Zosteriform metastases from colon carcinoma: an unusual pattern

Abstract

Cutaneous metastases of internal malignancies occur infrequently and the zosteriform spread of the skin lesions represents a rare entity. We report here a case of cutaneous metastases from a colon carcinoma clinically mimicked Herpes varicella-zoster. The literature is also reviewed.

A unilateral zosteriform cutaneous eruption on the lower extremity

“…We hypothesize that this cutaneous spread has likely been favored by a particular adhesion molecule expression pattern, although we ignore the exact pathogenesis. To our knowledge, only five cases of cutaneous metastatic colorectal adenocarcinoma in a zosteriform pattern have been reported to date 2,4,5 . This case is especially peculiar because it simulated a zosteriform pattern clinically and a lymphovascular spread histologically.…”

“…Tumoral cutaneous spread in a zosteriform‐like pattern is a very rare cutaneous manifestation of internal malignancies, with less than 100 cases reported in the literature 2,4,5 . The most common underlying neoplasm is breast adenocarcinoma 2 .…”

Zosteriform cutaneous metastases with primary endometrial carcinoma

“…[ 1 ] Clinically, metastases are localized in proximity to the underlying internal carcinoma. [ 4 10 ] In this reported case, the possible pathomechanism was lymphatic spread and spread along the dorsal nerves from the vicinity of vertebral metastases.…”

“…[ 3 ] The zosteriform pattern of distribution of these lesions is an exclusive and an even rarer form of presentation. [ 4 ] The most common primary for cutaneous metastasis is breast cancer in women and lung cancer in men. [ 5 ] Cutaneous metastases from endometrial adenocarcinoma are rare and when present are often associated with poor prognosis.…”

Zosteriform lymphangitic metastases of eccrine porocarcinoma

“…Zosteriform presentation of papules and plaques have been reported in several kinds of skin diseases, such as sporotrichosis, leishmaniasis, seborrheic keratosis, palisaded-encapsulated neuroma, eccrine spiradenoma, cutaneous leiomyoma, zosteriform cutaneous metastases from malignant tumor, and so on.
