypical case of telangiectatic metastatic breast carcinoma presenting as purpura

“…The most common manifestation is nodules, which are often found on the chest wall. Carcinoma telangiectaticum is rare, with only a few cases reported in the literature 5, 6, 7, 8, 9, 10…”

“…Histologically, tumor nests are found in dilated small blood vessels, mainly in the subepidermal zone in carcinoma telangiectaticum 9, 10. Blood vessels in the lower dermis may occasionally be involved.…”

“…Some cases of carcinoma erysipeloides, which is another type of inflammatory carcinoma, have also been reported previously. Both carcinoma erysipeloides and telangiectaticum are characterized by the intravascular spread of tumor cells in the dermis 10 . In carcinoma erysipeloides, tumor cells involve the lymphatic vessels in the dermis, whereas in carcinoma telangiectaticum, the tumor cells are spread mainly within the lumen of blood capillaries 10 .…”

In carcinoma erysipeloides, tumor cells involve the lymphatic vessels in the dermis, whereas in carcinoma telangiectaticum, the tumor cells are spread mainly within the lumen of blood capillaries 10 . In 2009, Marneros et al 5 reviewed 100 skin biopsy specimens from cutaneous breast cancer metastatic lesions obtained from patients seen at their dermatopathology unit between 1999 and 2008.…”
